Nitrogen Level and Physiological Basis of Yield of Mungbean at Varying Plant Population in High Ganges River Flood Plain Soil of Bangladesh

M.A.K. Mian and J. Hossain

Abstract:
A field experiment was conducted at the Regional Agricultural Research Station of Bangladesh Agricultural Research Institute, Jessore during early kharif season of 2009 and 2010 to observe the effect of nitrogen on the physiological basis of yield of mungbean at varying plant population. In the experiment, four nitrogen levels (N0, N40, N60 and N80 kg ha-1) were assigned in the main plots and three plant population (P30, P35 and P40 m-2) in the sub plots. The results revealed that mungbean showed better growth in N60 and N80 kg ha-1 representing higher values of CGR, TDM, LAI and plant height while N40 exhibited intermediate growth. Again, growth of mungbean was better in higher plant population (35-40 m-2) representing higher values of growth parameters. Seed yield of mungbean was obtained the highest (1908 kg ha-1) associated with the highest No. of pods plant-1 (29.98), seeds pod-1 (10.41) and 1000-seed weight (37.70 g) in N40 kg ha-1. Further, seed yield of mungbean was the highest (1919 kg ha-1) in plant population of 40 m-2. In interaction, seed yield was the highest (1963 kg ha-1) in N40 kg ha-1 with plant population of 40 m-2. The effect of applied nitrogen on the seed yield of mungbean can be explained 78% (R2 = 0.78) by this function (Y = 1540.70+16.069x-0.173x2). The optimum nitrogen level was 46 kg ha-1 by using the developed functional model and then the predicted seed yield of mungbean would be 1944 kg ha-1.
