Influence of season on the performance of an
Adsali and its Ratoon crop of Sugarcane receiving
Vermicompost and chemical fertilizers in different
combinations.
Institute of Natural Organic Agriculture, Prune and
Ugar Sugar works Limited Ugarkurd- in collaboration
with each other, Jointly Conducted Vermicompost trials
at R and D farm, of U.S.W. Ltd and also at Ainapur
on a cultivators field from 1996 onwards. So far three
crops of Adsali (CV CoC 671) and two crops of Ratoon
and one crop preseasonal cane have been harvested
and the third crop of Adsali and the second crop of
Ratoon standing in the field which when harvested
in December 1999 or January 2000 A.D.  In
view of variation in the fertility status of the soil
at the two locations and also change in the nature
of season, 1996-97 and 1997-98 (Rainfall and Minimum
temperature), the sugarcane crop behaved differently.
However, the overall trend noted is useful and beneficial
in stressing the dire need for using vermicompost
in improving the crop yield and crop quality. A consolidated
picture of efforts made by INORA and U.S.W. LTD. and
the outcome of these efforts in all six trials is
presented in this paper.
MATERIALS AND METHODS
A replicated field trial on Adsali crop of Sugarcane
(CV CoC-671) was conducted on and D farm of Ugar Sugar
works Ltd. Ugarkhurd as well as on a cultivators field
(Shri Mohanrao Mutalik) at Ainapur. The first Adsali
crop had six treatments as follows :
- Control- No fertilizer. No manure.
- Recommended dose of chemical fertilizers-namely,
N, P and k. 400 kg N, 170 kg P2O5, 170 kg K2O
per hectare.
- Vermicompost alone- 5 tonnes/ha.
- 3/4th dose of V.C. plus 1/4th of recommended
dose of chemical fertilizers.
- 1/2th dose of V.C. plus 1/2th dose of chemical
fertilizer.
- 1/4th dose of V.C. plus 3/4th dose of chemical
fertilizers. nitrogen, phosphate and potash were
added in the form of urea. Single Super phosphate
and muriate of potash respectively. for 2nd Adsali
crop, two more treatments were added. namely
- Full dose of V.C. plus recommended dose of
N.P & K fertilizers.
- Vermicompost applied at 10 MT/ha. for first
Adsali crop, there were four replications and
three for the second Adsali crop. Plot size was
one guntha (one R) for each treatment, spacing
between two rows was 3 feet.
