Abstract

A study was conducted for two consecutive years to determine the yield and system productivity of two cropping patterns viz. IP: (Wheat - Jute - T. aman) improved pattern with improved management practices and FP: (Fallow - Fallow - T. aman) farmers’ pattern with farmers’ management practices in char (adjacent to the river) area of Netrakona region of Bangladesh. The experimentswere laid out in a randomized complete block design with 10 dispersed replications at a farmer’s field. The two years mean data showed that the total component crops of IP (wheat-jute-T. aman rice) gave higher yield as well as a by-product in both years. The higherrice equivalent yield (10.52 and 10.63 tha-1), production efficiency (30.13 and 30.43 kg ha-1 day-1) land-use efficiency (87.13 and 87.84%)and benefit cost ratio (2.15 and 2.11) pointed out the dominance of the improvedpattern over the farmer’s existing pattern. Higher rice equivalentyield signified that improved cropping pattern (Wheat - Jute -T. aman) could be appropriate in Netrakona region for rising crop productivity andcropping intensity.The higher production efficiency, land use efficiency and benefit cost ratio indicated the superiority of the improved pattern over the farmers’ practices.It can be concluded that farmers of the char area of the Netrakona region might follow wheat (var. BARI Gom-26) - jute (var. O-9897) - T. aman (var. BRRI dhan49) cropping system in char land for higher productivity and profitability.

Highlights

Changes in climate, population expansion, food scarcity, poverty, starvation, accelerated land cover change and environmental degradation are the foremost challenges of the 21st century (Neamatollahi et al, 2017).In the world about 1 billion people keep on hungry every day due to the inadequate food supply and thisnumber will riseup to 2 billion by 2050 (FAOSTAT, 2014)

Summary

Introduction

Population expansion, food scarcity, poverty, starvation, accelerated land cover change and environmental degradation are the foremost challenges of the 21st century (Neamatollahi et al, 2017).In the world about 1 billion people keep on hungry every day due to the inadequate food supply and thisnumber will riseup to 2 billion by 2050 (FAOSTAT, 2014). To enhance agriculture productivity improved cropping patterns and better management practices are essential. To determine the optimal use of the available resources improved cropping pattern has been developed for exploiting the net profit subjected to some limitations (Osama et al, 2017). To declare food security for increasing people in the future we need to produce huge food on a reduced amount of land (Islam et al, 2015a&b). Firstlyit may be by increasing cropping intensity by producing more crops on the similar land during whole year and secondlyby augmenting productivity of each crops (FAOSTAT, 2013; Dobermann et al, 2013; Datta et al, 2015; Ladha et al, 2016; Datta et al, 2017; Islam et al, 2017b). Different cropping pattern are available in Bangladesh and abroad and these are well reported. (Soniand Kaur, 1984; Malavia et al, 1986; Khan et al, 2005; Ferdous et al, 2011;Anowaret al., 2012;Nazrul et al, 2013; Anowar et al, 2015; Khatun et al.,2016 and Anwar et al, 2017) where a supplementary crops may be incorporated without as.ideasspread.org
