“…74.3% of the respondents (Table 1) are environmentally unconscious that leads them to adopt the fertilizer broadcasting method. It is important to note that 48% of Bangladesh's total labor force depends on agriculture [23,64], and large portions of the total population live below the poverty line; most small-scale farmers own no more than 1.0 ha of farmland [23,65]. They have limited access to efficient technologies, fertilizer spreaders or applicators, and little formal training from government extension authorities.…”

Abstract:The excessive use of inorganic fertilizers causes serious environmental degradation, resulting in lower crop yields in Bangladesh. Seventy percent of Bangladesh farmers practice traditional fertilizer broadcasting. In the 1960s, the Bangladesh state authority launched a 'Grow More Food' campaign to feed the country's increasing population. Farmers were supplied with chemical fertilizers and pesticides at a subsidized price. Farmers increased the frequency of fertilizer applications to enhance yields. These practices are still used and have caused significant environmental degradation. In this study, we examined the effects of fertilizer broadcasting on excessive use of fertilizer and environmental risks. We collected data from 211 Bangladesh infield farmers in 2016. Respondents were interviewed using a semi-structured questionnaire. Data were analyzed by applying a binary logistic regression model to test the degree of effects between the testable variables. The study found that the effect of broadcasting on the excessive use of fertilizers is strongly significant, at 1%. It also found that younger farmers have a significant effect at 10% on the excessive use of fertilizers. Bangladesh policymakers can formulate policy on sustainable fertilizer management, introducing different placement methods on the basis of this finding. After that, the Directorate of Agricultural Extension (DAE) can carry out the policy at the field level.

The study was carried out at the field of Regional Pulses Research Station, Madaripur under Bangladesh Agricultural Research Institute (BARI) during Rabi season (winter) to evaluate the effect of different tillage practices on growth, yield attributes, nutrient uptake and yield of chickpea, and to compare between the zero tillage and tillage practice.The experiment was planned with five different tillage practices viz. Zero tillage (T 1 ), Single tillage (T 2 ), Two tillage (T 3 ), Three tillage (T 4 ) and Four tillage (T 5 ), and it was laid out in a randomized complete block design (RCBD) with three replications. Blanket dose of fertilizers of N, P, K, S, Zn and B at 20, 21, 30, 10, 3 and 1.5 kg ha -1 , respectively were used in all tillage treatments. The highest mean seed yield achieved (1395 kg ha -1 ) in zero tillage (T 1 ) followed by four tillage (T 5 ) practice. The maximum number of branches plant -1 and more number of pods plant -1 was recorded in zero tillage treatment. Nutrient content showed non-significant effect across most of the treatment. The highest nodulation and nutrient (N, P, K and S) uptake was also obtained from T 1 treatment. Tillage practices exhibited positive effects on soil properties. The highest soil organic carbon, total N, available P, K, S, Ca, Mg, Zn and B were found in zero tillage (T 1 ). Based on profitability, the zero tillage was economically viable with compared to tillage practice. Although this practice (T 1 ) saves the money about 3.8% to 13.7% and time also saves minimum 8 days for succeeding crops. So, the present study suggests that zero tillage practice could be implemented in the high and medium high land for chickpea cultivation. Low income farmers may practice the zero tillage technology. Future research should be carried out to evaluate the suitable rate of nutrient in zero tillage (conservative tillage) practice for yield maximization of chickpea and sustaining soil fertility.

“…These locations are known as High Ganges River Floodplain, High Barind Tract, Old Himalayan Piedmont Plain and Old Brahmaputra Floodplain (FAO-UNDP, 1988) and classified as AEZ 11, 26, 1 and 9, respectively. The soil types were varied in the experimental plots from alluvial in Durgapur upazila, silty-clay loam in Godagari upazila, to light loamy in Gouripur upazila and Sadar upazilas of Thakurgaon and Mymensingh (Huq & Shoaib, 2013). Among these locations, the highest average annual rainfall (2522 mm) was recorded in Gouripur and Sadar upazilas of Mymensingh followed by Sadar upazila of Thakurgaon (2218 mm) and the lowest rainfall (1581 mm) was recorded in Godagari and Durgapur upazilas in Rajshahi district ( Figure 2) but in all cases about 80% of the precipitation occurs during June-September.…”

Transplanting rice (Oryza sativa L.) seedlings into non-puddled soils with minimum soil disturbance (by mechanized strip tillage) is an opportunity to expand Conservation Agriculture (CA) adoption in ricebased cropping systems. However, the farmer acceptance and on-farm profitability of this technology has not been assessed. Here, we analysed farmer-managed non-puddled transplanting (NT) of rice seedlings in paired comparisons with rice seedlings transplanted in puddled (PT) soil. Sixty-six rainfed monsoon (aman) and 84 dry-season irrigated (boro) rice crops were established by NT and compared with paired PT crops during 2013-2015 in north and north-west Bangladesh. Non-puddled fields were prepared by firstly making 40-60-mm-wide tilled strips with a Versatile Multi-crop Planter, then by 18-24-h inundation with water to soften soils in the strip, followed by transplanting seedlings into strips. The NT crops produced similar or significantly greater grain (boro season of 2015) and straw yields than paired PT crops. The minimum soil disturbance NT did not hinder seedling transplanting of rice or increase the total labour costs for transplanting and weeding compared to PT, rather it reduced the cost of production, and increased net benefit for rice in both seasons relative to PT. Under farmer management on a range of soils and in the two main rice-growing seasons, NT performed as well or better than PT suggesting that this is a feasible option for farmers planning to adopt CA in rice-based cropping systems. Over 3 years, farmers' perception of NT performance shifted from scepticism to mostly favourable.
