“…Similar findings were reported regarding spike length effects in wheat (Swati et al, 1985;Ahmad, 1994;. Optimal moisture levels due to irrigation at CATD of -1 °C maximized grains per spike, consistent with Islam et al (1990), Shrief et al (2015), and Verma et al, 2023. Different wheat genotypes have shown variable grain counts per spike (40 to 59) in various studies (Musaddique et al, 2000;Patel, 2016;Goher et al, 2023).…”

This study addresses efficient water usage in wheat cultivation in a semi-arid region of India with clay loam soil and an increasing water supply-demand gap. It focuses on optimizing drip irrigation (DI) scheduling, of wheat crops, based on canopy air temperature difference (CATD) using the crop water stress index (CWSI). The field experiments were conducted for two winter seasons, employing high-discharge drip irrigation (DI) on wheat crop (variety - GW 366) at Junagadh Agricultural University (JAU), Gujarat, India. The experiment had nine treatments, each replicated three times in randomized blocks. The DI treatments labeled as T1 to T6, were irrigated at CATD values of -4, -3, -2, -1, 0, and 1 °C, respectively.. While T7 were irrigated by border irrigation. In order to define upper and lower baselines of CWSI, well watered treatments (T8) and extreme dry treatment (T9) DI were considered. The drip irrigation system (DIS) had an application rate of 7.78 mm/h with a uniformity coefficient of 90.40%. Compared to surface irrigation, DI resulted in water savings ranging from 3.52% (T1) to 43.24% (T6). Using real-time CATD data, the theoretical CWSI (CWSITh) and the vapor pressure deficit (VPD) based semi-empirical CWSI (CWSIVPD) were calculated as 0.3351 and 0.3668, respectively. CATD values showed significant variation in CWSI across treatments. The CWSI demonstrated sensitivity to water stress during critical growth stages. The study identified an optimal CATD of -1 °C, yielding 36.48% higher crop yield (4744 kg/ha), 30.23% water savings (388.42 mm), and notable 95.67% more water use efficiency (12.21 kg/ha-mm,), surpassing the outcomes of border irrigation (3476 kg/ha, 556.74 mm and 6.24 kg/ha-mm). These findings hold significant implications for farmers and policymakers, effectively addressing food and water security concerns. The study underscores the efficiency of DI combined with CATD-based irrigation scheduling in optimizing wheat crop performance. In the context of critical water management, this research provides essential insights for sustainable agricultural practices.

Wheat is a key cereal crop that is substantial to global food security. Fertilizers are crucial in wheat production and significantly impact the yield. This review aims to evaluate the effectiveness of inorganic, organic, and integrated fertilizers in terms of sustainable wheat production and economic and environmental benefits. For this review, we thoroughly examined 133 previous research findings. The results indicate that inorganic fertilizers play a vital role in improving wheat yield. However, continuous use of inorganic fertilizers pollutes the environment, affects beneficial microorganisms in the soil, and increases the emissions of greenhouse gases, consequently decreasing crop yield. Organic fertilizers enhance soil quality, which is critical for crop growth and development. However, a high concentration of methane (CH4), nitrous oxide (N2O), and carbon dioxide (CO2) are emitted from organic fertilizers, but the CO2 emission rate is less than the sequestration rate. Integrated fertilizers trade off the drawbacks of both inorganic and organic fertilizers. Integrated fertilizers decrease nitrous oxide (N2O) and ammonia (NH3) emissions and carbon loss by 11%–24%, 13%–27%, and 18%, respectively, compared to the sole use of fertilizers. From the review analysis, the highest grain yield (4855 kg ha−1) and net benefit ($2836.66) are achieved by using a combination of 75% organic and 25% inorganic fertilizers at a rate of 120 kg N ha−1. Therefore, this combination is recommended for the users. Furthermore, a site‐specific approach research is needed on integrated fertilizers that simultaneously focus on economic and environmental profits. Also, there must be a policy that supports the farmers in teaching, training, and subsidizing them to adopt integrated fertilizers for sustainable wheat production and improving food security.
