ABSTRACT
A study was conducted on wheat (Triticum aestivum L.) in laboratory at Acharya Narendra Deva University of Agriculture and Technology, Kumarganj, Ayodhya, Uttar Pradesh, during the 2019–20 for correlation and heritability analysis for seed quality under controlled conditions in wheat. In a wheat crop research, 30 germplasm were tested using three checks each for the parameters of seed weight, seed width, seed length, shoot length, root length, seedling length, seedling dry weight, germination (%), first count, final count, and vigour index-I and vigour index-II. In this study, the germplasm was assessed using parameters and the correlation coefficient. The vigour index-II demonstrated a very significant positive phenotypic connection with root length (0.828), final count (0.564), and first count (0.552), as well as a genotypically significant positive correlation with final count (1.165), root length (0.867), and first count (0.552). The high estimates (>15%) of phenotypic coefficient of variation (PCV) and genotypic coefficient of variation (GCV) were registered in the case of vigour index-I (PCV=17.36%, GCV=17.24%), shoot length (PCV=15.96%, GCV= 15.77%), seed width (PCV= 15.35%, GCV= 15.19%). The moderate estimate (10%) of PCV and GCV were recorded for root length (PCV=12.72%, GCV=12.56%), and seedling length (PCV= 11.46, GCV= 11.30).
ABSTRACT
Among the various treatments evaluated for their bio-rational effect against mustard aphid on Indian mustard during year- 2021-22 at C. S. Azad University of Agriculture & Technology Kanpur Uttar Pradesh, the descending order are the followed treatments are NSKE @10% > NSKE @5% > Cow Urine @ 10% > Verticillium lecanii @ 1.5kg/ha. > Lantana leaf extract @ 10 % > Castor leaf extract @ 10% > Lantana leaf extract @ 5 % > Castor leaf extract @ 5% > Cow Urine @ 5%. India, the spray of NSKE 10% @ 60 lit/ha followed by NSKE 5 % @ 30 lit/ha was proved to be the best treatments with pooled mean aphid population of 5.42, 5.10, 4.96, 4.85, 5.39, 5.26, 5.42, 5.23, 5.13, and 7.29 aphid/pant in the control after 1, 3, 5 and 7 days of treatment, respectively. The treatment NSKE 10 % was proved best and significantly superior over all treatments with highest reduction of Infestation of Lipaphis erysimi kalt. in both the years.
