Abstract
Field experiments were conducted at, UAS, Raichur farm, during kharif season of 2015-16 and 2016-17 to study production and nutritional quality enhancement of nutri-cereals through agronomic manipulations.
In an experiment with respect to performance of pigeonpea and nutri-cereals in intercropping systems, intercropping of pigeonpea with foxtail millet (1:1) (991 kg ha-1) recorded significantly higher seed yield of pigeonpea and was on par with pigeonpea + sorghum (1:1) (909 kg ha-1), pigeonpea + foxtail millet (1:2) (847 kg ha-1) and pigeonpea + pearl millet (813 kg ha-1). However, pigeonpea + sorghum (1:1) (1205 kg ha-1) and pigeonpea + foxtail millet (1:1) (1193 kg ha-1) recorded significantly higher pigeonpea equivalent yield and found at par with sole pigeonpea (1360 kg ha-1). Land equivalent ratio indicated yield advantage, to the extent of 28 to 45 per cent obtained due to intercropping with sorghum, foxtail millet and pearl millet. Sole pigeonpea recorded significantly higher net returns (56,507 Rs. ha-1) and BC ratio (3.33) over intercropping systems and was found on par with pigeopea + sorghum (1:1) (46,597 Rs. ha-1 and 2.74), respectively. The results of experiment on the performance of different nutri-cereals in strip cropping with pigeonpea under varied fertility levels indicated that pigeonpea + foxtail millet (2:4) with 100 % RDF to both component crops (1042 kg ha-1) recorded significantly higher pigeonpea equivalent yield and was found to be on par with pigeonpea + sorghum (2:4) with 100 % RDF to both component crops (1017 kg ha-1), pigeonpea + sorghum (2:4) with 50 % RDF through organic + 50 % RDF through inorganic to both component crops (1001 kg ha-1) and pigeonpea + foxtail millet (2:4) with 50 % RDF through organic + 50 % RDF through inorganic to both component crops (969 kg ha-1). However, pigeonpea + sorghum (2:4) with 100 per cent RDF to both component crops recorded significantly higher net returns and BC ratio (Rs.34,641 ha-1 and 2.28), respectively. However, it was found on par with pigeonpea + foxtail millet (2:4) with 100 per cent RDF to both component crops (Rs.34,248 ha-1 and 2.25), pigeonpea + sorghum (2:4) with 50 per cent RDF through organic + 50 per cent RDF through inorganic to both component crops (Rs.32,937 ha-1 and 2.19) and pigeonpea + foxtail millet (2:4) with 50 per cent RDF through organic + 50 per cent RDF through inorganic to both component crops (Rs.29,584 ha-1 and 2.06), respectively
