Effect of Different Levels of Nitrogen and Phosphorus Fertilizers on Some Properties and Productivity of Zea Mays.L (Variety Ghouta-82) in ALNashabiya Station/ Damascus Countryside Governorate

Abstract

Abstract:

This research was conducted at Al-Nashabiya Research Station of the General Commission for Agricultural Research in Damascus Countryside Governorate during the loops agricultural season for the year (2021) in order to study the effect of nitrogen and phosphorus fertilizers:(0%-50%-75%-100%-125%) of the Fertilizer recommendation on some productive characteristics of the Zea mays L of Ghouta variety 82.The experiment was developed  according to the randomized complete block design (RCBD).The results of the study showed that the treatment  was 125% moral superior in all productivity indicators (grain yield - leaf area - stem diameter - weight (100) grains),which reached  (7298.66) kg / hectare, (451.40) cm 2, (2.096) mm, (27.26) g, in the main loop respectively,and in the intensifying loop, the reached (7576.00) kg/ha, (455.60) cm2, (2.096) mm, (27.90) g, respectively.

There were no significant differences between the two treatments 100% and 75% in all indicators and in the two loops, and  the lowest value was for the studied indicators in the control treatment.
