INTEGRATING BLACK CUMIN WITH GROUNDNUT IN THE SANGU RIVER BASIN OF BANDARBAN HILL DISTRICT

The experiment was conducted at the farmers’ field in the Sangu River basin under the On-Farm Research Division, BARI, Bandarban, during the rabi season of 2020-21 and 2021-22 to determine the suitability of incorporating black cumin at varying geometry under groundnut intercropping system. The treatments were T1: sole groundnut (farmers’ practice), T2: sole black cumin, T3: one row of black cumin in between two normal rows of groundnut, and T4: paired row of black cumin in between two normal rows of groundnut. Treatments were arranged in a randomized complete block design with three replications. Between intercropped treatments, a double row of black cumin within two normal rows of groundnut (T4) showed higher groundnut equivalent yield (3.79 t ha-1), gross return (Tk. 219330 ha-1), gross margin (Tk. 157145 ha-1) and benefit-cost ratio (3.53) followed by T3, with groundnut equivalent yield, gross return, gross margin and BCR of 3.40 t ha-1, Tk. 201867 ha-1, Tk. 141330 ha-1 and 3.33, respectively, over the respective sole groundnut (2.82 t ha-1, Tk. 171498 ha-1, Tk. 113978 ha-1 and 2.98 respectively). The lowest groundnut equivalent yield was obtained from sole black cumin (2.35 t ha-1) with a lower gross margin of Tk. 82192 ha-1. All competition functions to assess the efficacy of the intercropping system also justified the compatibility of black cumin with groundnut as a profitable practice in the Bandarban region.

Performance and Possibility of Growing Wheat Varieties in Chalan Beel Area

The experiment was conducted at Dobila, Tarash of Shirajgonj in Chalan Beel during rabi season of 2016-17 and 2017-18. The treatments were four wheat varieties viz. ‘BARI Gom-25’, ‘BARI Gom-26’, ‘BARI Gom-28’ and ‘BARI Gom-30’. Wheat var. ‘BARI Gom-30’ produced the highest grain yield (5.02 t/ha in 2016-17 and 4.83 t/ha in 2017-18 with pooled value of 4.93 t/ha) associated with higher number of spikes/m2 (372-444/m2 with pooled value of 408/m2) and higher number of grains/spike (pooled value of 45/spike). ‘BARI Gom-30’ required field duration of 113 days. Two years’ results revealed that ‘BARI Gom-30’ performed better in Chalan Beel area in respect of higher mean grain yield (4.93 t/ha) and economics (Gross margin of Tk.100400/ha and BCR of 1.78). There was no blast infestation in the experimental field in both the years. Farmers showed moderate interest to grow wheat in Chalan Beel area specially in upland (medium low land of Beel) condition. Among the wheat variety ‘BARI Gom-30’ could be suitable for cultivation in Chalan Beel area.

Functioning of Rice Bran Market in Kishoreganj District, Bangladesh: Focused on Market Structure, Conduct and Performance

The commercial rice bran industry in Bangladesh has experienced remarkable growth in the last decade and it continues to grow. However, lack of a wellcoordinated marketing system of agriculture products remains a major constraint in further development of the industry. The focus of the study, therefore, was to assess the structure, conduct and performance of the rice bran market in Kishoreganj district in order to elucidate the performance of the marketing system before any interventions are made to change the existing conditions. The data for the study was sourced from both primary and secondary sources. The study employed descriptive statistics and Gini coefficient to determine the degree of rice bran market concentration in the study area. The gross margin, marketing margin and marketing efficiency was used to measure the performance of the rice bran market in Kishoreganj district. The results of the study showed that the Gini coefficient was 0.495 and 0.493 for wholesalers and retailers respectively, indicating a highly concentrated market hence an oligopoly market structure. The conduct of the market participants, which reflects the behavior of the firms or the decision that firms make relating to their pricing and output policy and other competitive practices, revealed that among rice miller, the two forms of terms of sale were contract selling 10 percent and spot market selling 90 percent. Further, the study found that rice miller attained the highest gross margin of TK 191,000 followed by wholesalers and retailers with TK 10,300 and TK 3,100 respectively. The marketing margin revealed that retailers attained the highest marketing margin of 11 percent while wholesalers had 10 percent. In conclusion, rice bran production and trading in Kishoreganj district is profitable but not to a satisfactory state due to lack of collusive behavior among market participants and availability of market information. The study, therefore, recommends that the Government of Bangladesh should integrated agricultural marketing information system which is linked to rice millers, wholesalers, retailers and final farmers in order to avoid exploitation of high prices.

Planting System Effects on Intercropping of Gardenpea and Sorghum

The field experiment was conducted at Agronomy Research Field, Joydebpur and RARS, Burirhat, Rangpur, BARI during Rabi season of 2018-2019 and 2019-2020 to find out suitable combination of sorghum and gardenpea intercropping for higher productivity and monetary advantage. Treatments included in the experiment were: T1 = Sorghum normal row (SNR) + 1 row gardenpea (GP), T2 = SNR + 2 rows GP, T3 = Sorghum paired row (SPR) + 2 rows GP, T4 = SPR + 3 rows GP, T5 = SPR + 4 rows GP, T6 = Sole sorghum (60 cm ´ 10 cm) and T7 = Sole GP (30 cm ´ 10 cm). Light availability on gardenpea decreased with the increase of shade produced by sorghum canopy over the time up to 60 DAS. The lowest light availability on gardenpea was observed in T2 treatment and the highest was observed in sole gardenpea (T7) followed by T3 treatment in both the years. The maximum grain yield of sorghum was observed in T6 and it was decreased (6-10% in 2018-2019 and 1-12% in 2019-2020) at Joydebpur and (5-11% in 2018-2019 and 6-14% in 2019-2020) at Burirhat. The highest sorghum equivalent yield (SEY) of 10.93 t ha-1 in 2018-2019 and 12.02 t ha-1 in 2019-2020 at Joydebpur and 12.06 t ha-1 in 2018-2019 and 11.77 t ha-1 in 2019-2020 at Burirhat and also the highest land equivalent ratio (LER) of 1.77 in 2018-2019 and 1.93 in 2019-2020 at Joydebpur and 1.79 in 2018-2019 and 1.81 in 2019-2020 at Burirhatwere observed in T5 treatment. The highest gross margin of Tk.146600 ha-1 in 2018-2019 and Tk.168400 ha-1 in 2019-2020 at Joydebpur and Tk. 169200 ha-1 in 2018-2019 and Tk.163400 ha-1 in 2019-2020 at Burirhat and also the benefit cost ratio (BCR) of 3.04 in 2018-2019 and 3.34 in 2019-2020 at Joydebpur and 3.35 in 2018-2019 and 3.27 in 2019-2020 at Burirhat were also found in the same treatment. The results revealed that sorghum paired row + 4 rows gardenpea might be agronomically feasible and economically profitable for sorghum + gardenpea intercropping system at Joydebpur and Burirhat region.

Value chain analysis of sunflower in coastal areas of Amtali upazila of Barguna district

Sunflower is an important oil seed crop which is well fitted in Robi season of the coastal areas of Bangladesh. This study focused on sunflower value chain map, value addition, value chain governance and institutional linkages, and stakeholders and their roles and responsibilities in value adding process of sunflower. A total of 60 respondents were interviewed by using pretested questionnaire. A combination of purposive and snowball sampling techniques was used to select the respondents. Descriptive analytical technique was used to achieve the objectives. The study found that farmers were hardly engaged in sunflower marketing activities. The value chain map comprised of collectors/assemblers, processors, wholesalers and retailers. On an average, total costs (production and marketing) incurred by the farmers were Tk. 11,986.30/acre (100 decimals) of sunflower. Assemblers received a total gross margin of Tk. 588/100 kg of sunflower seeds. At wholesale node the total gross margin was found to be Tk. 209/100kg of sunflower seeds. It was observed that processor received gross margin of Tk. 878. The processors were the pivotal point for the sunflower oil in the study area. The findings revealed that 40% of the total sunflower seed productions were sold by farmers to chain actors in while the remaining 60% was left for own consumption. It was also found that there was certain arrangements of producers and traders in case of production and marketing of sunflower. The main business challenge in sunflower production is scarcity of quality seed and the marketing challenge is fluctuation of prices. Thus, policy should be guided to supply quality seeds and maintain the stable price of sunflower.

Effect of Seed Rate and Walkway on Yield of Field Pea Under Relay Cropping with T. Aman Rice

The field experiment was conducted at Pulses Research Centre (PRC), Ishurdi, Pabna and Regional Agricultural Research Station (RARS), Jamalpur during rabi 2012-2013 to find out the effect of seed rate and walkway for green pea production as relay cropping with transplanted Aman rice. The experiment was based on six seed rates @ 50, 60, 70, 80, 90 and 100 kg ha-1 and two walking ways viz. 15 cm wide walkway at 2 m interval over the plot and control with three replications. A local cultivar of pea, named Natore was used in this trial. Results revealed that the treatment with 100 kg seed ha-1 gave the highest pod yield of 5.13 t ha-1 and 4.98 t ha-1 at Jamalpur and Ishurdi locations, respectively which was similar to 80 (S4) and 90 (S5) kg seed ha-1.. Walkway had no significant variation in yield and yield contributing characters but it produced the higher yield over the control. Using walkway, 100 kg seed ha-1 (S6) and 15 cm walkway at 2 m interval over the plot (W1) produced the highest pod yield of 5.14 t ha-1 and 4.95 t ha-1 and fodder yield of 6.70 t ha-1 and 6.13 t ha-1 at Jamalpur and Ishurdi locations, respectively. Maximum gross margin of Tk. 1,06,040 ha-1 and Tk. 1,02,401 ha-1 was contributed by combinations of using 100 kg seed ha-1 and 15 cm walking way but maximum benefit cost ratio (BCR) of 3.40 and 3.43 were obtained from S5×W1 combination at Jamalpur and Ishurdi locations, respectively. It is concluded that pea cultivar can be successfully cultivated for green pod production through the use of 90-100 kg ha-1 seed with walkway of 15 cm wide in the plot after 2 m intervals.

Gross Margin and Factor Analysis of Watermelon Production in Patuakhali District, Bangladesh

This study examined the Gross margin and factor productivity of watermelon production in Patuakhali district, Bangladesh. A multi-stage stratified sampling design had been used for the selection of the watermelon growing farmers. Data were obtained with the aid of a pre-tested structured questionnaire. The socio-economic characteristics of the respondents was described and categorized by Descriptive statistics, Gross margin analysis was used to analyze the cost and returns to watermelon production and Cobb Douglas production function was used to evaluate the input factor productivity. Results showed that the farmers are relatively middle-aged with an average age of 41 years with a sizable number of the respondents (1.7%) having passed through tertiary education. It was also observed that the farmers are typically smallholders with an average farm size of 50-249 decimal. The result of the gross margin analysis showed that watermelon production is profitable with a gross margin of Tk 756 per decimal. The result of the Cobb Douglas production function shows that the coefficients of cost of seed (0.137), cost of tillage (0.227), cost of irrigation (0.304), cost of labour (0.156), and cost of pesticide (0.305) were positively significant at 5% and 1%. The overall factor productivity index is 1.19 implying an increasing return to scale in water melon production in the study area. However, lack of irrigation facility and pesticide were identified as major production constraints.

AbstractThe experiment was conducted at the Regional Agricultural Research Station, BARI, Ishwardi, Pabna, Bangladesh, during 2013-2014 and 2014-2015 to introduce maize as relay crop with T. Aman rice under different agronomic practices for determine the production potentials. The experiment was design split plot with three replications. The agronomic management practices included four plant spacing viz. S1=75 cm×20 cm (66666 plants/ha), S2=60 cm×20 cm (83333 plants/ha), S3=50 cm×20 cm (100000 plants/ha) and S4=40 cm×20 cm (125000 plants/ha) and four soil management practices viz. M1=soil mulching at 25 DAE, M2=earthing up at 25 DAE, M3=straw mulching at 25 DAE and M4= without earthing up and mulching (control). Seeds were relayed by dibbling manually in 10 days before the harvest of T. Aman rice. Results showed that an increasing plant spacing increased leaf area Index (LAI), total dry matter (TDM), crop growth rate (CGR) and light energy interception (LEI). Grain yield was higher in S3spacing (8.44 t/ha) than others (S48.11 t/ha, S27.34 t/ha and S16.89 t/ha). Among the soil management practices, M2increased LAI, TDM, CGR, LEI as well as grain yield. Moreover, M2and M1gave similar grain yield (8.22 t/ha and 8.02 t/ha), that were significantly greater than other two soil management practices (M37.55 t/ha and M46.98 t/ha). From the economic point of view, combination of S3M1gave better performance with gross margin of Tk. 95000/ha and BCR of 2.17. On the basis of results, S3M1combination was suitable for growing maize under relay sowing with T. Aman rice.

The study was conducted at Dingapota Haor under Mohongonj Upazila in Netrakona District during April 2011 to March 2012 to examine the profitability of individual farming systems namely crop-livestock-poultry–fishcatching (C-LP- FC), crop-livestock-fish catching-labour selling (C-L-FC-LS), fish catching– labour selling (FC-LS), crop-livestock (C-L), crop-livestock-fish catching (C-L-FC) and crop-livestock-poultry (C-L-P). A total of 60 farm households under six farming systems were selected that analyzed the level of input used in different enterprises. The results showed that the highest net return of C-L-FC farming system was Tk. 119214 and lowest for C-L-P farming system which was Tk. 25131.The estimated total costs of C-L-P-FC, C-L-FC-LS, C-L, C-L-FC and C-L-P farming systems were Tk. 287959, 304430, 62316, 255624, 322654 and Tk. 241354 respectively. Again for C-L-P-FC, C-L-FC-LS, FC-LS and C-L farming systems, the net returns were Tk. 66238, 107578, 74673 and 42967 respectively. Among the farming systems, C-L-FC produced the highest gross margin of Tk. 424859 and CL- P produced the lowest which was Tk. 266486. The benefit cost ratio of all the farming systems was more than 1 which indicates that all of these were profitable. The gross margin, net return and BCR for C-L-FC farming system was reasonably high and the system earned positive management income indicating that the farming systems were economically viable even under all possible full cost assumptions.

Effect of Presprouting of Seeds on Field Duration of Short and Long Duration Potato Varieties in Haor Ecosystem

A field experiment was conducted at the farmers’ field of Livelihood Improvement of Farming Community in Haor Area through System Approach Project site Purbo Tethulia, Mohangonj, Netrakona during the Rabi Season of 2011-2012 to shorten the field duration of potato through seed pre-sprouting technique and to find out the suitable potato variety for cultivation in Dingaputa haor area without affecting the cultivation period of boro rice. Diamont and one local variety Challisha were taken for the study. Pre-sprouting duration of Diamont was 10, 20, 30 and 40 days with un-sprouted Diamont and Challisha. In the study unsprouted Diamont produced significantly the highest yield (25.28 tha-1) followed by 20.01, 13.46, 13.31, 12.74 and 11.54 tha-1 of 10, 20, 30, 40 days pre-spouted Diamont and un-sprouted Challisha, respectively. The lowest field duration of the crop was 41 days of 30 and 40 days pre-spouted Diamont. The highest gross margin of Tk.165960 ha-1 was observed from the unsprouted Diamont potato against the variable cost of Tk.137400 ha-1 incurred. The performance of Challisha was also appreciated by the farmers for its quality and low cost of production. Unsprouted Diamont potato also ranked the top most position in terms of benefit cost ratio of 2.21.DOI: http://dx.doi.org/10.3329/jesnr.v5i2.14815 J. Environ.

Profitability of BARI Released Potato (Solanum tuberosum L.) Varieties in Some Selected Locations of Bangladesh

Potato is one of the important food crops in Bangladesh. Its demand is increasing day by day. The Tuber Crop Research Centre (TCRC) of BARI released 40 HYV potato varieties and disseminated them in the farmer’s fields through different agencies. But most varieties were not adopted well by the farmers due to unknown reasons. Therefore, an attempt was made to assess the level of adoption and profitability of BARI released potato variety at farm level. Data were collected from 150 randomly selected potato farmers from Munshigonj, Bogra and Comilla districts during January-February 2010. The results indicated that 48% potato areas were covered by Diamant variety, 16% by Cardinal, 22% by Granola, and the rest 14% areas were covered by Binella, Asterix, Provento, Felsina, Multa and Hira. The cost of BARI released potato cultivation was Tk 2, 10,629 and Tk 1, 84,135 per hectare on full cost and variable cost basis. The major share of total cost was for seed (42%) followed by fertilizer (21%) and human labour (14%). The average yield of potato was 26 t/ha with gross margin of Tk 1, 51,003 per hectare. The net return of potato cultivation was Tk 1, 24,509 per hectare. The benefit cost ratios were 1.59 and 1.82 on full cost and variable cost basis. Human labour, land preparation, seed, and irrigation had positive and significant effect on potato production. Nonavailability of HYV seed at proper time, lack of technical knowledge, high price of seed and fertilizer, infestation of insect and diseases, and lack of storage facilities were the major problems of potato production.

Socio-economic assessment of wheat variety Shatabdi in some selected areas of Bangladesh

The survey was conducted in two villages under Dinajpur and Thakurgaon Districts during March 2004 to assess the socioeconomic aspects of Shatabdi wheat variety adoption at farm level. Stratified random sampling technique was followed for farmer selection. All categories of farmers expected wheat varieties having high yielding potentialities with less disease and pest infestation, more heat tolerant, and bold grain with golden colour. New wheat variety Shatabdi is able to meet the maximum expected characters. Old variety Kanchan was more disease susceptible and new one was free from disease. A significant yield difference was found between new and old verities (Shatabdi yielded 3l% to 43% higher compared to Kanchan over the locations and farmers group). Gross margin (return over variable cost) of Shatabdi also higher compared to Kanchan. By cultivating new variety, farmers earned additional gross margin of Tk. 6446 to Tk. 8353 per hectare in Jagdal and Tk. 6097 to Tk. 9314 per hectare in Daulatpur over Kanchan. Cent percent farmers over the locations said that their income was increased by cultivating Shatabdi compared to old variety Kanchan. The non-adopter farmers wanted new variety seeds. All groups of farmers wanted training/video show for up-dating their technical know how. Key Words: New vs old varieties; profitability level; farmers' adoption.

Effect of seed treatment and foliar spray with fungicides in controlling black point disease of wheat

The efficacy of seed treatment and foliar spray with fungicides in controlling black point incidence of wheat seeds was evaluated in the field. Two seed treating fungicides, namely Vitavax-200 and Homai-80WP were used @ 0.25% of dry seed weight and foliar spray with Tilt-250EC (0.05%) was applied in six different schedules. Untreated and unsprayed controls were also maintained. Seed treatment with either Vitavax-200 or Homai-80WP significantly increased plant population and grain yield, but none of them was found effective in reducing black point incidence. On the other hand, foliar sprays with Tilt-250EC under all the spray schedules except spraying at 70 and 90 DAS significantly minimized the disease severity over unsprayed control. Among the different spray schedules, spraying at 30, 40, 50, 60, 70, 80, and 90 DAS appeared to be most effective, which was similar to spraying at 30, 45, 60, 75, and 90 DAS in reducing black point incidence and increasing grain yield. Economic analysis on yield advantage showed that the highest additional gross margin of Tk. 6120/ha with BCR 2.57 was obtained from five sprays applied at 30, 45, 60, 75, and 90 DAS. Key Words: Seed treatment, foliar spray, black point, wheat. DOI: 10.3329/bjar.v34i3.3968 Bangladesh J. Agril. Res. 34(3) : 425-434, September 2009

Response of garlic to zinc, boron and poultry manure application

Response of garlic (var. BARI Garlic-2) to zinc, boron, and poultry manure application along with a blanket dose of 150 kg N, 50 kg P, 100 kg K, and 40 kg S/ha was evaluated through field trials in the Grey Terrace Soil under AEZ 25 (Level Barind Tract) at Spices Research Centre, Bogra during two consecutive rahi seasons (2005-2006 and 2006-2007). Application of zinc, boron, and poultry manure significantly had increased plant height, number of leaves/plant, cloves/bulb, diameter, and weight of bulb and yield/ha in both years. The highest bulb yields of 6.10 t/ha in 2005-2006 and 6.23 t/ha in 2006-2007 were obtained from the Zn5B1 kg/ha plus 5 t/ha poultry manure treatment and it was significantly higher over all other treatments. Next to it, the treatment Zn5B1 kg/ha plus 2.5 t/ha poultry manure gave the highest bulb yield (5.99 t/ha in 2005-2006 and 6.00 t/ha in 2006-2007). The highest gross margin of Tk. 230594/ha in 2005-2006 and Tk. 234095/ha in 2006-2007 along with lower marginal rate of return (65 and 163%) were obtained with Zn5B1 kg/ha plus 5 t/ha poultry manure treatment. This treatment was not economical because of the higher cost involvement. Application of Zn at 5 kg/ha along with blanket dose of N, P, K, and S fertilizers would be profitable (MRR of 5650% in 2005-2006 and 1562% in 2006- 2007) for garlic cultivation in the Gray Terrace Soil of Shibgonj, Bogra.

Impacts of sulphur levels on yield, storability and economic return of onion

The experiments were carried out at the Regional Agricultural Research Station, Rahmatpur, Barisal during the rabi seasons of 2001-2002 and 2002-2003 to study the impact of different sulphur levels on bulb yield, storability and economic return of onion. Sulphur application had significant effect on yield components and bulb yield of onion. The highest bulb yields (19.75 and 19.88 t/ha) were obtained from sulphur levels between 60 and 75 kg/ha in two consecutive years. Both the cumulative weight and rotten loss were significantly influenced by sulphur fertilization. The maximum weight loss (40.78%) was recorded after 180 days of storage in S60 kg/ha and the minimum (31.40%) was found in S45 kg/ha. The bulbs stored in bamboo platform were found in acceptable condition after 6 months of storage showing 31.40% of weight loss. The maximum rotten bulbs (63.75%) were observed in control treatment (without S) and the minimum rotten bulbs (37.04%) were observed in S45 kg/ha after 180 days of storage because application of sulphur enhanced the storability of onion bulbs. The highest (9146 %) marginal rate of return (MRR) with gross margin of Tk. 181844/ha was obtained from the sulphur level S60 kg/ha. Key Words: Sulphur, yield, storability, economic return, onion. doi: 10.3329/bjar.v33i4.2286 Bangladesh J. Agril. Res. 33(4) : 539-548, December 2008

Effect of N, P, K and Cowdung on the Growth and Yield of Panchamukhi Kachu (<i>Colocasia esculenta</i> var. <i>esculenta</i> Schott.)

A field experiment was carried out during two consecutive cropping seasons of 2001-02 and 2002-03 at the Agricultural Research Station, Raikhali, Rangamati, to optimize fertilizer need for desirable yield of Panchamukhi Kachu (Colocasia esculenta var. esculenta Schott.). Fourteen combinations of treatments consisting four levels of N (0, 50, 100 and 150 kg/ha), five levels of P2O5 (0, 25, 50, 75 and 100 kg/ha), four levels of K2O (0, 60, 120 and 180 kg/ha) and three levels of cowdung (0, 10, 20 and 30 t/ha) were tested. A positive impact of each nutrient and cowdung application was observed on vegetative growth and fresh yield of the crop. The highest yield (average of two years) of 35.20 t/ha (54% increase over control) was obtained with the application of 100 kg of N, 75kg P2O5, 180 kg, K2O and 10t cowdung/ha. From the economic point of view, the combination of 100 kg of N, 75kg P2O5, 180 kg K2O and 10 ton cowdung/ha was found to be the most suitable one which offered a gross return and gross margin of TK. 3.25 lakh/ha and Tk. 3.39 lakh/ha, respectively coupled with marginal rate of return as high as 3530.77%.

Response of Different Levels of Nitrogen and Phosphorus on the Growth and Yield of French Bean

Afield experiment on French bean was conducted in Old Brahmaputra Floodplain Soil of Jamalpur and Grey Terrace Soil of Joydebpur during 2005-2006 to find out the optimum rates of N and P for yield maximization. Four levels of nitrogen (0, 100, 150 and 200 kg ha-1) and 3 levels of phosphorus (0, 40 and 60 kg ha-1) were used in the experiment. Potassium (K) 80 kg, sulphur (S) 10 kg and 5 t cowdung ha-1 were applied as a basal dose. The experiment was laid out in a randomized complete block design with 12 treatments replicated 4 times. Nitrogen and phosphorus alone significantly influenced the pod yield of French bean. Among the N levels, the highest pod yield (13.33 t ha-1 at Jamalpur and 14.68 t ha-1 at Joydebpur) were obtained with 150 kg N ha-1. Among the P levels, the highest pod yield (12.35 t ha-1 at Jamalpur and 13.69 t ha-1 at Joydebpur) were obtained with 60 kg P ha-1. Interaction effect was not significant. However, highest pod yield (13.60 t ha-1 at Jamalpur and 15.05 t h-1 at Joydebpur) was obtained from 150 kg N plus 60 kg P ha-1. Economic analysis showed that 150 kg N plus 40 kg P ha-1 gave the highest gross margin of Tk. 1,66,684/ha.
