Enhancement of yield components and seed quality parameters by growth regulators in lentil (Lens culinaris Medik.)

Abstract

The present study were carried out in the Department of Genetics and Plant Breeding, N. D. University of Agriculture and Technology, Kumarganj Faizabad during rabi season 2015-16 and 2016-17 entitled “Enhancement of yield components and seed quality parameters by growth regulators in lentil (Lens culinaris Medik.)” The objective of the study was To standardize growth regulators optimization seed germination and vigour potential, with the selection of GA3, Kinetin and NAA for exploitation of its, maximum grain yield in lentil under the agro-climatic conditions. The 19 treatments of growth regulators and seed priming for lentil variety (NDL-1) was evaluated following 13 quantitative characters viz., Days to 50% flowering, Days to maturity, plant height on 30 and 60 days, number of branch on 30 and 60 days number of pods per plant, number of seeds per pod, 1000 seed weight biological yield/plant harvest index (%), seed yield per plant (g), seed germination, seedling length vigour index. The treatment T3 (GA3 150 ppm (priming) was found best in, all the treatments. Maximum number of pods per plant (46.69) and seed yield/plant (2.68 g) was recorded with T3 (GA3 150 ppm (seed priming).
