ABSTRACT
The present investigation on effect of incorporation of crop residue on micronutrient status of soil under greengram-sunflower sequence was undertaken at Central Research Station, Dr. PDKV, Akola during 2004-05 on Vertisols particularly with montomorillonitic type with eleven treatments and three replications framed under Randomized Block Design in kharif season for greengram and split plot design in rabi season for sunflower.
The eleven treatment were T1 Control, T2 RDF greengram, T3 incorporation of cotton stalk @ 4 t ha-1 + 50% N of RDF, T4 incorporation of cotton stalk @ 4 t ha-1 + 100 % N of RDF, T5 incorporation of cotton stalk @ 4 t ha-1 + 125 % N + 100 % P through RDF, T6 incorporation of sunflower straw @ 4 t 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.
Nutrient content of nitrogen, phosphorus and potassium highest with treatment T8 incorporation of sunflower straw @ 4 t ha-1 + RDF @ (125% N + 100% P) in greengram. Content of micronutrient (Zn, Fe, Cu, Mn, B and Mo) including sulphur maximum with treatment T8 incorporation of sunflower straw @ 4 t ha-1 + RDF @ (125% N + 100% P) in greengram. Treatment T8 incorporation of sunflower straw @ 4 t ha-1 + RDF @ (125% N + 100% P) with 100 % RDF of sunflower significantly superior over 75% RDF. In relation to content of micronutrient including sulphur in rabi seasons of sunflower.
Key words :
