There is a difference of 45% to 55% between the attainable yield and potential rice. This gap may be due insufficient inputs poor mechanization status. In this regard, agricultural utmost importance obtain satisfactory yield. study was conducted determine level, power per unit area, probit regression, challenges faced by farmers understand status in rice cultivation. For this, 98 households Pyu...

Cereal production around the world is critical to the food supply for the human population. Crop productivity is primarily determined by a combination of temperature and precipitation because temperatures have to be in the range for plant growth and precipitation has to supply crop water requirements for a given environment. The question is often asked about the changes in productivity and what...

Justifiable usage of large-scale crop model simulations requires transparent, comprehensive and spatially extensive evaluations of their performance and associated accuracy. Simulated crop yields of a Pan-European implementation of the Environmental Policy Integrated Climate (EPIC) crop model were satisfactorily evaluated with reported regional yield data from EUROSTAT for four major crops, inc...
