2.  It is good method for planting sugarcane.
 Yield of sugarcane is 70t/ha in India ,while
theoretical potential yield is 474t/ha.
 ICAR-IISR had developed this technique
(1984)
 Population of main shoot is increased and
tillers are reduced.
 Objective :To increase yield (double).

3.  Leave 65 cm space around the boundary of the field.
 Mark the field at 105 cm both length and width wise.
 At the cross section of these lines, dig pit of 75 cm
diameter and 30 cm depth with pit digger machine.
 Cane stalks of 2 budded setts is dipped in 0.2 per cent
solution of bavistin (2 g Bavistin in one liter of water).
 In each pit, apply mixture of 3 kg FYM + 20 g DAP + 8
g urea + 16 g MoP + 2g ZnSO4 and mix it with soil.
 Put 20 two-budded setts in a similar pattern as of
spokes in a cyclewheel.
 Spray the solution of 5 liters Chlorpyriphos 20 EC
dissolved in 1500-1600 liters of water on setts for one
ha area.

4.  Interconnect each pit with narrow channel
manually for irrigating the pits.
 Now cover the setts with 2-5 cm of soil layer.
 Apply light irrigation just after planting.
 Do first filling of pits with dug out soil at 4th leaf
stage (35-40 days after planting in spring
planting), apply light irrigation and topdress 16 g
urea per pit when soil moisture reaches at
workable condition.
 Apply urea @ 16 g per pit and, apply Furadan 3 G
@ 33 kg per ha.The gap of at least 3-4 days must
be kept in application of urea and Furadan.
 Fill the pits with dug out soil completely.
 Carry earthing –up before onset of monsoon.

5.  Tie cane in each clump in the 1st -2nd week of
August with lower dry leaves.
 In September, tie the clumps of opposite
rows together.
 Remove lower dry leaves.
 Harvest the cane close to the ground level to
take good ratoon crop.

12.  Mr I.Varatharajan, a farmer in Somenahalli village of
Dharmapuri district,Tamil Nadu, has got a yield of over 300
tonnes in a hectare.
 MrVaratharajan was awarded the best farmer award by the
Tamil Nadu Agricultural University, Coimbatore.
 Under the conventional system, the setts are grown in rows of
90 cm spacing and are arranged in a series without adequate
spacing.
 The germinated setts are very thin in appearance and ultimately
affect the number of canes in each setts and its development.
 According to Mr.Varatharajan,the pits are dug using specially
designed tractor drawn power tillers.
 The pits are then filled with top soil, 5 kg of farmyard manure
(FYM), 100 gms gypsum and 125 gms super phosphate and
watered well before planting.

13.  MrVaratharajan has spent about Rs. 1,30,000 per
hectare and has earned about Rs. 2 lakh as net income
in his first harvest.
 Under the conventional system, farmers inTamil
Nadu are at present harvesting about 130 tonnes a
hectare which yields a net income of
about Rs. 1,43,000.
 Under pit method one can expect to harvest nearly 10
ratoon crops with a yield of about 60-70 tonnes during
every ratoon harvest compared to the conventional
method where only one or two ratoon harvest is
possible," said MrVaratharajan.

14.  The growth of the crop was vigorous and they matured
at the eighth month after planting.
 Due to the equal spacing maintained on all the sides
the plants grew steadily and the nutrition supplied
through drip fertigation reduced the crop duration.
 The continuous supply of nutrition and spacing induces
the early physiological maturity that was the major
benefit the farmer.
 All the shoots are of the same age, so there is uniform
growth and sugar accumulation in the canes.
 The most important factor was that the sugarcane setts
were placed at a depth, which were always moist,
hence, in case of drought, or non-availability of water
the yield was not affected.
