Moringa, scientifically known as Moringa oleifera (Drum Sticks), is a versatile and highly beneficial plant that has been revered for its nutritional and medicinal properties for centuries. Native to parts of South Asia and Africa, Moringa is now cultivated in various regions worldwide due to its incredible adaptability and numerous health benefits. Moringa is often referred to as a "superfood" due to its exceptional nutritional value. The various parts of the Moringa tree, such as leaves, seeds, flowers, and pods, are rich sources of essential vitamins, minerals, and antioxidants.

Here is a breakdown of the nutritional components found in 100 grams of Moringa leaves:

1. Vitamins:

Vitamin A (Beta-Carotene): Appro. 6780 μg (microgram)

Vitamin C (Ascorbic Acid): About 220 mg

Vitamin E (Alpha-Tocopherol): Around 47 mg

Vitamin K: Roughly 301 μg

Vitamin B1 (Thiamine): Approximately 0.257 mg

Vitamin B2 (Riboflavin): About 0.66 mg

    Vitamin B3 (Niacin): Around 2.22 mg

    Vitamin B6 (Pyridoxine): Roughly 1.2 mg

    Folate (Vitamin B9): Approximately 40 μg

2. Minerals:

    Calcium: Approximately 185 mg

    Magnesium: Around 147 mg

    Phosphorus: Roughly 112 mg

    Potassium: Approximately 337 mg

    Iron: Around 4 mg

Drone technology, also known as Unmanned Aerial Vehicles (UAVs), has been increasingly adopted in agriculture to enhance farming practices and improve overall efficiency. Drones offer various benefits, including cost-effectiveness, data collection capabilities, and the ability to cover large areas quickly. Here are some of the common applications of drone technology in agriculture:

1. Crop Monitoring: Drones equipped with high-resolution cameras and multispectral or hyperspectral sensors can capture images and data of crops from the air. This data helps farmers monitor plant health, identify areas of stress or disease, and assess the effectiveness of irrigation and fertilization practices.

2. Precision Agriculture: By combining drone-collected data with Geographic Information System (GIS) technology, farmers can create detailed field maps. These maps provide insights into variations in soil properties, allowing for targeted application of resources like water, fertilizers, and pesticides. This practice helps optimize inputs and reduce environmental impact.

3. Crop Spraying: Drones can be equipped with spraying systems to apply pesticides, herbicides, or fertilizers precisely to crops. This targeted approach reduces chemical usage and minimizes human exposure to potentially harmful substances (this can be observed in the image above).

4. Crop Assessment and Yield Estimation: Drones equipped with advanced sensors can assess crop health, estimate yield potential, and predict harvest times. This information is invaluable for better planning and decision-making in the agricultural process.

5. Livestock Monitoring: Drones can also be used to monitor livestock, enabling farmers to locate and assess the condition of their animals in large or remote areas. This aids in detecting any health issues or distress.

6. Soil Analysis: Drones can collect soil samples from different parts of a field, providing farmers with crucial soil health data. This information helps in understanding soil fertility and tailoring crop management strategies accordingly.

Liquid Fertilizers: Enhancing Crop Productivity and Sustainability (By: Prachi S. Mahajan)

 Liquid Fertilizers: Enhancing Crop Productivity and Sustainability

Author: Prachi S. Mahajan (M.Sc.  Agriculture)

Introduction: Agriculture-allied sectors serve as the backbone of countries' economies, providing livelihood to millions of people and meeting the food demands of a large population. To achieve higher crop yields with sustainable agricultural practices, nowadays farmers are turning to liquid fertilizers (LF). Liquid fertilizers play a significant role in modern agriculture by improving crop yield and quality. These LF are having the ability to provide nutrients directly to the plant roots or aerial parts which ensures efficient nutrient uptake, reducing nutrient losses due to leaching or volatilization. Additionally, applications of liquid fertilizers make possible the use of various agricultural practices, such as no-till farming, reduced-tillage systems, and precision farming. This review is about the exploration of various types of liquid fertilizers commonly used in agriculture, and gardening, with their role in improving biomass, productivity, and health.

·         Types of liquid fertilizers

1. Nitrogen-Based Liquid Fertilizers: These fertilizers provide essential nitrogen, promoting leafy growth and overall plant vigor. Recently developed “Nano-urea” is a cutting-edge innovation. These nanoparticles deliver nitrogen to plants more efficiently by minimizing nitrogen losses and environmental impacts (one can visit for more information https://www.iffco.in/en/nano-urea-liquid-fertilizer).
