Abstract

A field experiment was conducted during rabi 2020-21 and 2021-22 at Agriculture research farm, RNTU, Raisen, entitled “Effect of irrigation scheduling and integrated nutrient management on soil moisture, water productively and soil fertility”. The treatments combination consists of two factors such as irrigation scheduling and integrated nutrient management practices. The treatment were: Factor A: Irrigation scheduling (I0-CRI, late, Jointing, and milking stage, I1-CRI, late jointing, flowering and milking stage, I2-Irrigation with (0.8 IW/CPE) and I3-Irrigation with (1.0 IW/CPE) and Factor B: Integrated nutrient management practices (F0-100% RDF+ZnSO4 30 kg, F1-75% RDF +25% RDN through FYM+ZnSO4 25 kg/ha, F2-50% RDF+50% RDN through FYM +ZnSO4 20 kg/ha and F3-100 kg+25% RDN through FYM+ZnSO4 15 kg/ha). The experiment was laid out in split plot design with three replications. The results revealed that the irrigation levels and nutrient management treatments did not influence significant variation on moisture content at sowing of wheat crop during both the years of experiment (2020-21 and 2021-22). Significant difference was observed with irrigation levels on water use efficiency (13.16 and 13.21 kg/ha/mm) and water productivity (1.74 and 1.39 kg/m3) in wheat during 2020-21 and 2021-22, respectively. Application of F3 gave highest water use efficiency (10.14 and 9.88 kg/ha/mm) and water productivity (1.66 and 1.12 kg/m3) which was significantly superior over other treatments. The highest available nitrogen of 96.48 and 97.28 kg/ha and phosphorus of 55.23 and 57.29 kg/ha during 2020-21 and 2021-22 were recorded with I0. Potassium was maximum (421.54 and 419.65 kg/ha during 2020-21 and 2021-22, respectively) under the treatment I2 (Irrigation with 0.8 IW/CPE). Among fertility grades, maximum available nitrogen of 112.89 and 114.67 kg/ha were recorded under the treatment F0 (100% RDF + ZnSO4 30 kg) and maximum phosphorus of 56.68 and 57.12 kg/ha were recorded under the treatment F1 (75% RDF + 25% RDN through FYM + ZnSO4 25kg/ha) during 2020-21 and 2021-22. However, the maximum potassium was recorded under F2 (50% RDF + 50% RDN through FYM + ZnSO4 20 kg/ha) in 2020-21 and F3 (100 kg + 25% RDN through FYM + ZnSO4 15 kg/ha) in 2021-22.

Conclusion

Based on two year of experimentation, the irrigation at CRI, late, Jointing, and milking stage in wheat was obtained superior for WUE, water productivity and available N and P. Application of 50% RDF+50% RDN through FYM +ZnSO4 20 kg/ha recorded the maximum WUE and water productivity. However, the maximum available nitrogen was recorded under the treatment F0 (100% RDF+ZnSO4 30 kg) and maximum phosphorus was recorded under the treatment F1 (75% RDF +25% RDN through FYM+ZnSO4 25 kg/ha).
