At present food-security and sustainability is a burning issue all over the world. Many indigenous food crops of Bangladesh which promises to ameliorate fruit nutritional food demand and they have the good possibility to develop the world market. Country bean is one of the most important vegetables and pulse crop which have tremendous nutritional value and this crop is cultivated round of the year. Insects, diseases, weeds and soil nutrient management were found as the major barriers for country bean production. Lack of technical knowledge and improper crop management approaches were observed to bean cultivation. To optimize the higher yield of country bean, it had to use less hazardous insecticides, fungicides, biocides, herbicides, and balanced fertilizer and bio-fertilizers in crop management practice. This review paper examined the problems and solutions for the country bean production.

Black pepper ( Piper nigrum L.) is a popular spice that is grown as tropical and subtropical plant throughout the world.
