Description Grain legumes such as chickpea, pigeonpea, cowpea, field pea , lentil, ,
and Phaseolus beans are the principal source of dietary protein among vegetarians,
and are an integral part of daily diet in several forms worldwide. They are an
important component of cropping systems to maintain soil fertility because of
their ability to fix atmospheric nitrogen, extract water and nutrients from the
deeper layers of the soil as compared to cereals, and add organic matter into the
soil through leaf drop. However, grain legumes are mainly grown under rainfed
conditions and the productivity levels are quite low mainly because of severe
losses due to insect pests and diseases. Average grain yield of pulses (0.86 t/
ha) is only about onefourth
the average yields of cereals (3.54 t/ha). Production
and productivity of grain legumes is constrained by several biotic and abiotic
factors, and suffer an average of 31.9 to 69.6% loss in crop productivity due to
insects, diseases, drought, weeds, and soil fertility. Pod borers (Helicoverpa
and Maruca), Fusarium wilts, viral diseases, Ascochyta blight and Botrytis gray
mold (Chen et al., 2011)...
