Constrains faced by farmers in different (Drip, Sprinkler and Flood) irrigation methods and suggestions given by them in Arecanut cultivation at Chitradurga district of Karnataka

Abstract

The present investigation was carried out to estimate magnitude of genetic variability in thirty maintainer lines of pearl millet for ten morphological characters. These maintainer lines were planted in randomized block design with three replications during Kharif 2019 at Research Farm, S.K.N. College of Agriculture, SKNAU, Jobner (Rajasthan). Analysis of variance indicated presence of significant genetic variability among the maintainer lines for all ten characters. The estimates of phenotypic coefficient of variation (PCV) exceeded genotypic coefficient of variation (GCV) for each of the ten characters studied indicating influence of environment on character expression, thereby, selection may be misleading seldom. High estimates of heritability coupled with high genetic advance (as per cent of mean) were recorded for days to 50% flowering, plant height, ear head length, ear head girth, 1000-grain weight, biological yield per plant and grain yield per plant.
