Effects of sowing date, nitrogenous fertilizer and insect pest control on cotton yield and its year-to-year variation in the Sudan Gezira



Effects of sowing date, nitrogenous fertilizer and insect pest control on cotton yield and its year-to-year variation in the Sudan Gezira



Journal of Agricultural Science, UK 81(3): 481-489



Variation of cotton yields from year to year has long been a major problem in the Sudan Gezira. Previous studies indicated involvement of pest attack, soil N levels and lengths of growing season in this and suggested that adequate control of these factors would lead to consistently high yields.
