Abstract
The study was attempted to estimate the crop preferences under organic
farming, to asses the effect of number of years of organic farming practices and to test
the efficacy of organic farming on crop productivity. Multistage purposive random
sampling was employed for the selection of sample respondents. Wherein three zones
viz, Hilly zone, Northern Transitional zones and northern dry zones were selected
from Northern Karnataka. From each zones one district viz., Uttar Kannada, Dharwad
and Bijapur were selected based on the maximum area under organic farming. From
each district one taluk and two villages were chosen. The total sample size of 150
comprising 75 each of organic and inorganic farmers was chosen. Organic soil sample
of about 27 were collected from respective zones. Optimal scaling technique,
ANOVA technique and Regression models were employed for analysis of data. The
results of correspondence analysis revealed a stronger association between crops and
zones and organic farming practices and selected zones. While ANOVA technique
signaled a significant influence of years of farming and zonal organic practices on
various soil indicators viz., organic carbon, nitrogen, phosphorus and potassium.
Exponential growth in productivity level was observed over the period of practicing
organic farming in selected zones. The significant difference was noticed on yield
levels of performing organic and inorganic farming for different crops in selected
zones of Karnataka.
