Abstract/ Executive Summary:

A farmer managed research trial was conducted in Faridpur district, Bangladesh during the 2012-13 rabi season to observe the performance of wheat varieties under two cultivation technique, bed planting and conventional tillage systems. Four wheat cultivars BARI Gom- 25, BARI Gom-26, Prodip and BARI Gom-21 were considered. BARI Gom-26 produced the highest grain yield (4.72 t ha^-1) among the varieties tested. The spike length (9.79 cm), number of grains per spike (42) and 1000-grain weight (43.24g) were higher in plants cultivated under bed planting system compared to those in conventional tillage (9.43 cm, 39 & 39.67g respectively). As such, bed planting technique gave significantly 14% higher grain yield over the conventional tillage systems (4.05 t ha^-1). A significant interaction was found when BARI Gom-26 was grown under bed planting. This combination provided the highest grain yield 4.98 t ha^-1 , while the lowest yield was obtained from Shatabdi cultivated under conventional tillage systems (3.62 t ha^-1). Comparing cost and benefit, bed planting reduced cultivation costs (ploughing, seeding, weeding, irrigation, rat control) by around 30% compared to conventional tillage.

Start Date: 20-11-2012

End Date: 15-03-2013

Program Area: Crop-Soil-Water Management

Commodity: Wheat

Objectives:

To determine the performance of wheat genotypes under bed planting compared to conventional tillage wheat for the Faridpur region.

Methodology:

The trial was conducted in greater Faridpur region, Bangladesh under CSISA-CIMMYT Faridpur hub during the 2012-13 rabi season to observe the performance of wheat varieties under two cultivation techniques: bed planting and conventional tillage. Four wheat varieties including BAR! Gom-25, BARI Gom-26, Prodip and Shatabdi were compared under each crop establishment system. Nine farmers from three districts across Faridpur, Rajbari and Gopalganj participated in the study. The trial was laid out in a sub sub plot design. Bed planter temporally provided by CIMMYT was used by the local service providers (LSPs). The LSPs used the bed planters by replacing their existing tillers in their own two wheel tractors (2WT) for ploughing, seeding and preparing beds simultaneously. Unit plot size was 400 m². The seeds were sown during 20-27 November 2012 in both bed planting and conventional tillage systems irrespective of location. In conventional system farmers used around 150 kg ha! wheat seeds, while in bed planting the seed rate was 120 kg ha^-1 Fertilizers were applied as 115-32-45-22.5-1.25 kg ha+ N-P-K-S-B following recommended application methods. The crop was irrigated 2-3 times. The first one was provided 16-24 days after sowing (DAS), the second one during 45-55 DAS and the third and last one at 70-83 DAS based on moisture status of soil. Weeding was done once in all the replications during 20-32 days after sowing (DAS). No remarkable pest infestation was observed. The crop was harvested during 15-22 March 2013. The data on plant population were recorded considering two square meter area from three places randomly selected from each treatment plot and then averaged as one m². Plant height and spike lengths were measured, grains per spike was counted manually. The 1000- grain was weighed with an electronic balance and the grain yield recorded plot wise. The collected data were analyzed using CropStat statistical tool. The cost and return comparing bed planting with conventional tillage was also analyzed.

Achievement/Findings:

BARI Gom-26 produced the highest grain yield (4.72 t ha^-1) among the varieties tested. The spike length (9.79 cm), number of grains per spike (42) and 1000-grain weight (43.24g) were higher in plants cultivated under bed planting system compared to those in conventional tillage (9.43cm, 39 & 39.67g respectively). As such, bed planting technique gave significantly 14% higher grain yield over the conventional tillage systems (4.05 t ha^-1). A significant interaction was found when BARI Gom-26 was grown under bed planting. This combination provided the highest grain yield 4.98 t ha^-1 , while the lowest yield was obtained from Shatabdi cultivated under conventional tillage systems (3.62 t ha^-1). Comparing cost and benefit, bed planting reduced cultivation costs (ploughing, seeding, weeding, irrigation, rat control) by around 30% compared to conventional tillage.
