Cluster beans or guar bean naturally called as Cyamopsis tetragonolobus is a yearly vegetable. It is otherwise called gawaar in Hindi and Marathi, Goruchikkudu kaya or Gokarakaya in Telugu, Gorikayie in Kannada and Kotthavarai in Tamil. Cluster Beans are a sort of green beans. They are a compliment, littler cousin of the customary green (French or string) beans. Erect yearly herb 1-2 m high, hairs parallel to the surface; leaves exchange, trifoliate; handouts praise, 5-10 cm long, indirectly serrate, terminal pamphlet biggest; racemes 10 cm long; bracts slim, longer than blooms; blossoms rose-hued; cases 4-12 cm since quite a while ago, pointed, 5-15 seeds; seeds 3-5 x 3-4 mm, white, dim or dark.
Scientific name: Cyamopsis tetragonoloba
Common name: Guar or group bean
How to grow and maintain Cluster beans:
Clusterbean is a tropical plant. It requires warm developing season. The yield obliges 30 to 350 C temperatures at the sowing time for appropriate germination and 32 to 380 C temperature supports great vegetative development, however high temperature at blossoming stage can bring about pre-develop bloom drop. It can endure temperature as high as 45-460 C. It is a photosensitive and uncertain product. Air stickiness empowers the invasion of numerous illnesses like bacterial leaf curse, root spoil, and so forth.
Cluster beans can be developed in an assortment of soils. The product develops best on all around depleted, upland sandy topsoil and soil soils. It doesn’t flourish well on overwhelming and water logged soils. It likewise does not flourish well in saline and soluble soils. It can be brought effectively up in the dirts having pH 7 to 8.5.
Spacing is vital to guarantee that the plant can get appropriate supplements, dampness and light empowering its legitimate development. It includes intra and bury push separating. The suggested dividing is 10 – 15 cm remove between two plants in succession and a separation of 45-60cm column to push. The seeds utilized for this sort of separating is right around 14 to 24 kg for each hectare. The dividing thoroughly relies on upon precipitation and different variables. If there should be an occurrence of dry districts with precipitation of 200 – 350mm the column separation ought to be 60×10, in semi – bone-dry (450 – 500mm) it ought to be 45×10 and in the event of precipitation of 550-600 it ought to be 30×10.
Cluster beans being a leguminous yield, needs a little amount of nitrogen as a starter dosage amid early development period. Cluster beans requires 20 kg N and 40 kg P2 O5 per hectare. 2.5 Full measurement of nitrogen and phosphorus ought to be connected at the sowing time. It is prudent to take after incorporated supplement administration hones for cluster bean. Around 2.5 tons of fertilizer or FYM ought to be connected no less than 15 days before sowing. Utilization of FYM or fertilizer is helpful for enhancing water holding limit of the dirt and furthermore to supply every one of the supplements require for the plant development. At the sowing time, 10 kg nitrogen and 20 kg P2O5 ha-1 ought to be connected as basal measurements. Manure ought to be put no less than 5 cm underneath the seed. Seed vaccination with reasonable rhizobium strains and phosphorus solubilizing microorganisms (PSB) is valuable for expanding crop yield.
Since Cluster bean is a dry spell – tolerant harvest, it can be effectively developed in zones of 300 – 400 mm yearly precipitation. Waste is imperative for development of cluster bean as there may be formative harm because of water logging. Despite the fact that the efficiency of the product is upgraded by water system promptly in the wake of sowing, with change of the seed protein content. On the off chance that it is developed in ranges of high precipitation, water system won’t not be required. Trickle water system can be utilized for expanding the efficiency of group bean development.
Pests and Management:
The plants are also highly susceptible to various kind of pest manifestation. Most common are Leaf hopper, Ash weevils, Pod borer. There are various ways by which we can control pest manifestations:
Leaf Hopper: spray Dimethoate 30 EC 1ml/l of water or Methyl Demeton 1ml/l of water.
Ash Weevils: spray Phospholane 1.5 to 2.0ml/l of water .
Pod Borer: spray Quinalphos 2ml/l of water or Carbaryl 50 WP 2gm/l of water
