TL;DR: In this paper, the authors evaluated the soil and plant water status in wheat under synthetic (transparent and black polyethylene) and organic (rice husk) mulches with limited irrigation and compared with adequate irrigation with no mulch (conventional practices by the farmers).

TL;DR: InfoCrop as discussed by the authors is a generic dynamic crop model, which provides integrated assessment of the effect of weather, variety, pests, soil and management practices on crop growth and yield, as well as on soil nitrogen and organic carbon dynamics in aerobic and anaerobic conditions, and greenhouse gas emissions.

TL;DR: In this paper, the authors established the climatically determined potential grain yields of wheat for different locations of India, to quantify the gap between actual and potential yields and to determine the optimal levels of irrigation and N required for given productivity levels.

TL;DR: In this paper, a study was conducted on PVC columns in the laboratory to investigate the effect of the application of hydrogel in modifying the hydraulic properties of different soil types, and the results of measuring soil water content (SWC) during drying revealed that in sand treated with a 0.7% gel application, the water release rates were relatively uniform throughout the entire drying period, whereas in black clay, water release rate were very high initially (4-7 DAW) but fell appreciably afterwards (less than 0.5% per day).

TL;DR: In this article, the performance of conservation agricultural technologies (like permanent narrow and broad-bed planting and residue management under zero tillage) under an irrigated cotton-wheat system in the region was evaluated.
