Rice field management is a critical aspect of rice cultivation, directly impacting yield and quality. This article provides an in-depth overview of key management practices at different growth stages of rice, focusing on transplanting, tillering, panicle development, and grain filling.
After transplanting, seedlings often experience root damage, which temporarily reduces their ability to absorb water and nutrients, leading to yellowing leaves and a pause in above-ground growth until new roots develop. To ensure healthy establishment, it's essential to check for missing plants and fill gaps promptly. Water management is also crucial—after transplanting, a shallow layer of 1 inch of water should be maintained, gradually lowering it after a few days. Applying green manure when the roots are 2-3 inches long can help promote new leaf growth, and a small amount of ammonium sulfate (around 2 kg per acre) can be used for this purpose. Additionally, controlling pests like leaf miners with insecticides such as dimethoate is important to prevent damage.
During the tillering stage, rice focuses on root and shoot development, making it a critical period for determining the number of panicles. Early nitrogen top-dressing (around 2.5 kg of urea per acre) helps support vigorous growth. Maintaining shallow water levels (about 1 inch) promotes soil warming and nutrient availability, while occasional drying encourages strong root development. After the effective tillering phase, deeper irrigation can suppress excessive growth and reduce the risk of lodging. Weed and pest control is also vital during this time, targeting diseases like blast and pests such as rice thrips and leaf rollers.
As rice enters the long-spike stage, both vegetative and reproductive growth occur simultaneously. The young panicles begin to form, and the plant requires careful water and nutrient management. Applying panicle fertilizer (2.5–5 kg of urea per acre) after jointing helps increase grain numbers. Maintaining a 2–3 inch water depth ensures adequate moisture for panicle development, while monitoring for pests like sheath blight and bacterial blight is essential.
In July, high temperatures and humidity create favorable conditions for rice blast. Effective management includes proper fertilization, balanced irrigation, and regular field inspections. Chemical control using fungicides like Tricyclazole or Shibaoke is recommended, especially during heading and flowering periods. Spraying should be done early in the morning or late in the afternoon to avoid damaging flowers.
Mid- and late-season management focuses on maximizing grain filling and improving yield components. Panicle and granular fertilizers are applied based on plant needs, ensuring sufficient nitrogen without over-fertilizing. Water management shifts from continuous flooding to alternating wet and dry cycles, promoting strong root systems and preventing premature aging of leaves.
Finally, during the fruiting stage, maintaining optimal water levels and timely harvesting are crucial. Dry-wet irrigation methods help regulate water use, while harvesting should occur when grains turn golden and stems begin to yellow. Proper timing ensures maximum yield and quality, completing the rice growing cycle successfully.
