“…The higher water requirements coupled with greater evapo-transpiration under FI resulted in less water productivity ( Table 8 ). Ghazanfar et al. (2010) explained that the significant increase in applied water under FI could be due to the higher evaporation during the growing period, while the sprinkler irrigation minimizes evaporation losses from the soil and from crop canopy surface and also applying irrigation based on crop water needs (ETc) improved WUE of soybean under Spr 60% ETc ( Kang et al., 2014 ; Gajic et al., 2018 ; Uddin and Murphy, 2020 ; Djaman et al., 2022 ).…”

Sensor-based decision tools provide a quick assessment of nutritional and physiological health status of crop, thereby enhancing the crop productivity. Therefore, a 2-year field study was undertaken with precision nutrient and irrigation management under system of crop intensification (SCI) to understand the applicability of sensor-based decision tools in improving the physiological performance, water productivity, and seed yield of soybean crop. The experiment consisted of three irrigation regimes [I1: standard flood irrigation at 50% depletion of available soil moisture (DASM) (FI), I2: sprinkler irrigation at 80% ETC (crop evapo-transpiration) (Spr 80% ETC), and I3: sprinkler irrigation at 60% ETC (Spr 60% ETC)] assigned in main plots, with five precision nutrient management (PNM) practices{PNM1-[SCI protocol], PNM2-[RDF, recommended dose of fertilizer: basal dose incorporated (50% N, full dose of P and K)], PNM3-[RDF: basal dose point placement (BDP) (50% N, full dose of P and K)], PNM4-[75% RDF: BDP (50% N, full dose of P and K)] and PNM5-[50% RDF: BDP (50% N, full P and K)]} assigned in sub-plots using a split-plot design with three replications. The remaining 50% N was top-dressed through SPAD assistance for all the PNM practices. Results showed that the adoption of Spr 80% ETC resulted in an increment of 25.6%, 17.6%, 35.4%, and 17.5% in net-photosynthetic rate (Pn), transpiration rate (Tr), stomatal conductance (Gs), and intercellular CO2 concentration (Ci), respectively, over FI. Among PNM plots, adoption of PNM3 resulted in a significant (p=0.05) improvement in photosynthetic characters like Pn (15.69 µ mol CO2 m−2 s−1), Tr (7.03 m mol H2O m−2 s−1), Gs (0.175 µmol CO2 mol−1 year−1), and Ci (271.7 mol H2O m2 s−1). Enhancement in SPAD (27% and 30%) and normalized difference vegetation index (NDVI) (42% and 52%) values were observed with nitrogen (N) top dressing through SPAD-guided nutrient management, helped enhance crop growth indices, coupled with better dry matter partitioning and interception of sunlight. Canopy temperature depression (CTD) in soybean reduced by 3.09–4.66°C due to adoption of sprinkler irrigation. Likewise, Spr 60% ETc recorded highest irrigation water productivity (1.08 kg ha−1 m−3). However, economic water productivity (27.5 INR ha−1 m−3) and water-use efficiency (7.6 kg ha−1 mm−1 day−1) of soybean got enhanced under Spr 80% ETc over conventional cultivation. Multiple correlation and PCA showed a positive correlation between physiological, growth, and yield parameters of soybean. Concurrently, the adoption of Spr 80% ETC with PNM3 recorded significantly higher grain yield (2.63 t ha−1) and biological yield (8.37 t ha−1) over other combinations. Thus, the performance of SCI protocols under sprinkler irrigation was found to be superior over conventional practices. Hence, integrating SCI with sensor-based precision nutrient and irrigation management could be a viable option for enhancing the crop productivity and enhance the resource-use efficiency in soybean under similar agro-ecological regions.

“…The results revealed that it is possible to limit the amount of applied irrigation water, when there is a water shortage, by using alternative irrigation method. The data also showed that irrigation water applied under NT was higher than CT. Ghazanfar et al (2010) explained that the significant increase in applied water under NT may be due to the higher evaporation during the growing period. The highest water applied was accompanied with the highest consumptive use obtained with FI treatments, which consumed more water than SI and AI treatments.…”

FIELD study was carried out during two growing seasons of 2012/2013 and 2013/2014 at the Water Requirements Research Station, Water Management Research Institute, Kafer El-Sheikh Governorate to compare two irrigation methods, surge (SI) and alternate (AI) with traditional furrow irrigation method (FI) in relation to two tillage systems, conventional (CT) and no-tillage (NT) on water use efficiency and crop yield production of soybean. In both seasons, the lowest amount of irrigation water was applied with AI treatments, whereas, the highest amount of irrigation water was applied with FI treatments. The irrigation water amounts were saved by using AI and SI methods. The AI and SI saved about 29.0 % and 15.0 % of water applied in comparison with FI under CT and NT systems. Irrigation water productivity (IWP) and crop water use efficiency (CWUE) were higher when applying AI compared to SI and FI under both tillage systems. Surge irrigation had the potential to improve irrigation application efficiency (AE) followed by AI compared to FI. The highest seed yield and yield attributes were obtained with FI followed by SI and AI in both seasons, respectively. Significant differences in seed yield, yield attributes and plant growth characteristics were found only between FI and AI under CT and NT. The SI surpasses the AI in obtaining higher seed yield, yield attributes without any significant reduction of soybean yield. These results suggesting that an extra irrigation water amount may be saved without any significant loss in yield of soybean when applying SI method under both tillage systems. The results also showed the effect of CT on reducing applied water and increasing irrigation water productivity and crop water consumptive use compared to NT. However, no significant difference between the two tillage systems in yield and yield attributes was found. Values of ETc should be adjusted according to the used irrigation and tillage methods. The crop water stress index (CWSI) has proven to be a good indicator for monitoring and quantifying water stress of soybean with different irrigation methods and tillage systems.

Two field experiments were conduct at the Experimental site with the help of agriculture research Centre Sriganganagar Rajasthan, during season 2020-2021and 2021-2022 to study the effect of chemical nitrogen rate (0, 30, 60 kg N/fed.) and compost rates application (0,1.5, 3 ton /fed.) and its interaction on productivity of the wheat Raj-3077 and soil properties. Treatments were arranged in split plot design with three replicates (the main plots included chemical nitrogen. while, compost rates were allocated at the sub plots). The results revealed that increasing chemical nitrogen rates from 0 to 60 kg N/fed. significantly increased plant dry weight/m2, plant height, number of tillers and spikes/m2, number of grains /spike, weight of 1000-grain, grain and straw yield/ fed. and grain protein content in both seasons. Application of 60 kg N/fed. recorded the highest values for all previous studied traits compared with untreated plants (control treatment) which gave the lowest values. compost rates recorded significant differences for all studied traits of wheat as plant dry weight/m2, leaf area index, plant height, number of tillers and spikes/m2, number of grains/spike, weight of 1000-grains, grain yield, straw yield and grain protein content in both seasons except for dry weight in the first season; The application of 3 t/fed. recorded the greatest significant values for all previous studied traits compared with the untreated control treatment which showed the lowest values. The interaction between chemical nitrogen and compost rates application had a significant effect on plant dry weight/m2, leaf area index, plant height, number of tillers and spikes/m2, number of grains /spike, weight of 1000-grains, grain and straw yield in both seasons, with exception of plant dry weight/m2 in the first season and the grain protein content in both seasons. Application of 60 kg N/fed. + 3 t compost /fed. gave the highest significant value of plant height, number of tillers and spikes/ m2, weight of 1000 grain and grain yield/fed. without significant differences between them. The highest significant values of grain yield in both seasons and straw yield in the second season were achieved by 60 kg N/fed. + 3 t compost /fed. followed by 30 kg N/fed. + 1.5 t compost /fed. Soil salinity (ECe) and saturation hydraulic conductivity (Ks) as well as available N, P, and K in the soil were significantly increased with increasing N rates applied generally up to 60 kg N/fed., while soil pH and bulk density (ρa) were not significantly affected in the two seasons. Saturation hydraulic conductivity (Ks) as well as available N, P, and K in the soil were significantly increased with increasing compost rate applied generally up to 3 ton/fed., while soil salinity, pH and bulk density were significantly decreased in the two seasons Finally, adding compost at rate of 3 t/fed. resulting in the improvement of soil properties. From the results and under the conditions of this study, it could be concluded that application of 60 kg N/fed. combined with compost at rate 3 t/fed producing the highest grain and straw yields.
