to investigate the changes in yield and yield components of dry land wheat (triticum aestivum l. cv agosta), under the influence of residue and nitrogen levels and different tillage practices, a field experiment was conducted during the 2006-2007 growing season, in the agricultural research station of the college of agriculture, shiraz university, iran. the experiment was designed as a split-sp...

Objective: Wheat is the most important crop in Iran. Self sufficiency in wheat production is one of the economic and food safety policies in the country. In spite of the efforts which have been made in this area, the mean of wheat yield in Iran is less than its world average. Methods: In order to identifying of the high yielding wheat lines with optimal characteristics and to determine the trai...

In North Africa, barley (Hordeum vulgare L) is the second most cultivated cereal. Tunisia, in mining areas with possible Cd soil contamination. The accumulation of was studied 36 African cultivars cultured during 6 months on control and containing 10 ppm Cd. Cadmium did not affect germination morphology any cultivar. However, induced variable effects biomass according to cultivar Lemsi sensitiv...

Soybean tolerance to defoliation may be affected by population density, as the plant interferes with crop leaf area index . This study aimed evaluate effect of at beginning pod formation on agronomic performance soybean different densities. The experiment was conducted under field conditions in Campos Novos, SC, Brazil, during 2016/2017 and 2017/2018 growing season. experimental design a random...

To identifying of the high yielding wheat lines with optimal characteristics and to determine the traits which could be used as the selection index for increasing of grain yield, 40 recombinant inbred lines derived from a cross between Norstar and Zagros cultivars were evaluated in a randomized complete block design with three replications. The measured characters consisted of peduncle weight, ...

soil salinity poses considerable and increasing problems for agriculture, and is receiving much attention from plant breeders. the identification of genes whose expression enables plants to adapt to and/or tolerate salt stress is essential for breeding programs, but little is known about the genetic mechanisms of traits in saline conditions. the data obtained from 75 families produced by crossi...
