The research was carried out during 2009 – 2010 in Al – Hasaka – Amoda – to study the effect of cattle manure at the rate of 30 ton/h1, and four organic green fertilizers (Lentil, Vetch, Faba bean and Barely) on plant area and earliness properties of
cotton crop compared with chemical fertilizer 400 kg/h1 urea, 83 kg/h1 P2O5 and 25 kg/h1 K2O.The study showed that the cattle manure significantly increased (plant area, lower first fruiting branch, earliness of flowering and boll maturity) when compared with all studied fertilizers, the increase reached (190. 92 Cm2, 0.30 pod, 1.50 day and 0.90 day) respectively. When compared with chemical fertilizer, the legume green fertilizers (Lentil, Vetch and Faba bean) significantly increased the plant area when compared with the control. The legume green fertilizer (Lentil) significantly increased the earliness of flowering (2.73) day and boll maturity (2.21) day when compared with the green fertilizer (Barely). The chemical fertilizer did not significantly affect the earliness of flowering and boll maturity when compared with the legume green fertilizer (Lentil) during the two seasons.
The reasearch was carried out during 2009 – 2010 in Al – Hasaka – Amoda - to study
the effect of cattle manure at the rat of 30 ton / ha , and four organic green manure ( Lentil,
Vetch, Faba bean and Barely) on soil content of organic matter and so
me mineral elements
compared with chemical fertilizer 400 kg / ha urea , 83 kg / ha P2O5 and 25 kg / ha K2O .
The manure significantly increased organic matter , phosphorus and potassium
concentrations compared with other fertilizers ( chemical and green fertilizers ) . All green
fertilizers ( Lentil , Vetch , Faba bean and Barely ) significantly increased organic matter ,
nitrogen and potassium concentration compared with the control without using any
fertilizer , the tillage depth ( 0 – 10 ) cm significantly increased soil content of organic
matter and nitrogen compared with deeper tillage ( 25 – 30 ) cm during the two seasons .
