“…Super absorbent polymer increasing the capacity of water storage in soil (El-Hady and Wanas, 2006) and through reduction of water evaporation from the surface of soil (Akhter et al, 2004). Polyacrylamides in soil were also able to reduce the amount of water loss from soil through evaporation ( Abdel-Nasser et al, 2007). Huttermann et al (1999) reported that hydrogel application at highest rate (0.4%) changed the water retention and its change in water potential with regard to its water content from typical sand to a loam or even silty clay.…”

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.

“…Biochar, a soil conditioner that is produced from the pyrolysis of crop residue and biomass, has been widely reported to improve soil hydro-physical and chemical properties such as soil water holding capacity and hydraulic conductivity [12][13][14][15]. It also improves the retention of soil nutrients [16].…”

The deficit irrigation strategy is a well-known approach to optimize crop water use through the estimation of crop water use efficiency (CWUE). However, studies that comprehensively reported the prediction of crop evapotranspiration (ETc) and CWUE under deficit irrigation for improved water resources planning are scarce. The objective of the study is to predict seasonal ETc and CWUE of maize using multiple linear regression (MLR) and artificial neural network (ANN) models under two scenarios, i.e., (1) when only climatic parameters are considered and (2) when combining crop parameter(s) with climatic data in amended soil. Three consecutive field experimentations were carried out with biochar applied at rates of 0, 3, 6, 10 and 20 t/ha, while inorganic fertilizer was applied at rates of 0 and 300 Kg/ha, under three water regimes: 100% Full Irrigation Treatment (FIT), 80% and 60% FIT. Seasonal ETc was determined using the soil water balance method, while growth data were monitored weekly. The CWUE under each treatment was also estimated and modelled. The MLR and ANN models were developed, and their evaluations showed that the ANN model was satisfactory for the predictions of both ETc and CWUE under all soil water conditions and scenarios. However, the MLR model without crop data was poor in predicting CWUE under extreme soil water conditions (60% FIT). The coefficient of determination (R2) increased from 0.03 to 0.67, while root mean-square error (RMSE) decreased from 4.07 to 1.98 mm after the inclusion of crop data. The model evaluation suggests that using a simple model such as MLR, crop water productivity could be accurately predicted under different soil and water management conditions.

“…So, application of sulphur and micronutrients to the plants are an important practice in sustaining agricultural productivity, especially in clayey soil. The effect of sulphur on some characteristics of soil as well as plant growth was discussed by many workers such as Abdel-Nasser et al (2007) who concoluded that soil conditioners i.e., natural deposits significantly increased the water constants of soils (i.e., FC, WP and AW). Deshbhratar et al (2010) reported that applying elemental sulphur is an important practice in sustaining soil fertility and agricultural productivity, especially in clayey soil.…”

A field experiment was carried out on winter season 2012 / 2013 with wheat (Bani swif 1) grown on a clayey soil at Sids Agric. Res. Station to study the effect of sulphur (S) application and micronutrients (Mi) i.e. Fe, Zn, Mn and Cu on some properties of soil and available macronutrients in soil as well as the grain and straw yields of wheat and they chemical composition. Sulphur was added at rates of 0, 250, 500 and 1000 kg /fed alone or with afore named micronutrients which sprayed at the rate of 0.1 % Fe in the form of chelated (6%), 0.05 % Zn in the form of chelated (14 %), 0.05 % Mn in the form of chelated (13 %) and CuSO 4 at rate of 1 g / L. The experiment was conducted in a randomized complete block design with 4 replicates. The obtained results showed that the values of soil moisture retention (field capacity, wilting point and available water) were increased with increasing sulphur addition. The available contents of NPK in soil were increased with S application alone , and these increases were more pronounced when micronutrients were added. The highest treatment was found to be a mixture of 1000 kg S + Mi. This treatment reflected its positive effect on the grain and straw yields of wheat, where the highest increasing percent in the grain and straw yields of wheat reached 15.02 and 20.80 %, respectively. Data also indicated that addition of S with Mi to the studied clayey soil markedly increased the contents of NPK in wheat grains and straw, particularly at the highest rate of sulphur and Mi. On the other hand, application of S at rate of 500 kg /fed beside sprayed with Mi gave the best treatment for all the previous parameters, because there no big differenc between 1000 kg S /fed + Mi and 500 kg S /fed + Mi or not significant.
