Influence of zinc and copper on yield and soil properties under coriander crop in lateritic soils of Konkan region

Abstract

Coriander (Coriandrum sativum L.) is an annual herb mainly cultivated for its tender green leaves and seeds. In order to study the influence of zinc and copper on yield and soil properties under coriander crop in lateritic soils of Konkan region, the present investigation was undertaken. The highest yield (11.18 t ha-1) of coriander was obtained with the application of 0.5 percent ZnSO4 through foliar spray along with 100 percent RDF (T5). However, the yield of coriander (10.56 t ha-1) with the soil application of ZnSO4 @ 20 kg ha-1 along with 100 percent RDF(T6) which is at par with the treatment T5. The application of micronutrients did not have a significant effect on pH and Electric conductivity of the soil at harvest. The organic carbon, nitrogen, phosphorous and potassium of the soil at harvest was found to be significantly influenced by the application of micronutrients.
