Abstract
The present investigation entitled “Effect of crop combination and nutrient management on field bean based intercropping system in vertisols” was carriedout at new orchard, Main Agricultural Research Station, UAS, Raichur, Karnataka, during the year 2018-19. The experiment was laid out in split plot design consisted of main plot treatments field bean alone as sole crop and amaranthus, radish, palak, coriander and fenugreek as intercrops whereas, sub plot consisted of FYM and fertilizer alone. Sole crop of field bean followed by field bean + amaranthus and application of FYM alone recorded the highest performance for all growth, yield attributes, yield and NPK uptake. The higher nitrogen availability in soil after harvest was observed in field bean + fenugreek and potassium was observed in field bean + amaranthus intercropping. The highest equivalent yield, net returns and B: C ratio was recorded in field bean + palak with the application of FYM alone. The study revealed that inclusion of palak, fenugreek and amaranthus as intercrop with field bean with the application of FYM alone gives higher growth, yield and nutrient availability. Whereas inclusion of palak as intercrop with field bean with the application of FYM alone gives higher returns per unit area
