“…This may be due to the fact that application of hydrogel and salicylic acid at variable doses when applied at different intervals resulted in significant effects on the rainfall use efficiency as well as cumulative water use (Table 2). Similar findings were reported by Meena & co-workers [9]. However, lowest seed yield and yield attributes were recorded in control plots (T1) during both the years of experimentation.…”

Aims: To study the effect of salicylic acid and hydrogel on water use efficiency and productivity of Indian mustard in Jammu. Study Design: Randomized Block Design (RBD). Place and Duration of Study: Oilseed Experimental Area, Research Farm, SKUAST-Jammu, Chatha, Jammu & Kashmir (UT). Methodology: The field experiment was conducted during the rabi season of 2014-15 and 2015-16 at the Research Farm, Chatha of the Sher-e-Kashmir University of Agricultural Sciences and Technology of Jammu which is situated at 320 40’ N latitude and 740 58’ E longitude with an altitude of 332 m above mean sea level. The experiment comprised of nine treatments with 3 replications. Results: The application of Salicylic acid @ 200 ppm at flowering and siliquae formation stage in combination with use of hydrogel @ 2.5 kg/ha resulted in increase in the yield attributes, and seed yield of Indian mustard besides concomitant increase in the rainfall water use efficiency and cumulative water use of Indian mustard and was found to be the most economical treatment than other treatments in comparison. Conclusion: Based on average of two years of experimentation, application of Hydrogel @ 2.5 kg/ha + Salicylic acid 200 ppm at flowering stage & siliquae stage with maximum average benefit: cost ratio may be recommended for mitigation of moisture stress in Jammu region for obtaining higher crop yield, better rainfall water use efficiency, cumulative water use and profitability due to better average economic returns (2.50) in rainfed areas of Jammu region.

“…The treatment hydrogel 5 kg/ha + SA 200 ppm spray at flowering and siliqua formation stage produced significantly higher number of siliqua per plant (305.00 and 308.67) compared with other treatments in both the years. The positive effect of hydrogel and SA on number of siliquae per plant in Brassica crop also was reported by Meena et al (2020). Pusa hydrogel have the capacity to retain water 300-400 times of its weight and its gradual release helps to maintain soil moisture till the maturity which provide enough time for siliqua formation and seed filling under less frequent irrigation (Shim et al 2008).…”

“…Among different combination of hydrogel and salicylic acid, a significant height (177.33 and 178.00 cm) was obtained with treatments H @ 5 kg/ha + SA 200 ppm spray at flowering and siliqua formation which was significantly higher than other treatments during both the years. This may be ascribed that soil application of hydrogel improving the soil moisture availability and foliar spray of SA mitigate the drought stress and induces more auxin production which improves the cell elongation and cell development of plant even in unfavourable climatic condition (Meena 2020).…”

A field experiment was conducted during winter (rabi) season of 2017-18 at Varanasi to evaluate the effects of hydrogel as Super Absorbent Polymer (SAP) and salicylic acid (SA) as stress-ameliorating agent, in growth and productivity of Indian mustard (Brassica juncea L.) at rainfed condition. The experiment comprised nine treatments such as Control (T1), Hydrogel (H) @ 2.5 kg/ha (T2), H @ 5 kg/ha (T3), SA 100 ppm (T4), Salicylic acid (SA) 200 ppm (T5), H @ 2.5 kg/ha+ SA 100 ppm (T6), H @ 2.5 kg/ha+ SA 200 ppm (T7), H @ 5 kg/ha+ SA 100 ppm (T8), and H @ 5 kg/ha+ SA 200 ppm (T9). Among the different treatments, soil application of H @ 5 kg/ha and foliar spray of SA@ 200 ppm registered the highest value (mean of two year) of plant height (177.66 cm), primary (7.37) and secondary branches (7.74), siliqua/plant (306.84) as well as maximum seed yield (18.02 q/ha) and straw yield (2344.09 kg/ha). Exogeneous spray of SA alone with higher dose performed better in all parameters than individual application of hydrogel, however, their combination also gave superior result in minimizing moisture stress in plant.

Background and Objective: Owing to swelling properties and easy fabrication, hydrogels are employed intensively in agricultural applications. Nano-particles were used in agriculture due to their high surface area and reactivity in soil. This study aims to improve the adsorption capacity of soil from nutrients and enhance water holding capacity using hydrogel grafted with magnetic nanoparticles. Materials and Methods: Herein, hydrogel composite of acrylic acid or sodium acrylate co-polymer cross-linked with magnetic nanoparticle (HG-MNP) were synthesized and characterized by FTIR, TGA, BET and TEM techniques as compared with the hydrogel (HG). A pot experiment was conducted to evaluate the effects of HG and HG-MNP on crop productivity, quality and water-use efficiency of eggplant under different irrigation and mineral fertigation doses. Results: The results indicated that the incorporation of magnetic nanoparticles (MNP) into the hydrogel matrix can significantly improve both the thermal stability and the swelling ratio of the hydrogel samples. The results of the pot experiment conducted on eggplant treated with the modified HG showed a significant increase in the studied morphological characteristics including plant high, stem diameter, number of branches, leaves, fruits, chlorophyll concentrations and crop yield compared to the control. This was attributed to the higher swelling ratio of HG-MNP and the higher adsorption ratios of nutrients than HG, which ensured an adequate supply of water and nutrients throughout the growth period of the crop. Conclusion: These results indicated that the integration of HG-MNP is beneficial for agricultural applications, especially under water stress.
