this research set out to evaluate the effect of combined biological and chemical nitrogen fertilizers on some corn hybrids. to this end an experiment was conducted as split plot on the basis of randomized complete block design with four replications. main plots were included: use of chemical and biological fertilizers in four levels: 100% chemical fertilizer, 75% chemical fertilizer + 100% bio-...

Grain size and shape associated with yield and milling quality are important traits in wheat domestication and breeding. To reveal the genetic factors on the D genome that control grain size and shape variation, we conducted analysis of quantitative trait loci (QTL) using the F2 and F2:3 populations derived from a common allohexaploid wheat line TAA10 and a synthetic allohexaploid wheat XX329, ...

effects of five seeding rates (350, 425, 500, 575 and 650 seeds per m2) on four wheat cultivars (kavir, mahdavi, shiraz and roshan) were studied under salinity stress, during 2000-2001 crop seasons in roodasht agricultural research station, esfahan. a factorial experiment based on randomized complete block design with three replications was used. plants were irrigated with saline water (with ec...

new sources of maize resistance to the maize weevil, sitophilus zeamais infestation are indispensable in successful breeding programs against post harvest grain damage. the study investigated the characters and mechanisms that confer resistance to weevil infestation using twenty elite maize genotypes. detailed morphological and physical studies were conducted on whole-maize grain. the grain hul...

Abstract The research was carried out in three vegetative seasons 2015/16, 2016/17, and 2018/19, on an experimental plot Padinska Skela, Belgrade, Serbia. supplement included four NPK treatments (kg ha −1 ) foliar treatment with effective microorganisms (EM 7 l T1-129: 60: 60; T2-129: 60 + 1 EM; T3-106: 2 EM ; T4-83: 3 EM. Four wheat genotypes were sown (Ratarica, Pobeda, Nogal, Apache). Thousa...

The present investigation conducted on 80 accessions of wheat during 2018-19 at Main Experiment Station (MES) A.N.D. University Agriculture and Technology, Kumarganj, Ayodhya (U.P.) to evaluate character association genetic divergence for the identification most diverse promising genotypes. experiment was laid out in Augmented Block Design. observations were recorded various morphological physi...

Spike hetero branching wheat (Triticum aestivum) (SHBW) has one main rachis, but has branched rachises at lower parts of main rachis. This type of spike could increase greatly grain number by bearing grain in branching rachis. In this study, field experiments were conducted at three locations in Huanghuai wheat zone during two growing seasons (2008-2010). The rachises length, node number, grain...

to determine the correlation between grain yield and its components in some grain corn hybrids and their cause and effect relationships in various fertilizer application methods, an experiment was carried out as split plot based on randomized complete block design with two fertilizer application methods (urea foliar application and soil application method), four grain corn hybrids (ns 640, kons...
