Changes in Calcareous Soil Activity, Nutrient Availability, and Corn Productivity Due to The Integrated Effect of Straw Mulch and Irrigation Regimes

Sustainable agricultural production is mainly attributed to healthy soils. Calcareous soils, especially in arid and semiarid areas, suffer from low organic matter nutrient availability. Low could degrade soil with reducing the crop productivity. Thus, present study aimed assess integrated effect of mulch irrigation on activity, availability, potentiality corn yield under calcareous conditions. In a soil, two mulching treatments (mulch non-mulch) as well three regimes, applied ratio evapotranspiration (60, 80, 100%, denoted I60, I80, I100, respectively), were arranged strip plot design based completely randomized block arrangement using 3 replicates. Mulching plus by I80 achieved maximum increases carbon, matter, activity. Higher values NH4+–N form detected non-mulch I100 or I60. Lower Zn content was obtained due I100. With lowering level 20% (I80) application mulch, weight ear, 100 kernels, kernel amounted 5.4, 4.6, 16.1%, respectively. Results conclude that adoption system moderate (80% evapotranspiration) considered promising management practice for amending saving water, sustaining/boosting productivity zones.
