The goal of this research is the determining of planting date and providing agricultural calendar for corn in Kermanshah province using climatic elements of temperature and rain fall. so, at first, long term climatic statistics are collected from 2001 to 2011 and then considered to temperature and rain fall parameters like absolute maximum and minimum in region during growth period, planti...
Unsuitable planting and weed competition are the most important factors that greatly reduce the yield of bean. In order to study the effect of planting date on yield and yield components of three white bean cultivars in weed infest and weed free condition a factorial experiment with randomized complete block design and three replications was carried out at Semirom in 2009. The treatments were p...

Supplementary irrigation is one of the most effective field management practices to improve water productivity and crop yield in rainfed conditions. Time of supplementary irrigation is another important parameter affecting the enhancement of yield. In order to study the effect of supplementary irrigation time as well as planting date, two factors, namely: 1) supplementary irrigation (No irrigat...
The Northeast China (NEC) was the most important agriculture areas and known as the Golden-Maize-Belt. Based on observed crop data and crop model, we design four simulating experiments and separate relative impacts and contribution under climate change, planting date shift, and varieties change as well change of varieties and planting date. Without planting date and varieties change, maize yiel...
In order to investigate the best planting time and rice cultivars for the conditions in Khuzestan Province, seven high quality cultivars of rice namely Domsiah, Binam, Ramasanali Tarom, Sang Tarom, Hasansarai, Tarom Mahalli, Daylamani and Anboori were selected and studied in 4 planting dates starting in Mid-May, with intervals of 15 days. The experiment was conducted as a split plot design in r...
In order to study the impact of drought stress and planting date on safflower yield and yield components, an experiment was performed in Tabriz region in 2011. The experiment was carried out as split-split plot based on randomized complete block design. The main factor which was applied as split plot includes drought stress with three levels: (S1) 80 ± 3 mm evaporation from basin level of cla...
For maize (Zea mays L.), early planting date could be of advantage to high yields but a review of planting date effect on high-yielding data is not yet available. Following this rationale, a synthesis-analysis was conducted from the farmer annual maize contest-winner data (n = 16171 data points; 2011-2016 period); cordially provided by the National Corn Growers Association and a scientific lite...
During recent years, several genotypes have been selected from Isfahan land race Kouseh. The performance of safflower selected genotypes was studied in the field conditions, at Agriculture Research Station, Isfahan University of Technology during 2003. The experiment was carried out using a split plot arrangement according to a randomized complete block design with three replications. Planting ...
