Field investigation was carried out during <italic>kharif</italic> season of 2012 the results showed that unchecked weeds caused a reduction of 66.67% in black gram yield. Two hand weeding at 25 and 50 DAS recorded maximum number of pods /plant, number of seeds /pod, 1000 seeds weight, seed yield and higher weed control efficiency followed by Imazathapyr+Imazamox (premix) @ 50 g/ha PoE at 20 DAS. Imazathapyr+Imazamox (premix) @ 50 g/ha at PoE 20 DAS registered highest net return and B:C ratio followed by Imazathapyr +Pendimethalin (premix) @ 1000 g/ha PE.

A field experiment was conducted during the rainy (kharif) season of 2013 and 2014 to find out the effect of “influence of mulching practices, varieties and fertility levels on growth and productivity of clusterbean ,,.The results revealed that the plastic mulch significantly increased the growth and yield characterstics, seed yield as well as economics over the weed biomass mulch and no mulch. Variety HG-563 recorded significantly higher growth characterstics, yield attributing, seed yield and economics as compared to RGC-1055. Among the fertility levels, application of 75% RDF + VC 5 t/ha resulted in significantly higher growth characterstics, yield attributing, seed yield and economics over all the remaining fertility levels. Thus, it can be concluded that in clusterbean (variety HG-563), adoption of plastic mulch along with RDF 75%+ 5 t/ha vermicompost is recommended for erratic and scarce rainfall as well as low sustainability of soil.

A filed experiment was conducted at College of Agriculture Farm, Gwalior on sandy clay loam soil during Kharif-2012 and 2013 to study the influence of nutrient management practices in pigeonpea and clusterbean intercropping system. On the basis of two year pooled data, results revealed that sole pigeonpea and clusterbean recorded significantly higher seed and stalk yield, harvest index, number of pods/plant, test weight, protein content, protein yield, dry matter/plant. Among the intercropping treatments T 4 (125% RDF to pigeonpea and no fertilizers to clusterbean) recorded significantly higher seed yield, stalk yield, harvest index, protein content, protein yield, yield attributes, pigeonpea equivalent yield and net return over other treatments except T 3 and T 5 which were onpar with T 4 treatment.
