Red Gram Cultivation

In India, red gram, also called Pigeonpea, Arhar, and Tur, is a significant pulse crop. The majority of the world's red gram crops and its consumers are located in developing nations. Here is a comprehensive introduction to red gram cultivation in India. Tamil Nadu, Madhya Pradesh, Bihar, Maharashtra, and Uttar Pradesh

Red Gram Cultivation

India is the world's top producer as well as consumer of red gram. Red gram is a basic meal, which is high in protein. The majority of the country's vegetarian population gets its protein from red gram. Red gram is mostly ingested as split pulse known as Dal, which is a crucial addition to a diet focused on cereal. The staples of the typical Indian diet are either Dal-Chawal (pulse-rice) or Dal-Roti (pulse-wheat bread). Due to the complementary nature of the necessary amino acids, when wheat or rice is coupled with red gram, the biological value increases significantly. Lysine, riboflavin, thiamine, niacin, and iron are particularly abundant.

Red gram is a significant source of both human food and animal feed, and it also contributes significantly to maintaining soil fertility by enhancing the physical characteristics of the soil and fixing atmospheric nitrogen. It is good for dryland farming and is typically grown as an intercrop with other crops since it is a drought-resistant crop.

Botany:

Red gram (Cajanus cajan L.) belonging to Leguminosae family has several species that vary in height, habit, maturation period, colour, size, and form of pods and seeds. These cultivated kinds are all divided into two groups:

i) Cajanus cajan bicolor

ii) Cajanus cajan flavus

Distribution:

Red gram is commonly grown in India, the West Indies, Hawaii, and the United States. Malawi, Australia, Kenya, Uganda, Tanzania, and Namibia. It is mostly grown in Tamil Nadu, Madhya Pradesh, Bihar, Maharashtra, and Uttar Pradesh in India.

Red Gram Varieties:

Medium duration: LRG-41, ICP-8863, ICPL-332, ICPL-87119, MRG-66, ICPL-85063, WRG-27, PRG-158, MRG-1004, WRG-53, WRG-65, TDRG-4, ICPH-2740 (hybrid)

Short duration: ICPL-84031 (Durga), ICPL-85010 and CORG-9701, PRG176

Wilt resistant varieties (hybrid): ICPL-87119, ICP-8863, WRG-65, TDRG-4, ICPH-2740

Climatic Conditions:

Red gram can only be grown in climates that are mostly tropical or subtropical. It prefers an environment that is mostly warm and damp throughout vegetative growth. However, cold, sunny days are essential for fruit ripening and pod development during flowering. It is grown in an area where the summertime high is 20 to 30 degrees and the wintertime low is 17 to 22 degrees. Temperatures can reach 40°C, although 20 to 28°C is ideal. Because of a deep root structure, the crop is severely damaged by cloudy conditions and significant rainfall during flowering. grows up to 1500 meters above mean sea level and receives evenly spaced 500 to 900 mm of rainfall.

Soil requirement for Red Gram Cultivation:

It thrives in a variety of soil types, from sandy loams to clay loams. But loamy soil that is rich and well-drained is ideal for it. Soils Pigeon pea farming benefits from alluvial and loamy soils that have adequate drainage. Because it is highly vulnerable to waterlogging during the seedling stage, it may also be cultivated on thick soils with sufficient drainage. It may grow well in soils with a pH range of 6.5 to 7.5.

Land preparation:

As a crop with deep roots, it needs a deep, finely ground, appropriately named, and well-drained seed bed. It is crucial to deep-plough using a soil-turning plough to a depth of 15 cm, followed by 2-3 discing and harrowing operations, and finally, planking. If leveling is required, it should be done to prevent water stagnation, guarantee consistent irrigation, and ensure correct drainage.

Seeds and Sowing:

Either broadcasting, line sowing, or dribbling are used to plant seeds. Sprinkle the seeds at the suggested distances. Varieties, hybrids, and cropping strategies all affect the seed rate and spacing.

Seed Rate:

Medium duration varieties: 5-10 kg/ha

Short duration varieties: 15-18 kg/ha depending on the type of soil and spacing.

Management of weeds: During its first 60 days of development, Red gram is extremely susceptible to weed competition. The crop grows quickly when protected at this time, and weeds have no further impact on its development. Spray fluchloralin at a rate of 1.5 lit per ha or pendimethalin at a rate of 2 lit per ha three days after planting, followed by irrigation. Uncontrolled weeds also reduce pigeon pea output by 21–97%.

Application of manures and fertilizers: As a base dressing, farmyard manure, compost (12.5 t/ha), or vermicompost (5.0 t/ha) are used. For rainfed and irrigated situations, applications of 12.5:25 and 25:50 kg of N: P per ha are suggested, respectively. Early-stage seedlings rely on the nitrogen in the soil and do respond to a starting dosage of 15 to 20 kg N/ha.

Crop protection:

In the nation's pigeon pea-growing regions, the gram pod borer (Helicoverpa armigera) and the pod fly (Melanagromyza obtusa) both cause serious damage and consequent production losses. It is said that the pod fly causes grain losses ranging from 2.5 to 86.8% in various regions of India. There are estimated to be 43.5 and 30.2% in preventable losses as a result of the pod borer complex, primarily the pod fly and H. armigera.

Fusarium wilt (Fusarium udum) and sterility mosaic (virus carried by eriophyid mite Aceria cajani) are the most common diseases, but SMD and Phytophthora blight (Phytophthora drechsleri / P. cajani) diseases in the North East plain (Uttar Pradesh) also significantly reduce crop yields.

Harvesting of Red Gram:

Red gram plants should be harvested when 80% of the pods are fully developed. For a few days, stack the plants. Using sticks, divide the pods, remove the husk from the grains, and dry them to an ideal moisture level (10–12%). When 75% of the pods become brown, the crop is harvested.

With a sickle, the harvest is carried out by cutting from 75 to 250 meters above the ground. Harvested plants are allowed to sun dry. Either a mechanical thresher or a person pounding the pods with a stick is used for threshing.

Yields:

Red gram yields between 20 and 25 g/ha, however with enhanced technology, 50 to 60 quintal slicks and 3-6 g/ha grains may be produced.

Storage:

The loss during storag is estimated to be up to 7.5 percent due to faulty and inefficient techniques of storage. Quantitative losses are caused by spoilage, destruction by insects, rodents, or bird infestation. Therefore, better storage options should be used to cut down on losses.
