introduction determining the proper time for planting under different climate depends on the factors such as rainfall, temperature and length of day which are the most important aspects of crop production. its importance is because of the severity of these effects on different genotypes to achieve potential production. because different genotypes respond differently to planting delays. sowing d...
The experiment was conducted involving 35 rabi sorghum genotypes sown at six different dates of sowing (from Sept I week to October IV week) during 2006-07 to assess the stability for pollen fertility (%), seed setting (%) and other productivity traits viz., plant height, days to 50% flowering, number of leaves, length of panicle, panicle weight, panicle diameter, number of primaries/panicle an...
in order to evaluate the delay cropping on yield and yield component of two canola cultivars and selecting the best genotype and row spacing, an experiment was conducted at three years (2007, 2008 and 2009) in gorgan research station. this experiment was arranged in spilt-factorial based on randomized complete block design with four sowing dates (28 oct., 12 and 28 nov. and 12 dec.) as main plo...
Agronomic research suggests Australian farmers may increase wheat yields by 13 to 47% and reduce risk of crop failures by sowing crops earlier than is currently practiced. This study investigated the potential to use remote sensing to assist in evaluating changes in farmer sowing date practices in response to research recommendations, using study paddocks in the southern Australian cropping reg...
Crop depends on its canopy to intercept solar radiation to drive both assimilation and water, nutrient absorption for its growth. Field experiments, involving three sowing time and three sowing rate, were conducted at Luancheng Station to investigate the effects of canopy size and development on crop growth and radiation use efficiency (RUE) of winter wheat during 2009/2010 and 2010/2011 gr...
to study the effect of planting date, plant density and planting pattern on yield of corn (zea mays l) var. ksc 647 split plot factorial experiment in a randomized complete block design with four replications at bayranshahr lorestan province in crop year 2015 was conducted. factors examined included planting date in three levels: (25 may, 12 june and 29 june), density at three levels (60, 75 an...
in the last decade, frequency of late cold incidence has increased in the upland forest nurseries. the aim of present study was to reduce the damage caused by spring frost and to increase the efficiency of persian maple seedlings production in mountain nurseries. this study was conducted as split plot design with two main treatments and three replications in two consecutive years (2009-2010) in...
A sensitivity analysis of the responses of crops to the chosen production adaptation options under regional climate change was conducted in this study. Projections of winter wheat production for different sowing dates and cultivars were estimated for a major economic and agricultural province of China from 2021 to 2080 using the World Food Study model (WOFOST) under representative concentration...
