Effects of Organic Waste and Clean Salt Treatment on Reducing Irrigation Water Salinity, Selected Soil Properties, and Wheat Yield

Abstract

Background: Saline irrigation limits wheat production, so the feasibility of organic amendments and commercial treatments to improve soil conditions and crop performance are being explored. Objective: To evaluate the effects of irrigation salinity, organic waste and Clean Salt on soil properties and wheat plant performance, single and combined levels of these factors. Methodology: The experiment involved a completely randomized factorial with three irrigation salinities, four poultry–buffalo manure rates, three Clean Salt rates and five replications. Factorial ANOVA and LSD comparison were used to assess the effect of postharvest soil properties and plant traits. Results: Higher application of organic waste resulted in statistical reduction in soil electrical conductivity, and also increased the thousand grain weight, shoot dry weight along with the number of tillering. Use of Clean Salt resulted in a reduction in mean conductivity from 5.38 to 4.81 dS m−1. Maximums in grain weight, shoot biomass, and tillering occurred with the highest rates of combined amendments under 3 dS m−1 irrigation. Thousand-grain weight, shoot biomass and tillers per plant had corresponding maximums of 46.00 g, 36.37 g plant−1 and 8.33 tillers per plant, respectively. The post-harvest pH values were found to be in the range of 7.00–7.40 and increased slightly with the amendment application rates. The soil conductivity elevated in the salinity levels and the plant response was maximum at intermediate soil salinity. Conclusion: Although some salinity management is demonstrated by the combined amendments, field verification and measurements of salt balance are needed for any levels of recommendation for application or claim of desalination.
