Response of Micronutrients to Seed Quality in Coriandrum sativum L.

Abstract

The present investigation was carried out at CCS Haryana Agricultural University, Hisar, Haryana during 2017-18 and 2018-19 to access the effect of micronutrients on seed quality in coriander. The experiment consisted of soil and foliar application of micronutrients i.e., recommended dose of fertilizers as control, and recommended dose of fertilizers was used in combination with ferrous sulphate (5, 7.5 and 10 Kg/ha), zinc sulphate (3, 4 and 5 Kg/ha), boric acid (2, 3 and 4 Kg/ha), water spray as soli application. The foliar application of ferrous sulphate (0.4, 0.5 and 0.6 %), zinc sulphate (0.4, 0.5 and 0.6 %) and boric acid (0.2, 0.3 and 0.4 were done at 45 and 90 DAS. The soil application of micronutrients with 5 kg zinc sulphate/ha with recommended dose of fertilizers recorded significantly maximum standard germination (92%), seedling length (24.86 cm), seedling dry weight (3.45 mg), vigour index – I & II (2286.56 & 317.37), catalase (0.490 mg protein min ), -1 -1peroxidase (0.547 mg protein min ), dehydrogenase (0.075 OD g ml ), superoxidase dismutase (0.925 mg protein min )-1 -1 -1 -1 -1 -1, speed of germination (7.54), seedling establishment percentage (85.75%) and mean emergence time in days (11.37).
