EFFECT OF WEED MANAGEMENT PRACTICES UNDER VARIOUS FERTILITY LEVELS ON YIELD, NITROGEN CONTENT AND PROTEIN OF SPRING MUNGBEAN

Gargi Goswami, Chandra Bhushan, Anil Shukla and Santosh Kumar

Abstract

A field experiment was conducted during spring season of 2012-13. The experiment consisted of four treatments of fertility levels in main plot (RDF, ½ RDF +2% urea spray, two sprays of 2% urea and control) and five treatments of weed management in subplot (pendimethalin @ 1kg/ha, imazethapyr @ 50 g/ha, chlorimuron-ethyl @ 4 g/ha, hand weeding and weedy check), thereby making twenty treatment combinations tested in split plot design with three replications. Results indicated that application of RDF significantly increased the number of pods, seed yield and biological yield over other fertility levels. Results further indicated that among weed management practices hand weeding resulted in increase in the number of pods, seed yield and biological yield which was followed by application of pendimethalin. The fertility levels significantly influenced the N content in straw and grains while the affect of the weed management practices was significant on N content in grains, only. However both the management practices influenced the protein content in grains significantly.
