RESPONSE OF WHEAT (TRITICUM AESTIVUM L.) CROP TO FYM AND PHOSPHORUS FERTILIZATION UNDER SEMI-ARID CLIMATIC CONDITION

A field experiment was conducted during rabi seasons of 2011-12 at the research farm of R.B.S college, Bichpuri, Agra (UP) to assess the response of wheat (Triticum aestivum L.) crop to FYM and Phosphorus Fertilization under semi-arid climatic condition.The experiment was layout in a randomized block design with four levels of FYM (0, 2.5, 5.0 and 10 t ha -1 ) and four levels of phosphorus (0, 40, 80 and 120 kg ha -1 ) with three replications.The results revealed that the increasing dose of FYM up to 10 t ha -1 significantly, increased the grain and straw yield of wheat crop over control.But the growth and yield attributes of wheat were maximum with the application of 10 t ha -1 .Increasing level of FYM increased the yield of wheat grain and straw over control.The maximum yield of grain (3.23 t ha -1 ) and straw yield (4.30 t ha -1 ) were recorded with 10 t FYM ha -1 .The increases of grain and straw yield with this treatment were 25.48 and 19.66 % over control, respectively.The increasing levels of Phosphorus fertilizers increased the growth and yield attributes up to 120 Kg P 2 O 5 ha -1 over control.But grain and yield attributes of wheat were maximum with the application of 80 kg P 2 O 5 ha -1 .Increasing levels of Phosphorus fertilizers increased the yield of wheat grain and yield over control.The maximum yield of grain (3.33 t ha -1 ) and straw yield (4.47 t ha -1 ) were recorded with P 80 .The increases in grain and straw yield with this treatment were 28.08 and 26.63 % over control, respectively.The crop quality in respect of content and yield of wheat increased significantly with conjoint use of fertilizers and maximum values were recorded with 80 kg P 2 O 5 ha -1 and 10 t FYM ha -1 treatment.Increasing levels of FYM and Phosphorus fertilizers up to 80 kg P 2 O 5 ha -1 and 10 t FYM ha -1 also resulted in higher uptake of N, P, K and Zn by the crop and highest uptake of N, P, K and Zn by wheat crop was recorded with 80 kg P 2 O 5 ha -1 and 10 t FYM ha -1 and the lowest in control.The soil organic carbon, available N, P, K and Zn content also improved with 80 kg P 2 O 5 ha -1 and 10 t FYM ha -1 over control and lowest values of these parameters were recorded in control.
