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 ...

field experiments were conducted in amirkabir sugarcane agro-industry (khuzestan province, iran) farms to evaluate the efficacy of integrated chemical and mechanical methods in controlling weeds. experiments were carried out in a split plot-randomized complete blocks design with four replications. the main plot consisted of four mechanical treatments, namely: hilling up, sweep cultivator, disc ...

in order to study the effects of planting systems on quantitative and qualitative characteristics of some onion genotypes, an experiment was conducted in a split plot arrangement in randomized complete block design with three replications in behbahan agriculture research station for two years (2012-2014). in this study two planting systems: onion set and transplant were assigned to main plots a...

Microplot experiments were conducted to evaluate the effects of inoculum level and time of application of Paecilomyces lilacinus on the protection of tomato against MeIoidogyne incognita. The best protection against M. incognita was attained with 10 and 20 g of fungus-infested wheat kernels per microplot which resulted in a threefold and fourfold increase in tomato yield, respectively, compared...

Results We present global planting date patterns for maize, spring wheat and winter wheat (our full, publicly available data set contains planting and harvesting dates for 19 major crops). Maize planting in the northern mid-latitudes generally occurs in April and May. Daily average air temperatures are usually c. 12–17 °C at the time of maize planting in these regions, although soil moisture of...
