| Abstract | ||||
| Two field experiments were carried out at Gemmeiza Agricultural Research Station farm during 2000 and 2001 seasons to evaluate Ihe effect of nitrogen zinc and boron on chtorophyll content grain yield and Its components as well as stover yield of maize plant (lee mays. L.) C.v. Sc 10 . The most important results can be surnmartzed as follows :- 1- Chlorophyll a.o , total chlorophyll content. yield components . (i. e . ear length. ear weight. ear grains weight. number of grains and row. 100 - grain weight. number . of ears I fed, ear yield ton I (ed ., grain yield ton I fed. and stover yield ton I fed.) were I significantly increased by increasing rate of N - fertilizer up to 120 kg N I fed. 2· Increasing nitrogen fertilizer rates up to 120 kg N I fed. significantly increased nitrogen concentration and its uptake as well as proteln content . 3· Phosphorus and Potassium concentrations and its uptake were significantly increased by applying 120 kg N J fed. 4- Zinc application at 20 kg zinc sulphate 1 fed. showed significant increase in values of ear weighl . ear grains weight, number of grains I row. number of ears I fed . ear yield ton I fed .. chlorophyll a.b, Phosphorus and Potassium concentration and its uptake. Application of 10 kg zinc sulphate I fed increased nitrogen concentration and its uptake as well as protein content. 5- The effect of foliar boron application was nOI significant with the sludied characters except number of ears I fed .slover , yield in the first season and number of ears I fed .• in Ihe second one. as weJl as N .P . k concentration and its uptake. From the aforementioned results it can be concluded that ,for high yield production of maize nitrogen fertilizer and zinc sulphate must be applied at 120kg N and 20kg zinc sulphate/feo. | ||||
