Effect of PGRs, sowing time and varieties on growth of coriander (Coriandrum sativum L.) under gird region conditions

Abstract

The present investigation entitled “Influence of PGRs, sowing time and varieties on growth of coriander (Coriandrum sativum L.)” The present experiment was laid out in the experimental field of department of Horticulture, College of Agriculture, Rajmata Vijayaraje Scindia Krishi Vishwa Vidyalaya, Gwalior (M.P.) during first year (2018 – 19), second year (2019 – 20) and pooled with 24 treatment combinations that were laid out in split plot design and replicated three times. Sowing time and varieties were assigned to main plots whereas, plant growth regulators to sub plots. The observations were recorded on different aspects of leaf area per plant, leaf area index, crop growth rate, relative crop growth rate, days taken to first flowering and days taken to 50% flowering. The result of experiment revealed that the D1 (last week of December) significantly improved growth parameters among all the date of sowing D2 (first week of January) and variety V1 (RCr-41) was significantly always affected the all growth parameters, whereas PGRs T3 (Thiourea @ 1000 ppm) enhanced all the growth parameters at different growth stages.
