Abstract/ Executive Summary:

The experiment was carried out at the research field and laboratory of Seed Technology Division BARI Gazipur during rabi season of 2013-14 to find out the suitable conservation agriculture based technology for wheat seed production and to know the varietal performance of wheat under resource conservation agriculture based technology for quality seed production. The experiment was laid out in split plot design with three replications where variety was used in main plot. The treatment comprises of two wheat variety , V₁= BARI Gom-27 and V₂= BARI Gom-28 and four conservation agriculture based technology viz. CA₀= Conventional tillage, CA₁=Strip tillage, CA₂=Power tiller operated seeder and CA₃= Raised Bed system. Plant height, spike length, No. of florate per spike, No. of grain per spike, 1000 seed weight and yield were significant with variety and different conservation tillage practices. Maximum plant height and spike length was observed from T4 ( CA₃: Raised Bed system). Higher florate no, grain per spike, thousand seed weight and finally seed yield were found from CA₃: (Raise Bed system). After harvesting significantly highest seed germination (97%) root length, shoot length, seedling dry weight and vigor index were recorded from the seeds of Raised Bed.

End Date: 00-00-2014

Program Area: Seed Technology

Commodity: Wheat

Objectives:

1.To find out the suitable conservation agriculture based technology for wheat seed production

2. To know the varietal performance of wheat under resource conservation agriculture based technology for quality seed production.

Methodology:

The experiment was conducted at the research field of Seed Technology Division, BARI, Joydebpur, Gazipur during rabi season of 2013-14. The experiment was laid out in split –plot design with three replications. Unit plot size was 10m 5m, Two variety were V₁=BARI Gom-27, V₂=BARI Gom-28 and four conservation tillage were CA₀=conventional tillage, CA₁=Strip tillage, CA₂= Power tiller operated seeder and CA₃= Raised Bed system. In case of conventional treatments 120 kg of wheat seeds were used and the conservation treatments were done by different types of power tiller operated seeder machine. Before sowing the treatments plots were fertilized with Urea, TSP, MOP, Gypsum , Boron @N₁₀₀P₃₀K₅₀S₂₀B₁. Seeds were sown on 05 December, 2013 in 20 cm row spacing in all the treatments except raised bed system. Irrigation and other intercultural operations were done as per crops requirements. The crop was harvested at harvest maturity stage. Data on yield and yield components and seed quality parameters were recorded. The recorded data were analyzed statistically and treatments were compared by LSD test.
