    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, CHINMAYEE
    The 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! 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 ...
