Book
Weeds are referred to as plants out of place. These interfere with the use of land and other resources and cause the reduction in yield and quality of produce. Weeds account for nearly 35% of total annual loss of agricultural produce. Of all the control methods, use of herbicides is becoming more popular with the increased intensity of cultivation...
Article
The crop growth simulation driven by daily climatic data can be used to predict the yield under varied climatic conditions. The simulation model can be exploited to reduce production risk and to evaluate the effect of soil, water, field management and climate on crop production. In this study, the FAO AquaCrop model was calibrated and validated for...
