Abstract
A field experiment was conducted at All India Co-ordinated Research Project for Dryland Agriculture, UAS, GKVK, Bengaluru during Kharif 2013. Among different treatments, application of FYM at 10 t ha-1 has recorded significantly higher grain yield, net returns and B:C (1761 kg ha-1, Rs.21280 ha-1and 2.18) compared to application of maize residues at 5 t ha-1 (1365 kg ha-1 Rs. 11,528ha-1 and 1.52). Among two rotations, finger millet-groundnut rotation has given significantly higher grain yield, net returns and B:C (1783 kg ha-1 Rs. 21,150 ha-1 and 2.11) over mono cropping of finger millet (1343 kg ha-1 Rs. 11,658 ha-1 and 1.59 respectively). Among different nutrient sources, application of organic matter with 100 % RDF has given significantly higher grain yield, net returns and B:C (2741 kg ha-1 Rs. 36,934 ha-1 and 2.75 respectively) compared to absolute control (277 kg ha-1 Rs. -5212 ha-1 and 0.48 respectively).
