Planting Date and Residue Rate Effects on Growth, Partitioning, and Yield of Corn
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 ...

Soybean genotypes 'Cobb' (susceptible) and 'GatIR81-296' (resistant) were planted early (29May) and...
متن کاملEffect of Planting Date and Sowing Methods on Ear Yield, Water Use Efficiency and Some Physiological Characteristics of Sweet Corn
In order to investigate the effect of planting date and sowing method on ear yield, water use efficiency and some physiological characteristics of sweet corn, an experiment was carried out as a split plot based on a randomized complete block design with three replications in Yasouj, south-west of Iran. Planting date consisted of five levels (4 May, 19 May, 4 June, 19 June, 5 July) and considere...
