Summary

In this video, the presenter shares valuable insights on proper irrigation techniques for rice cultivation, guiding viewers through the entire process from pre-planting to harvest. Key steps include water management before planting, during the early growth stages, and as the rice reaches its reproductive and ripening phases. Emphasizing the importance of timely water application, the video covers pest control, fertilization, and ensuring optimal rice growth. The presenter also encourages viewers to subscribe for more agricultural tips. This practical guide is perfect for beginner farmers and those seeking to improve their rice farming practices.

Takeaways

• 😀 Two days before transplanting, irrigate the field with stagnant water to stabilize seedlings and promote faster root growth.
• 😀 Use herbicides for weed control before transplanting, ensuring the rice is not disturbed by weeds or pests.
• 😀 One day before fertilization, irrigate the field lightly to ensure uniform nutrient distribution and prevent flooding.
• 😀 After the first fertilization, maintain shallow water levels to enhance fertilizer absorption without over-watering.
• 😀 Around day 15, apply herbicides to control weeds, then increase water levels to decompose the weeds effectively.
• 😀 From day 23, manage water levels carefully after the second fertilization to ensure proper absorption of nutrients by the rice plants.
• 😀 Allow the field to dry between 23 and 30 days to stimulate root and shoot growth, as rice is not suited to constant flooding.
• 😀 At around day 50, during the flowering phase, flood the field with sufficient water to support nutrient flow to the developing rice plants.
• 😀 Drain or reduce water after flowering to prevent damage from pests like sparrows, which are attracted to the ripe rice.
• 😀 In the grain-filling phase, maintain water levels to support the development and weight of the rice kernels before harvest.

Q & A

What is the purpose of the irrigation process in rice farming?

The purpose of irrigation in rice farming is to maintain a proper water level in the field, ensuring that the rice plants are nourished, promoting root and shoot growth, and preventing the plants from being disturbed by large water flows. It also helps in controlling pests and weeds.

How should the field be prepared before planting rice?

Before planting rice, the field should be irrigated with stagnant water for about two days to help in the eradication of pests like snails. This water condition also helps in stabilizing the soil and ensuring that the rice plants can grow steadily after transplantation.

When is the right time to irrigate the rice field after planting?

Irrigation should be done one day before fertilization, usually when the rice plants are around 10 days old. The water should be kept at a moderate level, not too flooded, to ensure even distribution of fertilizers and prevent excess water from disrupting the soil.

How does irrigation support the growth of rice plants after the first fertilizer application?

After the first fertilization at 10 days, the water should be kept for about 9 days to ensure the fertilizer is absorbed evenly. After this period, the water level should gradually decrease, and the soil should dry to enhance new root and shoot growth.

Why is drying the soil important for rice plants?

Drying the soil periodically, such as around day 35, is essential to accelerate the development of new shoots and roots. Rice is not an aquatic plant that thrives in constantly submerged soil; it needs dry periods to stimulate growth and prevent over-watering.

What should be done when the rice plants reach 50 days of age?

At around 50 days, rice plants enter the flowering or 'bunting' phase, which requires a significant amount of water. The field should be flooded to ensure the plants receive enough water and nutrients during this critical growth phase.

What is the purpose of water management during the rice plant’s flowering stage?

During the flowering stage, which occurs around 50 days, rice plants need continuous water to maintain proper nutrient uptake and support the development of grains. The field should be flooded so that the plants receive adequate hydration and nutrients during this stage.

When should water be drained from the rice field to avoid bird pests?

Water should be drained from the field when the rice plants are about to mature, typically after they have started to flower. This reduces the risk of bird pests, like sparrows, which are attracted to newly developed rice grains.

How does irrigation affect the rice grain filling stage?

Irrigation during the rice grain filling stage, when the grains are maturing, is essential to maintain water levels. Adequate water during this phase ensures that the grains develop properly and fill out, leading to higher quality rice production.

What is the role of water management during the final stages of rice growth?

In the final stages, around the ripening period, water should be managed carefully by keeping a sufficient level to support the filling of rice grains. This is crucial for maintaining the weight and quality of the rice before harvest.
