Title: Optimizing Fertilizer Dose during Paddy (Jhona) Transplanting


Agricultural productivity extensively relies on effective fertilization practices. Paddy, also known as Jhona, is one of the most important staple crops globally. To maximize crop yield and promote healthy growth, it is essential to provide appropriate nutrients during the critical period of paddy transplanting. This article aims to highlight the significance of fertilizer doses, focusing on their optimal usage during paddy transplanting.

Understanding Paddy Transplanting:

Paddy transplanting involves the manual or mechanical transfer of young paddy seedlings from nurseries to the main field. This process requires close attention to ensure the healthy development and establishment of plants. Proper nutrient management plays a vital role in enhancing transplant survival rates, overall growth, and yield potential.

Essential Nutrients Required by Paddy:

Paddy plants require three primary nutrients: nitrogen (N), phosphorus (P), and potassium (K). While nitrogen promotes leaf and stem growth, phosphorus aids in root development and overall vigor. Potassium boosts disease resistance, enhances tillering, and supports fruiting. Apart from these, paddy also benefits from secondary nutrients like calcium, magnesium, and sulfur, along with trace elements such as iron, manganese, zinc, copper, molybdenum, and boron.

Timing of Fertilizer Application:

To optimize the fertilization process during paddy transplanting, it is crucial to follow the recommended timeline. Generally, three distinct fertilizer applications are suggested:

1. Pre-transplantation: Before transplanting the seedlings, it is beneficial to incorporate organic matter into the soil to improve its fertility. Organic fertilizers provide sustainable nutrient release, enriching the soil for long-term paddy growth benefits.

2. Basal dressing application: Just before or during the transplantation process, the basal dose of fertilizers should be added to the soil. The fertilizer mixture typically contains nitrogen, phosphorus, potassium, and relevant micronutrients. With the basal dressing, the seedlings receive an initial nutrient boost necessary for early growth and establishment.

3. Top-dressing: Approximately two weeks after transplanting, a top-dressing application should be performed to supplement the nutrient requirements of the growing paddy plants. This stage is crucial for ensuring continuous nutrient supply during the prime vegetative and reproductive phases.

Determining the Fertilizer Dose:

Determining the appropriate fertilizer dose is vital to avoid under or over-fertilization, which can harm the crops and negatively impact the environment. Local agricultural universities and research institutions provide recommendations based on soil tests, crop variety, water availability, and other specific factors.

Consider both macronutrients (NPK) and micronutrients when calculating the fertilizer dose. Soil testing reveals existing nutrient levels, helping determine the precise quantities required for optimal crop growth. Additionally, factors such as seedling health, growth stage, and prevailing weather conditions should be considered to fine-tune the fertilizer dosage.


Proper fertilization at the time of paddy transplanting significantly contributes to healthy plant growth, disease resistance, and increased crop yield. Understanding the essential macronutrients and micronutrients required by paddy plants is fundamental for successful cultivation. Timely application of the basal dose and top-dressing, along with accurate fertilizer dosage based on soil testing, will help optimize paddy productivity. By adopting sound fertilization practices, farmers can ensure healthy crop growth and food security while minimizing environmental impacts.
