Green gram, also known as moong, is an important pulse crop grown widely across India. It is popular among farmers because it has a short duration, improves soil fertility, and gives good returns with low input cost. To get good yield and healthy crop growth, maintaining the correct seed rate and spacing is very important. Proper plant population helps the crop use nutrients, water, and sunlight efficiently and reduces pest and disease problems.
The seed rate of green gram depends on the variety, sowing method, and season. Generally, for line sowing, a seed rate of about 8 to 10 kilograms per acre is recommended. When green gram is sown by broadcasting, the seed rate may be slightly higher, around 10 to 12 kilograms per acre, to ensure adequate plant population. Using the correct seed rate avoids overcrowding and helps in uniform crop growth.
For summer green gram grown under irrigated conditions, a slightly lower seed rate is sufficient because germination is usually better. In kharif season, when rainfall is uneven, farmers may use a slightly higher seed rate to compensate for possible seed loss due to heavy rain or poor germination.
Spacing plays a key role in the growth and yield of green gram. Proper spacing allows plants to grow freely, develop good branches, and form more pods. It also improves air circulation within the crop, reducing the chances of disease. For most green gram varieties, a row spacing of 30 centimeters and plant-to-plant spacing of 10 centimeters is recommended. This spacing is suitable for both irrigated and rainfed conditions.
In case of spreading or bushy varieties, slightly wider spacing may be followed to allow better branching. For late-sown crops or varieties with less branching, closer spacing helps maintain proper plant population.
Line sowing is always preferred over broadcasting because it helps maintain uniform spacing and makes intercultural operations like weeding easier. Using seed drills or line markers helps achieve proper spacing and depth. Green gram seeds should be sown at a shallow depth of about 3 to 5 centimeters to ensure quick and uniform germination.
Before sowing, seed quality should be checked. Healthy and certified seeds give better germination and uniform plant stand. Seed treatment helps protect young seedlings from soil-borne diseases and pests. Inoculating seeds with suitable biofertilizer helps improve nitrogen fixation and plant growth.
Maintaining proper spacing also helps in better weed management. When plants are evenly spaced, they cover the soil surface faster and suppress weed growth. This reduces the need for frequent weeding and saves labour.
Proper seed rate and spacing also support efficient nutrient use. Overcrowded plants compete for nutrients and water, leading to weak growth and fewer pods. On the other hand, too wide spacing reduces plant population and lowers yield. Balanced spacing ensures each plant gets enough resources to grow well.
In conclusion, the recommended seed rate for green gram is about 8 to 10 kilograms per acre for line sowing and slightly higher for broadcasting. A spacing of 30 centimeters between rows and 10 centimeters between plants is ideal for most varieties. Following the correct seed rate and spacing, along with good crop management practices, helps farmers achieve healthy growth, better pod formation, and higher yield in green gram cultivation.
