Abstract/ Executive Summary:

: Field experiments were carried out with Potato-Boro-T. aman cropping pattern at Birgonj, Dinajpur and Debigonj, Panchagarh during the consecutive years of 2011-12 to 2012-13 in the Old Himalayan Piedmont Plain Soils under agroecological zone (AEZ) 1 of North-West Bangladesh. The experiments were designed with eight treatments and laid out in randomized complete block design (RCBD) with three replications. The treatment combinations were: T1 (100%STB), T2 (T1 + 25% N), T3 (T1 + 25% NP), T4 (T1 + 25% NK), T5 (T1 + 25% PK), T6 (T1 + 25% NPK), T7 (75% of T1) and T8 (Control). Results indicated that application of different fertilizers significantly affected the grain yield at all of the locations. The highest yield was found in treatment T6 (T1 + 25% NPK). Statistically identical yield was observed in treatments T3, T4 and T5 at Birgonj, Dinajpur and T3 at Debigonj, Panchagar. All the treatment combinations gave significantly higher grain yield over the control at both of the locations. The highest straw yield was found in treatment T6 (T1 + 25% NPK). Statistically identical straw yield was found in T3 and T4 at Birgonj, Dinajpur and T1, T4 and T5 at Debigonj, Panchagarh. Significantly the lowest yield was obtained in control treatment (T8) in both of the locations. The highest total N uptake was observed in treatment T6 and a similar trend of total N uptake was observed for P uptake in both the locations. Treatment T6 showed the highest uptake of total K. The highest uptake of total S was observed in treatment T6 at Birgonj, Dinajpur and T3 at Debigonj, Panchagarh. However, the lowest total N, P, K and S uptake was observed in control treatment (T8) at both of the locations. The partial economic analysis showed the highest MBCR of 4.57 in T3 at Birgonj, Dinajpur and 4.75 in T6 treatments at Debigonj, Panchagarh respectively. Fertilizer doses recommended for Potato-Boro-T.aman pattern were N169P31K135S12Zn2B1 - N175P10K75S10Zn1B0.5 - N80P7.5K32S8 at Birgonj, Dinajpur and N188P23K169S8Zn2B1 - N188P10K94S8Zn1B0.5 - N84P7.5K40S6 at Debigonj, Panchagarh.

Objectives:

to develop fertilizer recommendation for Potato-Boro-T. aman pattern in the Old Himalayan Piedmont Plain Soils under AEZ 1.

Methodology:

Description of the experimental sites Field experiments were carried out with PotatoBoro-T. aman pattern at Birgonj, Dinajpur and Debigonj, Panchagarh during 2011-12 to 2012-13 consecutive years in the Old Himalayan Piedmont Plain Soils (AEZ 1). The climatic condition of the experimental area is sub-tropical monsoon as prevailed in the other portion of the country. The lands of the experimental areas were medium lowlands to highlands with medium to good drainage conditions. Potato-Boro- T.aman is a dominant cropping pattern although some other patterns such as Mustard-Maize-T.aman, PotatoMaize-T.aman, Wheat-Jute- T.aman, PotatoGroundnut- T.aman and Boro-Fallow- T.aman were also observed in the study areas. Collection and analysis of initial soil samples Initial soil samples were collected from the different experimental sites. After collecting soil sample, the unwanted materials like gravels, plant roots, leaves etc., were picked up and removed. Then the samples were air dried, well mixed and ground to pass through a 20 mesh sieve and stored in clean plastic bags for physical and chemical analysis. Soil samples were analyzed following standard methods Ali et al. (2013). The soils of the experimental plots were sandy loam in texture and moderately acidic in nature. The organic matter and total nitrogen contents varied from 1.20 to 1.74% and 0.060 to 0.087%, respectively. Available phosphorus and sulphur contents varied from 16.6 to 25.5 mg kg-1 and 12.0 to 21.9 mg kg-1 respectively. Exchangeable potassium content was 0.09 cmol kg-1 in both of the locations. Collection and analysis of grain and straw samples Grain and straw samples were collected during harvesting period. Grain and straw samples were dried in an oven at about 65°C for 48 hours and then ground in a grinding mill to pass through a 20 mesh sieve. The ground grain and straw samples were stored in small paper bags and placed in desiccators for the analysis of different elements. The grain and straw samples were analyzed for the determination of N, P, K and S contents following the procedures as reported by Ali et al. (2013). Details of the field experimentation The land was well prepared before transplantation. After uniformly leveling, the experimental plots were laid out in randomized complete block design (RCBD) with three replications. The unit plots area was 5mx4m. Eight treatment combinations of fertilizers were used in the experiments. The treatment combinations were: T1 (100%STB), T2 (T1 + 25% N), T3 (T1 + 25% NP), T4 (T1 + 25% NK), T5 (T1 + 25% PK), T6 (T1 + 25% NPK), T7 (75% of T1) and T8 (Control). The sources of N, P, K, S and Zn were urea, TSP, MoP, gypsum and zinc oxide, respectively. Three healthy seedlings of Binadhan-7 rice of 25-30 days old were transplanted per hill in the plots. Fertilizers were applied to each plot as per treatment. The full dose of all fertilizers except urea was applied as basal to each individual plots during final land preparation. The fertilizers were incorporated into the soils. The first split (1/3) of N was applied within 10 days after transplanting. The second split (1/3) of N was applied at maximum vegetative growth stage and incorporated with the soil. The third split (1/3) of N was applied at or before P.I. stages. Pest control and other intercultural practices like irrigation, etc. were given as and when necessary. Data on yield and yield contributing characters of different crops of the cropping pattern were recorded and statistically analyzed. Statistical analysis The recorded data were compiled and tabulated properly. The recorded data were statistically analyzed to find out the significance of variance resulting from the experimental treatments on various plant characters. Analysis of Variance (ANOVA) was done following RCBD with the help of a computer package program MSTAT and mean differences were adjudged by Duncan's Multiple Range Test (Gomez and Gomez, 1984).
