dc.description.abstract	Investigation was conducted at Horticulture Research Station, Arasikere, Karnataka, during kharif and summer seasons of 2012-14 to study the performance of different cropping sequences with vegetable crops and effect of integrated nutrient management practices on growth, yield of vegetable crops and soil properties under coconut based cropping system (CBCS). The experiment consisted of three cropping sequences of vegetable crops viz., M1-okra-fallow (2012-13) & Tomato-fallow (2013-14), M2-green mannure-cucumber, M3-baby corn-gherkin and coconut monocropping as control. Four INM practices viz., S1-Inorganic fertilizer alone (100%), S2-5 ton FYM+75% NPK+25%N by vermicompost, S3-5 ton FYM+50% NPK+25% N by vermicompost+25% N by CCP+IIHR micronutrient spray and S4-5 ton FYM+50% N by vermicompost+50% N by CCP+vermiwash spray + Azatobacter was carried out in FRBD with five replications during 2012-14. The study revealed that growth and yield of all the vegetable crops grown under coconut garden were significantly influenced by INM practices. The yield of all the vegetable crops increased significantly under S3 treatment when compared to other treatments. The nut yield of coconut was improved under vegetable intercropping when compared to monocropping. Studies on soil properties showed that there was significant reduction in soil pH and EC and increase in OC, N, P, K, Ca, Mg, Fe and B under cropping sequence compared to monocropping and initial status. Leaf nutrient status of coconut palm was increased under cropping sequences when compared to monocropping. The microbial population was significantly highest under 100% organic treatment (S4) when compared to other treatments and the lowest was in 100% inorganic treatment (S1). Carbon sequestration by coconut palm (above ground) was the highest under CBCS when compared to monocropping and soil carbon sequestration was significantly highest under M3 sequence at 15-30 cm depth, S4 treatment during both the years at both the depths compared to other treatments. The coconut equivalent yield under CBCS was significantly the highest under M3 (2012-13) and M1 (2013-14). In CBCS, M3 sequence recorded significantly higher net income and B:C ratio during 2012-13 and M1 sequence during 2013-14, S1 treatment during both the years and coconut monocropping (M4) and S4 (100% organic) recorded the lowest.	en_US
