“…However, results exceeding the parameters under normal conditions (without drought) were not achieved [64]. Similar results to those reported by Burondkar et al [64] were also obtained with chlorophyll and relative water content (RWC) by Singh et al [65]. Other studies on wheat under drought conditions have shown that applying chitosan nanoparticles also increases grain yield.…”

The Role of Antitranspirants in Mitigating Drought Stress in Plants of the Grass Family (Poaceae)—A Review

One of the biggest problems facing agriculture is the occurrence of droughts. Due to ongoing climate change, many regions of the world are exposed to increasingly frequent and prolonged water shortages. The situation may significantly reduce production and the quality of many crops in the Poaceae family, including crucial cereals. Therefore, it is important to find solutions that can help adapt plants to the drought phenomenon and reduce its negative effects. One measure that could potentially improve the condition of plants and help them survive under water deficit conditions is the use of antitranspirants (AT), which are products that reduce transpiration. Antitranspirants are divided into three groups: film-forming, metabolic, and reflective types. This review aimed to the current state of knowledge on the effects of selected AT applications on Poaceae plants under drought conditions. It demonstrated that AT, in many cases, mitigates the negative effects of drought on crops such as maize, wheat, or rice, which are crucial for global food security. Furthermore, AT often improved growth and yield parameters. These results are particularly relevant for countries that are important cereals producers and are more vulnerable to droughts in the future. However, it should be noted that the results obtained often depend on several factors, such as plant species, environment, type of antitranspirant, and applied dose. Therefore, it is advisable to measure further the effects of AT on plants under drought-stress conditions.

“…Hydrogel is one of the most popular gels, used to increase infiltration rates in field agriculture, in addition to increasing water holding capacity for agricultural applications (Dar and Ram, 2016) [3] . Hydrogels are cross linked polymers that can absorbed 400-1500 times their dry weight in water, due to network space created by its cross linked structure [19] . Notably, its swelling ratio increased with the rise in temperature up to 50 0 C without any adverse effect on the polymer matrix structure.…”

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.

This review presents the main findings from measurements carried out on cereals using chitosan, its derivatives, and nanoparticles. Research into the use of chitosan in agriculture is growing in popularity. Since 2000, 188 original scientific articles indexed in Web of Science, Scopus, and Google Scholar databases have been published on this topic. These have focused mainly on wheat (34.3%), maize (26.3%), and rice (24.2%). It was shown that research on other cereals such as millets and sorghum is scarce and should be expanded to better understand the impact of chitosan use. This review demonstrates that this chitosan is highly effective against the most dangerous diseases and pathogens for cereals. Furthermore, it also contributes to improving yield and chlorophyll content, as well as some plant growth parameters. Additionally, it induces excellent resistance to drought, salt, and low temperature stress and reduces their negative impact on cereals. However, further studies are needed to demonstrate the full field efficacy of chitosan.
