( 2013). Effect Of Compost And Compost Tea Application On Faba Bean Crop And Some Soil Biological And Chemical PropertiesJ, of Soil Sci. and Agric. Eng. Mans. Univ.Vol.4 (9):863- 874, 2013
Abstract: The objective of this investigation was to study the effect of addition of organic matter i.e, composted rice straw, compost tea and their interaction on the yield and seed nutrients content of faba bean (vicia faba L.) cv. Sakha 1 and some soil biological and chemical properties. A field experiment was conducted in the Experimental Farm of Sakha Agric. Res. Station in two successive winter seasons of 2010/2011 and 2011/2012. Results showed that soil organic matter content was increased, while values of soil salinity (ECe) were reduced and there was a slight reduction in soil pH with compost addition at rates 2 and/or 4 tons/fed. Data recorded the highest significant increases in nodule numbers and its dry weight as compared to control. Also, these treatments recorded significant increases the biological activity of soil in terms of increasing the soil total bacteria, as well as dehydrogenase activity and nitrogenase activity that increase the soil fertility, improved plant quality, as well as environmentally safe and eco-friendly, that positively turn on faba bean yield production. The interaction between compost and compost tea gave better results in increasing the seed yield especially for application of 4 tons /fed with compost tea spraying at 50 days after sowing increased the seed yield by 51%, 53.1% relative to control in the two seasons (2010/2011 and 2011/2012), respectively. Nutrients content (N, P and K) of faba bean seeds was significantly increased in all treatments compared with the control. Also, the results showed that application of rice straw compost was effective for increasing available N, P and K in soil as compared to the control. Based on the results of the current study, the combinations between rice straw compost and compost tea are considered as an integrating nutrient management to improve the soil biological and chemical properties and yield of faba bean crop.
