Chickpea production in Bangladesh has been decreasing over time. Comprehensive farmlevel adoption of modern chickpea varieties can change the scenario. This paper endeavours to ascertain the determinants of adoption and adoption intensity of improved chickpea variety in the high barind region of Bangladesh. The outcomes from Cragg’s double hurdle model showed that organization membership, information sources, crop diversification index, and village location are the crucial factors that positively influenced both the adoption and adoption level. Farmers with organization membership are 15.5% more probable to adopt improved chickpea while by adding one more information source, the adoption probability can be increased by 6.3%. Meanwhile, women’s decisions, training, credit accessibility, and farm size have effects only in favour of initial adoption. The adoption probability is approximately 15% more in the household where women can participate in the decision-making process. Adopters with higher formal education, off-farm income, and mobile usage capability devote a greater proportion of their land to the improved variety cultivation. Strengthen of the network among farmers and their information sources should be emphasized to stimulate the diffusion process of the improved chickpea variety. Besides, training should be available for both female and male of the farm families since women also affect the adoption decision. Int. J. Agril. Res. Innov. Tech. 10(1): 56-63, June 2020
The cultivation of improved chickpea varieties has been increasing over time that kicks off the local varieties from the farmer’s field. Up-to-date socio-economic information regarding this issue is scanty in Bangladesh. That is why we analyze the profitability of improved chickpea variety and assess the impact of its cultivation on the livelihood of chickpea farmers in the high Barind region of Bangladesh. The values of benefit-cost ratio depict that the improved variety is more profitable in comparison to local chickpea variety; specifically, the benefit-cost ratio (BCR) of improved chickpea production is 1.87, while it is only 1.66 for local chickpea. To understand the wellbeing of chickpea farmers, the multidimensional livelihood index (MLI) following sustainable livelihood framework of the Department for International Development (DFID) is used, which constitutes the asset pentagon of five capitals namely human, physical, natural, financial and social capital. The MLI of improved and local chickpea growers are 0.51 and 0.39 respectively which belong in the middle livelihood category. Meanwhile, the MLI reflects that the improved variety cultivars are in a better livelihood condition than the local variety growers. Among all the five capitals of the MLI, the difference between these two groups is the largest in the case of social capital followed by financial capital. Since both groups have achieved far less MLI values than 1, the recommendation is therefore to ensure different types of facilities for the development of people of high Barind tract as well as increasing the production of improved chickpea.

Nitrogen is one of the most deficient plant nutrients in Bangladesh soils. The use nitrogenous fertilizer especially urea is a commonly used fertilizer for rice production but its efficiency very low about 30-40% under traditional broadcast method A field experiment was carried out in the Soil Science Field Laboratory of Bangladesh Agricultural University, Mymensingh during Aus rice growing season of 2014 to investigate the effects of prilled urea, urea briquettes and NPK briquettes on the growth, yield, and nitrogen use efficiency of BRRI dhan48. There were six treatments as T1 [check (N0P16K42], T2 [Urea briquette (one-3.4 g) (N52P16K42)], T3 (Urea briquette (one-2.7 g (N78P16K42)], T4 [NPK briquette (one-3.4g)(N51P13K32], T5 [Prilled urea (N78P16K42)] and T6 [NPK briquettes(two-2.4 g briquettes (N78P15K42)]. The experiment was laid out in a Randomized Complete Block Design (RCBD) with six treatments and four replications. Prilled urea was applied in two equal splits application; at 8 days after transplanting (DAT) and the second dose after 38 DAT, while for urea briquettes and NPK briquettes were deep placed (8-10 cm depth) at 8 DAT between four hills at alternate rows. Water samples were collected for every 7 consecutive days and analyzed for NH4-N. The results showed that the NH4-N concentration in floodwater reached to maximum on day 2 in PU treated plots and then decreased with time, while the urea briquettes and NPK briquettes treated plots slowly produced NH4-N over the growth period. The highest grain yield of 4.75 t ha-1 (69% over control) was obtained in the treatment T3 [Urea briquette (one-2.7g) (N78P16K42)]. The treatment T3 also produced the highest straw yield of 5.49 t ha-1. The maximum apparent N recovery and the maximum N use efficiency were found in the treatment T4 [NPK briquette (one-3.4g) (N51P13K32)]. It appeared that the deep placement of urea briquettes and NPK briquettes reduced N-losses and enhanced the recovery of applied N as well as N use efficiency in comparison with PU application.
The study is conveyed to compare the profitability of chickpea and boro rice in Rajshahi district, which is one of the most drought-prone areas of Bangladesh. In this study, a total of 180 farmers (90 chickpea growers and 90 boro rice growers) are used as sample respondents, and data were collected by using a structured questionnaire in 2019. A probit regression model is used to find out the determinants that affect the cultivation of chickpea and boro rice. The important finding of this study is that the Benefit-Cost Ratio for chickpea and boro rice production is 1.88 and 1.05, respectively. The results indicate that chickpea cultivation is more profitable than boro rice cultivation. Besides, the study reveals that occupation, farm size, and seed have a positive impact while family size, human labor, and irrigation have negative effects on farmer’s decision to cultivate chickpea cultivation rather than boro rice. It is, therefore, concluded that the farmers should be encouraged to grow more chickpea rather than boro rice as a means of increasing farm income through crop diversification program. Int. J. Agril.
