Cotton (Gossypium L.), the king of fibres, is an industrial
commodity of worldwide importance. It has the slowest early growth
and the lowest nutrient uptake initially which increases rapidly
afterwards. Approximately the uptake of 76% of total N, 86% of P
and 82% of K take place in cotton between 49-99 days after
planting. Broadcasting of fertilizers, especially P and K, produces
fixation problems due to more soil contact. Nearly 58-71%, 30-40%
and less than 2% of total cotton growing roots are located in the
top 20, 20-40 and below 40cm soil depth, respectively. Further, it
is feasible to grow cotton with reduced tillage. The
reduced-tillage production methods results into decrease in the
number of tractor operations by 41% to 53%, fuel use by 48% to 62%
and overall production costs by 14% to 18%. A tractor operated
cotton precision planter was developed and evaluated for
differential rate application of fertilizers at different depths
along rows of seed placement under reduced tillage conditions. The
development planter shall be especially useful to professionals in
precision farming in cotton, or anyone else who is related to the
production in cotton.
