تأثير التسميد العضوي والكيميائي على النمو الخضري في محصول القمحفي المناطق الجافة

Abstract

A pot experiment was conducted at Saudi Arabia during season 2005/2006 and 2006/2007 to investigate the effect of organic and inorganic fertilizer on some soil properties and yield at wheat (Triticum aestirum L.) plant ev. Yecora rojo
The plants were sown in six different treatments organic fertilizer dosage used was (10ton/ha) cattle manure chemical fertilizer dosage used was (150kg/ha) -potassium sulphate. The different treatment used as follows:
1- control 2- Urea 46% N 3-Potassium sulphate 4- Cattle manure 5-50% cattle manure + 50% Potassium sulphate. 6-50% cattle manure + 50%urea.
The treatments were arranged in complete randomized block design with four replications the growth parameters measured were plant hight number of leaves and shoot dry weight. Some soil properties also measured. more over up take of nitrogen and phosphorus were determined.
The results showed that componation of organic and chemaical fertilizer had significant effect on plant hight in the late stage of growth number of leaves and shoot dry weight in addition all growth parameters measured in this study were recorded highly compared with the chemical fertilizer.
The results also revealed that organic application had significant effect on leaves and seeds nitrogen and phosphorus content.
