In this context, four popular sweet potato varieties (viz., ‘BARI Mistialu-8′, ‘BARI Mistialu-12′, ‘BARI Mistialu-14′, and ‘BARI Mistialu-15′) were used in the study. These varieties were released by Bangladesh Agricultural Research Institute (BARI). In the first season (2018–2019), these varieties were evaluated at nine locations, and in the second season (2019–2020), the same varieties were tested further, but only in three locations. The trial was set up in a randomized complete block design and repeated three times. After two years of observation, it was found that the fresh root yield was varied significantly due to the environment (E), genotypes (G), and their (G × E) interaction (p ≤ 0.01) by using genotype and genotype x environment (GGE) biplot analysis. The E and G × E interaction effects were found to the gr...

Alternative production practices may be able to alleviate pest problems and improve yield for smallholder growers. On-farm trials were conducted at Baliakandi, Rajbari (inland region); and Dashmina, Patuakhali and Charfession, Bhola (coastal region) in Bangladesh to evaluate yield and yield components of eggplant (Solanum melongena L.) and cucumber (Cucumis sativus L.) and income of farmers using alternative production practices. Eggplant was grown with, and without, a pheromone lure at Baliakandi, Rajbari; cucumber was grown with, and without, a pheromone lure at Dashmina, Patuakhali; and with, and without, apical clipping at Charfession, Bhola. Baliakandi, eggplant yielded 15.8 t∙ha-1 with a pheromone lure compared with 13.7 t∙ha-1 without a pheromone lure; a 15.3% yield improvement. At Charfession, the highest cucumber yield of 20.8 t∙ha-1 was obtained with apical clipping compared with 17.9 t∙ha-1 without apical clipping; a 16.2% yield improvement. The highest gross return, and gross margin, was in fields with alternative production practices at all locations. Difference of gross margin between cucumber grown with, and without, a pheromone lure was US$ 668∙ha-1 at Dashmina. Use of insect lures and/or apical clipping can improve yield.

Being a cheap source of organic matter and plant nutrients, its application may improve soil fertility, and yield quality and quantity. Field experiments were conducted at Lahirirhat Farming System Research and Development site, Rangpur, Bangladesh, to assess effects of biogas slurry in combination with synthetic fertilizer on tomato (Solanum lycopersicum L.) yield and profitability. Treatments included: soil test-based fertilizer, synthetic fertilizer+cow dung manure @ 5 t∙ha−1, synthetic fertilizer+cow dung bioslurry @ 5 t∙ha−1, synthetic fertilizer+poultry manure @ 3 t∙ha−1, synthetic fertilizer+poultry bioslurry @ 3 t∙ha−1, and farmer practice. Fruit yield was higher for plants grown with synthetic fertilizer+cow dung bioslurry compared with other fertilizer treatments and the farmer practice. Application of synthetic fertilizer+poultry bioslurry resulted in the highest fruit yield; plants maintained with the farmer practice yielded the least. The highest gross return and gross margin were obtained from plants treated with synthetic fertilizer+cow dung bioslurry. Synthetic fertilizer+poultry bioslurry-treated plants returned the highest gross return and gross margin. Application of synthetic fertilizer in combination with bioslurry has potential in increasing tomato yield and economic return of farmers.

It mainly affects those rural poor, who have an undiversified income that is directly or indirectly based on agriculture. Rangpur and Lalmonirhat districts under greater Rangpur region are severely affected by Monga. For increasing employment and food accessibility in these regions this study was undertaken. The farm accounting data for this empirical application have been collected from two districts (Rangpur and Lalmonirhat) of greater Rangpur through a farm management survey. A sample of 90 farms from each district has been surveyed taking 30 from marginal, 30 from small and 30 from medium farm groups using random sampling technique method. Farmers get lower return due to lack of crop diversification. Linear programming model used to produce optimum farm plans for marginal, small and medium farms (i) by reorganization of existing resources (ii) by combination of improved technologies with existing technologies. For increasing food accessibility and employment, optimum farm plans by reorganization of improved technology have been conducted among six farmers in the study villages at 2010-2011. By reorganization of existing cropping patterns (using Linear Programing Model) gross output (7% to 21%), gross margin (12% to 20%) and labour employment (6% to 20%) have been increased from plan1 (existing plan) to plan 2 (by reorganization of existing lands). The cause of increase gross output, gross margin and labour employment was some cultivated land from less efficient cropping patterns has been transferred to more efficient cropping patterns. Again, by reorganization of existing and improved cropping patterns, some lands of existing patterns have been shifted to improved cropping pattern. As a result, gross out (17% to 31%), gross margin (27% to 32%) and labour employment (13% to 26%) have been raised from plan1 to plan 3 (by combination of improved technologies with existing technologies). The result of on farm demonstration showed gross output, gross margin and labour employment have been increased 24% to 53%, 32% to 51% and 12% to 47% from plan1 to plan 3, respectively. So, this study suggest, optimum farm plan with the combination of existing and improved cropping pattern will increase farm output and generate additional employment.

In this regard, home gardens can play an important role in providing enhanced food supply and increased diversity of food to some extent. Studies on niche/ecosystem based homestead gardening were carried out at Lahirirhat Farming Systems Research and Development site, Rangpur under the On-Farm Research Division of Bangladesh Agricultural Research Institute during 2008–2009, resulting in the development of a year round production model, known as the Rangpur (Syedpur) model, for Tista Meander Floodplain agro-ecological region of Bangladesh. The objective of the study was to utilize the homestead resources in scientific ways for producing fresh vegetables and fruits over space and time and to enhance the nutritional supplies for the family throughout the year. A total of 12 households were selected from landless (no cultivable land), marginal (0.2–0.6 ha) and small (0.61–1.0 ha) farmer groups and seven production niches were intervened for round the year production following the Rangpur model. The niches were open sunny place, roof top, trellis, fence, boundary, marshy land and partially shady place. After the intervention, the highest amount of vegetables was produced by the small farmer groups (511 kg/year) followed by marginal (499 kg/year) and landless (422 kg/year) farmers. The yearly vegetable requirements of farmers were largely met by the homestead garden with a supply between 55 and 79 kg/head/year compared with the bench mark level of 21–30 kg/head/year before the intervention. The highest total income (BDT 5030/year) and net income (BDT 4290/year) were obtained from homestead at small farmers followed by marginal and landless farmers. From this study it is evident that the target farmers were able to fulfill their daily requirement of vegetables in most parts of the year by following the Rangpur model. This suggests an increase in food security and a reduction in malnutrition of farm families in the target households of Rangpur region in Bangladesh. The upscaling of the production model based on niche/ecosystem in different poverty stricken regions of Bangladesh is recommended to achieve food security and malnutrition reduction.

(Fabaceae, local name: orhor, English name: pigeon pea) is widely cultivated in Bangladesh for its edible seeds. The leaves are also consumed during times of food scarcity. In the folk medicinal system of Bangladesh, the leaves and stems of the plant are predominantly used for treatment of jaundice and diabetes. The objective of the present study was to evaluate the antihyperglycemic and cytotoxic potential of methanol extract of leaves and roots of the plant. Antihyperglycemic activity was studied by oral glucose tolerance tests in glucose-loaded Swiss albino mice. The methanol extract of leaves showed dose-dependent and significant reductions of serum glucose levels in mice. At doses of 200 and 400 mg leaf extract/kg body weight, the reductions in glucose levels were comparable to that of the standard antihyperglycemic drug, glibenclamide, administered at a dose of 10 mg/kg body weight. In contrast, the methanol extract of roots showed a dose-dependent i...

The experiment consisted of three maize planting dates (maize planted at the same time as okra in mid-June, maize planted 2 and 4 weeks later, respectively, in late June and early July) to okra plots. Monocropped okra and maize constituted the control plots. The five treatments were replicated four times in a randomized complete block design. The results obtained showed that the greatest intercrop yield of okra was obtained when maize was planted 4 weeks later (in early July), while the greatest intercrop yield of maize was produced when planted at the same time as okra in mid-June. Planting okra and maize at the same time in mid-June not only recorded the lowest competitive pressure, but also gave the highest land equivalent ratio (...
