A total of 10 field experiments were carried out during the 1998 and 1999 growing seasons both in the north (Lleida) and the south (Granada and Jerez) of Spain. In Lleida and Granada, the experiments were conducted under both irrigated and rainfed conditions, while the Jerez trials were carried out only under rainfed conditions. Ten durum wheat genotypes were used in this study. Quality determi...

the evaluation of gene bank germplasm collection for morpho-physiological traits is important in the breeding programs. although phenotypic variation was considered, it is likely that this phenotypic variation is largely genetic and therefore directly useable for breeders, especially for those traits with high heritability such as heading and maturity time, plant height, kernel number and weigh...

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...

A field experiment was conducted during kharif season of 2010 and 2011 to investigate the optimization of nitrogen levels under different age of seedlings transplanted on growth, chlorophyll content, yield and economics of hybrid rice. Fifteen treatment combinations consisted of three levels of seedlings age (10, 20 and 30 days) and five levels of nitrogen viz. N0, N50, N100, N150 and N200 kg h...

drought stress is one of the most important environmental stresses that affect yield of bread wheat strongly. considering that the yield achieved with the interaction of a large number of plant traits and environment, so the morphological and agronomical traits, can serve as selection criteria under environmental conditions. by genetic analysis and estimation of inheritance and mode of gene act...

in order to evaluate the effects of different organic and chemical fertilizers on yield, yield components and seed oil content of sesame an experiment was conducted in a split plot layout based on randomized complete block design with four replications at research station, faculty of agriculture, ferdowsi university of mashhad in year 2006. four types of fertilizer, including chemical fertilize...
