In paddy sown areas, farmers should apply Rotovator once followed by
Disc plough twice.
Seed planters of various types and
disc plough, together, ensure optimal utility of seeds (thus higher yields of crops) and shelling, husking and processing equip.
For example, there was a lot of problem of rice stubbles for the sowing of wheat, farmers were burning the residues destroying soil or managing it by
disc plough or rotavator increasing cost of production.

All the tractors come with a complete set of farm implements, namely, 9 Tine Tiller, Rotovator, two furrow

The treatments were (a) manual clearing (MC): clearing with cutlass and weeds removed from the plots, (b) manual mounding (MM): manual construction of mound using traditional hoe after weeds were removed from plots, (c) ploughing (P): ploughing with tractor mounted
disc plough at about 15 cm soil depth, (d) ploughing plus harrowing (P+H): ploughed and harrowed once with tractor mounted
disc plough and harrow at about 15 cm soil depth (e) Ploughing plus harrowing plus ridging (P+H+R): ploughed and harrowed and ridged once with tractor mounted
disc plough, harrow and ridger to about 15 cm soil depth.
Further, it may be noted that the rotavator and
disc plough are used on a very limited scale in combination with cultivator.
Mercy Ndila sits on the moving tractor, her eyes switching between the
