Interaction Effect of Organic Manures and Alkali Water on Yield of Wheat

Field experiment were carried out to investigate “Interactive effect of organic manures and residual sodium carbonate (RSC) water on yield of wheat” in rabi season (November-April) 2019-20 and 2020-21 in the Field of Agronomy, SKN Agricultural University, Jobner, Jaipur, Rajasthan, India using Split Plot Design. The treatment consists three levels of alkali water (2, 6,10 RSC mmol L-1), three organic manures (Control, FYM @15 t ha-1 and vermicompost @ 5 t ha-1) in main plot and four levels of iron (Control, 50 kg, 100 kg and 150 kg FeSO4.7H2O ha-1) in sub plot were tested with three replications. Result showed that the irrigation with 10 mmol L-1 residual sodium carbonate (RSC) water significantly decreased grain (26.02 q ha-1) and straw yield (38.15 q ha-1) of wheat in comparison to lower levels of RSC in water in wheat crop. Application of organic manures significantly increased grain yield of wheat during both the years and in pooled analysis. The highest grain (34.06 q ha-1) and straw yield (51.60 q ha-1) were obtained under vermicompost application and the effect of vermicompost (M2) and FYM (M1) application remained statistically at par with each other Interactive effect of RSC water and organic manure application on grain and straw yields of wheat was found significant and maximum being with W2 (2 mmol L-1 RSC), M2 (vermicompost @ 5 t ha-1) treatment combination indicating the magnitude of reduction in yields (grain and straw) being less with vermicompost and FYM at all the levels of RSC water.
