The experiment was carried out at Soil Science Field Laboratory, Bangladesh Agricultural University, Mymensingh during the period from January to June, 2012. The soil belongs to Sonatala series under the AEZ-9 (Old Brahmaputra Floodplain). The soil was silt loam in texture having pH 6.18, organic matter content 2.15%, total N 0.124%, available P 6.51 ppm, exchangeable K 0.07 me%, available S 14.85 ppm and CEC 12.5 me%. BRRI dhan28, a high yielding variety of wheat was used in this experiment as test crop. The experiment was laid out in a randomized complete block design (RCBD) with three replications. The experiment containing six treatments: T0 [Control], T1 [Soil Test Basis-Chemical Fertilizer], T2 [(Cowdung) + STB-CF], T3 [(Poultry Manure) + STB-CF], T4 [(Compost) + STB-CF], and T5 [Farmer’s practice]. Here, STB= Soil Test Basis, CF=Chemical fertilizer, CD = Cowdung, PM = Poultry manure, COM= Compost, FP= Farmers’ practice, HYG= High yield goal.
Organic manures including cowdung, poultry manure and compost were applied to the experimental plots @ 5, 3 and 5 t ha-1, respectively. The recommended dozes of N, P, K and S supplied from urea, TSP, MoP and gypsum were 120, 15, 50, 15 and 2 kg ha-1, respectively. Triple super phosphate (TSP), muriate of potash (MoP), and gypsum were applied as basal dose to all the experimental plots. The amounts of nitrogen, phosphorus, potash and sulphur fertilizers required per plot were calculated as per the treatments. Cowdung, poultry manure and compost were applied before one week of transplanting (21 January, 2012). The full dose of TSP, MoP and gypsum was applied one day before transplanting (28 January, 2012). Urea was applied in 3 equal splits. The first split of urea was applied 14 days after transplanting (12 February, 2012). Second split was applied as top dressing 30 days after transplanting (29 February, 2012) and the third split of urea 45 days after transplanting i.e. at panicle initiation stage. Twenty-five days old seedlings were carefully uprooted from a seedling nursery and transplanted on 29 January 2012 on the experimental plots maintaining plant spacing of 20 cm x 20 cm. Three seedlings were transplanted in each hill. The number of rows and hills per plot was equal in all the plots. Intercultural operations such as irrigation and weeding were applied as and when necessary. The crop was harvested at full maturity. Grain yield was recorded on 14% moisture basis and straw yield on sundry basis. Five hills were randomly selected from each plot at maturity to record the yield contributing characters. Grain and straw samples were analyzed for NPKS consents following standard methods. The NPKS uptake by grain and straw was calculated from their contents and yield data. All the data were statistically analyzed by F-test and the mean differences were ranked by DMRT at 5% level.
