PERFORMANCE OF MUNGBEAN IN WHEAT-MUNGBEAN SYSTEM UNDER INTEGRATED PLANT NUTRIENT MANAGEMENT ON ERODED LANDS

Field experiments were conducted at three sites in Malakand and Swat districts, North West Frontier Province (NWFP) of Pakistan to study the performance of mungbean (Vigna radiata L.) in wheat-mungbean cropping systems on eroded lands during 2004 and 2005. Wheat crop received three treatments (T1) 60-45-0-0, (T2) 120-90-60-5, and (T3) 60-90-60-5 kg N-P2O5- K2O-Zn ha-1. The third treatment received 20 t ha-1 farm-yard manure (FYM) one month before sowing of wheat. Wheat crop was followed by mungbean which received (T1) 0-45-0-0, (T2) 0-90-60-5 and (T3)0-90-60-5 kg N-P2O5- K2O-Zn ha-1 in the respective treatments. The data showed that during 2004, T3 gave the highest mungbean yield of 516 kg ha-1 on average and was significantly different from the other treatments with an increase of about 61 % over T1 and 15 % over T2. With regards to sites, Matta had significantly higher yields than Kabal and Thana. During summer 2005, similar results were observed with the highest yield of 1218 kg ha-1 from T3 with an increase of about 103 % over T1 and 23 % over T2. The Thana site had significantly higher yields than Kabal and Matta during 2005. The yields were significantly higher during summer 2005 than 2004.This was due to the carryover effect of nutrients and mungbean straw during 2005
