POTASSIUM BALANCE IN SOIL AS AFFECTED BY INTERCROPPING IN WHEAT (Pages : 16 - 21)

A field experiment was conducted during November 2009 to April 2010 on intercropping of soybean, potato, lentil, mustard, cowpea, linseed and coriander with wheat crop at the Agronomy Field Laboratory, Bangladesh Agricultural University, Mymensingh to evaluate the soil potassium balance of different intercrop combinations compared to their respective sole cropping. The experiment was laid out in a randomized complete block design with seven intercrops and eight sole crops treatment combinations assigned in three replications. Depending on the yield level total K uptake ranged from 46.20 to 89.84 kg ha-1 in wheat sole and intercropping treatments. The balance of potassium was negative in wheat sole and all intercropping patterns. The highest negative balance of potassium was found (-13.24 kg ha-1 ) in wheat + potato and the lowest negative value was found (-1.21 kg ha-1 ) in wheat + lentil. The highest and lowest positive balances of potassium were found in potato sole (+29.32) and mustard sole (+ 0.24 kg ha-1 ), respectively. Download
