Distinct greengram variety

THE NEW greengram variety `VBN Gg2' is a short duration (65-70 days) type having moderate resistance to Yellow mosaic virus disease. The new variety was developed at National Pulses Research Centre, Vamban, Pudukkottai and released during January 2001 for cultivation.

It is a hybrid derivative of a cross between VGG 4 and MH 309, the new variety has registered, a higher seed yield over the ruling varieties namely CO5, CO6 and Vamban 1. For pod borers this culture recorded moderate resistance. The leaves are having lobed margin as a distinct character.

This variety is ideally suitable for cultivation throughout Tamil Nadu during all seasons. The crop can be grown during June-July, September-October and February-March.

Under irrigated condition twenty kilogram of seed and for rainfed condition, thirty kilogram of seed is required to cover an area of one hectare.

A spacing of 30 x 10 cm can be adopted to maintain the optimum population of 33 plants per m2. A nutrient dose of 25 kilogram nitrogen, 50 kilogram of phosphorous, 20 kilogram of potash for irrigated and 12.5 kilogram of nitrogen, 40 kilogram of phosphorous, 20 kilogram of potash under rainfed condition is prescribed.

Two hand weeding on 15th and 30th days after sowing or pre- emergence application of pendimethalin at 2 litres per hectare on 3rd day after sowing followed by one hand weeding on 30th day is recommended to avoid weeds, under irrigated condition.

During early stages under irrigated condition, spraying of dimethoate 30 EC or monocrotophos 36 WSC at 500 milliliter per hectare to control sucking pests is recommended. To control pod borers, spraying with endosulfan 35 EC 1000 milliliter per hectare is recommended.
