Description An experiment was conducted at organic farm, plot -19, F block,
N. M. College of Agriculture, Navsari Agricultural University, Navsari to study
the “Effect of different proportion of organics on productivity of pit planted
sugarcane under organic farming system” during the year 2009-10 and 2010-
11. The experiment was conducted at fixed plot site with a set of 8 treatments
of organics and 1 treatment of inorganic as control (250:125:125 kg N: P2O5:
K2O/ha) arranged outside the experimental plot for sugarcane crop. The
experiment was laid down in randomized block design with three replications.
During course of investigation observation on growth parameters,
yield and yield attributes, quality parameters, nutrient content and uptake and
also post harvest soil fertility and physical properties were evaluated.
Different organic treatments did not show any significant influence
on germination (at 30 & 45 DAP), tillering (at 90 & 150 DAP) per cent, millable
cane girth and no. of millable canes/ha during both the years and in pooled.
While, significantly higher total plant height, millable cane height, no. of millable
cane, single millable cane weight were recorded with treatment T3 (50 % RDN
through vermi compost and 50 % RDN through castor cake) during both the
years as well as in pooled analysis. Ultimately the result was reflected on yield
and significantly higher millable cane (128.00, 131.67 & 129.83 t/ha,
respectively) and trash (22.84, 23.50 & 23.17 t/ha, respectively) yields were
recorded under treatment T3 (50 % RDN through vermi compost and 50 %
RDN through castor cake), but it was found at par with treatments T4, T2 & T1
during both the years and in pooled except treatments T2 and T1 in pooled for
millable cane yield. In case of trash yield of sugarcane, treatment T3, T4 and T1
was found at par during both the years and in pooled except T1 in pooled
analysis.
In organics vs inorganic-control analysis, application of 100 per
cent RDF through inorganic fertilizers (T9) recorded significantly higher values
of growth and yield parameters and yields of sugarcane crop as compared to
organic treatments during both the years and in pooled analysis also.
The quality parameters viz., brix (%), sucrose (%) in juice,
sucrose (%) in cane, purity (%), fibre (%) and CCS (%) were not improved.
Contrary to this, CCS yield (t/ha) was significantly improved by application of
RDN through different sources of organics. However, in organics vs inorganiccontrol
analysis, all the quality parameters were significantly improved with
application of organics during both the years, except brix and fiber per cent.
In case of nutrient content in sugarcane crop, nitrogen and
potassium content was significantly affected, contrary to this, phosphorus and
micro nutrient (Fe, Mn, Zn and Cu) content of cane and trash did not differ
significantly due to different organic treatments during both the years. Among
the organic treatments, application of 50% RDN through vermi compost and
50% RDN through castor cake (T3) recorded higher N content in millable canes
(0.480 and 0.480 %) and trash (0.931 and 0.891 %). Further, significantly
higher value of K content in millable cane (0.367 and 0.365 %, respectively)
and trash (0.575 and 0.563 %, respectively) was recorded with same treatment
and recorded superior than rest of the organic treatments during both the
years.
The uptake of major and micro nutrients by millable cane, trash
and total uptake of major and micro nutrient were significantly influenced under
different organic treatments, being maximum with treatment T3 (50 % RDN
through vermi compost and 50 % RDN through castor cake) and minimum with
treatment T5. So far organics vs inorganic-control was concerned, the uptake of
N, P and K by millable cane, trash and their total were found significant during
both the years and recorded significantly higher with application of 100 per cent
RDF through inorganic fertilizers (T9) than to organic treatments mean.
The soil pH, EC (dS/m) and organic carbon after harvest of
sugarcane at surface (0-22.5) and sub-surface (22.5-50) soil depth did not
differ significantly due to organic treatments during both the years. Available
status of macro and micro nutrients (N, P, K & Fe, Mn, Zn, Cu) after harvest of
sugarcane crop was significantly improved when plot received nutrition through
50% RDN through vermi compost and 50% RDN through castor cake (T3) then
rest of organic treatments during both the years in surface soil only. The
different organic treatments did not show significant effect on bulk density,
water stable aggregate and infiltration rate of soil after harvest of crop at both
the depth of soil during both the years of experimentation.
Organics vs inorganic-control analysis, bulk density, water stable
aggregate and infiltration rate were found significantly higher with application of
organics at 0.0-22.5 cm depth of soil during both the years.
For producing higher cane and profitable yield of sugarcane, the
crop should be fertilized with 100 per cent RDF (250:125:125 NPK kg/ha) under
south Gujarat condition. Further, it is also inferred that for organic production of
sugarcane crop the application of 50% RDN through vermi compost and
remaining 50 % RDN either through castor cake or neem cake (T3 and T4) was
found most appropriate and profitable not only secure the good quality of
sugarcane produce but also improved soil physico-chemical properties of soil
and sustain soil productivity.
