Title: Intercropping Information for Blackgram: Boosting Yields and Sustainability


Intercropping is an age-old agricultural practice that involves growing different crops together on the same piece of land. This practice offers numerous benefits, such as increased crop diversity, improved soil fertility, effective nutrient utilization, and enhanced pest management. In this article, we will explore the intercropping potential of blackgram (Vigna mungo), also known as urad bean or black lentil.

Understanding Blackgram

Blackgram is a highly nutritious crop widely grown in various regions of Asia. It is known for its high protein content, essential amino acids, vitamins, and minerals. Traditionally, blackgram has been cultivated as a monocrop. However, intercropping can provide several advantages for both small-scale and commercial growers.

Suitable Intercropping Partners

1. Cereals: Blackgram can be effectively intercropped with cereals like maize, sorghum, or pearl millet. These cereals act as support for climbing blackgram plants, minimizing soil erosion, and ensuring better utilization of resources.

2. Legumes: Intercropping with other leguminous crops, such as pigeon pea or chickpea, can provide complementary nutrient requirements. The symbiotic relationship between these legumes and blackgram helps fix atmospheric nitrogen into the soil, enriching it for future crops.

Benefits of Blackgram Intercropping

1. Increased Yield: Intercropping blackgram with suitable companions can lead to increased overall crop yield, maximizing land productivity. This is primarily due to effective utilization of resources, such as sunlight, water, and nutrients, resulting in improved efficiency.

2. Balanced Nutrient Uptake: Intercropping enables efficient utilization of soil nutrients. The diversity of crops helps reduce nutrient imbalances and enhances nutrient uptake by different plants. As blackgram is a heavy feeder of phosphorus, intercropping with nitrogen-fixing legumes aids in phosphorus availability, promoting healthy growth.

3. Pest and Disease Management: Intercropping diversifies the crop arrangement, disrupting pest and disease cycles. Certain plant combinations have natural repellent properties, reducing the incidence of pests and diseases, and minimizing the need for synthetic inputs. For example, intercropping with marigold or coriander can deter nematodes and aphids.

4. Soil Conservation and Erosion Control: Intercropped systems better protect the soil from erosion. The presence of taller cereal plants or legumes acting as ground cover reduces the impact of heavy rainfall, wind, and water runoff. Moreover, alternating crops’ root structures contribute to better soil structure, minimizing erosion risks.

5. Income Stability: Intercropping helps diversify income sources for farmers. By intercropping blackgram with other compatible crops, farmers can ensure a consistent revenue stream throughout the year. For instance, while blackgram is harvested, the companion crop can be in its growth phase, providing continuous income.


Intercropping blackgram with suitable companion crops has several benefits, such as increased yield, improved nutrient uptake, effective pest management, soil conservation, and income stability. It offers an approach to sustainable agriculture, addressing resource efficiency, environmental concerns, and economic stability. However, it is essential to consider crops’ compatibility, nutrient requirements, and growth habits for successful intercropping. With proper planning and implementation, intercropping can be a valuable technique to maximize blackgram cultivation and contribute to the overall agricultural sustainability.
