this study was aimed to assess the effects of excess boron on 59 genetically divergent wheat accessions and to identify those with high and stable yields under a range of soil boron concentrations. the second aim was to test the applicability of a laboratory technique performed at juvenile stages of development in estimating field boron tolerance. the study comprised a control and three boron t...

Abstract The article presents data on the study of influence an agricultural forecrop yield winter wheat varieties Moskovskaya 40 and Nemchinovskaya 17. experiments were carried out in Ryazan region, Russia, dark gray forest soils Malinki enterprise Mikhailovsky district. most effective experiment was vetch-oat mixture for variety 17, with following structure: grains per spike are 46.8 pieces, ...

the effect of late planting heat stress on yield and yield components was studied in 11 barley lines from icarda and one cultivar from iran (izeh) during two years (2005-2007) in gachsaran dry-land agricultural research station. each line was planted in a 6-rowed plot at two dates: normal planting (middle of november) and late planting (end of december) with three replications using a randomize...

Abstract Field experiment ware carried out at the Agricultural Research Station of Basrah University College Agriculture, north Basra governorate during winter seasons 2020/2021 and 2021/2022 to study growth yield three cultivars wheat (IPA99, BANGIL JAAD) urea- nitrogen applied four rate (0,60,120 180)kg ha -1 as comported Nano-N (0, 15 30) L . The was designed factorial randomized complete de...

lead to continuing effects for increasing extensive of yield by means of advanced agronomic operations and selection of high yielding resistant genotypes. there fore, due to evaluation and determination of best effective traits in improvement of yield and grain quality of local populations of winter wheat, an experiment was carried out in uremia agricultural research station, on 30 local popula...

The study was carried out to evaluate the combining ability and heterosis of seven parents their 21 half-diallel F2 populations for yield quality traits during 2013-14 season in randomized complete block design with three replications. Significant differences were observed among genotypes, GCA (general ability) SCA (specific effects all traits, except spike length. best combiner identified as E...

Wheat plants (Triticum aestivum L., cv. Warigal) were subjected to 20 d of water deficit during the period of endosperm cell division. Drought accentuated the differences in final grain weight between spikelets and between grains within spikelets. The distal grains of top spikelets were most affected by drought. The maximum number of endosperm cells was, respectively, 30 and 40 per cent lower i...

The research was applied at Station No. 1 belonging to the College of Agriculture, University Anbar, determine most appropriate traits for improving barley grain yield during season 2021-2022 by designing randomized complete blocks in split plots with three replications, purpose studying path way coefficient and its components five cultivars (Samir , Aksad 617, Amal, Buraq Abba 265) seed rates ...
