EFFECT OF APPLICATION METHODS OF WHEAT REASIDUSE EXTRACT AND N P K LEVELS ON YIELD AND SOME GROWTH PROPERTIES OF Vicia faba L.

Abstract

A Plastic pots experiment was conducted in replacement position (abo greab) of Anbar University in department of soil sciences and water resources, college of agriculture, in the season 2016 in a silty clay loam soil , To investigate the influence of application methods of the wheat straw compost extract (control, soil application foliar application , and soil application+ foliar application ) and NPK levels 0, 50 and 100% from fertilizer recommendation , using (RCBD) design with three replication on some properties of faba plants growth and yield. Results showed that most application method s of the compost extract caused a significant increases in most of parameters used and mix application (land+foliar) has surpass in plant height, number of branches ,shoot dry weight, root dry weight, weight of 100 grains, grain yield, fertilization efficiency 60.46 cm ,13.89 branch.plant-1, 14.20, gm.plant-1 , 5.13, gm plant-1, 238.9 gm , 233.2 gm pot -1 43.0% , respectively. fertilizer level caused in a significant increases in all above parameters and the level 100% from fertilizer recommendation gave the highest results at the number of branches ,shoot dry weight, root dry weight, weight of 100 grains, grain yield, fertilization efficiency 14.67 branch plant-1, 14.65, gm plant-1 , 5.13, gm plant-1, 238.2 gm , 233.2 gm pot -1 54.7% , respectively. The interaction between of the study factors were significant and the mix application method combined with the 100% from fertilizer recommendation achieved highest increase the number of branches ,shoot dry weight, weight of 100 grains, grain yield, fertilization efficiency 15.67 branch plant-1, 15.70 gm plant-1 , 254.8 gm , 244.0 gm pot -1 62.0% , respectively.
