Growth and chemical properties of maize grains of some single crosses as affected by nitrogen and manure fertilization under sprinkler irrigation in sandy soil

Abstract: Two field experiments were conducted at ismailia agricultural research station in 2000 and 2001 season to study the performance of three hybrids,two white single crosses (SC10 and SC 122)and a yellow single cross(SC 155) UNDER THREE NITROGEN RATES,45,90 AND 135KGN/FED AND TWO RATES OF ORGANIC MANURE,0 AND 20M/fed increasingN rates significantly deceased number of days to 50%tasseling and silking.plant height,ear position,number of green leaves and number of ears/plant were increased significantly by increasing N rates up to.135kN/fed. some chemical properties(Ash%,protein,total carbohydrate.amylose,amylopectin percentage and carotenoid content of maize kernels were affected by increasing nitrogen fertilizer rates from 45 kgN/fed up to 135kgN/fed.
Application of 20m manure/fedsignificantly decreased number of days to 50% tasseling and silking.plant height and number of green leaves were increased significantly by the addition of farm yard manure.percent of ash,protein and total carbohydrate were affected by the addition of 20m fym/fed. yard manure significantly affected amylose,amylopectin, oil and carotenoid content of maize grain.nitrogen x manure interactions were significant for plant height and ear position. nitrogen x hybrids interactions were significant for number of days to 50% taasseling and silking,plant height and ear position. manure x hybrids interactions were significant for silking , plant height and ear position. manure x hybrids interactions were significant for silking date,plant height and number of green leaves.
