RICE CROP GUIDE OF FIELD MANAGEMENT & FERTILIZATION
Jun 27, 2016

Growing rice and getting high yield is a task that requires profound knowledge and expertise. Here are just some of the information for reference:

- Farmers in Asia achieve, on average, about 60% only of the yield potentially achievable with existing varieties and climatic conditions.

- About 75% of the global rice production comes from irrigated rice systems, because most rice varieties express their full yield potential when water supply is adequate.

- Consistent water depth has been shown to improve the rice plants' ability to compete against weeds for nutrients and sunlight, reducing the need for herbicides.

- Harvest management preserves rice quality and yield that contribute directly to profit. Timing field draining and harvest are keys to high head rice yield.

- Modern high-yielding rice varieties absorb potassium in greater quantities than any other essential nutrient.Potassium fertilization field trials increased yields in 20 percent of the trial sites.

- Fertilizer N use efficiency in lowland rice may be maximized through a better timing of application to coincide with the stages of peak requirement of the crop, and placement of N fertilizer in the soil.

- Proper phosphorus (P) nutrition is critical for producing maximum rice grain yields. Phosphorus is very important in the early vegetative growth stages. Phosphorus promotes strong early plant growth and development of a strong root system.

- Foliar feeding has proved to be the fastest way of curing nutrient deficiencies and boosting plant performances at specific physiological stages.

- Field research has established the critical concentrations of P, K, and Zn in the soil by correlating soil test values of these mineral nutrients and rice plant performance.
