Abstract:
Field experiment was carried out at Research Farm, Indira Gandhi Krishi Viswavidyalaya, Raipur (Chhattisgarh) during Rabi seasons of 2013-14 and 2014-15 to study the effect of nutrient management and weed management practices on yield and nutrient status. The highest crop stand was under 100% RDF
i.e. 17.35 and 18.1 during 2013-14 and 2014-15, respectively with mean of 17.73 and in untreated control
i.e. 18.48 and 18.81 during 2013-14 and 2014-15, respectively with mean of 18.65.The maximum number of nodules and nodule dry weight were obtained under 100% RDF. Pre-emergence application of metribuzin 0.4 kg ha
-1 + oxyfluorfen 0.3 kg ha
-1produced the maximum number of nodules and nodule dry weight. Application of 125% RDF gave the maximum net returns (

The maximum energy intensiveness (2.07 and 2.20 during 2013-14 and 2014-15, respectively with mean of 2.13) was under application of 125% RDF. Amongst the weed management practices, the maximum energy intensiveness (2.39 and 2.45 during 2013-14 and 2014-15, respectively with mean of 2.42) was under pre-emergence application of metribuzin 0.4 kg ha
