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.
Bangladesh is densely populated and agriculture based country. Total rice growing area was 11.38 million ha in Bangladesh which covers 74.85% of the total cultivable area and the total production of rice was 34.71 million metric tonnes (BBS, 2016). Agriculture is the single largest producing sector of economy since it comprises about 14.1% of the country's GDP and employing around 62.1% of the total labor force (BBS, 2017). There are as many as 373 small or large haors in Bangladesh (Master Plan of Haor Area, 2012). There are many haors (basin like structure) where water remains either stagnant or in flash flooding condition during the months of May to October and mainly Boro rice is grown in the Rabi season using irrigation. Geographically, most of the haors are situated in seven districts of the NorthEast Bangladesh. The districts are Sunamganj, Kishoreganj, Netrokona, Sylhet, Habiganj, Maulavibazar and B. Baria. The Hakaloki haor, Sumir haor, Dakar haor, Tanguyar haor, Gungiajuri haor, Mukhar haor, Kaowadighir haor etc are the prominent haors in Bangladesh. The total cultivated area in those haor districts is about 1.26 million hectares of which 0.68 million ha (nearly 66%) is under haor. Almost 80% of this area (i.e. 0.68 million ha) is covered by Boro rice, while only about 10% area is covered by T. Aman production (Huda, 2004). Out of these, 95 haors are in Sunamganj district of which about 70% area has now been turned into cultivated land (Master Plan of Haor Area, 2012). Boro-Fallow-Fallow and Fallow-Fallow-T. Aman are the major cropping patterns practiced in the area. So, there is a great possibility of growing modern variety rice as well as other rice and nonrice crops in the haor areas. One of the major reasons for nutrient stress is the use of imbalance fertilizers. Among the improved cultural practices, to insure proper growth, large amount of chemical fertilizers are applied in different crops field (Shakouri et al., 2012). Judicious and proper use of fertilizers can markedly increase the yield and improve the quality of rice (Alam et al., 2009). Farmers' of haor area do not apply balance doses of fertilizers because of higher yield of rice comparison to other areas of Bangladesh. It is most important that the actual fertilizer application should be known to manipulate the adequate fertilizer input supply for higher production and social appreciation to apply balance
The experiment was carried out at Sunamganj district during November 2014 to April 2015 to observe the fertilizer management and agronomic practices on the growth of boro rice (cv. BRRI dhan58) in haor area of Bangladesh. The experimental site was located under Sylhet basin (AEZ-21) having moderately acidic and medium with very low drainage facility and the soil was Loamy clays type. The experiment comprised two level of fertilizers viz. farmers' practice based fertilizer (F 1 ) and BARC recommended fertilizer dose (F 2 ) and three agronomic practices viz. farmers' agronomic practice (P 1 ), proper seedling age and proper spacing (P 2 ), proper seedling age and proper spacing + Integrated Pest Management (IPM), (P 3 ). The experiments were laid out in a 2x3 factorial fitted into a randomized complete block design (RCBD) with five farmers' replications. Fertilizer significantly affected the growth parameter of boro rice (cv. BRRI dhan58). BARC recommended fertilizer treatment gave taller plant height (90.38 cm) at harvest than farmers' practice based fertilizer treatment. The number of tillers (17.64) hill -1 at 90 DAT was significantly affected due to BARC recommended fertilizer than farmers' practice based fertilizer. The growth parameter was not significantly affected due to agronomic practices. The non-significant effect of
