Description Not Available
Quantifying the yield potential of maize at any given site is a key to understand the existing yield
gaps and to identify the most important constraints in achieving optimal yield and profit. A well parameterized
and validated APSIM model was used to assess the productivity and yield gap of maize cv Kanchan 101
from multi-year long-term and completed experiments. A total of 30 districts with 74 soil profiles of
Madhya Pradesh were considered for the study. For the 30 selected sites, the rainfed potential yield of
maize (Ywp) ranged from 3.3 to 5.2 t ha-1 whereas the districts mean yield (Yf) ranged from 0.7 to 3.1 t ha-
1 giving yield gaps ranging from 1.7 to 3.1 t ha-1. It was observed from the long-term simulation study that
there is a good potential to improve the grain yield of maize crop by 3.0 t ha-1 provided optimum dates of
sowing and good management practices are followed in the state.
