Transplanting or pot culture has been mentioned as a promising approach to increase crop yield and decrease irrigation water use in recent years. Using simulation models to assess pot culture is a valuable way in investigating the effect on yield, water consumption and other properties of crops such as soybean. For this purpose, several pot culture levels (seedling sizes) plus direct sowing wer...

Growth and grain yield of irrigated barley cultivars (Valfajr, Binam and Raihaneh) was investigated at 4 sowing dates (6, 22 Oct. and 14, 20 Nov.) in Karaj region. The effect of sowing date, genotype and their interaction on grain yield were statistically significant. Early and late sowing enhanced cold damage. However, the damage was more in late sowings. It was estimated that the optimum sowi...

Terminal heat stress in hot and dry conditions like Ahwaz reduces the quantitative and qualitative yield of wheat. In order to study the effect of terminal heat stress on grain filling period duration, grain filling rate and quantitative and qualitative yield of 20 spring bread wheat cultivars, a field experiment was conducted in Research Farm of Agricultural Sciences and Natural Resources Univ...

In order to evaluate the effects of sowing date and intra rows spacing on yield, yield components and some phytochemical characteristics in Roselle, a field experiment was conducted as a split plot layout based on randomized complete block design with three replications in 2013 and 2014 growing seasons. Five sowing dates were considered as the main plots (11th and 30th of March, 14th of April, ...

This study was conducted to determine whether selecting an optimum sowing date couldimprove yield. The experiment consisted of sowing a film-covered, drip-irrigated cotton field onfour sowing dates from April to May in 2011-2012 at the Agrometeorological ExperimentalStation of Wulanwusu, which was in an arid region of north-western China. Late sowing datesproduced less yield and water-use effic...

In order to study the effect of sowing date on grain yield and grain-filling duration of triticale cultivars, an experiment was conducted based on strip-plot experiment with four replicates at Ramin Agricultural Research and Educational Center (RAREC) during 2009-10. The sowing date treatments were November, 10th (Aban, 20th) and December, 4th (Azar, 14th) and the cultivars include: ET.79-3،ET....

Grain yield of bread wheat (Triticum aestivum L.) is reduced by heat stress, particularly when occurs in reproductive phase, in many countries worldwide, including Iran. In order to study the effects of different levels of nitrogen and cytokinin on wheat yield and yield components at normal and heat stress conditions in Khuzestan, Iran, this research was conducted at Ramin Agriculture and Natur...
