The greatest challenge to Indian agriculture in the twenty-first century appears to be water
scarcity. According to estimates from the Central Water Commission, more than 54% of the
nation is at risk of drought. India has 4% of the world's freshwater resources, with the
agricultural sector using more than 85% of it. Water availability per person is steadily
declining, which highlights the necessity of improving water use efficiency in agriculture. The
usage of Super Absorbent Polymers (SAPs) has recently attracted a lot of interest for
agricultural water management. These polymers have the ability to swell 350–500 times of
their own weight in deionized water, and they have the capacity to produce more with less
water. Additionally, bioagents (Trichoderma), organic manures (FYM and compost) have the
ability to release of nutrients from soil or increase organic matter content, thus improving water
retention capacity and maintaining the health of the soil.
Methodology
The field experiment was conducted under Varanasi condition of eastern Uttar Pradesh during
the rabi (winter) season of 2016-2017 at the Agricultural Research Farm, Institute of
Agricultural Sciences, Banaras Hindu University, Varanasi, Uttar Pradesh (India). The soil of
the experimental field was sandy clay loam in texture with 0.35 % organic carbon. The
experiment was laid out in randomized block design with 4 replications. HUW -510 variety of
wheat was selected for the experiment. The experiment comprised of 7 treatments of different
combinations of hydrogel, Trichoderma, FYM, D18 Compost and recommended doses of
NPK.
Results
The maximum number of ear heads/running m was obtained with combined application of NPK
+ FYM, which remained at par with FYM + Hydrogel + NPK and D 18 Compost + NPK, while
