Abstract
The field experiment was conducted at College Agronomy Farm, Anand Agricultural University, Anand to study the "Effect of integrated nutrient management on cabbage (Brassica oleracea var. capitata L.) under middle Gujarat conditions" during rabi season of the year 2013-2014. The soil of experimental field was loamy sand in texture, low in organic carbon, medium in available phosphorus and available potash with a 7.8 and 7.7 pH at 0-15 and 15-30 cm soil depth, respectively. The experiment was laid out in RBD with four replications. The nutrient management treatments were 100 % RDN + FYM @ 20 t ha-1 (T1), 100 % RDN + FYM @ 20 t ha-1 + Azotobactor + PSB (T2), 100 % RDN + vermicompost @ 10 t ha-1 (T3), 100 % RDN + vermicompost @ 10 t ha-1 + Azotobactor + PSB (T4), 100 % RDN + FYM @ 10 t ha-1 (T5), 100 % RDN + FYM @ 10 t ha-1 + Azotobactor + PSB (T6), 75 % RDN + FYM @ 10 t ha-1 (T7), 75 % RDN + FYM @ 10 t ha-1 + Azotobactor + PSB (T8), 75 % RDN + vermicompost @ 5 t ha-1 (T8) and 75 % RDN + vermicompost @ 5 t ha-1 + Azotobactor + PSB (T10). The results revealed that various treatments employed on the cabbage variety Golden Cross showed significant influence on growth attributes lAz., plant height at harvest and leaf area index as well as yield attributes viz., weight of cabbage head, volume of cabbage head and diameter of cabbage head. Significantly superior results were shown under application of 100 % RDN + vermicompost @ 10 t ha-1 + Azotobactor + PSB in the case of plant height at harvest, leaf area index, weight of cabbage head, volume of cabbage head and diameter of cabbage head. While, higher head compactness of cabbage was recorded under INM treatment Ty (100 % RDN + vermicompost @ 10 t ha-1). Head 3deld of cabbage was significantly higher under treatment T4 (100 % RDN + vermicompost @ 10 t ha-1 + Azotobactor + PSB), it increased 11.65 per cent yield over control treatment T1 (100 % RDN + FYM@20tha-1). Different INM treatments failed to reflect their significant effect on physico-chemical parameters of soil i.e., EC, pH, available phosphorus, available potash content and bulk density of soil after harvest of the crop except organic carbon content of soil after harvest of the crop. The economics calculated based on head yield indicated that, maximum net realization of ₹244467 ha-1 was observed under treatment T4 (100 % RDN + vermicompost @ 10 t ha-1 + Azotobactor + PSB) followed by the treatment T6 (100 % RDN + FYM @ 10 t ha-1 + Azotobactor + PSB) ₹243267 ha-1. Whereas, maximum BCR was observed under the treatment T6 (100 % RDN + FYM @ 10 t ha-1 + Azotobactor + PSB). Thus based on the results of the present investigation, it can be concluded that for maximizing the production and net returns an integrated approach can be adopted in cabbage (Golden Cross). Application of 100 % RDN + vermicompost @ 10 t ha-1 or FYM @ 10 t ha-1 + Azotobactor + PSB was found superior for the cabbage crop under middle Gujarat conditions.
