Plant Crop: upto 30 days

Shedule of operations for Plant Crop upto 30 days

Time Schedule	Recommended Operations
Before planting	Plough the land up to 45 cm depth. Apply 25 tons per hectare of well decomposed Farm Yard Manure (FYM) or decomposed molasses or compost and deep plough the field with tractor. Make ridges and furrows with 80 cm spacing having 20 cm height and up to 10 m length. Apply 375 kg Super Phosphate in the furrows.
Planting day:	Select about 75,000 two-budded setts per hectare from 6-8 months old nursery or raise seedlings in poly bags with single-budded setts. Treat the setts for 10 minutes by dipping in a solution prepared with 125 gms of Bavistin, 2.5 kg urea and 2.5 kg lime in 250 litres of water. Plant the setts 2 cm deep with buds on the sides. For every 10 furrows, plant setts on 2 rows in one furrow.
3rd day after planting:	To control weeds, spray Atrataf @2.5 kg/ha in 500 litres of water with hand sprayer.
5th day after planting:	Spread sugarcane trash up to a height of 15 cm on the ridge.
25th day after planting:	Gap-fill with seedlings raised in polybags or the plants taken from the 2 rows planted- furrows in every 10th furrow.

Plant:30-120 days

Shedule of operations for Plant Crop 30-120 days

Time Schedule	Recommended Operations
30th day after planting:	Mix 5 kg Azospirillum and 5 kg phophobacterium per ha mixed with 250 kg powdered FYM. Apply at the bottom of the plants and irrigate immediately
From 35th day after planting:	From 35 to 100 days after planting Irrigate once in 7-10 days To prevent attack by early shoot borer, apply chlorpyrifos @ 250-300 g a.i./ ha on the setts and cover with soil. If 25-30% of the shoots are affected, then for every 100 metre length of furrow, mix chlorpyrifos @ 250-300 g a.i./ in water and apply using a hand sprayer on the tips and bottom of the shoots.
45th day after planting:	Do hand weeding Apply in pits a mixture of 110 kg Nitrogen, 60 kg of Potash and 35 kg of Neem cake per hectare.
60th, 90th and 120th days after planting:	Spray a mixture of Urea 2.5%, Potassium chloride 2.5% during periods of drought At 60th day, apply a mixture of 5kg azospirillum, 5kg phophobacterium and 250 kg of decomposed FYM in powder form at the bottom of the plants and irrigate immediately. At 90th day, do hand weeding; apply in pits (after earthing up) a mixture of 110kg of Nitrogen, 60 kg of Potassium and 35 kg of neem cake per hectare.
