Crop planning and productivity assessment of the PDKV-1 watershed were
carried out in this paper using a physically based, distributed catchment modelling
system 'MIKE SHE' with the qualitative and quantitative land evaluation of
watershed. The objective of the study was to (i) calibrate and validate MIKE SHE
model for watershed; (ii) simulate hydrological water balance of watershed using
qualitative land evaluation; (iii) compute a productivity index of soils using Storie
index rating; (iv) evaluate the yield of crops based on the modified FAO model
using water balance and determine its relation with those measured by Storie
index. The crop planning was made using land capability and suitability
classification. The MIKE SHE model was calibrated to simulate the hydrological
water balance based on crop planning. The crop yields were evaluated using
MIKE SHE model and modified FAO relationship. The model showed that it
could be applied for simulating water balance with planned crop rotation. The
yields calculated by the modified FAO relationship of green gram, cotton,
sorghum and soybean were 20.9, 47.5, 38.0 and 40.2% of maximum yield of 1.1,
1.2, 5.0 and 2.5 t ha-1 , respectively. The crop yields coincided with the Storie index
with a coefficient of determination of 89.8% and indicated the utility of Storie
index for crop planning.
