Abstract
Indian soils are poor in nitrogen. Nearly 1/3 rd of Indian soils are acidic.
Food shortage in 1960s necessitated Green Revolution, ushering in the use of
high dose of chemical fertilizers and poisonous plant protection chemicals
adversely affecting the health of the soil. But long term use of these fertilizers
causes degradation of soil, compaction and reduces soil fertility. Organic manures
when incorporated into the soil it add nutrients it.
Application of FYM improves soil fertility therefore there is wide scope to
its application. FYM contains almost all the essential nutrient required for soil
The addition of farm yard manure to the field is carried out traditionally. So there
IS scope of work to distribute the farm yard manure uniformly on the soil surface.
By considering these aspects. Tractor Operated FYM Applicator was developed
and designed components were fabricated and mounted on cultivator frame.Projections of 15 plates of metal flat were given on pipe of 2500 mm length. The
distance between two projections was taken as 145 mm. Each plate had
dimensions 80 mm x 25 mm x 5 mm. Agitator was designed and fabricated in
such a way that group of three metal plates form one helix for maximum working
effectively.
The drilling attachment consisted of PVC pipes of 100 mm diameter, can
be attached to the outlets and joined to back of tyne so that proper drilling of
material in furrow. Spreading attachment consisted of five number of spouts
attached to the outlets, which spreads manure to the surface of field. The whole
assembly was fabricated and mounted on cultivator frame. The power was given
by PTO shaft. The speed of agitator decided as selected as 170 rpm.
The test results of applicator indicated that, the draft required for drilling
and spreading of FYM was 825 and 800 kg respectively. The FYM application
rate was 2236 kg/ha. The field efficiency of drilling and spreading operation was
72 and 70 % respectively. The material was drilled properly in the furrow with
application rate of 1132 kg/h and for spreading it was 1086.72 kg/h. The
operational working time for both the operation was 24 and 25 minutes
respectively. The fuel consumption observed as 1.95 and 1.92 1/h for drilling and
spreading operation respectively. The satisfactory performance was observed for
both drilling and spreading operation.
