Effect of Potassium and Sulphur on Nutrient Uptake and Economics of Coriander (Coriandrum sativum L.)

Abstract

A field experiment was conducted during rabi 2021-22 at Agronomy Instructional Farm, Sardarkrushinagar Dantiwada Agricultural University, Sardarkrushinagar, Gujarat on loamy sand soil to study the response of coriander (Coriandrum sativum L.) to potassium and sulphur. The experiment was laid out in factorial randomized block design (FRBD) consisted three level each of potassium (0, 20 and 40 kg/ha) and sulphur (0, 15 and 30 kg/ha) and replicated four times. Application of 40 kg K2O/ha gave significantly higher potassium content and uptake in seed and straw. However, different levels of potassium on sulphur content in seed and straw of coriander was not significant. The maximum sulphur content and uptake in seed and straw was recorded with application of 30 kg S/ha but sulphur application do not influence on potassium content in seed and straw. Application of 40 kg K2O /ha and to 30 kg S/ha gave significantly higher gross and net realizations as well as BCR. While, application of 20 kg K2O /ha and 15 kg S/ha resulted in the higher ICBR.
