Abstract
“Studies on yield and income maximisation in tree mulberry based legume intercropping system” was carried out during 2020-2021 at KVK, V.C. Farm, Mandya. The results revealed that, higher soil pH (7.51) and EC (0.15 dS m-1) were recorded in sole tree
mulberry. Higher organic carbon (0.72 %), available nitrogen, phosphorous, potassium (377.15, 66.17 and 232.06 kg ha-1
, respectively), plant height (261.13 cm), shoot length (170.20 cm), number of shoots plant-1(23.80), number of leaves plant-1
(367.80), leaf yield (71.90 t ha-1year-1), leaf moisture content (75.09 %), moisture retention capacity (83.50 %), total chlorophyll (1.74 mg/g), leaf nitrogen (3.48 %), phosphorous (0.36 %) and potassium (2.14 %) contents were recorded in tree mulberry and black gram intercropping. Significantly maximum larval weight (38.65 g/10 larvae), cocoon weight (25.28 g/10cocoons), pupal weight (19.34 g/10 pupae), shell weight (5.85 g/10 shells), cocoon shell ratio (23.14 %), single cocoon filament length (1268.27 m) and denier (3.47) were observed in FC1 ⅹ FC2 double hybrid silkworm fed with tree mulberry leaves raised with black
gram. The least incidence of white muscardine (0.67 %) was observed in tree mulberry intercropped with black gram. Among the intercrops, higher number of pods (90.40) and seed yield (812.12 kg ha-1) were recorded in horse gram and cowpea, respectively. Black gram mulched tree mulberry plot recorded higher growth, yield, quality and rearing performance of silkworms. Maximum net returns (Rs. 3,31,204 ha-1) and B:C ratio (4.68) was recorded in tree mulberry and black gram intercropping.
