Abstract/ Executive Summary:

To evaluate the response of wheat to N P and S fertilizers and their use economy in the production of wheat. four field experiments were cond ucted at Mymensingh, Jamalpur, Madhupur and lshurdi representing Grey Floodplain, Noncalcareous Dark Grey Floodplain. Red-Brown Terrace and Calcareous Dark Grey Floodplain soils. respectively, Effect of nitrogen was found significant in all cases. Significant response to sulphur application was recorded in Mymensingh and .Jamalpur. Responses of wheat to P application was significant in case of My.nentingh and lshurdi but insiqnlficant in case of other locations. From partial budget analysis it was indicated that the treatments NaOP12oS₄0, N120P40S40. NSOPOS₄0 and N120POS~O were economically the best treatment combinations for Mymensingh. Jamalpur, Madhupur, and lshurdi, respectively.

Program Area: Crop-Soil-Water Management

Commodity: Wheat

Objectives:

To find out suitable combination of N,P and S fertIizers for maximum economic production of wheat in different locations.

Methodology:

Four field experiments were conducted at Mymensingh. .Jarnalpur. Madhupur and Ishurdi representing Non-calcarious Dark gray floodplaln. Grey Flood plain. Red Brown Terrace and Calcare- ous Brown Floodplain Soils. respectively. The basic properties of the soils are given . The test plant used was Balaka variety of wheat in all locations except Madhupur where Sonalika variety of wheat was used. Fertilizer doses used in these experiments For Mymensingh and Jamalpur : Nitrogen@40lNI'. 80 (N2), 120,N3) and 160 N4) kg N/ha from urea; phosphorus @ 40 (PI)' 80 (P2) and 120 ,P3) kg P205/ha from TSP and sulphur @ o (So) and 40 (S I) from gypsum having factorial randornized block design. Combining the levels of fertilizers mentioned above toqsther with an absolute control treatment made the treatment number 25 which was replicated thrice. For Madhupur: Rates of nitrogen were the s ams as above: Sulphur was used @ 20 (SI', 40 (S2) and 60 (S3) kg S/ha fro n gypsum and phosphorus @ 0 (Po) and 80 (P t) kg P 20,,/ha from TS P. Nurn- bor of treatments and repl ications were also same as above. For Ishurdi: Rates of fertil izer used in this location were N @40 (N1), 80 (N2). 120 (N3), 160 N4) and 200 ~ N5) kg Njha from urea, P @ O(Po)' and 80 (PI' kg P205;ha from TSP and S @ O(So) and 40 SI) kg Stha from gypsum. N umber of treatments including an absolute control was 21 which was replicated thrice.

Achievement/Findings:

Effect of nitrogen was found significant in all cases. Significant response to sulfur application was recorded in Mymensingh and .Jamalpur. Responses of wheat to P application was significant in case of Mymensingh and lshurdi but insignificant in case of other locations. From partial budget analysis it was indicated that the treatments NaOP12oS40, N120P40S₄0. NSOPOS40 and N120POS~O were economically the best treatment combinations for Mymensingh. Jamalpur, Madhupur, and lshurdi, respectively.
