ALGERIE, MOTOCULTEUR POUR SEMER DES FOURRAGES EN STRIP-TILL

 Pour de petites surfaces fourragères, le motoculteur est intéressant pour semer. Le strip-till (travailler le sol que sur le rang permet des économies).  Voir les  3 vidéos.

Remarquez le semoir et la trémie pour localiser l'engrais sur le rang.

Introduction
Conservation agriculture (CA) based two wheel tractor (2WT) operated seeding implements are becoming popular among farmers. About 700,000 2WT are operating in Bangladesh. In Bangladesh, no-till seeder of 2WT was first developed in WRC, BARI with FAO-CIMMYT supported programme (2003-04). This seeder had no press wheel and limitation to bold size seeds sowing. The no-till seeder was improved with ACIAR support with the introduction of lighter weight toolbar frame, press wheel attachment, seed and fertilizer box fixing over the handle bar of a tractor for free flow of seeds to ground (Hossain et al., 2009). This seeder performed better through crop residue but operators were still not satisfied due to the height of seed box which blocked the forward view of the field being seeded. Therefore, a user-friendly, small 2WT no till seeder was developed capable of handling most seeds and managing residue properly.
Materials and methods
Two wheel tractor operated no-till seeder is a pull type seeder and it has been developed in BARI Rajshahi. The major components and specifications are shown in Table 1. All accessories were set up under the handle bar of the tractor. Field performance and adaptive trials were conducted in the farmers’ fields by attaching a 12Hp Chinese Dongfeng 2WT in North West drought prone area during 2011-14 for wheat, mungbean, chickpea, maize and rice establishment (Fig.1).

Field performances of the seeder were recorded as per Regional Network of Agricultural Machinery (RNAM) Test Code. Cost was calculated according to the farm machinery utilization method (Hunt, 1995).
Results and Discussion
Field performance of the no-till seeder for wheat, maize, mungbean, chickpea establishment in several farmers’ field indicated that crops can be established immediately after rice harvest using residual soil moisture. There was enough ground clearance (45 cm) between soil surface and toolbar frame. Furrow opener layout facilitated crop residue passage without blockage. Row positions can be adjusted sliding the clamp of tynes on the toolbar frame. Effective field capacity of the seeder was 0.12 ha/hr. Seeding with 4 tynes was more appropriate for soft to medium hard soil and 3 tynes for hard soils. The inclined plate seed metering device performed satisfactorily with small to large seeds (Table 2). The seeder was tested in a wheat-mungbean-rice crop rotation lasting 4 years at Rajshahi where the soil type is dominantly silty clay loam. Rice was seeded directly in unploughed/unpuddled soil. There were no significant yield variations between no-till and conventional method (Table 3). Weed management in no-till rice cultivation is still challenging to convince traditional rice farmers.

Comparison of yield (t/ha) between no till and conventional planting method Planting cost and break-even point used for no-till seeder was calculated on the basis of fixed cost and variable cost. There were significant cost differences between no-till and conventional practice (Table 4). Break-even point of no till seeder was 4.0 ha.

The 2WT (9Kw) no-till seeder can pull 4 tynes in soft to medium hard soil but 3 tynes in hard soil and it was capable of seeding through heavy rice and wheat residue (1.5 - 2.4 t/ha) without blockages as there are sufficient clearance between toolbar frame and ground surface. The seeder is low cost (US$ 350-400; without power unit), light in weight and local manufacturer can fabricate complete set of no-till seeder within a short period of time. The no-till seeder can be used in other Asian countries where the 2WT is the common farming equipment.
