Abstract


A field experiment was conducted at Agricultural Research Station Mundgod, Karnataka in lowland during 1995-96 and 1996-97 to study the residual effect of organics (eupatorium and glyricidia) and biofertilizers (azolla and vermicompost) on the performance of sequential crops (blackgram, redgram, dolichos (avare), soybean, groundnut and sunflower) grown under protective  irrigations.The yield response of various organic and biofertilizer treatment varied with little change during 1995-96 amd1996-97. Interms of paddy grain equivalent the pooled results indicated that all organic and biofertilizer treatments were onpar and significantly superior to control. The extent of yield increase was 30.25, 25.53,16.67 and 14.52 per cent under glyricidia, Azolla vermicompost and eupatorium treatments respectively over control. Among the crops in terms of rice grain equivalent polled results indicated the significant superiority of groundnut (4444kg/ha) over other crops. Redgram (363kg/ha), blackgram (3639kg/ha) and avare (3330kg/ha) were founds to be on par the extent of increase in net returns over control was 50.79, 40.10, 28.6 and 18.6 per cent under glyricidia azolla, vermicompost and eupatorium treatments, respectively. With respect to crops net returns of blackgram (Rs. 12213 per ha), redgram (Rs.11823 per ha) and groundnut(Rs.11667per ha) were on par and were significantly higher than soybean (Rs. 4142 per ha) and sunflower(Rs. 9010 per ha). Among the crops grown, blackgram and redgram found to be more suitable due to their yielding ability, higher net returns and high benefit cost ratio.
