Morphological characterization and genetic diversity analyses of plant traits contributed to grain yield in maize (Zea mays L.)
Abstract
Genetic variability and divergence among landraces and cultivars are invaluable resources that lead the breeder to understand the performance of an attribute or genotype, which possess paramount importance in selecting suitable genotypes or traits for hybridization programme. Thirteen maize genotypes were used to estimate the genetic parameters, variability, correlation and path coefficient, principal component analysis (PCA) and cluster analysis. The analysis of variance showed the presence of highly significant morphological variation among the thirteen genotypes. The phenotypic coefficient of variation (PCV) was greater than the genotypic coefficient of variation (GCV) for all the traits studied indicating their interaction with the environment to some extent. Most of the plant traits under study showed high heritability estimates, >60%. The high heritability (91.35%, 86.73%, 61.79% and 96.41%) coupled with high genetic advance (34.45, 107.98, 90.93 and 55.92) and genetic advance in percentage of mean (87.64%, 305.77%, 34.08% and 59.01%) were observed in plant height, kernel numbers row-1, thousand kernel weight and yield per plant; respectively, that designate the role of additive gene expression for these traits which would facilitate better scope for improvement of these traits through direct selection. The correlation analysis exhibited significant positive associations between yield per plant and plant height (0.603), ear girth (0.518), kernel numbers row-1 (0.509), thousand kernel weight (0.806) and kernel width (0.715). Besides it showed a significant positive correlation of thousand kernel weight with plant height (0.583), ear girth (0.590) and kernel width (0.794). Furthermore, the positive direct effects of ear girth (0.749), kernel number row-1(0.771), thousand kernel weight (0.356) and kernel width (0.291) on yield per plant were observed through path analysis. While plant height, ear length, kernel rows ear-1 and kernel length showed negative direct effect on yield per plant. The PCA showed that the first four principal components (PCs) accounted for more than 80% of total variation where PC1 explained 38.9% of total variability which was dominated by thousands kernel weight (0.448), yield per plant (0.444), kernel width (0.381), plant height (0.38), ear girth (0.378) and kernel rows ear-1 (0.318). Cluster analysis exhibited three distinct clusters with five genotypes in cluster I and cluster II, and three genotypes in cluster III. The cluster I having the genotypes BHM-15, BHM-13, BHM-12, BHM-9 and BHM-7 was loaded with the highest mean values of thousand kernel weight (339.67), yield per plant (121.33) and kernel width (9.20). Moreover, these genotypes showed close proximate with kernel width, thousand kernel weight, ear girth, plant height and yield per plant in PCA biplot. Therefore, the analysis of variance, principal component and cluster analyses revealed the presence of wider diversity in the studied maize genotypes. The findings of this study would be useful to select the potential traits and genotypes for further breeding programs to increase the grain yield in maize.

Eco friendly management of major Lepidopteran insect pests of summer cabbage by six commonly used botanicals
Abstract
The production of cabbage is highly influenced by the attack of insect pests and the infestation of insects is higher in the summer season. Among the insect pests, Lepidopterous insects play a vital role in the decreased production of cabbage. The response of major Lepidopterous insects to some commonly used botanicals was investigated under the present study on summer cabbage. Seven treatments, viz. T1 (Mahogany seed kernel extract @ 3.0 ml/L of water); T2 (Tobacco leaf extract @ 3.0 ml/L of water); T3 (Garlic extract @ 3.0 ml/L of water); T4 (Neem leaf extract @ 3.0 ml/L of water); T5 (Neem seed kernel extract @ 3.0 ml/L of water); T6 (Neem oil @ 3.0 ml/L of water) and T7 (untreated control) were used and applied at seven days interval. Among the management practices, the lowest mean infestation of cabbage leaf by semi-looper (4.79 leaves/5 plants), cabbage caterpillar (6.25 leaves/5 plants) and diamondback moth larvae (4.39 leaves/5 plants) was found in T6 that reduced highest leaf infestation over control (59.40%, 61.73%, and 68.03% respectively); whereas the highest mean infestation by semi-looper (11.80 leaves/5 plants), cabbage caterpillar (16.33 leaves/5 plants) and diamondback moth larvae (13.73 leaves/5 plants) was recorded in T7. The highest diameter and height of cabbage head was found in T6 (21.58 cm and 10.23 cm respectively); whereas the lowest was found in T7 (14.87 cm and 7.10 cm respectively). The highest single head weight (1.46 kg) was found in T6 that provided the highest total yield (36.50 t ha-1). On the contrary, the lowest single head weight and total yield were recorded in T7 (0.94 kg and 23.08 t ha-1 respectively). So, Lepidopterous insects of summer cabbage could be managed by using botanicals judiciously that would be safe for the health concerns of farmers as well as the consumers.

Impact of natural substances and synthetic hormone on grapevine cutting
Abstract
Application of synthetic rooting hormone has been recognized successful but expensive, so need to improve the knowledge of vegetative propagation with using natural substances. This experiment was conducted to study the effect of natural substances and synthetic hormone on rooting and vegetative growth of grapevine cutting. The study comprised of six treatments: (i) no hormone application (control), (ii) Aloe vera gel, (iii) Cinnamon powder, (iv) Undiluted honey, (v) Indole-3-Butyric acid (IBA) and (vi) Indole Acetic acid (IAA). Data on survival ability; vegetative growth and rooting were taken. The results showed that the highest survival percentages and root number observed for synthetic hormone (IBA) which was close to natural substance (Aloe vera gel) treatment. On the other, Aloe vera gel treatment significantly higher than other treatments in terms of vine length, vine diameter, root length and SPAD value. Therefore, natural substances like aloe vera gel treatment could be the effective root hormone for rooting of grape vine cutting.
Key Words: Phytohormone, IAA, IBA, Aloe vera gel, Cinnamon and Honey.

Molecular analysis of the isolated probiotic microorganisms from yoghurt samples, distributed in Khulna and Chittagong City of Bangladesh, using RAPD marker
Abstract
Yogurt is among the most common dairy products being consumed around the world. During the last decade, probiotics have become an important trend and being used as a useful component regarding the development of functional foods and as substitutes of antibiotics. Probiotics are living, non-pathogenic microorganisms which has profuse beneficial health benefits. The study was aimed at isolation, DNA extraction and finally, molecular characterization using RAPD based PCR from 10 yogurt samples from Khulna and Chittagong Divisions of Bangladesh. Four random 10-mer RAPD primers viz. OPA 2, OPA 5, OPA 9, and OPA 18 were used for amplification. Among them, OPA 18 showed the highest number of amplified bands. The RAPD profiles were demonstrated by Neighbor-joining algorithms. According to the phylogenetic tree, the pair having lower genetic distance was closely related and made cluster. The analysis manifested that, the genetic distance value ranged from 0.14286 to 0.85714. Both genetic distances and dendrograms were determined by using PAUP software. Although most RAPD fragments were common to all ten isolates, where a lower number of polymorphic fragments (lower genetic diversity) were observed that allowed the clear distinction of the isolates. The results indicate that RAPD analysis could be a useful tool to study the molecular landscape on regional native probiotics of Bangladesh.

Adoption determinants and constraint of BRRI released Aman rice varieties: Evidence from Mymensingh District
Abstract
This study investigates the prospect and constraint of BRRI developed Aman rice varieties in Bangladesh. To address the objective 13 Upazila of Mymensingh district selected purposively. Farm-level data was collected through farmers’ group discussions (FGD) with the key informants and face to face interviews for household surveys. A multistage random sampling technique was adopted in selecting the 780 respondents. Moreover, in total, twenty-six FGDs and interviews of experts were conducted to generate in-depth data and validation of data about the adaptation dynamics of rice varieties in the Aman season. Both the descriptive and inferential statistics were used to process the data. A censored Tobit model was used to measure the adoption intensity of BBRI released Aman varieties. The empirical findings of the study show that farmers adopted about 68 percent of BRRI varieties followed by indigenous (15.6%), other MVs (10.2%), Indian (5.5%), and hybrid (1.3%). Moreover, susceptibility biotic and abiotic stresses, longer growth duration, and unavailability of quality seed were the major reasons for decreasing adoption. But still now among the farmers, the popularity of BRRI varieties has higher. The model result reveals that family size, farm size, easy access to extension services, and better market demand along with higher yield potential, good appearance, higher price, and good taste to eat had a positive significant influence on the widespread adoption of BRRI cultivars in Mymensingh district. Therefore, in the process of varietal development, to develop and disseminate, researchers must consider the preferences of the rice value chain actors and the agro-climatic conditions of the regions. In this regard, due consideration should be given to increased yield potential, biotic, and abiotic stress-tolerant, short to medium growth duration, good market demand.

Biology of the cucurbit fruit fly, Bactrocera cucurbitae (Coq) on host bottle gourd, Lagenaria siceraria
Abstract
We investigated the biology of the cucurbit fruit fly, Bactrocera cucurbitae (coq) on bottle gourd, Lagenaria siceraria, using variety ‘BARI-Lau 1’. The mean incubation period, larval (1st, 2nd and 3rd instars), pre-pupal, pupal and total developmental periods of B. cucurbitae were 1.69±0.28, (1.72±0.33, 1.41±0.31, 2.31±0.51), 0.74±0.28, 9.2±0.78 and 36±1.69 days, respectively. The mean adult longevity, with food and without food was 14.1±1.28 and 5.0±0.81 days, respectively. The lengths of all three larval instars were 1.1± 0.9, 3.03 ± 0.95 and 6.42 ± 0.90 mm, and the widths were 0.22 ±0.11, 1.12 ± 0.01 and 2.13 ± 0.20 mm, respectively. The length and width of the pre-pupa and the pupa were 5.86 ±0.48, 5.68± 0.26 mm and 1.94 ± 0.23, 2.39±0.20 mm respectively. The length of male and female were 6.61±0.59 and 8.28±0.52 mm. The widths of males and females with wingspan were 10.97 ± 0.43 and 13.02±1.28 mm respectively. The incidence of B. cucurbitae as maggot population in bottle gourd was higher in January during the study period from December 2018 to March 2019.

Growth and yield response of Broccoli to vermicompost and farmyard manure
Abstract
The present experiment was carried out at Agricultural Research field, Noakahali Science and Technology University, Noakhali, Bangladesh during the period from September 2018 to February 2019 to find out the effects of Vermicompost and Farmyard manure growth and yield of Broccoli. The single factor experiment was carried out by Randomized Complete Block Design (RCBD) with three replications. Three treatments viz., T0= Control, T1= Vermicompost and T2= Farm Yard Manure as well as Centeuro variety were used. Data were recorded from different stages of plant growth on plant height at different days after transplanting, number of leaves/plant, leaf length, leaf diameter, plant spread, 50% curd initiation days, 50% curd maturation days, curd diameter, Marketable curd weight, Net curd weight and Yield/plot. All the recorded parameters were statistically significant among the treatments. The tallest plant (43.67cm) can be recorded from T1 (vermicompost) whereas lower plant height (38.10cm) was notified from control (T0). The maximum number of leaves (16.03) recorded from vermicompost treated plant where minimum from control (T0; 13.28). Highest leaf length (40.67cm), leaf diameter (16.22cm), plant spread (47.91cmü), early curd initiation (73.22 days), early curd maturation (89.72 days), curd diameter (16.16cm), marketable curd weight (452.67g), net curd weight (361.43g) and yield/plot (3.94kg) was found from vermicompost treated plant is compared with Farmyard manure whereas lowest data recorded from control. Observing the results it can be stated that using of vermicompost treated plants gave better growth and yield contributing characters of Broccoli in contemporary with other treatments.

Effect of different time of bagging for ensuring quality mangoes Cv. Mishribhog
Abstract
Fruit bagging is a newly developed technology, widely used by the farmers, easy practice, and environment friendly and useful for high quality mango production in Bangladesh Four treatments were included in this experiment namely non-bag (control); white polythene bag; single layered white paper bag and double layered brown paper bag. The fruits were bag at 35, 45 and 55 days after fruit set. The experiment was carried out in the Randomized Complete Block Design with three replications. Fruit bagging has direct effect on fruit length, diameter, fresh weight and pulp weight (9.49cm, 8.31cm, 295.8g and 267.4g, respectively) while minimum was recorded in non-bagged control fruits (7.75cm, 6.91cm, 211.1g and 182.0g, respectively) at 35 and 45 days. In addition, the total sugar, reducing sugars, total soluble solid, ascorbic acid, pH and β-carotene were improved over control fruits. Brown paper bags are competent to change the fruit color. Brown paper bag extended shelf life up to 9 days with premier sensory quality as against 5 days of non-bagged control fruits. Considering the results, double layered brown and single layered white paper bagged fruits performed the best in respect of quality parameters and extending shelf life in mango cv. Mishribhog.

Push-Pull Strategy: an integrated approach to manage insect-pest and weed infestation in cereal cropping systems
Abstract
The “Push–Pull” strategy is an effective, efficient, and powerful tool in integrated pest management (IPM) that is combining several behaviour-modifying stimuli to control cereal stem borers and the noxious weed Striga in cereal-based farming systems in Africa. This technology involves driving away from the cereal stemborers from the main crop by using stimuli of repellent intercrops (push) that mask host apparency and simultaneously stemborers are attracted by highly apparent and attractive stimuli from trap plants (pull). The fodder legume, Desmodium (D. uncinatum and D. intortum), and Molasses grass (Melinis minutiflora) are used as the repellent intercrop, which is repugnant to stemborer moths. On the other hand, Napier grass (Pennisetum purpureum) and Sudangrass (sorghum vulgare sudanese) is planted as a border crop used as the trap plant (pull). Chemicals that are released by the roots of the Desmodium intercrop induce abortive germination of seeds of noxious Striga weeds, providing very effective control of this weed. Napier grass and Molasses grass also provide high-value animal fodder that facilities milk production, diversifying sources of farmers’ income. Besides, this technology helps to improve soil fertility and prevent soil erosion that leads to increased grain yield in the future. Chemicals that are released by the roots of the Desmodium intercrop induce abortive germination of seeds of noxious Striga weeds, providing very effective control of this weed.
Key Words: Push–Pull, Stemborers, Striga, Attractants, Repellent and Integrated Pest Management (IPM).

Site specific nutrient management and its effect on growth and yield of winter maize
Abstract
An experiment was conducted on farmer’s field in Khajura, Banke for site specific nutrient management (SSNM) in hybrid maize (Rajkumar) during winter season of 2016. The climatic condition of the experimental location was humid sub-tropical and sandy loam soil occurring intense summer and severe winter. Average annual rainfall of 1000 -1500 mm occurs in the location. The experiment was replicated 4 times in Randomized complete block design having plot size of 4.8 x 3 m2. Row to row spacing was maintained at 60 cm and plant to plant at 25 cm for each plot. There were six treatments including farmers fertilization practice (27.6:27.6:18 NP2O5K2O kgha-1) as a check, recommended dose of fertilizer (160:60:40 NP2O5K2O kgha-1), site specific nutrient management (212.9:66.8:280.8 NP2O5K2O kgha-1), 75% SSNM (372.6:116.9:491.4 NP2O5K2O kgha-1), FP-N, FP-P, SSNM-K (27.6:27.6:280.8 NP2O5K2O kgha-1) and SSNM-N, FP-P, FP-K (212.9:27.6:27.6 NP2O5K2O kgha-1). Among the treatment combination; application of SSNM we can increase the yield by 193% over farmer fertilization practice. Recommended dose of fertilizer and 75 percent SSNM also increase the yield by 138% and 130.4% respectively compared to farmer fertilization practice. 88% and 53.5% more increment could also be obtained through the application of only SSNM dose of nitrogen and SSNM dose of potassium respectively over farmer fertilization practice.
