  A field experiment with 10 treatments was conducted to evaluate the comparative efficacy of five chemicals viz., Streptomycin sulphate, Thiovit 80 WP, Sulfuric acid, Dithane M-45 and Cupravit either alone or in combination in controlling bacterial blight and on yield of cotton. Germination was highest in T10 i.e. Seed treatment with Streptomycin sulphate (0.15%) and foliar spray with Cupravit (0.2%) + Streptomycin sulphate (150 ppm) having 86.31 %. The lowest disease index (21.24%) was found in T10 subsequently after three foliar sprays at 104 DAS. This treatment reduced the disease intensity and increased the yield of seed cotton with 26.02%. The treatment T9 (Foliar spray with Cupravit + Streptomycin sulphate) also resulted better performance in reducing disease intensity and increased yield of seed cotton by 22.81%.

  Different post-harvest treatments manifested specific attribute in maintaining physical appearance, acceptability and economic return for cauliflower. It was observed that storage in perforated polythene bag prolonged the shelf life and helped maintaining highest physical appearance, acceptability and economic return of cauliflower. Considering weight loss and economic return, the wet gunny bag treatment was also found to be acceptable. Cauliflower showed the best physical appearance, acceptability, lower weight loss and thereby rendered the highest economic return with perforated polythene bag treatment at 4 days after storage (DAS). In this case wet gunny bag was also found to be acceptable considering as physical appearance, acceptability grade and net economic return.

  Twenty nine different genotypes/advanced breeding lines and four cultivars/checks viz., BR 11, BR 22, BR 25 and BRRI dhan 38 of rice were selected for the study to examine and screen out the advanced hybrid lines, which are resistant/tolerant to brown spot and blast disease. One accession showed resistant (R) reaction in T. aman season and twenty-nine cultivars showed moderately resistant (MR) reaction in boro season to brown spot. Thirteen accessions were found as moderately resistant (MR) in T. aman season and three breeding lines/genotypes were found to be highly resistant (HR) and five were resistant (R) in boro season to blast. So, these lines/cultivars may be used as breeding materials and cultivated for rice production.

  The incidence of leaf spot of mustard (cv. BARI sharisha 13) grown in different orientations and distances under around twelve years old Akashmoni (Acacia auriculiformis) tree was studied in the field laboratory of the Department of Agroforestry, BAU, Mymensingh during 2004-05. The assessment result showed that the disease incidence was higher near the tree base in every side (1 m from the tree base) and higher in North side in all distances at different date of sowing. The lowest disease incidences were found in South orientations 3 m from the tree base and highest in North 1 m from the tree base. The siliqua infection significantly influenced on crop yield. The highest seed yield was observed in South orientation 3 m from the tree base and lowest in North 1 m from the tree base plot. The distance and orientation showed marked effect in disease development at different date after sowing. In open field condition (control) disease incidence also affect on yield and statistically different from tree-crop combination.

  Different post-harvest treatments manifested specific attribute in maintaining physical appearance, acceptability and economic return for brinjal. It was observed that wet gunny bag treatment also resulted in the best physical appearance, acceptability, reduced weight loss and thereby highest economic return for brinjal at four days after storage. Considering all the attributes, perforated polythene bag treatment was also found to be a suggestive treatment for better storage.

  Twenty nine different genotypes/advanced breeding lines and four cultivars/checks viz. BR11, BR22, BR25 and BRRI dhan 38 of rice were selected for the study to examine and screen out the advanced hybrid lines, which are resistant/tolerant to BLB and sheath rot. Three accessions (22, 68, 157) showed resistant reaction in T. aman season and six accession (22, 54, 58, 68, 139, 157) showed highly resistant (HR) reaction and four entries (37, 62, 75, 128) were resistant to BLB in Boro season. One accession (58) showed resistant in T. aman season and three (59, BR11, BRRI dhan 38) were found highly resistant and one accession (54) showed resistant reaction to sheath rot in Boro season. So, these lines/varieties may be used as breeding material and cultivated for rice production.

  Different post-harvest treatments manifested specific attribute in maintaining physical appearance, acceptability and economic return for bitter gourd. The physical appearance of bitter gourd at 6 days after storage was better in the perforated polythene bag and wet gunny bag. At the harvesting stage (0 day of storage) the score was the highest 10 and at 6 DAS the highest score 6 and 7 were recorded in perforated polythene bag and wet gunny bag, respectively. The gross return after 4 days after storage was higher in these treatments.

  An experiment was conducted to study, the effect of different planting date and variety on the extension of picking period of tomato at the Horticulture Farm, BAU, Mymensingh during 2000-2001. Yield and yield contributing characters were best in October 25 planting . The highest yield of tomato (86.40 t ha-1) was obtained from October 25 planting, compared to the lowest ( 16.8 t ha-1) from February 24 planting. The variety BARI Tomato 7 produced the highest yield (57.02 t ha-1) and BARI Tomato 5 produced the lowest yield (51.38 t ha-1). All the parameters showed decreasing response with delay in planting.

  Mixed inocula of Meloidogyne javanica and Sclerotium rolfsii in five different treatments including control were tested for the growth, yield, galling incidence and development of the nematode in groundnut. Progressively higher galling incidence and higher number of adult females and juvenile populations of M. javanica correspondingly with lower plant growth, nodulation and yield per plant were recorded from lower to higher levels of inocula ranging from 4-10 egg masses of M. javanica with 0.025 - 0.2% w/w of S. rolfsii . Galling incidence was negatively correlated with plant growth, nodulation and yield of groundnut.

  The effects of different levels of nitrogen and boron fertilizer were determined on the yield and yield components of winter Chilli (Capsicum annum L) using different levels of nitrogen viz., 0, 20, 40, 60, 80, 100, 120 and 140 kg ha-1 and three levels of boron viz., 0, 1.5, 2.5 kg ha-1. The highest chilli yield (dry) was obtained from 120 kg N ha-1 (2.41 ton ha-1 in 1997-98 and 2.77 ton ha-1 in 1998-99) which differed significantly from other nitrogen levels. The yield was progressively increased with the increased levels of nitrogen up to 120 kg N ha-1 and there after it was declined. Among different levels of boron, the highest yield was obtained from 2.5 kg B ha-1 which was identical to 1.5 kg B ha-1. Interaction effects between nitrogen and boron on the chilli yield were found significant. In both the years, the highest chilli yield was recorded from 120 kg N ha-1 when applied with 2.5 kg B ha-1 which was identical to 120 kg N ha-1 when applied with 1.5 kg B ha-1.

  The experiment was conducted to know the effect of seed treatment on the incidence of seed-borne fungal diseases and on production of seed yield of okra. The lowest germination (95.0%) was recorded in unclean farmer’s seeds; while highest germination (99.0%) was recorded in Vitavax-200 treated seeds followed by clean apparently healthy seeds (98.5%). Seed-borne fungal diseases of okra in the field, five diseases viz. Foot and root rot, Anthracnose and die-back, Cercospora leaf spot, Corynespora leaf spot and leaf blight, respectively caused by Fusarium oxysporum, Colletotrichum dematium, Cercospora abelmoschi, Corynespora cassiicola and Macrophonina phaseolina were recorded. The incidence of five seed-borne diseases have been found to be reduced by the use of seeds treated with Vitavax-200 and clean apparently healthy seeds. Vitavax–200 treated seeds as well as clean apparently healthy seeds increased the seed yield by 21.62 and 15.31%, respectively, over the unclean farmers’ seeds.

  Market diseases of banana were surveyed in three markets of Mymensingh town. Anthracnose and botryodiplodia rots were detected as the main cause of market rots of banana fruits. About 2.04-4.90% fruits were rotted during April-September due to anthracnose and 2.96-4.74% owing to botryodiplodia rots. Both the diseases clearly correlated positive with temperature. The causes of anthracnose and botryodiplodia rots were identified as Colletotrichum musae and Botryodiplodia theobromae, respectively.
