Response of spring mungbean (Vigna radiata L.) to nutrient management in Western U.P.

Abstract

A field experiment was conducted at Crop Research Centre of Sardar Vallabhbhai Patel University of Agriculture & Technology, Meerut, during spring season of 2015. The ten treatments viz. control, N (18 kg/ha), NP (18:46 kg/ha), NPK (18:45:30 kg/ha), NPKS (18:45:30:20 kg/ha), NPK S Zn (18:45:30:20:20 kg/ha), NPK S Zn Fe (18:45:30:20:20:5 kg/ha), NPK S Zn Fe Rhizobium (18:45:30:20:20:5 kg/ha), NPKS Zn Fe PSB (18:45:30:20:20:5 kg/ha) and NPK S Zn Fe Rhizobium PSB (18:45:30:20:20:5 kg/ha) were tested in randomized block design with three replications. The experimental soil was sandy loam in texture, low in organic carbon and medium in available P and K. The SML-668 variety of moongbean was planted. Among all the treatment application of 18, 46, 30, 20, 20 and 5 kg ha-1 N P K S Zn Fe with Rhizobium and PSB received maximum plant height, number of green trifoliate leaves, dry matter accumulation, number of active nodules, number of pod plant-1, number of grain pod-1, straw and biological yield, which was significantly more than the other treatments. An increase of 381 and 64 percent over control and N P K respectively in grain yield were recorded due to nutrient management and also to be found significantly higher gross return, net return and increment in nutrient availability compare to control treatments.
