Desiccation of Pulses

Legumes (pulses) are more susceptible to weather damage than cereals, so a delay in harvesting can lead to loss of yield and deterioration of quality. To reduce the time from maturity to combining, field crops may be desiccated. Desiccation is the chemical termination of plant growth at the stage when all growth functions, seed size […]

The Panama disease that threatened to wipe out bananas in the 1950s had made an aggressive comeback. This current outbreak […]

Benefits of tissue testing

How to tap into the several benefits of tissue testing Managing fertility in crop production is not the easiest thing to do. Nobody holds all the pieces of the puzzle.
