“…Drilling hydrogel (2.5 kg/ha) along with foliar application of either NPK (0.5%) or salicylic acid (75 ppm) helps in increasing the yield of lentil [5]. Thus, hydrogels have pronounced prospective in areas under limited opportunity for irrigation and can increase the water use potential during crop establishment stages, besides improving soil physical-chemical properties [17,18].…”

Lentil (Lens culinaris) is an important winter season annual legume crop known for its highly valued seed in human and animal nutrition owing to its high lysine and tryptophan content. Shortage of water during the crop growth period has become the major impediment for cultivation of pulses in rice fallow in particular. Under such conditions, the application of hydrogel can be a potential alternative to improve photosynthetic efficiency, assimilate partitioning, and increase growth and yield. A field experiment was conducted from November to February during 2015–16 to 2017–18 on clay loam soil that was medium in fertility and acidic in reaction (pH 5.4) at Central Agricultural University, Imphal, Manipur. The experiment was laid out in split plot design with three replications. There were three hydrogel levels in total in the main plot and foliar nutrition with five different nutrient sprays in sub-plots, together comprising 15 treatment combinations. The data pooled over three years, 2015–2018, revealed that application of hydrogel at 5 kg/ha before sowing recorded a significantly greater number of pods per plant (38.0) and seed yield (1032.1 kg/ha) over the control. Foliar application of nutrients over flower initiation and pod development had a positive effect on increasing the number of pods per plant eventually enhanced the seed yield of lentil. Foliar application of either 0.5% NPK or salicylic acid 75 ppm spray at flower initiation and pod development stages recorded significantly more pods per plant over other nutrient treatments. Further, the yield attributed improved because of elevated growth in plant. Significantly maximum seed yield (956 kg/ha) recorded in the NPK spray of 0.5% remained on par with salicylic acid 75 ppm (939 kg/ha) over the rest of the treatments.

“…The gel mitigates the risks, if the water availability drops. Two irrigations in wheat can be saved by application of hydrogel without compromising the grain yield (Roy et al, 2019) [17] . Keeping these points in mind, the present investigation was carried out to examine the influence of Pusa and Herbal hydrogel on growth, yield attributes, yield and economics of wheat under different irrigation levels.…”

A field experiment was carried out during Rabi season of 2016-17 and 2017-18 at CCS Haryana Agricultural University, Hisar (Lat. 29°10' N, Log. 75°46' E and 215.2 m amsl) to investigate the effect of irrigation levels and hydrogels on the growth, yield and profitability of wheat. The soil of the field was sandy loam in texture, slightly alkaline in pH (7.9), low in organic carbon, poor in available nitrogen and medium in available phosphorus and available potassium. The experiment was laid out in split plot design with four irrigation levels viz., no irrigation (control), three irrigations at crown root initiation (CRI), late tillering (LT) and grain filling (GF) stage, three irrigations at 35/40 days after sowing (DAS), 80 and 120 DAS and six irrigations at critical stages i.e. CRI, tillering, jointing, flowering, milking and dough stage in main plot and three moisture conservation practices viz. control (no hydrogel), Pusa Hydrogel @ 2.5 kg/ha and Herbal Hydrogel (Gum Tragacantha i.e. Goond katira) seed treatment in subplots, replicated thrice. Pooled results of two consecutive year, 2016-17 and 2017-18 revealed that progressive increase in wheat grain yield and biological yield was recorded with every increment in irrigation frequency. Six irrigations brought significantly higher grain yield (62.11 q/ha) over no irrigation (36.94 q/ha), three irrigation at CRI, LT and GF (52.90 q/ha) and three irrigations at 35/40, 80 and 120 DAS (55.87 q/ha). Maximum grain yield in six irrigated crop might be due to significantly more growth and yield attributes viz., plant height (100.94 cm), effective tillers/m 2 (406.67), grains/earhead (59.43) and 1000-grain weight (39.53 g) in six irrigated crop then other irrigation regimes. Six irrigated crop produced 40.52, 14.83 and 10.05% more grain yield than control, three irrigation at CRI, LT and GF stage and three irrigation at 40, 80 and 120 DAS. Among different moisture conservation treatments, the application of Pusa hydrogel and herbal hydrogel had not improved grain yield of wheat significantly as compared to control (without hydrogel). Although Pusa Hydrogel treatment produced numerically higher grain yield (52.55 q/ha) and yield attributes then control (51.31 q/ha) and Herbal Hydrogel (52.01 q/ha). Application of six irrigation at all important crop growth stages provided additional gross return (Rs. 53001/ha) and net returns (Rs. 45688/ha) over without irrigation. The highest grain yield was recorded when six irrigations were applied at all the critical growth stages and application of Pusa hydrogel and herbal hydrogel had not improved grain yield of wheat.

To improve the soil moisture availability, by reducing the evaporation losses and retaining the moisture in effective rooting zone. The soil application of superabsorbent polymers (SAPs) is found to be the promising methodology in drought prone areas. However, very limited research work done in Indian conditions on this aspect. One of such successfully developed product is ‘Pusa hydrogel’ which is first indigenous semi-synthetic superabsorbent technology for conserving water and enhancing crop productivity and thereby increases the water use efficiency. It performs its wetting or drying cycles over a longer period of time, maintaining its very high water swelling and releasing capacity against soil pressure. Consequently evaporation, deep water percolation and nutrient leaching can be avoided. Under rainfed condition, crops can better withstand drought condition without moisture stress by using hydrogel. Systematic field studies under arid and semi-arid conditions of India are needed to develop appropriate dose, frequency and method of application of different polymers to various crops and to assess economics of use of different polymers.
