An on-farm crop sequence (monsoon rice-wheat-mungbean) experiment was conducted at the farmers' field located at Durbachara village of Bhangnamari union, situated at Gouripur sub-district under Mymensingh district of Bangladesh, geographically at 24"75'N and 90"50'E, at 18 m altitude. The experiment site is situated on the Old Brahmaputra Floodplain of predominantly dark grey non-calcareous alluvium soils under the Sonatala series (BARC, 2018). The experimental field was flood-free medium-high land, and the soil texture was sandy clay loam (50% sand, 23% silt, 27% clay), having pH 7.2. During the study period, March was the warmest month when the highest maximum temperatures were 30.6 and 31.060 C, and the highest minimum temperatures were 18.4 and 20.20 C in the first and second year, respectively, followed by February. Temperature declined gradually from November to January. January was the coldest month. November in 2014 and December and March in both years were the driest months when no rainfall was recorded. The highest rainfall event comprising about 20 mm was recorded in February during both years. November and March enjoyed the highest sunshine hours, while December had the least sunshine hours during both years. The experiment included four seed rates viz. 100, 110, 120, and 130 kg ha-1 of BARI Gom-26 and two tillage methods viz. conventional tillage (CT) and minimum tillage in the form of strip-tillage (ST). The experiment was laid out in a randomized complete block design with four replications. CT was done using a two-wheel tractor (2WT). The land was prepared by four plowing and cross ploughings followed by sun-drying for two days and levels. The SP was done by a Versatile Multi-crop Planter (VMP) in a single pass operation. Strips were prepared for four rows, each 6 cm wide and 5 cm deep. Three days before ST, glyphosate herbicide was applied @ 3.7 L ha-1 (Haque et al., 2017). In CT, seeds were broadcasted manually. In ST, continuous line sowing at 20 cm apart was done using the VMP according to the seed rates. Seeds were covered with soil just after sowing. The nitrogen in the form of urea, phosphorus from triple superphosphate, potassium from muriate of potash, and sulfur from gypsum was applied @ 100, 26, 33, and 20 kg ha-1, respectively. The entire amount of PKS was broadcast before seeding. Two-thirds of the N was applied at the final plowing and one-third at the crown root initiation (CRI) stage. Weeding was done by hands at 15, 30, and 45 DAS. Irrigations were applied at 20, 55, and 80 DAS. First and third, irrigation was very light and excess water was drained out to prevent wilt and lodging. Cutworm was controlled by Tricosale 20EC @ 500 ml ha-1. Bipolaris leaf blight was controlled by Tilt 250EC @ 0.5 ml L-1 of water. The bird was kept away for 10 DAS, and rodents were controlled using zinc phosphide poison. The crop was harvested at maturity (when 80% of spikelets turned brown) on March 25, from three randomly selected patches of 3 m × 1 m in each plot. Plant population and number of tillers and spikes m-2, spike length, and the number of spikelets and grains spikes-1 were recorded from ten randomly selected hills before harvest. The weight of 1000-grains and grain yield was recorded. Grain yield was adjusted at 14% moisture content, and percent yield increase over control (YOC) was calculated as described below. YOC(%) = yield in treatment − yield in control/yield in control x100. The economics of crop production was estimated following the partial budgeting system. The variable costs were calculated based on labor requirements for sowing/transplanting, weeding, harvesting and threshing, irrigation, fertilization, and all other input costs like seed, fertilizer, irrigation, etc. The gross return was calculated based on the yield and market price of grain and byproducts. The gross benefit was calculated by deducting the variable cost from the gross return. The benefit-cost ratio (BCR) was calculated by using the formula as follows. BCR = Gross return/The total cost of production. Data were subjected to two-way analysis of variance where Duncans' Multiple Range Test compared means at P ≤ 0.05. The statistical package program STAR (IRRI, 2014) was used to analyze all data.
