The experiment was laid out in a Randomized Complete Block Design (RCBD) with three replications of each treatment. The unit plot size was 2.4 m2 ( 1.6 m x 1.5 m). There were 12 treaunent combinations in the experiment comprising 4 levels of N (0. 30, 60 and 90 kg/ha designated as N0• N3o. N60 and N90. respectively) and 3 levels of P (0, 50 and 75 kg P205/ha designated as P0, P50 & P15, respectively). The individual and combined effects of nitrogen (N) and phosphorus (P) on growth and yield of garden pea were studied. The individual and interaction effects of N and P on growth and yield was found significant. Nitrogen@ 90 kg/ha gave the highest plant height, root length, highest number of branches per plant. highest pod length. highest number of seed per pods, 1000-seed weight, highest green pod yield and seed yield per hectare. The highest plant height, highest root length, highest green pod yield was recorded in 75 kg P205/ha. Phosphorus @ 50 kg/ha gave the highest number of branches per plant. highest length of pods and seed yield per hectare. The treatment combination of NooPso produced the maximum plant height. root length. highest green pod yield and highest seed yield per hectare but the treatment combination of N90 P75 gave the maximum plant height at vegetative stage. highest number of pods per plant, highest length of pod and maximum N, P, K and S content in plants. Lowest N, P, Kand S contents were found in control (N0P0) treatment. From the present findings it can be concluded that combined application of N @ 90 kg/ha and P @ 50 kg/ha is the most suitable combination to achieve the maximum return from garden pea plants.Item PERFORMANCE OF NEEM-COATED UREA OVER NORMAL UREA ON THE GROWTH AND YIELD OF BARI-BUSH BEAN-l(DEPARTMENT OF SOIL SCIENCE, SHER-E-BANGLA AGRICULTURAL UNIVERSITY, DHAKA, 2009-12) ADIOKARI, CHINMAYEEThe experiment was conducted in the field of Sher-e-Bangla Agricultural University Farm, Dhaka, Bangladesh during the period from October, 2008 to March, 2009 to find out the performance of Neem-coated urea over normal urea on the growth and yield of BAR!

The experiment was laid out in a Randomized Complete Block Design (RCBD) with three replications of each fertilizers treatment combination. The treatments used were: four levels of nitrogen as No: 0 kg N/ha, N 100: 100 kg t N/ha. N150 : 150 kg N/ha and N 200 : 200 kg N/ha and four levels of phosphorous as P0: 0 kg P 205/ha, P50: 50 kg P 205Tha, P 100: lOU kg P 205!ha and p150: 150 kg P 205 /ha with 16 treatment combinations. Yield and yield contributing characters, N and P concentration in plant and post harvest soil were recorded. Plant height at 60 days after transplanting, number of branches per plant, number of flowers per plant, number of fruits of plant and fruit weight per plant increased significantly with increasing N level up to 150 kg N/ha, whereas fruit yield increased significantly up to 200 kg N/ha. All these parameters also increased significantly with increasing the level of P up to 150 kg P/ha. However, the treatment showed the maximum plant height at harvest (93.62 cm). On the other hand, the treatment combination N20oPI00 produced the maximum combination N 200? ISO number of flowers per plant (49.86), number of fruits per cluster (3.99), number of fruits per plant (38.30) fruit weight (2.5 kg/plant) and fruit yield (89.93 tlha). N and P concentrations in shoot and fruit were the highest in N 200P150 treatment. The treatment had no significant effect on pH of post harvest soil. However increasing the application of nitrogen increased soil total N and P content up to N 150 treatment. Application of P had not significant effect on total nitrogen but P 150 produced the highest P content in soil. N 200?150 combination had the highest N (0.119%) and P (44.77 ppm) concentration in plant.Item INFLUENCE OF PHOSPHORUS FERTILIZATION ON DIFFERENT HYBRID MAIZE VARIETIES(Department of Soil Science, 2009-12) Ahmmed, Md. BnlbulA field experiment was conducted at the central research farm of Bangladesh Agricukural Research Institute, Gazipur during the period from November 2008 to April 2009 to investigate the effect of different levels of phosphorus application on growth, yield attributes and yield of hybrid maize. The soil belongs to the Chhiata soil series under AEZ-28 (Madhupur Tract). The soil is clay loam having pH 6.20, organic carbon 0.99%, total nitrogen 0.052%, available phosphorus 13.1 ppm, exchangeable potassium 0.39 me/100 g soil and available sulphur 8.51 ppm. The experiment comprised four hybrid maize varieties viz., BARI hybrid maize-i. BARI hybrid maize-3. BARI hybrid maize-5 and BARI hybrid maize-7 and four levels of phosphorus viz. 0, 30. 60 and 90 kg ha' along with a blanket dose of N 250K,00S40Mg,0 7,n 5 B 2 kg hi1 and cowdung 5 t hi'. Phosphorus was used as triple super phosphate. The experiment was laid out in two factors randomized complete block design with three replications. Phosphorus significantly increased morphological, yield attributes and grain yield of maize up to 60 kg P hi' and at the highest level of application, yield was declined. The highest grain yield (7.62 t hi') was observed at 60 kg P hi' treatment. Phosphorus increased the grain yield by 2 1.7-54.3% over the control. BARI hybrid maize-7 showed the highest grain yield (6.81 t hi'). !-lowever, from regression analysis, the optimum dose of phosphorus was found to be 73, 86, 70 and 78 kg hi' for BARI hybrid maize-2, BARI hybrid maize- 3, BARI hybrid maize-5 and BARI hybrid maize-7, respectively for maximizing the yield of maize. The P uptake increased with increasing rate of P application in all the four tested varieties. Phosphorus showed a positive balance in all treatments in the study area for hybrid maize production. Considering the economic returns, phosphorus P. 60 kg hi' kg hi' and cowdung 5 t hi' appeared to be the best-suited dose which may be recommended for maximizing the yield of hybrid maize in the AEZ-28.Item EFFECT OF NITROGEN AND POTASSIUM ON THE GROWTH AND YIELD OF BARI BUSH BEAN-2(Phaseolus vu/garth)(Department of Soil Science, 2009-12) ROY, `BASUDEBA field experiment was earned out at Sher-e-I3angla Agricultural University Farm during the Rahi season ol' 2008 to investigate the efThet of nitrogen and potassium on the growth and yield of F3ARI [lush Bean-2.
