Corn (&a mays L.) growth has been shown to be affected by planting date and amount of residue on the soil surface. The objective of this study was to determine if the adverse effects of cool soil temperatures on early seedling growth often associated with surface residues can be overcome by planting at later dates. Corn was planted at several planting dates (late April through early June) into ...
drought stress is one of the important environmental factors reducing grain yield of plants in arid and semiarid regions. study the effect of water deficit stress on yield, water use efficiency and harvest index of sesame varieties, this experiment was conducted as a split plot based on a randomized complete block design with three replications, at agriculture and natural resources research cen...
Mung bean is one of tropical and semitropical pulses that is important in food, fodder, green manure and improves soil fertility and is a cheap source of protein in human direct consumption. The use of zeolite in soils with heavy texture, because it keeps moisture and nutrients around the seeds and roots is very important. On the other hand, the application of techniques of improving seed quali...
In order to study the effect of on-farm seed priming using tap water and zinc sulfate solution with 0.03% zinc on yield and yield components of two intermediate maturing maize cultivars, a factorial experiment was carried out in complete randomized block design with three replications in Research Farm of Bu Ali University, Hamedan, Iran in 2011. Seed priming consisted of three levels (priming w...
in order to evaluate the effect of sulphur fertilizer and nitrogen split application on yield and its components of sunflower (helianthus annuus l .),an experiment was carried out at the research field of birjand faculty of agriculture in 2008 as factorial in complete randomized block design with three replicates.the treatments were sulphur fertilizer in four levels ( 0 , 200 , 400 and 800 kg/h...
introduction safflower is native to iran, and is cultivated for high adaptability, low water requirement, resistance to drought and useful unsaturated fatty acid (ashri et al., 1977). identification of effective agronomic traits and relationship between them are important aims under water stress conditions. among these characters, grain yield is the most important trait that is genetically poly...
introduction nowadays oilseed crops are considered as the second most important sources of energy in the diet. in this regard, cultivation of oilseed crops such as safflower (carthamus tinctorius l.) is important due to quality of oil seed and medicinal properties. different planting dates leads to adaptation of vegetative and reproductive growth of plant to temperature, day-length and various ...
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...
in order to investigate the response of cotton cultivars (gossypium hirsutum l.) to conventional-cropping and double-cropping systems a field experiment was conducted as split plot based on randomized completely block design with three replications at gonabad agriculture and natural resources research station during growing season of 2009-2010. the treatments included of recommended planting da...
This experiment was conducted at the Agricultural Research Station of Isfahan University of Technolgy in 2006 to evaluate the effects of planting pattern and the level of soil moisture on two safflower cultivars. A factorial split plot arrangement was used in a randomized complete block design with three replications. Two planting patternS (flat and bed planting) and two levels of soil moisture...
