EFFECT OF INTEGRATED WEED MANAGEMENT ON ECONOMICS OF SOYBEAN (GLYCINE MAX (L.) MERRILL) UNDER VERTISOLS OF CHHATIISGARH

摘要

Soybean is mainly grown during khanif season in Chhattisgarh. In monsoon season weed infestation is one of the major factors which limits productivity level of soybean crop. It is estimated that the loss in yield of soybean is 30 to 77 per cent due toimproper weed management (Chandei and Saxena, 1988). Manual weeding is one of the oldest and most efficient methods of weed control. But unavailability of adequate labourers, then increased wages and declining efficiency under uncongenial conditions (like continuous spell of monsoon) make the tasks more difficult. Under these circumstances, the information on integration of effective and workable weed management practices which can be used ecologically and economically by the farmers is necessary. Keeping in view these facts, the present investigation was under taken to study the effect of F YM and various weed management practices on the economics of soybean cultivation.
