Abstract:
The present investigation was undertaken at Experimental Farm, Annamalai University with eleven treatments and three replications framed under Randomized Block Design in summer season for greengram and split plot design in Rabi season for sunflower. The eleven treatments were T1 Control, T2 RDF greengram, T3 incorporation of cotton stalk @ 41 ha-1 + 50% N of RDF, T4 incorporation of cotton stalk @ 41 ha-1 + 100 % N of RDF, T5 incorporation of cotton stalk @ 41 ha-1 + 125 % N + 100 % P through RDF, T6 - incorporation of sunflower straw @ 41 ha-1 + 50% N of RDF, T7 incorporation of sunflower straw @ 4 t ha-1 + 100 % N of RDF, T8 incorporation of sunflower straw @ 4 t ha-1 + 125 % N + 100% P of RDF, T9 incorporation of farm waste (including grasses) @ 4 t ha-1 + 50 % N of RDF, T10 incorporation of farm waste (including grasses) @4 t ha-1 + 100% N of RDF, T11 incorporation of farm waste (including grasses) @ 4 t ha-1 + 125 % N + 100% P of RDF. The results indicated that various physico-chemical properties of soil such as bulk density, soil reaction, Electrical conductivity were decreased available N,P,K and micronutrient status of soil were increased. It can be stated that incorporation of sunflower straw @ 4 t ha-1 + 125 % N + 100% P of RDF to greengram in kharif season and 75% RDF to sunflower in Rabi season indicating thereby 25 percent saving of fertilizers and not only improved the physico-chemical and micronutrient status of soil..
