EFFECT OF NITROGEN AND SULPHUR ON GROWTH AND YIELD OF BLACK GRAM ISLAM, MD. SHADEKUL The experiment was conducted at experimental plot of Agronomy farm of Sher-eBangla Agricultural University, Dhaka with a view to finding out the optimum dose of Nitrogen and Sulphur for maximizing the growth and yield of Black gram and their interactions on of Nitrogen and Sulphur fertilization for proper growth and yield of Black gram. The experiment consisted of treatment N 0 (no nitrogen) N (nitrogen @ 10 kg ha -1 ) N 2 (nitrogen @ 20 kg ha -1 ) N 3 (nitrogen @ 30 kg ha -1 ) and S (no sulphur), S 1 (sulphur @ 5 kg ha -1 ), S 2 (sulphur @ 10 kg ha -1 ). The experiment was laid out in a two factor randomized complete block design with three replications. Growth characters, yield contributing characters and yield of blackgram were significantly influenced by nitrogen, sulphur and their interaction. At vegetative growth stage, application of nitrogen @ 30 kg ha -1 combined with sulphur @ 10 kg ha produced the highest plant height (34.00 cm), number of leaves plant -1 (28.28), dry matter weight (23.12 g) and number of branches plant -1 (6.15) at harvest. The highest number of pods plant -1 (64.80), number of seeds pod -1 (5.46), pod length (4.52 cm), 1000-seed weight (36.49 g), seed yield (1.68 t ha -1 ), stover yield (2.03 t ha -1 ), biological yield (3.71 t ha -1 ) and harvest index (45.39 %) were found in nitrogen @ 10 kg ha . The highest seed yield (1.68 t ha -1 ) was obtained in nitrogen @ 30 kg ha and the lowest seed yield (.81 t ha -1 ) was obtained in no nitrogen application. The application sulphur @ 10 kg ha -1 -1 showed superiority in terms of the highest number of pods plant (54.75), number of seeds pod -1 (5.13), pod length (4.05 cm), 1000-seed weight (33.87 g), seed yield (1.40 t ha -1 ), stover yield (1.80 t ha -1 1 0 ), biological yield (3.20 t ha ) and harvest index (43.51 %). In case of interaction, the highest seed yield (1.81 t ha ) was recorded in nitrogen @ 30 kg ha -1 when combined with sulphur @ 10 kg ha . It can be concluded that the nitrogen @ 30 kg ha -1 appears to be promising fertilizer in terms of seed yield when combined with sulphur @ 10 kg ha -1 .

EFFECT OF BIOCHAR ON GROWTH AND YIELD OF MUNGBEAN ( BARIMung-6 ) TOMA, KAMRUNNAHER This research work was conducted at Sher-e-Bangla Agricultural University Farm, Dhaka during the period from March, 2017 to July, 2017 to study the growth and yield of mungbean (BARI Mung-6) as influenced by different levels of biochar. The experiment comprised of the following 8 treatments as T 1 = Control,T 2 = RFD (Recommended Fertilizer Dose);T = RFD + Biochar @ 2 ton ha -1 T 4 = RFD + Biochar @ 4 ton ha ii -1 ;T 5 3 = ⅔of RFD + Biochar @ 2 tonha -1 ; T 6 = ⅔ of RFD + Biochar @ 4 ton ha -1 ; T = ½ of RFD + Biochar @ 2 ton ha -1 ;T 8 = ½ of RFD + Biochar @ 4 ton ha -1 7 . The experiment was laid out in a Randomized Complete Block Design (RCBD) with three replications. From the research field, the maximum plant height (44.70 cm) was recorded from T treatment, which was statistically identical with other treatments whereas, the minimum plant height (37.57 cm) was recorded from T treatment. The maximum number of branches plant-1, number of pods plant 1 , pod length (cm), number of seeds pod -1 -1 , weight of l000-seed (g) was recorded from T treatment, which was statistically identical with other treatments whereas, the minimum plant height was recorded from T treatment. In addition, yield of grain ton per ha significantly varied among the different levels of biochar applications (Table 4).On the one hand the highest grain yield (1.40 t ha 1 ) was obtained from T 3 (RFD + Biochar @ 2 ton ha -1 ) treatment, which was followed by T 4 (1.29 t ha -1 ) and lowest grain yield (0.83 t ha -1 -1 ) was obtained from T (control) treatment. On the other hand, in all the cases lower values were found in the control treatment. From this study, it may be concluded that biochar had significant positive effect on growth and yield of mungbean. DEPARTMENT OF SOIL SCIENCE SHER-E-BANGLA AGRICULTURAL UNIVERSITY DHAKA-1207

RESPONSE OF MUNGBEAN TO ZINC, BORON AND MOLYBDENUM APPLICATION NAHAR, NAZMUN A field experiment was conducted at Sher-e-Bangla Agricultural University Farm, Dhaka during the period from April 2017 to July 2017 to study the response of mungbean (BARIMung-6) to zinc, boron and molybdenum application.The single factor experiment was consisted with eight treatments viz., T 1 = Control, T 2 = Zn 2.0 kg ha -1 , T 3 = B 1.5 kg ha -1 , T 4 = Mo 1.0 kg ha = Zn+B, T 6 = Zn+Mo, T 7 = B+Mo and T = Zn+B+Mo.The experiment was laid out in Randomized Complete Block Design (RCBD) with three replications. Results showed that plant height, number of branches plant -1 8 , pod length, number of pods plant -1 , number of seeds pod , grain yield, stover yield, biological yield, harvest index and available phosphorous and exchangeable potassium content of post-harvest soil was significantly influenced by zinc, boron and molybdenum application.Among the different treatments T (2kg Zn+1.5 kg B+1 kg Mo) treatment produced tallest plant (44.40 cm), highest number of branches plant 8 (9.5), maximum number of pods plant -1 (13.0), maximum length of pod (9.60 cm), maximum number of seeds pod -1 (10.00), highest 1000 grain weight (50.80g), highest grain yield (1.40 t ha ) and maximum harvest index (52.84%).This combination also exhibited highest pH (6.05), organic matter (1.39 %), total nitrogen (0.092%), available phosphorous (23.45 ppm) and exchangeable potassium content (0.24 meq/ 100 gm soil) of post-harvest soil. On the other hand, T (Control) treatment produced lower values in all cases except stover yield and harvest index. From the growth, yield and post-harvest soil analytical reports, it is apparent that the combination of 2kg Zn+1.5 kg B+1 kg Mo (T8) was suitable for mungbean cultivation DEPARTMENT OF SOIL SCIENCE SHER-E –BANGLA AGRICULTURALUNIVERSITY DHAKA-1207

COMPARATIVE STUDY OF USG AND NPK BRIQUETTE ON THE PERFORMANCE OF AROMATIC RICE VARIETY BRRI dhan70 AKTAR, MST. SHAMIMA The experiment was conducted in the farm area of Sher-e-Bangla Agricultural University, Sher-e-Bangla Nagar, Dhaka during the period of July to November, 2017 for comparative study of USG (urea super granule) and NPK briquette on the performance of aromatic rice variety BRRI dhan70. In this experiment BRRI dhan70 aromatic rice were used as the test crop. The experiment comprised of the treatments of T 0 PKSZn, T 3 : Control, T 1 : 100% RFD, T 2 : 80% RFD + 2 USG within 4 hills, T 4 ii : 1 USG (1.8 g) within 4 hills + : 1 NPK briquette within 4 hills, T 5 : 2 NPK briquette within 4 hills and T 6 : 80% RFD + 1 NPK briquette within 4 hills. The experiment was laid out in Randomized Complete Block Design (RCBD) with three replications. Data were recorded on different yield contributing characters, yield and characteristics of post-harvest soil and statistically significant variation was recorded for most of the studied characters. The tallest plant (134.47 cm), maximum number of total tillers hill (19.07), maximum number of total grains panicle -1 (145.20), the longest panicle (28.75 cm), highest grain yield (4.83 t ha -1 ) and highest straw yield -1 (6.26 t ha ) was recorded from T 6 treatment, while the shortest plant (106.17 cm), minimum number of total tillers hill -1 (15.00), the shortest panicle (22.88 cm), minimum number of total grains panicle -1 (120.47), lowest grain yield (2.88 t ha ) and lowest straw yield (4.40 t ha (0.064%), highest available P -1 )was found in T 0 -1 -1 treatment. The highest total N (32.23 ppm) and highest exchangeable K (0.178 meq/100 g soil) was recorded in T 6 treatment, while the lowest total N (0.032%), lowest available P (17.29 ppm) and lowest exchangeable K (0.081 meq/100 g soil) was found in T 0 . Application of 80% RFD + 1 NPK briquette within 4 hills was the package of nutrient for achieving higher yield of aromatic rice (variety BRRI dhan70) at Tejgaon series soil of SAU farm.
