Crop1&2: Measuring Crop Area And Yield Under Pure Stand, Mixed, And Continuous Cropping

Abstract

This technical report provides findings of field tests conducted in selected districts/study area in three countries i.e. Indonesia, Rwanda and Jamaica on the basis of methodology developed by the team at ICAR-IASRI on estimation of crop area, yield and production under mixed and continuous cropping. Different methods of determination of crop area and crop yield were proposed along with different estimators for estimation of crop area and crop yield. The performances of proposed methods were compared against the respective gold standards while the performances of estimators were judged on the basis of criterion of percentage coefficient of variation (CV) of estimators. The results of analysis clearly show that the double sampling regression estimator beats the linear estimator in terms of the criterion of percentage CV both for estimation of crop area and crop yield. The use of regression estimator resulted in significant savings in cost as comparatively smaller samples have the potential to give the desired level of precision.
