Influence of micronutrient (boron) for the growth and yield of cauliflower
Abstract
A field experiment was conducted at the Horticultural farm, Sher-e-Bangla Agricultural University, Dhaka-1207 during the period from October 2015 to February 2016 with micronutrient Boron applied to cauliflower cultivar, ‘F1 hybrid’. Four treatments viz., B0: Control, B1: 1kg ha-1, B2: 1.5kg ha-1, B3: 2kg ha-1 was utilized in this experiment which was arranged in Randomized Complete Block Design with three replications. Maximum Plant height (41.66 cm), Leaf number (19.35), Leaf area (182.51 cm2), 50% curd initiation (47.23 days), pure curd weight (698.20 g), curd weight with leaves (1.56 kg), curd yield plot-1 (1.53 kg) and curd yield ha-1 (15.30 t) at harvest was found at B3 treatment while lowest was (14.28 cm, 6.33 leaves, 121.85 cm2, 48.44 days, 418.60 g, 1.07 kg, 1.05 kg, 10.49 ton ha-1 respectively) was recorded from control. Therefore, result indicates that application of micronutrient (Boron) in supplement with recommended fertilizer at 2 kg ha-1 will successfully increase growth and yield of cauliflower.

Energy use pattern in wheat production in the Gezira and Rahad Schemes, Sudan
Abstract
This study was conducted to investigate the energy use pattern for wheat production in the Gezira and Rahad Agricultural schemes, Sudan in relation to various aspects of energy consumption. Input data and yield of wheat were collected from the record of the schemes. Results showed that the total energy inputs and output of wheat were 13493.36 and 71038.75 MJ/ha, respectively. Based on these results the amount of energy use efficiency and the specific energy were 5.26 and 14.91, respectively, and the amount of energy productivity and net energy were 0.203kg/MJ and 57545.39MJ, respectively. The share of renewable energy as one of the sustainability indexes of agricultural systems was 21.54% (man labor and seeds) and 78.46 nonrenewable (fuel, chemicals, machinery and water). 40.27% was direct energy (human labor, fuel and water) and 59.46 as indirect energy (seeds chemicals and machinery). Therefore, for sustainability, the country should increase the share of renewable energy through using animal manure and agricultural residue compost.

Varietal Screening of Mungbean against Whitefly and Aphid
Abstract
The experiment was conducted for varietal screening of mungbean against sucking insect pest whitefly (Bemisia tabaci) and aphid (Aphis gossypii). Different mungbean varieties i.e. BARI Mung-1, BARI Mung-2, BARI Mung-3, BARI Mung-4, BARI Mung-5 and BARI Mung-6 were used as treatment for this study. The experiment was laid out in Randomized Complete Block Design (RCBD) with three replications. Data on different parameter were recorded and statistically significant variation was observed for different varieties. Among the varieties, BARI Mung-6 showed the least whitefly and aphid population and highest resistance against whitefly and aphid infestations at different stages than all other varieties. The highest seed yield (1.82 t ha-1) was recorded from BARI Mung-6, while the lowest (1.30 t ha-1) was recorded from BARI Mung-4. It means that BARI Mung-6 were superior to other varieties in terms of lowest whitefly and aphid infestation and maximum yield.
Key Words: Mungbean, Infestation, Resistance, Whitefly, Aphid.

Effects of Bradyrhizobium on growth nodulation and nitrogen uptake by akashmoni
Abstract
Bacteria were isolated and characterized from the root nodules of Akashmoni (Acacia nilotica) to study their effects on growth parameters, nodulation and N uptake by sapling of Akashmoni. Five isolates were obtained from Akashmoni and were identified them as Bradyrhizobium on the basis of their colony, morphological and biochemical characteristics. A pot experiments were conducted by using 6 treatments, comprising 5 isolates of Bradyrhizobium and an uninoculated control to evaluate the performance of the isolates. The experiment was laid out in a Completely Randomized Design (CRD) with 3 replications. Statistically higher values for all the parameters were obtained from Bradyrhizobium inoculation over uninoculated control (T1) except leaf number plant-1 at 30 DAS. The highest value of plant height (cm plant-1) and leaf number plant-1 at 60 DAS were recorded as 30.33 cm plant-1 and 12.67 plant-1, respectively due to the treatment T3 (AN-R-2). The highest nodule numbers plant-1 and dry weight of nodule (mg plant-1) were also noted as 134.7 plant-1 and 76.6 mg plant-1 for the same treatment. The highest root, shoot and total dry matter yields of Akashmoni were also found for the same treatment T3 (AN-R-2). The total dry matter yield of Akashmoni was increased by 149, 198, 144, 55 and 82 % over control due to T2 (AN-R-1), T3 (AN-R-2), T4 (AN-R-3), T5 (AN-R-4) and T6 (AN-R-5), respectively. The total N in shoot showed a similar pattern and corresponding increase in N uptake by shoots were 191, 396, 285, 80 and 242 %, respectively. Considering all the parameters the isolate T3 (AN-R-2) showed the best performance.

Morphological based screening and genetic diversity analysis of the local rice (Oryza sativa L.) landraces at the seedling stage for salinity tolerance
Abstract
Salinity is considered as one of major threats in rice production around the world. This experiment was conducted to screen out the salt tolerant rice genotypes following modified hydroponic method and IRRI standard protocol (SES scoring). Twenty-five rice genotypes were evaluated for the screening purpose for salinity tolerance considering morphological parameters. Three levels of salinity treatments (EC-0 dSm-1, EC-7 dSm-1 and EC- 12 dSm-1) were used for the phenotypic analysis and genotypes were categorized according to SES scoring based on visual salt injury in rice seedlings at 21th days of saline treatment. Salt injury symptoms varied among the landraces with different concentration of salt. All plant parameters reduced significantly in all genotypes with increasing salinity although less reduction was found in some genotypes at higher salinity also and identified those genotypes as salt tolerant. After 21 days of salinization, five genotypes (Maloti, Chinisagor, Lal bat, Moyna, Binadhan-8 and Binadhan-10) were found as slat tolerant at both 7 dSm-1 and 12 dSm-1 according to standard evaluation score based on visual salt injury at seedling stage. The phenotypic co-efficient of variation (PCV) was higher than genotypic co-efficient of variation (GCV) for all the traits studied indicating that they all are interacted with the environment to some extent. The highest heritability was found for all traits in the range of 73.82% to 96.08% indicating that the traits are less influenced by environment and these traits can be considered for the improvement of salinity tolerance. High heritability coupled with high genetic advance as percent of mean was observed for standard evaluation score (96.08%, 130.51%), root dry weight (95.72%, 135.08%) and shoot fresh weight (94.63%, 68.38%) indicating the role of additive gene expression for these traits and would facilitate better scope for improvement of these traits through direct selection. The correlation and path analysis showed that live leaves (%), survival rate (%), shoot length, chlorophyll content, root fresh weight, root dry weight had significant negative correlation with standard evaluation score as well as had direct positive effect on standard evaluation score indicating their importance for the improvement of salt tolerance ability of plant.

Diallel analysis and estimation of heterosis in single cross maize hybrids
Abstract
Salinity is considered as one of major threats in rice production around the world. This experiment was conducted to screen out the salt tolerant rice genotypes following modified hydroponic method and IRRI standard protocol (SES scoring). Twenty-five rice genotypes were evaluated for the screening purpose for salinity tolerance considering morphological parameters. Three levels of salinity treatments (EC-0 dSm-1, EC-7 dSm-1 and EC- 12 dSm-1) were used for the phenotypic analysis and genotypes were categorized according to SES scoring based on visual salt injury in rice seedlings at 21th days of saline treatment. Salt injury symptoms varied among the landraces with different concentration of salt. All plant parameters reduced significantly in all genotypes with increasing salinity although less reduction was found in some genotypes at higher salinity also and identified those genotypes as salt tolerant. After 21 days of salinization, five genotypes (Maloti, Chinisagor, Lal bat, Moyna, Binadhan-8 and Binadhan-10) were found as slat tolerant at both 7 dSm-1 and 12 dSm-1 according to standard evaluation score based on visual salt injury at seedling stage. The phenotypic co-efficient of variation (PCV) was higher than genotypic co-efficient of variation (GCV) for all the traits studied indicating that they all are interacted with the environment to some extent. The highest heritability was found for all traits in the range of 73.82% to 96.08% indicating that the traits are less influenced by environment and these traits can be considered for the improvement of salinity tolerance. High heritability coupled with high genetic advance as percent of mean was observed for standard evaluation score (96.08%, 130.51%), root dry weight (95.72%, 135.08%) and shoot fresh weight (94.63%, 68.38%) indicating the role of additive gene expression for these traits and would facilitate better scope for improvement of these traits through direct selection. The correlation and path analysis showed that live leaves (%), survival rate (%), shoot length, chlorophyll content, root fresh weight, root dry weight had significant negative correlation with standard evaluation score as well as had direct positive effect on standard evaluation score indicating their importance for the improvement of salt tolerance ability of plant.

Variability, correlation and path analysis in drought tolerant rice (Oryza sativa L.)
Abstract
Yield contributing traits in thirty three rice genotypes were studied for variances, heritability, correlation (genotypic and phenotypic) and path coefficient analysis. The highest phenotypic variation (σ2p), was found for No. of grain per panicle and the lowest was observed in 100 grain wt. High genotypic coefficient of variation (GCV) and phenotypic coefficient of variation (PCV) for No. of unfilled grains per panicle, No. of grains per panicle and grains yield per hill, indicated that selection of these traits would be effective. The high heritability estimates along with low genetic advance indicates that non-additive type of gene action and genotype-environment interaction plays a significant role in the expression of the traits as observed in days to 50% flowering, No. of tillers per hill days to harvesting and panicle length (cm). No. of grains per panicle with grains yield per hill as well as length showed significant and positive correlation but No. of tillers per hill showed highly significant and negative correlation with days to 50% flowering both at genotypic and phenotypic level. Path coefficient analysis showed that No. of grains per panicle had maximum direct effect on grain yield followed by No. of panicles per hill, and No. of tillers per hill. The lowest direct effect on grain yield was exhibited by No. of unfilled grains (0.0732) followed by plant height, No. of primary branches per panicles, and No. of secondary branches per panicles respectively. Number of grains per panicle had maximum direct effect on grain yield followed by No. of panicles per hill and No. of tillers per hill. The results prescribed that there is a highly significant positive correlation with positive direct effect was observed in No. of grains per panicle, No. of panicles per hill, No. of unfilled grains per panicle, No. of primary branches and No. of secondary branches.
Key Words: Genetic variability, heritability, character association, and path coefficient analysis

Status of household food insecurity in Bajura district of Nepal
Abstract
Food insecurity is a condition of limited food availability owing to a lack of money and resources.The study examined the household food insecurity status along with its affecting factors in Bajura district Nepal. Purposive and simple random sampling procedure was used in selecting 120 household respondents of Budhiganga and Triveni Municipality. Data were collected during June-July 2018 with the use of interview schedule and structured and semi-structured questionnaires. The Household Food Insecurity Access Scale was used to assess the food insecurity status. The result revealed that 55% of the households were food insecure comprising 33.34%, 15% and 6.66% as mildly, moderately and severely food insecure respectively. Similarly, ordered Probit regression model was used for assessing determinants of household food insecurity using the Household Food Insecurity Access Scale as the dependent variable which showed that average annual income, amount of rice, family size, and distance to nearby market were found significantly determining the food insecurity level. The months of March, June and July were found most shortage for food grains in the study area. The identified constraints were drought, rare use of improved farm technology, low farm and off farm income and poor agriculture extension services leading to food shortage. The study recommends on agricultural policies aiming at promoting farmers access to irrigation facility, improving farm household productivity and market access as well as farmers be provided with extension services and non-farm income generating activities.

Wet rice straw ensiling with biogas slurry: A prospective feed preservation technique for higher protein content and metabolizable energy
Abstract
Bio-slurry, a byproduct of biogas plant is not using properly and most of the cases causing environmental and social hazard by discharging it in public places though it rich in nutrients especially protein (16-20% CP) and produced through beneficiary anaerobic microorganisms. On the other hand, Straw is highly fibrous residue having low protein (CP <3%) content which mostly indigestible. The poor digestibility of straw is further caused by the presence of high amount of inhibitory mineral element called silica. The combination of low intake, low degradability, low nitrogen content and an imbalanced mineral composition means that rice straw alone may not even meet the animal’s maintenance needs. Therefore, the animals are suffering from nutrients deficiencies resulting in poor health and productivity of these animals reared on straw based ration. Under this situation, it is essential to find out the ways and means to increase the supply and quality of feed to livestock to fulfill their deficiencies. So, the way to improve the crude protein, metabolizable energy and preservation quality, wet rice straw can be ensiled with biogas slurry. The principles of ensiling process of straw are maintenance of anaerobic conditions throughout the ensiling and rapid decline in pH value by lactic acid bacteria. Ensiling of wet rice straw along with biogas slurry may produce a good quality ensilage for feeding cattle having desire palatability, nutrient content and digestibility and also reduce the environmental pollution.
Key Words: Biogas slurry, Wet rice straw, Protein content, Metabolizable energy, Feed preservation technique and Future prospects.

Effects of conservation agriculture on crop and system productivity and profitability under maize based system in far western Nepal
Abstract
Intensive conventional tillage practices in Doti district, far western Nepal has been experiencing low crop productivity and profitability. A shift towards conservation agriculture (CA) practices improve the crop production and farmer’s net income. This research assessed the effects over two consecutive years (2014/15– 2015/16) of CA system on crop and system productivity and profitability of different maize-based cropping system. This study under split-split plot design with four replications examined the effects of two cropping systems (Maize-wheat-mungbean and maize-lentil-mungbean), two cultural practices (CA and conventional agricultural practices) and four varietal sequences (Rajkumar-Dhaulagiri and Shimal-Pratikshya, Rajkumar-WK 1204 and Khajura1-Pratikshya, Arun2-Dhaulagiri and Shimal-Kalyan and Arun 2-WK 1204 and Khajura1-Kalyan). Results showed that cereal-cereal-legume cropping system, CA practices and varietal sequence of Rajkumar-WK 1204-Pratikshya produced 10.87% higher system yield (12.85 t ha-1yr-1) than conventional agricultural practices (11.59 t ha-1yr-1), 83.47% higher system net benefit (1554 US$ ha-1yr-1) than conventional agricultural practices (847 US$ ha-1yr-1) and 7.76% higher maize equivalent yield (17.08 t ha-1yr-1) than conventional agricultural practices (15.85 t ha-1yr-1). Similarly, cereal-legume-legume cropping system, CA practices and varietal sequence of Rajkumar-Khajura1-Pratikshya produced 19.62% higher system yield (9.39 t ha-1yr-1) than conventional agricultural practices (7.85 t ha-1yr-1), 139.39% higher system net benefit (1594 US$ ha-1yr-1) than conventional agricultural practices (666 US$ ha-1yr-1) and 12.70% higher maize equivalent yield (16.50 t ha-1yr-1) than conventional agricultural practices (14.64 t ha-1yr-1). Therefore, farmers should apply cereal-cereal-legume cropping system (irrigated condition), cereal-legume-legume cropping system (rainfed condition), CA practices and varietal sequence of Rajkumar-WK 1204-Pratikshya and Rajkumar-Khajura1-Pratikshya for higher system productivity and profitability.

Abstract
Intensive conventional tillage practices in Doti district, far western Nepal has been experiencing low crop productivity and profitability. A shift towards conservation agriculture (CA) practices improve the crop production and farmer’s net income. This research assessed the effects over two consecutive years (2014/15– 2015/16) of CA system on crop and system productivity and profitability of different maize-based cropping system. This study under split-split plot design with four replications examined the effects of two cropping systems (Maize-wheat-mungbean and maize-lentil-mungbean), two cultural practices (CA and conventional agricultural practices) and four varietal sequences (Rajkumar-Dhaulagiri and Shimal-Pratikshya, Rajkumar-WK 1204 and Khajura1-Pratikshya, Arun2-Dhaulagiri and Shimal-Kalyan and Arun 2-WK 1204 and Khajura1-Kalyan). Results showed that cereal-cereal-legume cropping system, CA practices and varietal sequence of Rajkumar-WK 1204-Pratikshya produced 10.87% higher system yield (12.85 t ha-1yr-1) than conventional agricultural practices (11.59 t ha-1yr-1), 83.47% higher system net benefit (1554 US$ ha-1yr-1) than conventional agricultural practices (847 US$ ha-1yr-1) and 7.76% higher maize equivalent yield (17.08 t ha-1yr-1) than conventional agricultural practices (15.85 t ha-1yr-1). Similarly, cereal-legume-legume cropping system, CA practices and varietal sequence of Rajkumar-Khajura1-Pratikshya produced 19.62% higher system yield (9.39 t ha-1yr-1) than conventional agricultural practices (7.85 t ha-1yr-1), 139.39% higher system net benefit (1594 US$ ha-1yr-1) than conventional agricultural practices (666 US$ ha-1yr-1) and 12.70% higher maize equivalent yield (16.50 t ha-1yr-1) than conventional agricultural practices (14.64 t ha-1yr-1). Therefore, farmers should apply cereal-cereal-legume cropping system (irrigated condition), cereal-legume-legume cropping system (rainfed condition), CA practices and varietal sequence of Rajkumar-WK 1204-Pratikshya and Rajkumar-Khajura1-Pratikshya for higher system productivity and profitability.
