Effect of irrigation methods and nutrient managements on productivity of late sown wheat (Triticum aestivum)

The present experiment entitled “Effect of irrigation methods and nutrient managements on productivity of late sown wheat (Triticum aestivum)” was conducted during rabi season in year 2023-24 at Instructional cum research farm, Barrister Thakur Chhedilal College of Agriculture and Research Station, Bilaspur, (C.G.). The experiment was laid out in Split Plot Design (SPD) with Irrigation methods (03): Main plot, Nutrient management (05): Sub plot treatments and three replications. The treatment consists of I1 (Surface Irrigation (Check Basin) Dept of irrigation 6 cm (IW/CPE =1), I2 (Sprinkler Irrigation (Dept of irrigation 3 cm)), I3 (Surface + Sprinkler Irrigation (Dept of irrigation 3 cm)) at Main plot: Irrigation methods and N1 (100% RDN (90:60:40 kg NPK/ha)), N2 (100% RDN through (FYM enriched by Rock Phosphate + Microbial + Consortia + Jivamrit+ Decomposer)), N3 (50% RDN through enriched FYM with microbial Consortia + 50% % RDN through FYM enriched by Rock Phosphate + Consortia + Jivamrit + decomposer), N4 (50% RDN through Urea + 25% RDN through enriched FYM with microbial Consortia + 25% RDN through FYM enriched by Rock Phosphate + Consortia + Jivamrit + decomposer), N5 (Control (No NPK)) at Sub plot: Nutrient management. The results showed at Main plot: Irrigation methods, the I3 (Surface + Sprinkler Irrigation (Dept of irrigation 3 cm)) performed the best in terms of ear length (cm), ear weight (g), number of ears plant-1, physiological maturity, number of grains ear head-1, 1000 grain weight (g), grain yield (q ha-1), biomass yield (q ha-1), harvest index, which was followed closely by the treatment I2 (sprinkler irrigation) and the lowest was observed in the treatment I1 (Surface Irrigation (Check Basin)). The results showed at Sub plot: Nutrient management, the N4 (50% RDN through Urea + 25% RDN through enriched FYM with microbial Consortia + 25% RDN through FYM enriched by Rock Phosphate + Consortia + Jivamrit + decomposer) performed the best in terms of ear length (cm), ear weight (g), number of ears plant-1, physiological maturity, number of grains ear head-1, 1000 grain weight (g), grain yield (q ha-1), biomass yield (q ha-1), harvest index, which was followed closely by the treatment N1 (100% RDN) and N2 (100% RDN through FYM enriched by Rock Phosphate + Microbial + Consortia + Jivamrit+ Decomposer) and the lowest was observed in the treatment N5 (Control).
