The time of application of various splits are as under
\nFour splits Three splits Two splits
\n1 At planting 1 At planting 1 At planting
\n2 At 8 weeks 2 At 12 weeks 2 At earthing
\n3 At 14 weeks 3 At earthing
\n4 At earthing
\nPhosphate and potash may be applied at planting alone or in two splits doses in the prop oration of 3:1 or 1:1 at the time of planting and earthing up respectively.

Further the study revealed that split doses of Nitrogen i.e. 25 kg at planting, 75 kg after 8 weeks, 25 kg after 14 weeks and 50 kg at earthing and phosphorus and potassium in two equal split doses i.e. 50 kg at planting and 50 kg at earthing up should be applied.<\/span> <\/span><\/div>\n <\/div>\n<\/td>\n<\/tr>\n \n| \n Studies conducted at Akola during 1986-87 to 1988-89 confirmed the earlier recommendation of 175 kg N \/ha for suru planting ( Co 740, Co 62175) The same dose also holds good in case of Co 7219 (Sanjivani) and CoM 7125 (Sampada) for Eco-unit VI.

The cost of weed control by cultural methods ( 3 hand weeding) was the lowest. However, when labour is in short supply use of Atrazine 2.5 kg \/ha. or Diuron 1 kg \/ha on soil prior to weed emergence has been recommended.<\/span><\/div>\n <\/div>\n<\/td>\n<\/tr>\n \n\nStudies conducted during 1979-80 to 1981-82 to determine the scheduling of irrigation to sugarcane reveled that when irrigation is scheduled at cumulative evaporation of 125 mm (16 irrigations) instead of 75 mm (25 irrigation) the harvestable cane tonnage decreased from 96 mt to 80 mt \/ha. Hence, 25 irrigations at 75 mm CPE have been recommended. The study further revealed that when irrigation water is limited trash mulching @ 2.5 t\/ha after the emergence of sugarcane with 16 irrigations scheduled at 125 mm CPE is recommended.<\/span> <\/span><\/div>\n<\/td>\n| \n | | | | | | | | | | | |
