PAUL, PORITOSH CHANDRA A pol experiment was conducted at the Net I rouse and J .uboratory of Soil Science Div ision, Bangladesh Agricultural Research Institute (BARI), Joydebpur, Gazipur during September Lo I >ecember 2007 to study the effect of nitrogen, molybdenum. boron and Bradyrhizobium inoculant on growth, nodulation, ) icld. yield contributing characters. nitrogen uptake of black gram. I he variety. BARI Mash-J and Bradv rhizobium inoculant {liARJ RVm-301) were used in the present experiment. I here were twelve treatment combinations viz.

Nitrogen@ 50 kg N ha-1~ triple super phosphate@ 22 kg P ha-•. muriate of potash (@ 42 kg K ha", boron @ I kg B ha"1 and rnoly bdcnum @ I kg rvto ha" were applied as per treatments of the experiment as recommended levels. Gypsum@ 20 kg Sha-• and zinc sulphate@ 5 kg ha" were applied as basal in all pots except in control pot. After 30~ 45 and 60 day s of sowing, 2 plan ls were uprooted from each pot to study nodulation, dry matter production and plant growth. Al maturity, ) ield and ) ield contributing characters "ere recorded. Bradyrhizobium inoculation increased significantly the number of nodules. nodule weight. root and shoot length. seed and stover) icld, yield attributes. nitrogen and protein content of blackgram compared to non-inoculated control. Brady rhizobium inoculation in presence of Mo and B recorded the highest nodule number and nodule weight. and also seed and stover ) icld. Bradyrhizobium inoculation alone or in presence of Mo or boron also recorded higher nodulation over other treatment combinations. Brady rhizobium inoculation was better than nitrogen in almost all the par- • ameters studied. Moly bdcnum and boron performed better results. ·y his result indicated that the use of Brudy rhizobium inoculants with molybdenum and boron appeared lo be an effective method for successful blackgram production.

UDDIN, BORHAN A field experiment was conducted at the research farm of Sher-e-Bangla Agricultural University, Dhaka during December 2007 to February 2008 to study the effects of different levels of nitrogen and phosphorus on the growth and yield of garden pea. 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.

Bush bean- 1. The experiment consisted of the treatments T o: No nitrogen, T1 : 40 kg N/ha, T 2: 80 kg N/ha, T3 : 120 kg N/ha, T 4: 160 kg N/ha, 1'5: 40 kg N/ha (supplied neem-coated urea), 1 4 : 80 kg N/ha (supplied neem-coated urea), T 7: 120 kg N/ha (supplied neem-coated urea) and T 3 : 160 kg N/ha(supplied neem-coated urea). The tallest plant (13.83 cm, 24.09 cm, 40.04 cm, 46.20 cm and 54.90 cm)at different days interval was recorded from T 7 , while at the same interval the shortest plant (10.27 cm, 19.35 cm, 31.15 cm, 35.66 cm and 44.20 cm) from T o. The maximum number of pods per plant (32.05) was obtained from T 7 , while the minimum number (21.03) from To. The highest pods yield (16.28 tlha) was observed from 1'7 , while the lowest yield (11.57 tlha) from T o. Use of neem-coated urea increased pod number per plant significantly at all levels compared to the respective normal urea treatments. However, in terms of pod yield (tlha) neem-coated urea at the rate of 120 kg N/ha only had significant favorable over normal urea at the same rate. Neem-coated urea failed to have any significant effect on plant height at 55 DAS. The maximum concentration of N (3.851 /o), p (1.5 1%), K (1.36%) and S (1.25%) in plant was recorded with T7 and the minimum concentrations of N (1.21%), P (0.36%), K (0.34%) and S (0.33%) in plant were observed from T. The maximum uptake by stover forN (41.52 kg/ha), P (6.34 kg/ha), K (14.15 kg/ha) and S (8.23 kg/ha) were recorded from T 7 , again the minimum uptake by stover for N (11.04 kg/ha), p (3.00 kg/ha), K (7.44 kg/ha) and S (4.33 kg/ha) were found from T o. The maximum uptake by pod for N (65.63 kg/ha), P (17.03 kg/ha), K (36.26 kg/ha) and S (3.18 kg/ha) were obtained from T 7 , while the minimum uptake by pod for N (10.21 kg/ha), P (10.16 kg/ha). K (21.69 kg/ha) and S (2.26 kg/ha) were observed from To . The highest p11 (5.57), organic matter (1.45 0 /6), total N (0.088%), available P (22.78 ppm), exchangeable K (0.18 me%) and available S (30 ppm) were found from T4 and the lowest p11 (4.06), organic matter (1.01%), total N (0.12 0/6), available P (13.75 ppm), exchangeable K (0.11 me%) and available S (0.17 ppm) were recorded from ...
