Abstract
Agro-land suitability is a process of evaluation of agriculture land, which measures the
degree of appropriateness of agricultural land for the use of particular crop that can best
support that crop to be grown and maximise the yield. The aim of this study was to find
the suitable land for rice and wheat so that yield of crop get maximise and fulfil the
demand of growing population. The study was carried in Bhal,(some part of
Ahmedabad, Surendranagar, Bhavnagar, Kheda, Botad and Anand district of Gujarat
state, falls under “bhal and coastal area agro-climatic zone of Gujarat) where agriculture
is preferred as mainstay for the people, but production get fluctuated due to improper
selection of cultivated crop. Therefore, it is necessary to assess the suitable land for rice
and wheat to achieve maximum potential of yield. There are various criterion such as
Land Use Land Cover (LULC), slope, soil texture, soil moisture, water holding
capacity, pH, Electrical Conductivity (EC), nutrients (N, P, K) and micronutrients (B,
Fe, S, Mn, Zn, Cu) were analysed based on available data, agronomist, expert opinion
and FAO guidelines to obtain the result. An Analytical Hierarchy Process (AHP) for
Multi Criteria Evaluation (MCE) was used to obtain the suitability map using GIS
Software. Finally, a suitability map for Rice and Wheat was obtained by overlaying the
different criterion thematic map in GIS Environment to obtain the final suitability map.
The results of final suitability map for both the crops of the study showed that 13.55%
of land is highly suitable, 36.75% of land is moderately suitable, 18.9% is Least suitable
and 30.8 % is not suitable for Rice, while for wheat, 24.8% of land is highly suitable,
31.37% of land is moderately suitable, 12.4% is marginally suitable and 31.43 % is not
suitable.
