Abstract:

The field experiment was conducted during Virippu season 2016-’17 in the low land rice fields. Seven rice based farming systems viz., T1: rice succeeding fallow; T2: rice succeeding amaranthus; T3: rice succeeding culinary melon; T4: rice succeeding fodder cowpea; T5: (rice + fish) succeeding (amaranthus + fish); T6: (rice + fish) succeeding (culinary melon + fish); T7: (rice + fish) succeeding (fodder cowpea + fish) were evaluated for assessing the effect of crop diversification and fish integration on the productivity of rice. Diversification of summer rice fallows with different crops resulted in a yield improvement to the tune of 10.22 per cent over the rice succeeding fallow. Whereas, in fish integrated systems, the yield improvement was 15.56 per cent more than the sole crop of rice. The grain yield (6.62 t ha-1) and straw yield (6.84 t ha-1) were significantly higher in rice + fish succeeding fodder cowpea + fish. The productivity of rice grain and straw was less in the rice – rice – fallow system. In general, crop diversification and fish integration resulted in productivity improvement in rice based farming systems.
