AFACI 회원국 4개국의 수도작 포장의 멸구류 발생 양상을 조사하기 위해서 황색 점착트랩을 이용하여 타락법으로 멸구류 발생 모니터링을 수행하였다. 전반적으로 모든 조사 지점에서 벼멸구의 발생량이 많았으며 상대적으로 흰등멸구의 발생량은 적은 편이었다. 애멸구의 발생은 없었다. 분얼기부터 호숙기까지 벼 멸구류의 발생량은 지속적으로 증가하였으며, 한국의 경우와 다르게 1~2회의 발생 최성기(Peak)가 나타나지 않았다 벼멸구의 경우 모든 조사 지점에서 발생하였으며 스리랑카의 Svay Reang에서 조사기간 동안 평균 1,673마리로 가장 많이 발생하였으며 방글라데시의 Dobila, Hamkuria, 남베트남의 Cho Gao가 각각 1,236마리, 818마리, 666마리 순이었다. 흰등멸구의 경우 조사지점 간 편차가 크게 나타났는데 방글라데시의 Dobila에서는 조사기간 동안 평균 1,163마리가 발생하였으나 남베트남에서는 거의 발생하지 않았다.

The purpose of this study is to identify the effectiveness of satellite images in detecting the areas of rice production in the Barisal of Bangladesh. We also investigated the effect of climate change on the crop production through comparative analysis of rice production area and production statistics with climate data at multi-temporal time scale. This analysis found that the classification of rice fields extracted through satellite image and made as the number of rice cultivation areas did not exceed 10 percent of the statistical data. Climate data analysis showed that the average temperature during the ripening stage has the greatest impact on Boro’s production. It would be more make sense if you can describe the results of how precipitation is also important for rice production in addition to temperature. Therefore, it is believed that this research could serve as a key basis for solving food security issues due to climate change.

A field study was conducted to develop an economically suitable combination of organic and inorganic fertilizers for sugarcane cultivation in sandy acidic soil of a commercial sugarcane farm under Old Himalayan Piedmont Plain of Bangladesh. Results revealed that the treatment T4 which received 75~% of Recommended fertilizers (N 120, P 35, K 100, S 25, Zn 2 kg ha-1 ) + 10 Mg ha-1 Rice mill ash + Mg ha-1 press mud significantly produced higher sugarcane yield (72.34 Mg ha-1 ) among all the treatments except T5 having 100~% of Recommended fertilizers + 10 Mg ha-1 Rice mill ash + 10 Mg ha-1 press mud, which was identical. T4 also gave the highest net economic benefit at Bangladesh Taka 15,920.47 per hectare from the added nutrient management. Thus, the integrated use with organic and inorganic fertilizer is highly essential for sustainable production of sugarcane in commercial farm of the region in Bangladesh, where it has been grown year after year.
