Title: Enhancing Basmati Paddy Yield: Essential Fertilizer Dosing
Introduction:
Basmati paddy is a cherished variety of rice known for its aromatic fragrance and long slender grains. Cultivating this high-quality rice requires meticulous care, including precise fertilizer dosing. A well-balanced approach to fertilization not only promotes healthy growth but also ensures improved yield and grain quality. In this article, we will delve into the recommended fertilizer doses for basmati paddy, considering both macro and micronutrients crucial for its optimal growth.
Essential Macronutrients:
1. Nitrogen (N):
Nitrogen is of utmost importance in rice cultivation as it stimulates vegetative growth, enhances protein synthesis, and promotes grain formation. Basmati paddy typically requires around 100-120 kg of nitrogen per hectare. It’s generally advisable to apply nitrogen in three splits: 25% as a basal dose before transplanting, 50% at the tillering stage (20-25 days after transplanting), and the remaining 25% at the panicle initiation stage (50-55 days after transplanting). The nitrogen should be evenly distributed in the field and incorporated into the soil.
2. Phosphorus (P):
Phosphorus plays a vital role in energy transfer, root development, and flowering in basmati paddy. The recommended dose of phosphorus is usually around 60-70 kg per hectare. It is advisable to apply phosphorus as a basal dose before transplanting the paddy seedlings. Incorporating it into the soil helps ensure optimum uptake by the roots.
3. Potassium (K):
Potassium is crucial for increasing the tolerance of basmati paddy to various stresses, as well as improving grain quality. The recommended dose of potassium is typically around 50-60 kg per hectare. Similar to phosphorus, potassium should also be applied as a basal dose before transplanting the seedlings.
Micronutrients:
In addition to macronutrients, basmati paddy also requires various essential micronutrients. While their doses may vary depending on soil conditions and nutrient deficiencies, the following are some key micronutrients vital for optimal basmati paddy growth:
1. Zinc (Zn):
Zinc plays a critical role in rice fertility, seed formation, and grain quality. Many soils, especially those from alkaline regions, tend to be deficient in zinc. Hence, it’s advisable to apply zinc sulfate at a dose of 25 kg per hectare along with the basal dose of macronutrients.
2. Iron (Fe):
Iron is essential for chlorophyll formation and photosynthesis. Deficiencies can lead to yellowing of leaves and decreased yield. Applying ferrous sulfate at a dose of 25 kg per hectare as a basal application helps in overcoming iron deficiency.
3. Sulphur (S):
Sulphur is involved in protein synthesis, enzyme activity, and enhances nitrogen utilization. Basmati paddy generally requires 20-25 kg of sulphur per hectare, which can be applied as elemental sulphur or gypsum before transplanting.
Conclusion:
Proper and timely fertilizer dosing is crucial for cultivating high-quality basmati paddy. While macronutrients like nitrogen, phosphorus, and potassium enhance overall growth, applying micronutrients such as zinc, iron, and sulphur ensures optimal grain quality and yield. Farmers should always consider soil testing to determine the specific nutrient requirements of their fields and seek expert guidance to ensure the best results. With appropriate fertilizer dosing, basmati paddy farmers can achieve higher yields, better grain quality, and ultimately contribute to the market’s demand for this internationally renowned rice variety.
