Description Field investigations were conducted during 1987-88,
to study the influence of nutrient status of soils, ·sufficiency
of _irrigations, and irrigation water quality on 'the
yield .and juice quality of 00.62175, COT 8201 and 00.7219
in five villages under Chittoor co-operative sugar. factory
region, Chittoor and five villages under s.v.oo~operative
. sug~r factory region, Gajulamandyam.
All the soils of the above' fields were ~andy clay
loams to clay ·loams, moderately alkaline in soil reaction,
medium in available ~ and P2o5 and high in available K2o
and well above the critical limits of micronutrients viz.,
Fe, Mn, cU, and zn. ..
The available nitrogen content o; soil was
positively correlated with yield and negatively with sucrose
in all the varieties 0£ both the regions. .Soil available
P2o5 content was negatively· correlated with sucrose ·in
COT 8201 and 00.7219 of Gajulamandyam region. Soil
available R20 was positively correlated with cane. yield
and negatively with sucrose in all the varieties of Ch~ttoor
region_ only. .
The sugarcane which received more quantity of
nitrogen fertilizers and irrigations (Gajulamandyam) was
high' in dry matter production, cane 'yield, sugar yield
over the crop which received low amount of fertilizers
and less number of irrig~tions · (Chittoor region), bu~ the
juice sucrose was high in Chittoor region.
In Chittqor region COT 8201 was pe·rforming well
interms of dry matter .production, cane yeild, sugar_yield
and nutrient uptake among ·the three varieties. Where as
in Gajulamandyam region (under sufficient irrigated
conditions) co.62175 variety was performing well interms
of dry matter, cane yeild and nutrient uptake. But the
ultimate sugar yield was high in COT 8201. ·.
Of the different villages crop grown in Perumallapalli
village of both regions, was having higher dry matter,
cane yield, sugar yield, ove.r other villages. BUt · the juice
quality was good at Potambattu in Chittoor region and
Gajulamandyam village in ·Gajulamandyam region.
The cane yield was positively correlated and
juice sucrose negatively with leaf nitrogen and potassium
concentrations in all the varieties, of both the regions
at grand growth and maturity phases. The sheath .P was
positively correlated with juice sucrose and negatively
with cane yield'at maturity.
To conclude, there were variations between two
regions, and among different varieties and villages in
cane yield and juice quality. Application of more amount
of nitrogenous fertilizers anc giving more number of
irrigations will improve the cane yield and sugar yield.
The COT 8201 is ·the best variety under both the conditions
to get maximum sugar .yield. ·
