the objectives of the present study were to evaluate spring wheat recombinant inbred lines (rils) of diverse origin by estimating genetic parameters viz., variability, character association, cluster analysis, and principal component analysis (pca) for spot blotch resistance and yield components at bhu agricultural research farm during 2010-2011. grain yield per plot was significantly and positi...

Accurate estimation of sink capacity in rice (grain number × potential grain size), independent filling, is necessary for considering source – interactions. However, how to measure size still a matter debate. Here, we investigated the effect modifying grain-filling environment on 1000-grain weight grains screened by specific gravity or brown thickness, projected area (‘grain area’), husk as can...

An experimental trial of nine rice genotypes was conducted in the Agronomy field Institute Agriculture and Animal Science (IAAS) Paklihawa Campus under a randomized block design layout with three replications from July to November 2022. The aim study genetic variability analyze character association yield yield-attributing components their direct indirect effect on grain reproductive drought st...

Seventy genotypes of rice (Oryza sativa L.) were evaluated during Kharif 2012 to study the nature and extent of correlation among yield and yield attributing characters, days to 50 per cent flowering, days to maturity, number of effective tillers per plant, plant height, panicle length, number of grains per panicle, 1000-grain weight, grain yield per plant, kernel length, kernel breadth and L/B...


 Field experiment was carried out to study the effect of different tillage systems and skipping irrigation at growth stages along with or without foliar applied potassium on phenology, yield maize hybrid. Results revealed that maximum grains per cob (381), 1000-grains weight (281.00 g), grain (7.82 t ha-1) biological (14.78 were observed in conventional system as compared zero tillage. Re...

This study set out to investigate the effect of bio-fertilizers containing nitrogen-fixing bacteria and phosphorus on grain yield and yield components of Faba bean. To this end a factorial experiment on the basis of randomized complete block design with four replications was conducted in Behbahan region at South eastern part of Khuzestan Province of Iran. The experimental treatments included Ni...

Physical characteristics of eight maize varieties /lines (EV-6089, Sahiwal-2002, Golden, 34N43, EV-1098, Sultan, China-1, EV-20), seven yellow and one white, obtained from Maize and Millet Research Institute, Yousaf Wala, Sahiwal, Punjab, Pakistan, in free choice test, were correlated with biological parameters of life history of Sitotroga cerealella (Oliv.) (Gelechiidae: Lepidoptera). S. cerea...
