Sure, here’s an article on the nutrient requirements and usage in green gram, also known as the pulse crop:
Title: Nutrient Dose Usage in Green Gram (Pulse Crop)
Introduction:
Green gram, scientifically known as Vigna radiata, is a popular and nutritious pulse crop cultivated in many parts of the world. This leguminous crop is not only valued for its excellent protein content but is also rich in minerals, dietary fiber, and vitamins. Cultivating green gram with the right nutrient dosage is crucial to ensure an optimum yield, quality, and overall plant health. In this article, we will explore the nutrient requirements and proper dosage for green gram cultivation.
Primary Nutrient Requirements:
1. Nitrogen (N):
Nitrogen is an essential nutrient for proper vegetative growth and is responsible for the green color of the plant. During the vegetative phase, green gram requires a substantial amount of nitrogen, and adequate nitrogen levels result in better leaf area, increased biomass, and higher grain production. The recommended dose of nitrogen is around 20-30 kg/ha for green gram cultivation.
2. Phosphorus (P):
Phosphorus plays a crucial role in energy transfer, root development, flowering, and seed production. It promotes early plant establishment and improves overall plant health. The optimal dosage of phosphorus for green gram cultivation is around 20-30 kg/ha. Adequate phosphorus supply enhances the crop’s ability to absorb and utilize nitrogen efficiently.
3. Potassium (K):
Potassium is essential for various physiological processes in plants, including photosynthesis, enzyme activation, and osmoregulation. It helps in improving water use efficiency, enhancing disease resistance, and regulating overall plant growth. The recommended dosage of potassium for green gram ranges from 20-30 kg/ha.
Secondary Nutrient Requirements:
1. Calcium (Ca):
Calcium is necessary for cell wall integrity, root development, and nutrient uptake. It also plays a vital role in reducing the incidence of diseases in green gram. The recommended dosage of calcium for green gram cultivation varies between 1-2 kg/ha.
2. Magnesium (Mg):
Magnesium is a critical component of chlorophyll and is responsible for photosynthesis. It also acts as an activator for many enzymes and promotes energy transfer within the plant. The recommended dosage of magnesium for green gram is around 2-3 kg/ha.
3. Sulfur (S):
Sulfur is essential for the synthesis of various amino acids, proteins, and vitamins. It plays a vital role in nitrogen metabolism and overall plant growth. The recommended dosage of sulfur for green gram cultivation ranges from 10-15 kg/ha.
Micronutrient Requirements:
1. Iron (Fe):
Iron is essential for chlorophyll formation, photosynthesis, and enzymatic functions. Iron deficiency in green gram may lead to chlorosis and reduced yield. The recommended dosage of iron for green gram cultivation ranges from 5-8 kg/ha.
2. Zinc (Zn):
Zinc is necessary for enzyme activation and plays a vital role in protein synthesis and hormonal balance. It enhances plant immunity and overall crop productivity. The recommended zinc dosage for green gram is around 2-3 kg/ha.
Conclusion:
Proper nutrient dosage is crucial for achieving optimum yields and quality in green gram cultivation. As every crop and soil condition may differ, it is recommended to conduct soil tests and consult agricultural experts or local extension services to determine the specific nutrient requirements for a particular region. By providing the right nutrient dose, green gram farmers can ensure healthy plant growth, increased productivity, and nutritious pulses for consumption.
