Thirty genotypes of chilli were evaluated in RBD with three replications at vegetable research farm, CHF, CAU, Pasighat, Arunachal Pradesh, India during kharif, 2011. Variability, correlation and path analysis were carried out to study the character association and contribution, respectively. Analysis of variance revealed significant differences among the genotypes for all traits. High PCV and GCV, heritability, genetic advance were observed for days to first flowering, plant height, number of seed per fruit, number of fruit per plant, ascorbic acid and fruit yield per plant. Correlation indicated that fruit yield per plant was positively and significantly correlated with number of branch per plant, number of fruit per plant and chlorophyll content while negative and significant association was established with ascorbic acid content. Maximum positive direct effect on fruit yield per plant was imposed by fruit weight, number of fruit per plant, number of seed per fruit and capsaicin content.
to develop site specific NPK requirements of potato variety Kufri Jyoti on growth and yield attributes. The experiments included seven different treatments of Nitrogen, Phosphorous and Potassium percentage and were evaluated in Randomized Block Design with three replications. Results showed that among the all the treatments maximum plant height was recorded in T 3 (150% RDF of NPK), maximum number of shoots per plant was observed in T 2 (50% RDF of NPK) and highest tuber yield was recorded (18.15 t ha -1 ) in 150% RDF. Therefore, it was indicated that in both the years, the yield of potato greatly depend on the dose of fertilizers i.e., NPK application which influenced progressively in terms of producing highest tuber yield and net returns of the crop.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
