Abstract: A field experiment was undertaken on "Scheduling of irrigation at critical growth stages of wheat under different application modes of saline water" with organic sources viz., farmyard manure (FYM) and press mud cake (PMC) for study of their effect on soil properties, nutrient uptake and yield of wheat in Sawargaon soil series. The experiment was conducted at the experimental Farm of Post Graduate Institute, Mahatma Phule Krishi Vidyapeeth, Rahuri, Dist. Ahmednagar during rabi season (1994-95). Natural water of canal water (EC 0.43 dSm-1) and well water (EC 1.78 dSm ) irrigation sources were used independently and alternatively during different critical growth stages of wheat. Results of plant analysis of flowering stage revealed that the conjunctive use of well water with canal water increased the N and K concentration as compared to canal water, well water and alternate canal + well water, whereas canal water significantly superior to all other irrigation sources in respect of P, Fe, Mn, Cu and Zn concentration in wheat at flowering stage. The wheat grain yield and straw yield were decreased with rise in electrical conductivity of irrigation waters but however alongwith organic sources it has found beneficial in increasing the yield of wheat. The canal water proved superior than well water in increasing N, Fe, Mn, Cu and Zn concentration in wheat at harvest. The alternate well + canal water increased the K concentration. The maximum reduction in nutrient uptake was observed in well water treatment. The canal water increased uptake of N, P, K, Cu, Fe, Mn and Zn. The soil analysis data revealed that the well water increased ECe, HC03~, S04 2-, Ca2+, Mg2+ and Na+ of saturation paste extract, while decreased available N, P, K, Fe, Mn and Cu content of soil. The FYM proved better than PMC in respect of available P and Mn content of soil whereas, PMC was found superior than FYM in respect of available Zn content of soil. The available N was not affected by organic sources. The canal water increased the hydraulic conductivity and aggregate stability whereas, well water increased the bulk density of soil. Organic sources helped in increasing the hydraulic conductivity. The maximum consumptive use of water was recorded under the alternate canal + well water whereas, the highest water use efficiency was found under the canal water treatments.
