Abstract

The field experiment was carried out at Chandra Shekhar Azad University of Agriculture & Technology, Kanpur (U.P.) during Rabi season of 2020-21 and 2021-22 to study the “Influence of moisture conserving polymer and integrated nutrient management on productivity of wheat (Triticum aestivum L.) under limited irrigated condition”. The experiment comprised of twenty four treatment combinations and conducted in split plot design and replicated three times. Experiment consisted of three irrigation schedules viz. One irrigation, Two irrigations, and Three irrigations in main plots, two moisture conservation practices viz. Pusa Hydrogel 5 kg ha-1 and Paddy straw mulch 5 t ha-1 in sub plots and four nutrient management viz. 100% RDF, 100% RDF + Azotobacter, 75% RDF + Azotobacter + FYM 5 t ha-1 and 75% RDF + Azotobacter + FYM 5 t ha-1 + ZnSO4 20 kg ha-1 were kept in sub-sub plots. On pooled basis of two years experimentation result revealed that application of three irrigations at CRI, booting and milking stage resulted significant increase in the dry weight of plant, crop growth rate (CGR), phosphorus and zinc content, N, P, K and Zn uptake and protein yield in grain. Whereas, higher content of nitrogen, potash and protein in grain was recorded with one irrigation treatment. However, in moisture conservation practices higher value of all parameters as given above was recorded with the application of Pusa Hydrogel 5 kg ha-1. Among the integrated nutrient management practices, significantly higher value of N, K, Zn except phosphorus content and uptake as recorded higher with the integration of 75% RDF + Azotobacter + FYM 5 t ha-1 + ZnSO4 20 kg ha-1 but low in phosphorus.

Conclusion

It is concluded from the study that cultivation of wheat with the application of three irrigations, Pusa hydrogel and integration of 75% RDF + Azotobacter + FYM 5 t ha-1 + ZnSO4 @ 20 kg ha-1 resulted into improvement in the growth attributes, nutrient uptake and quality parameters as compared to other treatments. In limited irrigation condition, it is a viable option to use hydrogel @ 5 kg ha-1 for resources conservation in wheat cultivation.
