Paddy Active Tillering Stage Fertilizer Management
Paddy, also known as rice, is one of the most important staple crops in the world. It is grown in many countries and is a major source of food for billions of people. Proper fertilizer management is crucial for achieving high yields and ensuring the health of the crop. In this article, we will discuss the active tillering stage of paddy and provide guidelines for fertilizer management during this critical phase of growth.
What is Active Tillering Stage?
Active tillering stage is a term used to describe a specific phase of paddy growth when the crop is actively producing tillers. Tillers are secondary shoots that emerge from the main stem of the rice plant and eventually bear panicles (flowering heads) that produce grains. Active tillering stage is a crucial phase of paddy growth because it determines the final number of tillers that will develop and contribute to grain production.
Fertilizer Management during Active Tillering Stage
During active tillering stage, paddy requires a balanced supply of essential nutrients for optimal growth and development. Nitrogen (N), phosphorus (P), potassium (K), and micronutrients such as zinc (Zn), iron (Fe), and manganese (Mn) are particularly important at this stage.
Nitrogen Fertilization
Nitrogen is the most important nutrient for paddy growth and is often applied as urea. During active tillering stage, paddy requires a higher proportion of nitrogen than during other growth stages because the crop is actively producing tillers. The recommended rate of urea application during active tillering stage is typically between 60 and 80 kg/ha.
Phosphorus and Potassium Fertilization
Phosphorus and potassium are also essential for paddy growth and play a key role in tiller development and panicle initiation. The recommended rate of phosphorus and potassium application varies depending on soil fertility and crop variety, but a general guideline is to apply 30-40 kg/ha of P2O5 and 40-50 kg/ha of K2O during active tillering stage.
Micronutrient Fertilization
Micronutrients such as zinc, iron, and manganese are required in small quantities for paddy growth but are nonetheless important for the health and productivity of the crop. A deficiency in these micronutrients can lead to stunted growth, reduced tiller production, and lower yields. The recommended rate of micronutrient application varies depending on soil fertility and crop variety, but a general guideline is to apply 1 kg/ha of Zn, 2 kg/ha of Fe, and 2 kg/ha of Mn during active tillering stage.
Conclusion
Paddy active tillering stage fertilizer management is critical for achieving high yields and ensuring the health of the crop. A balanced supply of essential nutrients, including nitrogen, phosphorus, potassium, and micronutrients, is necessary during this phase of growth. Proper fertilizer management during active tillering stage will help ensure a healthy, productive crop and contribute to global food security.
