In full season of wheat,wheat stripe rust was controlled about incidence of 28.02 %-65.5 % by the intercrop of wheat/barley or wheat /faba bean,and mixed planting of different wheat varieties.
Grid soil sampling and VR P and lime application were done prior to four crops over 3 years: full season soybean, wheat (Triticum aestivum L.)-double cropped soybean, and full season soybean.
These observations support the use of a previous full season or summer oat crop jointly with chisel plowing, plus the prevention of excessive traffic during secondary tillage and planting, to reduce common root rot in a field infested with A.
Grain sorghum can substitute for corn as a full season crop and replace soybeans in double cropping systems with wheat in the southeastern United States.
Proper early sowing to let soybean to have "full season" development can increase LAI andaccumulate biological yield of soybean. Under proper early sowing condition first flowering ap-pears earlier and appearance of last flower is postponed, and flowering season is then prolorged,yield then increases significantly.
Spraying methomyl 20 EC at the rate of 900ml/ha in cotton fields to control the cotton bollworms of the second generaton,the degraded rates of methomyl in cotton leaf after seven days and in soil after fourteen days of application were respectively 98.81% and 88.09%,and the half-lives of degradation were 1.56 days and 4.98 days respectively.After 6 times of application with total 1080g of active ingredient of methomyl per ha.in cotton's full-season, the maximum residues in cotton seed and soil w...
This study used four varieties (strain) of full season Upland cotton (FSC) breeded in South Xinjiang and five series of varieties in cotton research institute of China, that were introduced and extended to Xinjiang. They were crossed in an incomplete dialled design to analyze the combining ability and genetic ability of thirteen economic characters. The results indicated that, single boll weight, the first branch height of varieties (strain) breeded in South Xinjiang were mainly controlled by a...
