“…The highest variable cost was incurred by the transplanting method (59294.00 BDT ha −1 ) while the lowest variable cost was incurred by the direct seeding of dry seed method (46794.00 BDT ha −1 ). This was similar to the results of Kabir et al, [16] who found lowest variable cost in direct seeded rice due to the omission of seedling raising, uprooting and transplanting.…”

To find out the effect of planting methods on the yield and yield attributes of short duration Aman rice varieties, a field trial was conducted at the farm of Bangladesh Rice Research Institute, Gazipur, during July to November 2012. The treatments comprised of three BRRI released high yielding varieties viz., BRRI dhan39, BRRI dhan49 and BRRI dhan57 and three planting methods viz., direct seeding of dry seed, direct seeding of sprouted seed and transplanting. It was a factorial experiment conducted in a Randomized Complete Block Design with three replications. Planting methods had a significant effect on the growth duration of rice. The rice crop established with direct seeding of the dry and sprouted seed matured 7 days earlier than transplanting. The variety BRRI dhan39 gave the highest yield (4.964 t•ha −1 ) when grown with direct seeding of sprouted seed compared to other varieties. The highest net return (23362.00 BDT ha −1 ) and cost benefit ratio (1:1.49) were observed in direct seeding of the sprouted seed method. So, direct seeding of sprouted seed might be the best planting method because about 19.94% production cost is reduced due to the omission of seedling raising and transplanting operations as well as the reduction in the length of the crop cultivation period.

“…[7] reported that the increased plant spacing considerably resulted in vigorous plant growth and caused a significant increase in number of filled kernels per panicle in rice. In contrast to the results obtained [29] observed highest number of filled grains spike -1 (31.05) from the seed rate of 140 kg ha -1 and the lowest (26.55) from the seed rate of 100 kg ha 1 . This result in contrast with [33] was obtained there was no significance of difference between 20, 25and 30 cm.…”

Rice is among the most important commercial cereal crops that can be produced in North Gondar. However, its production is challenged by low yield mainly due to lack of appropriate agronomic practices and recommendations. Uses of appropriate seed rate and row spacing most importantly affect the productivity of rice. Therefore, a field experiment was conducted to investigate the effects of seed rate and row spacing on grain yield and yield components of upland rice. Factorial combinations of four seed rates (60, 80,100 and 120 kg ha-1) and three levels of row spacing (20, 25 and 30 cm) were laid out in RCBD with three replications using NERICA-4 rice variety. The combine interaction effect of seed rate and row spacing was highly significant (P<0.01) on days to heading, days to maturity, number of total tiller per meter row length, thousand seed weight and grain yield, and significant (P<0.05) on plant height. The highest thousand seed weight (27.3 g) was recorded at seeding rate (80 kg ha-1 and grow spacing of 30 cm but the lowest (17.1 g) was recorded on seed rate of 120 kg ha-1 and row spacing of 25 cm. The highest grain yield (4148.8 kg ha-1) was obtained at interaction of 80 kg ha-1 seed rate and 20cm row spacing. While the lowest grains yield (1826.4 kg ha-1) was obtained from the combination of 60 kg ha-1 seed rate and 30cm row spacing. In conclusion, the results revealed that seed rate and row spacing increased grain yield of rice by positively affecting the important yield components of the rice. The result of economic analysis showed that the maximum net benefit was obtained at seed rate of 80 kg ha-1 and row spacing of 20 cm. Hence use of 80 kg ha-1 and 20 cm is promising for upland rice variety production under the rain fed condition at Metema district and similar agro ecologies.

A field trial was conducted at Agronomy Farm of Bangladesh Rice Research Institute to find out the effect of crop establishment method and nutrient management on yield performance of BRRI developed short-duration Aman rice var. BRRI dhan62 during July to October 2016. The trial comprised of four crop establishment methods viz., M1 = BRRI recommended puddle transplanting, M2 = System of rice intensification (SRI) method (9-days old seedling transplantation), M3 = Sprouted seed in line sowing and M4 = Sprouted seed in broadcasting and three nutrient management levels viz.,N1 = BRRI recommended nutrient management, N2 = Soil test-based nutrient management, N3 = Control. The study was conducted in a factorial Randomized Complete Block Design with three replications. The result showed that planting methods had significant effects on the yield of rice. The SRI method along with BRRI recommended fertilizer dose produced the maximum grain yield of 4.49 t ha-1 which was statistically similar with that produced in SRI method day- and soil test-based nutrient management combination. The highest gross margin (Tk. 36,308.00 ha-1) and cost benefit ratio (2.06) were observed in direct seeding of sprouted seed in line sowing method along with BRRI recommended fertilizer dose. So, direct seeding of sprouted seed in line could be a suitable planting method due to reduction of 26.0% production cost associated with seedling raising and transplanting operations.
