Comparison the Efficient Reclamation of Different Inorganic Materials with Organic Amendments to Rice-Wheat Crop Sustainable Production in Salt-Affected Soils

Abstract

ABSTRACT. Amelioration of salt-affected soils requires an integrated management approach, which not only improves their effectiveness for improving soil properties, but also increases the crop production and quality of the produce. Hence, a study was planned to evaluate combined use of organic and inorganic amendments for better rehabilitation of salt affected soil in ricewheat cropping sequence from 2013 to 2016. Treatments included T 1 -control, T 2 -gypsum @ 100 SGR, T 3 -CaCl 2 @ 50% SGR, T 4 -CaCl 2 @ 50% SGR + biogas slurry @ 10 tˑha for wheat (Inqlab-91) and 110-90-60 NPK kg ha -1 for rice (Shaheen Basmati) was applied. Soil samples were collected before application of amendment and after harvesting of each crop. Straw and grain/paddy yield data were recorded at maturity. Pooled data showed that grain/paddy and straw yield of wheat and rice crop was higher in T 2 (gypsum @ 100% SGR), but statistically (P≤ 0.05) non significant with T 4 (CaCl 2 @ 50% SGR + biogas slurry @ 10 tˑha -1 ). T 3 (CaCl 2 @ 50 % SGR) was at par with T 6 (H 2 SO 4 @ 25% SGR + biogas slurry @ 10 tˑha -1 ), followed by T 5 (H 2 SO 4 @ 25% SGR). The minimum yield was recorded in T 1 (control). Soil analysis showed that pH s , EC e and SAR were significantly decreased in T 2, (Gypsum @ 100% SGR), followed by T 4 (CaCl 2

Effects of Sodic Water Irrigation and Neutralizing Amendments on Physiological, Biochemical, and Nutritional Quality Traits of Fodder Sorghum

“…Hence, higher productivity (in terms of yields), profitability (GR and NR) and improved fodder quality traits (lowered NDF, ADF and HCN) in the second year. The application of different amendments might have reduced soil pH, ESP, bulk density and increased infiltration rate, hydraulic conductivity, calcium, magnesium, organic carbon and available N, which resulted in better root development, enhanced leaf area, higher photoassimilates and, thereby, more dry matter accumulation, better growth and, ultimately, productivity [20,[48][49][50][51][52]. The efficacy of gypsum and pressmud in ameliorating the adverse effects of brackish water and increasing crop yields was also reported by Choudhary et al [53] and Sheoran et al [15,[17][18][19].…”
