Abstract:

The present investigation entitled “Influence of straw mulch and nitrogen management on yield and input use efficiency of maize (Zea mays L.)” was conducted at Students’ Research Farm, Khalsa college, Amritsar. The experiment was laid out in split plot design with twelve treatments comprising of T1 : N0 + 0 t ha-1 (straw mulch); T2 : N100 + 0 t ha-1; T3 : N125 + 0 t ha-1; T4 : N150 + 0 t ha-1; T5 : N0 + 6 t ha-1; T6 : N100 + 6 t ha-1; T7 : N125 + 6 t ha-1; T8 : N150 + 6 t ha-1; T9: N0 + 10 t ha-1; T10: N100 + 10 t ha-1; T11: N125 + 10 t ha-1; T12: N150 + 10 t ha-1. The soil was sandy loam, moderately alkaline in reaction, medium in available K and available P and low in organic carbon and available N. The results showed that soil properties viz., pH and EC were not significantly affected under straw mulching treatments whereas organic carbon slightly improved through straw addition. The availability of macro nutrient (NPK) increase with increase rate of wheat straw mulch. Plant growth parameters, yield as well as nutrient uptake were highest in straw mulch as compared to no mulch treatment. Straw mulch increases the NUE (%) of maize crop. However, with increasing the rate of nitrogen, soil EC was significantly affected. The availability of macro (N, P and K) nutrient increased with increasing the rate of nitrogen fertilizer but 125 kg N ha-1 remain at par with 150 kg N ha-1. Plant growth parameters, yield as well as nutrient uptake were highest in 150 kg N ha-1 which was at par with 125 kg N ha-1.So, as by economical analysis @10 t ha-1 straw mulch and 125 kg N ha 1 will more beneficial treatment with highest B:C ratio as compared to other treatment.
