In order to determine the responses of morphological characteristics, yield and yield components of rapeseed (Brassica napus L.) to plant density and weed interference duration, a factorial experiment was conducted using a randomized complete block design with 3 replications at the Rice Research Institute of Iran (RRII) in Rasht, in the 2008 growing season. The factors comprised plant density a...

to evaluate moisture-stress tolerance in reproductive growth stages in five triticale (alamos83, lasko, moreno, prego, and zorro), one bread wheat (roshan) and one durum wheat (osta-gata) cultivars, two field experiments were conducted in 2005-06 cropping season at research farm, isfahan university of technology, lavarak, njafabad, iran. the genotypes were sown in two normal and moisture stress...

Heterosis and the nature and combining ability was studied in 7 × 7 diallel cross in maize for grain yield and yield contributing characters. The significant estimates of GCA and SCA variances suggested the importance of both additive and non-additive gene actions for the expression studied traits. Preponnderance of additive gene action was noticed for ear diameter and 1000-kernel weight and th...

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...

application of superabsorbent material is one of the new methods for moisture storage in the soil. this research was performed in the khajeh research station on the basis of randomized complete block design with three replications in the plots with dimension of 4×5 meter for investigate the effect of different amounts of pumice on water retention capacity in the soil, growth and of spring saffl...

tak-ab is a new winter bread wheat cultivar developed from evaluation of icarda-turkey-cimmyt international bread wheat germplasm to supplementary irrigation areas. study of new cultivars under supplementary irrigation in maragheh and ardebil research stations (2005-2012) showed that, tak-ab had high grain potential under supplementary irrigation conditions. based on results means of grain yiel...
