Evaluation of some F1C7 clonal potato genotypes in Bangladesh
Abstract
An experiment was conducted at Breeder Seed Production Centre (BSPC), Bangladesh Agricultural Research Institute (BARI), Debiganj, Panchagarh during cropping seasons to investigate comparative potentiality of five clonal potato hybrids, 4.5 W, 4.15, 4.26 R, 4.27 and 4.40 for releasing as variety in the country. In the investigation two outstanding varieties, Diamant and Cardinal were used as check. All the genotypes under study expressed excellent plant vigour showing above seven score (at 1-10 rating scale). Plant height ranged from 58.73 to 68.20 cm. The highest tuber weight/hill was found at 4.26 R (763.7 g) which was statistically similar to 4.5 W (741.7 g) and 4.40 (670.3 g) while the lowest was found at 4.15 (537.7 g). The highest yield was found from clone 4.40 (29.57 t/ha) at 65 days after planting (DAP) which was statistically similar to all other genotypes except 4.27 (22.44 t/ha). Regarding yield the clones/varieties may be arranged in order to descending as 4.5 W (47.36 t/ha), 4.26 R (46.02 t/ha), 4.40 (44.69 t/ha), Cardinal (40.46 t/ha), 4.27 (40.23 t/ha), Diamant (39.81 t/ha) and 4.15 (35.83 t/ha). Among them clone 4.5 W and 4.26 R gave significant higher yield than Diamant and Cardinal. Therefore, these two genotypes could be selected for variety for Bangladesh condition with further trails in other parts of the country.

Identification of beta satellite component in (Hibiscus rosa-sinensis L.) through PCR-RFLP from Faisalabad, Pakistan
Abstract
Shoe flower (Hibiscus rosa-sinensis L.) is an ornamental plant belongs to the family Malvaceae. Due to its natural beauty and medicinal properties it is mainly grown in regions with tropical and subtropical environment. Shoe flower is known to infect by many diseases. Among all diseases Hibiscus leaf curl disease is caused by the begomovirus transmitted through Bemisia tabaci is very common and also an alternative host of cotton leaf curl disease due to the similar symptomology. In present study the identification of begomovirus in shoe flower was analyzed by using PCR-RFLP (Polymerase chain reaction- Restriction fragment length polymorphism). For this purpose, survey was conducted from seven different locations in university of agriculture Faisalabad. Plants were observed with virus symptoms of Hibiscus leaf curl disease such as upward curling of leaves, darkening and thickening of veins, stunting of plant size as well as leaf enation. For further molecular studies, DNA was isolated from all infected samples by using CTAB method and confirmed by Gel electrophoresis. PCR reaction amplified three DNA samples having beta satellite component, labeled (S3, S4 and S6) at 1.4 kbp. According to the (PCR-RFLP) analysis of three amplified samples, In BamH1 restriction enzyme, all the samples were restricted into 625 bp. In second restriction enzyme Pst1, DNA samples were restricted into 1.4 kbp. While in the case of ECOR1, fragment was restricted into 1.3 kbp.

Morphological Characterization of Guava Germplasm (Psidium sp.)
Abstract
Characterization of germplasm is important for crop improvement. An investigation was carried out with twelve guava germplasm to investigate morphological characters viz. leaf qualitative and fruit qualitative and quantitative characters. The single factor experiment was conducted in randomized complete block design (RCBD) with three replications. Maximum fruit length was found in Chiangmai long (9.37 cm) and minimum was found in Sawadi (4.43 cm). The highest number of seeds was observed in Chiangmai round (352.80). Number of Seed was lesser in Kanchan Nagar (196.40) and in BAU-5 (200.80). Analysis of variance for different characters showed high degree of variation among the germplasm. Among the germplasm BAU-1, BAU-5, Chiangmai long, Chiangmai round, Mukundapuri and Poly guava were found superior according to size, taste, sweetness and so on. The variability in these characters generated valuable information could be used for choice of parents for advance guava breeding programme.

Effect of elevated temperature on growth and yield of rice in central hill of Nepal
Abstract
Climate change and its consequences have severely affected Nepalese agriculture. The higher temperature in the lower elevations of the tropical region as well as lower temperature in the higher elevations has adversely affected rice cultivation. Therefore, to evaluate the performance of different rice genotypes in central hills present experiment was carried out at Nepal Agricultural Research Council, Khumaltar, Lalitpur, Nepal in 2017 A.D. under irrigated main season rice system. Split Plot design with three different heights of plastic chamber (Chamber with height of 4', 5'4" and 6'9") and one open field as a main plot factor and four different rice genotypes (Khumal 10, NR 1105 B-B- 27, Khumal 8, 08 Fan-10) as a sub plot factor were used. 25 days seedlings were transplanted in 12 m2 plot area in July 1, 2017 at 20×20 cm spacing. The result showed that the temperature increments inside the chamber have not significantly influenced the yield of rice. Within 4 rice genotypes, Khumal 10 and Khumal 8 were found to produce significantly higher yield.

Effect of NPK fertilizers on seedling growth of mangrove species
Abstract
An experiment was conducted to assess the effect of nitrogen, phosphorus and potassium (NPK) fertilizers on seedling growth and survival of Heritiera fomes (sundri), Xylocarpus mekongensis (passur), Excoecaria agallocha (gewa), Ceriops decandra (goran) and Avicennia officinalis (baen) mangrove species of Bangladesh for nine months. Seedlings were raised in the nursery using plastic pots. NPK fertilizers with three treatments (control, 4 gm and 8 gm doses) were used two times when seedlings age was 3 and 6 months. The result showed that seedlings height growth of Excoecaria agallocha was enhanced significantly with the application of NPK fertilizers but it was shown negatively significant effect on height growth of Xylocarpus mekongensis after second time fertilizer application. Moreover, NPK application enhanced mortality of Avicennia officinalis and Ceriops decandra seedlings in both times of fertilizer application. But no effect of NPK fertilizers on seedlings growth and survival of Heritiera fomes were observed.

Influence of natura one and neem oil on growth and yield of brinjal (Solanum melongena)
Abstract
An experiment was accomplished at the horticultural farm, Sher-e-Bangla Agricultural University, Dhaka, Bangladesh during to evaluate the effect neem oil and natura one for brinjal production. The experiment conducted with four treatments viz. Control (T0), Natura-one (T1), Neem oil (T2) and Neem oil+ Natura one (T3) following Randomized Complete Block Design (RCBD) with three replicates. This study was carried out to examine different characters like plant height, number of branch, infested branch, branch infestation (%), number leaves/plant, chlorophyll percentage, number of flower/plant, number of fruit/plant, infested fruit, fruit infestation (%), yield/plant (kg), yield/ha (ton) and yield increase (%) over control of brinjal. Lower infested shoot and fruits (0.2 and 0.2 plant-1, respectively) and percentage (11.9 and 16.9, respectively) were found in T3. Highest yield (57.3 t ha-1) and increased yield percentage over control (13.47%) were also found in T3 treatment. In view of overall performances, foliar application of neem oil and natura one has potentiality to combat the insect damage as well increase yield.

Germination and initial seedling growth performance of Vitex peduncularis Wall. ex Schauer – A threatened native tree species of Bangladesh
Abstract
Vitex peduncularis Wall. ex Schauer, locally known as Goda, is a threatened native tree species of Bangladesh. In addition to providing many other services this produces, timber of high density, which is traditionally, used for different construction activities. Though seed production is regular but natural germination of seeds is not satisfactory due to the hard seed coat. Effect of pre-sowing methods was studied to find out the best pre-sowing method for higher rate of V. peduncularis seeds germination. Randomly selected quality seeds were sown in propagator house with Sylhet sand media, in conventional polybags with 3:1 soil and cow-dung media, and in nursery beds with soil media only. Significantly (P<0.05) highest seed germination (46%) was observed in propagator house. The germination energy (7.9%), plant percent (31.5%) and germination value (147.2) were highest in the seedlings raised in polybags. These seedlings also exhibited better growth in the initial stage at nursery. The records of initial growth of the seedlings indicated highest shoot length (38 cm), root length (34.3 cm), node number (15) and leaf area (18.9 cm × 4.7 cm) for seedlings grown in polybags. Seedlings grown in polybags were more vigor and thrive better than the seedlings germinated in propagator house and nursery bed. This paper will be a supportive material for more advanced studies on seed germination and for establishing plantation with rare but valuable species by raising commercial nurseries.

Optimal economic return and rotation period of large scale Acacia auriculiformis plantations in Bangladesh
Abstract
Acacia auriculiformis (Akashmoni) has shown excellent performance under plantations and appropriate for quick economic return even on soil of low fertility. The present study highlighted on the maximum economic return and rotation period in different age series of A. auriculiformis plantations at different locations of Chittagong during May 2017 to April 2018. At 13% discounting rate, the study revealed maximum NPV (457,993 Tk), IRR (48%), BCR (6.20), and Le (277,425 Tk) in 10 years old strip plantations. Besides, negative NPV (-27535 Tk), IRR (-8%), and Le (-16888 Tk) were found in 4 years old block plantations. Here, both the plantation practices are profitable (BCR>1.00) except only for 4 years block plantation (BCR=0.6). However, if we consider only NPV, the rotation period should be fixed at 10 years and 14 years for strip and block plantations respectively. Therefore, the study revealed, if we consider IRR, BCR, Le to determine rotation interval of A. auriculiformis in Bangladesh, it should be fixed at 10 years and 12 to 14 years of strip and block plantations respectively. Hence, a large amount of production losses every year as crook and lean formation takes place due to use of low quality seeds and planting materials. However, different management practices is also required immediately for large-scale plantation programs of different regions of the country.

Effect of boron fertilization on yield and yield attributes of mustard var. BARI Sarisha-14
Abstract
Boron (B) is an essential micronutrient of mustard and play a vital role on its normal growth, and development. A study was conducted at (AEZ-20) Shiberbazar, Sylhet during November 2016-February 2017, to quantify the effect of boron on yield and yield attributes of mustard (BARI Sarisha-14), and different doses and form of B application. Randomized Complete Block Design (RCBD) was followed with three replications to design the study. Five B (boric acid) levels viz. T1 = basal application of B @ 2kg ha-1; T2 = foliar spray (FS) of B @ 0.5% at vegetative stage (VS) ; T3 = FS of B @ 1% at VS; T4 = FS of B @ 0.5% at VS + pod formation stage (PFS) and T5 = FS of B @ 1% at VS + PFS and T6 = control (no boron) were used. Results indicated that yield and yield attributes of mustard were significantly influenced by boron application. The effects of boron were significant on number of siliquae plant-1, number of seeds siliqua-1, seed yield, stover yield, 1000-seed weight, biological yield and harvest index (%). The highest number of siliquae plant-1 (35.93), number of seeds siliqua-1 (30.03), stover yield (1946.0 kg ha-1) and 1000-seed weight (3.617 g) were obtained from the treatment T5. The seed yield (801.17 kg ha-1) was found also in the treatment T5 which was over double than control (T6). Therefore, two times foliar application of B @1% at VS and PFS is a good option to increase yield and yield contributing characters of BARI Sarisha-14 in AEZ 20.

Storage pests of maize and their status in Bangladesh
Abstract
Maize (zea mays) is the most important cereal crop after rice in Bangladesh. During storage, maize grains are severely destroyed by insect pests. Most of the farmers of Bangladesh do not know how to preserve corn seed properly due to insufficient knowledge of storage pest of maize. An experiment was conducted to assess the major pests associated with stored maize, the damage and losses they cause in Bangladesh during July to December 2017. Sixty (60) farmer’s farms from fifteen major maize growing districts of Bangladesh were assessed. Sixteen Arthropods, Fifteen Coleopterans, Five Lepidopterans and one Acarina were documented from the collected samples. Maize weevil (Sitophilus zeamais) followed by maize grain moth (Sitotroga cereallela), rice weevil (Sitophilus oryzae), flour beetle (Tribolium confusum) and Areca nut weevil (A. fasciculatus) were the major pests of stored maize in the study area. Among them, Maize weevil (S. zeamais) is the dominant, destructive and most important pest of maize in Bangladesh. This pest was found in abundance in all areas assessed damaging maize grain. Quantitative average grain damage of 75.85% and losses of 51 to 85% are common in the store within five to six months after storage. An integrated weevil management method should be implemented to prevent the high quantitative and qualitative grain losses incurred to contribute towards family food security in Bangladesh.

Abstract
Maize (zea mays) is the most important cereal crop after rice in Bangladesh. During storage, maize grains are severely destroyed by insect pests. Most of the farmers of Bangladesh do not know how to preserve corn seed properly due to insufficient knowledge of storage pest of maize. An experiment was conducted to assess the major pests associated with stored maize, the damage and losses they cause in Bangladesh during July to December 2017. Sixty (60) farmer’s farms from fifteen major maize growing districts of Bangladesh were assessed. Sixteen Arthropods, Fifteen Coleopterans, Five Lepidopterans and one Acarina were documented from the collected samples. Maize weevil (Sitophilus zeamais) followed by maize grain moth (Sitotroga cereallela), rice weevil (Sitophilus oryzae), flour beetle (Tribolium confusum) and Areca nut weevil (A. fasciculatus) were the major pests of stored maize in the study area. Among them, Maize weevil (S. zeamais) is the dominant, destructive and most important pest of maize in Bangladesh. This pest was found in abundance in all areas assessed damaging maize grain. Quantitative average grain damage of 75.85% and losses of 51 to 85% are common in the store within five to six months after storage. An integrated weevil management method should be implemented to prevent the high quantitative and qualitative grain losses incurred to contribute towards family food security in Bangladesh.
