During the 1991 and 1992 soybean growing seasons, field plots were established in South Carolina to study the effect of planting date on at-planting nematode densities and subsequent yield losses caused by Hoplolaimus columbus. The susceptible and intolerant soybean cv. Braxton was planted on five dates from to May to 28 June in 1991 and from 12 May to 28 June in 1992. Nematodes were recovered ...

Phytophagous stink bugs are economically important pests of annual and perennial crops in the southeastern United States. Because of insecticide resistance and risk of secondary pest outbreaks, there is interest in identifying cultural practices that could lead to reduced insecticide applications. The objective of this project was to assess the importance of cotton planting date on stink bug da...

in order to assess the impact of different sowing dates on yield and yield components of wheat genotypeswith different growth habits, a two years study (2007-2009) using a split plot in randomized completeblock design with three replications was conducted in kabootarabad agricultural research station ofisfahan. three sowing dates of 12 oct., 1 nov., and 21 nov. were main plots and 15 genotypes ...

in order to determine the optimum planting date under deficit output area, this research was carried-out in 2010-11 and 2011-12 cropping seasons, in split-plot arrangement, using complete randomized block design with three replications in khuzestan agriculture and natural resource research center. main and sub plots were consisted of four planting dates (oct. 27 with 10 days interval) and four ...

Improving winter wheat water use efficiency in the North China Plain (NCP), China is essential in light of current irrigation water shortages.
