Production potential of wheat (Triticum astivum L.) as influenced by soil conditioners and levels of fertilizer

Field experiment were carried out during Rabi season of 2003-04 and 2004-05 at Research Farm of Shri Durga Ji Post graduate College, Chandeshwar, Azamgarh (UP) to find out the suitable soil conditioners and level of fertilizer on wheat crop. The experiment was laid out in Randomized Block Design with four replications keeping three soil conditioners viz., control, gypsum and FYM and four fertilizer doses viz., 125%RDF, 100%RDF, 75%RDF and 50%RDF. The total treatment combinations were twelve in the present field experimentations. The results revealed that the yield attributes were significantly higher with FYM application @ 5t/ha during both the years, respectively. It enhanced the grain yield to the tune of 4.21 & 2.78 and 4.01 & 2.74q/ha and straw yield 2.93 & 2.16 and 4.52 & 3.71q/ ha over control and gypsum, respectively, in respective years. The margin of 18.7 and 7.7 % in first year and 16.7 and 7.14% in second year in grain yield and in straw yield of 12.95 and 5.74% in first year and 11.4 and 5.24% in second year over 50% and 75%RDF applied, respectively. Applications of 125% RDF were statistically at par to 100% RDF and significantly higher over 75% and 50% RDF. The margin in yield of 7.66%, 7.14%, 18.7%, 16.7% and straw yield 5.74%, 5.24%, 12.95% and 11.14% over 75% and 50% of the recommended doses of fertilizer in both year, respectively. Therefore, the soil conditioners of FYM with application of 125% RDF were better production potential of wheat in present field experimentation. Keyword: Gypsum, FYM, fertilizer doses, Wheat crop
