Integrated farming system in enhancing the productivity of marginal rice (Oryza sativa) holdings in Goa

A field experiment was conducted at the ICAR Research Complex for. Goa, Old Goa, during 1999–2000 and 2000–2001 to assess the productivity of rice (Oryza sativa L)-based cropping sequences, viz. rice-brinjal (Solarium melongena L), rice-cowpea [Vigna unguiculata (L) Walp.], rice-groundnut [Arachis hypogaea L)-rice-sunnhemp (Crotalaria juncea L.) and sole rice-integrated with poultry and mushroom production, the highest system productivity (21, 487 kg/ha/year) of rice-grain-equivalent yield was recorded with rice-brinjal (Solanum melongena L) system integrated with mushroom and poultry, followed by rice-cowpea (18, 027 kg/ha/year) and rice-groundnut system (16, 922 kg/ha/year). The contribution of crops towards the system productivity ranged from 33 to 52%, while the share of poultry and mushroom production was 28 to 39% and 20 to 28% respectively.
