Abstract/ Executive Summary:

The study was conducted to determine the yield and economic consequences of two cropping patterns viz. improved cropping pattern (Radish-Potato/Maize-T. Aman rice) and farmers’ pattern (Potato/Maize-T. Aman rice) through the incorporation of modern high yielding varieties and improved management practices for crop production. The experiment was laid out in randomized complete block design with six dispersed replications in farmers’ field condition in Domar, Nilphamari in three consecutive years 2009-12. Three years mean data showed that the improved management practices for the pattern provided a significantly higher yield in the improved pattern. The gross return (Tk. 4,32,990/ha) and net return (Tk. 1,98,324/ha) of the improved pattern were 33.56 % and 24.93 % higher, respectively compared to that of farmers’ pattern with 45.44% extra cost. The higher marginal benefit-cost ratio, land use efficiency and production efficiency indicated the superiority of the improved pattern over the farmers’ practices.

Program Area: Socio-economic and Policy

Commodity: Cropping pattern

Objectives:

The present study was designed to introduce radish in the fallow period, early potato varieties Granula instead of Diamant and alternate modern rice varieties like BINA dhan-7 instead of BR-11 for T. Aman rice.

Methodology:

The experiment was conducted at the farmers’ field condition in Rangpur at Multi-Location Testing (MLT) site, Domar, Nilphamari, belongs to Tista Meander Floodplain under the Agro-Ecological Zone (AEZ-03) of Bangladesh, in three consecutive years 2009-10, 2010-11, and 2011-12.The study was conducted to determine the economic consequences of two cropping patterns viz., ICP: Improved Cropping Pattern (Radish-Potato/Maize-T. Aman) and FECP: Farmers' Existing Cropping Pattern (Potato/Maize-T. Aman) through the inclusion of radish crop along with high yielding varieties (HYV) of rice crops early variety of potato and improved management practices for crop production. Initial soil nutrient status, temperature and rainfall in Domar, Nilphamari during cropping season (2009-12) are presented in Table 01 and Figure 01, respectively. The soil was sandy loam with medium organic matter content (2.11%) and soil pH ranged 5.65-5.69. The status of N, P, K, S, B, and Zn was Low, very high, medium-low, low, medium and medium, respectively. Bangladesh has a tropical monsoon climate with a unimodal rainfall pattern throughout the year (Ahasan, et al., 2010). The highest amount of the country's average monthly rainfall occurs in June followed by May and September and the lowest amount of rainfall occurs in January followed by of December and February. In Nilphamari, the highest amount of average monthly rainfall occurs in June followed by that of August, July, and May, whereas the lowest amount of rainfall occurs in November followed by that of December and January. Rainfall increases gradually from the month of January to June and then decreases. Annual total rainfall was 831mm, 2001mm and 852mm respectively during the period 2009- 2012. The average maximum and minimum temperatures were 30.54 and 20.93⁰C, respectively. The experimental design was a randomized complete block with six dispersed replications. Two plots of 660 m² were selected for each replication. One plot was under the improved cropping pattern and the other was the farmer’s pattern. In the improved pattern, the radish variety Rocky-40 was introduced against the fallow period. The alternate modern potato variety Granula and Aman rice variety BINA dhan-7 instead of Diamant and BR-11 for Potato and T. Aman rice, respectively, were used in the improved cropping pattern. All field operation and management practices of both farmer’s and improved pattern were closely monitored and all the necessary data were recorded for agro-economic analysis. The mean data of yield were analyzed by using MS Excel software.

Achievement/Findings:

Considering higher rice-equivalent yield, net monetary return and more sustainability of the improved cropping pattern (Radish-Potato/Maize-T. Aman Rice) with additional crop in improved technologies could be suggested for medium high land of the Teesta Meander Floodplain Agro-ecological Zone (AEZ-3) of Bangladesh. Therefore, four crops based cropping patterns viz., Radish-Potato/Maize- T. Aman Rice are suitable for the light-textured soil of Domar, Nilphamari. Radish-Potato/Maize- T. Aman Rice can be recommended for the region, especially for the marginal farmers.
