A field experiment was conducted during kharif 1991 -92 to 1995-96 at Sindewahi, to study the effect of incorporation of leafy foliage of glyricidia [Gliricidia sepium (J.) Walp.] with different levels of NPK on physico-chemical properties of soil and yield of rice (Oryza sativa L.). Incorporation of glyricidia leafy foliage at same site for 5 years recorded increase in organic carbon, total N, available NPK, water holding capacity and decrease in bulk density of soil over control. This treatment also recorded the significantly higher grain (52.08 q/ha) and straw (83.28 q/ha) yield over control. Amongst the fertilizer levels, application of 100 : 50 and 50 kg NPW ha recorded higher grain and straw yields over all other treatments. Maximum B : C ratio was obtained with glyricidia (5.10) followed by 100 : 50 : 50 kg NPWha (1 -40).References
