Abstract: INTEGRATED FARMING SYSTEMS FOR COASTAL t REGION OF GOA B.L.MANJUNATH 2001 Dr. C.J. ITNAL Major Advisor ABSTRACT Field experiments were conducted for two years at I CAR Research Complex for Goa, Old Goa, to identify profitable farming system options for an average hoiding size prevailing in Goa. Recycling of paddy straw in rice with mushroom spent substrate in 2:1 ratio was found profitable both for rice and rice based cropping systems. Rice- brinjal system recorded the highest productivity (11122 kg/ha) under protective irrigation while rice-cowpea under residual moisture conditions ( 7662 kg/ha). These systems recorded better net returns (Rs.46440/ha and Rs. 42570/ha, respectively) with higher per day return (Rs.163 and Rs. 195/day, respectively). Further, integration of cropping systems with poultry and mushroom added productivity to the tune of 6060 and 3660 kg/ha, respectively with additionai net returns and empioyment on the farm. Among the perennial forage grasses and legumes intercropped in coconut, PBN-16 + Cenfrosema and DHN-3 + Cenfrosema combination (1:1) recorded 26.9 and 15.9 per cent higher forage yield over NB-21 combination with during both the years of experimentation. Further, intercropping in coconut and integration with dairy showed substantial improvement in the net feturns from the system( Rs.48530 /ha) over mono cropping ( Rs. 6225/ha). In addition, dairy integration generated employment to an extent of 356 man days/ha. The system provided scope for recycling of nutrients through coconut composting using cow dung from the integrated dairy with improvement in soil fertility. The system also enhanced the yield of coconut over pre-experimental period. On the basis of data generated over a period of two years, integration of mushroom and poultry enterprises with rice-brinjal and rice-cowpea systems provide sustainability in terms of recycling of farm waste, employment generation and economic returns for the famiiy round the year. Further, to make coconut production a viable proposition, intercropping with high yielding perennial forage grasses like PBN-16 and DHN-3 with perennial forage legume Centrosema in 1.1 ratio be recommended. Maintenance of two milch cows in the system would bring stability to the system with enhanced net returns, additional employment opportunities and improvement in soil fertility.
