Drip Fertigation: A Tool for higher Yield, Water and Nutrient Use Efficiency

Tobacco as a commercial crop has unique place in India, as it generates substantial amount of about Rs 23,318 crores to the national exchequer in terms of excise revenue and foreign exchange of Rs 6058 crores. Tobacco is grown under different agro-climatic conditions viz., monsoon and also in post rainy season under conserved soil moisture. […]

Poly Tray Seedling Production

A tray nursery technique has been developed and standardized to produce healthy tobacco seedlings to overcome disease problems and to preclude transplantation shock. The technique is simple and entails sowing tiny tobacco seeds on coconut coir pith compost and transferring the young seedlings of about 20-25 days to poly-trays for raising them on the growth […]

Conventional Seedling Production

Ideal soils (Well drained light textured soils, with low soil chlorides (< 100ppm)) is a prerequisite for successful nursery raising. Pre-sowing operations viz., deep ploughing, bed cutting and post sowing operations viz., mulching, regular watering (4 times a day) and weeding, pest and disease control measures are essential in conventional nursery which is costly and […]

TOBACCO NURSERY MANAGEMENT 5

Seedlings of pencil thickness and of 10 to 15 cm length normally are preferred. Short seedling may establish well under optimum conditions in heavy soils. In light soils longer seedlings are preferred for planting. Normally, the seedlings are ready for planting at the end of 7th week and in the first picking 30 to 40% […]

TOBACCO NURSERY MANAGEMENT 4

Covers are gradually thinned or removed from the day when the seedlings appear on the surface as otherwise the seedlings may become etiolated and lanky for want of sunlight. It is also advantageous to transplant the seedlings from one to another bed i.e., resetting, when they are 3 to 4 weeks old in order to […]

TOBACCO NURSERY MANAGEMENT 3

In order to prevent the seedlings from desiccation due to intense heat and beating rains, under Dinhata conditions bamboo mats or jute-stick covers are placed directly on the beds while in Pusa the seed beds are covered with grass thaties or dry grass spreads. At Hunsur, paddy-straw covering was found to give adequate protection to […]

TOBACCO NURSERY MANAGEMENT 2

It is desirable to change the nursery site every year as it would minimise incidence of pests and diseases and also eliminate contamination by other varieties. If it is not possible to change the site, old site can be used after sterilizing by rabbing, i.e. by burning any readily available slow-burning waste-materials like, tobacco-stalks, paddy-husk, […]

TOBACCO NURSERY MANAGEMENT 1

Generally tobacco nurseries are grown on sandy or sandy loam soil. The cigarette-tobacco growing areas of Andhra Pradesh are an exception in that the crop is grown on a heavy black soil and the nurseries are generally raised on sandy to gravely loams. Raising of nurseries on heavy black soils is hazardous due to poor […]
