in this study the effects of source limitation on grain yield of twelve barley cultivars (‘aras’,‘jonub’,‘reihan’,‘zarjou’,‘sararoud’,‘sahra’,‘fajr30’,‘karoun’,‘gorgan’,‘makouei ’and ‘nosrat(’ under post anthesis water deficiency were studied. source limitation treatments were included that control, removing of awn, leaves below flag leaf, flag leaf and spike photosynthesis. all source limitati...

in order to evaluate yield and yield components properties of cold-tolerant chickpea under winter sowing and complementary irrigation conditions, two experiments in the context of partial balanced block design with 81 chickpea genotypes and three replications were carried out. complementary irrigation was performed during growing season including irrigation immediately after sowing, 20 days aft...

Abstract The aim of the research is to study effect stages spraying nano-microelements on some yield characteristics and economic feasibility wheat varieties. Soil with a mixture clay texture using split plank design random complete sectors (R.C.B.D) cultivars coded (Abu Ragheef V1, Baghdad V2, Babil V3, Aba 99 V4) occupied main panels, while (tillering stage S1, booting S2, flowering S3) secon...

We present a radiative transfer model which computes the spectral energy distribution of a passive, irradiated circumstellar disk, assuming the grains are in radiative equilibrium. Dependence on the radial density profile, grain temperature estimation, and optical depth profiles on the output SED are discussed. The best fit model for HR 4796A has a minimum and maximum spherical grain size of 2....

Intraspecific hybridization in winter rye selection ( Secale cereale L. ssp. ) is a source of intrapopulation genotypic variability with the possibility using effect interpopulation heterosis. The inheritance crop yield, regeneration degree after overwintering and weight 1000 grains reciprocal back F 1 intervarietal hybrids was established. Different types prevailed crossings. had specificity. ...

Abstract Field experiment was carried out during the 2018 growing season in central Kut nursery located within district of Wasit Province Iraq, with four treatments and three replicates a randomized complete block design (RCBD) to response maize foliar application potassium irrigated by basin irrigation method. Foliar spraying (K 2 O 43%) as follows; control ), 1000 1 2000 ) 3000 3 Mg.L −1 . Th...

Aim. To determine the influence of alternative alleles Ppd-D1 gene and phenotypic differences in duration need for vernalization their interaction on earing time grain yield recombinant lines bread winter wheat. Methods. Growing plants field vegetation site, PCR with specific primers Ppd-B1c genes, phenological observations, artificial vernalization, statistical analysis. Results. 136 F7 from c...

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...
