Abstract
Field experiments were conducted to determine the conditions for mint cultivation, after rice-vegetable(s), rice-potato, rice-legume and rice-wheat crop sequences, in the northern Indian plains.
Varieties, date of planting and density of two months old nursery raised plantlets, and N- fertilizer amounts were the variables.
About 90 days old transplanted crop of the mint variety Kalka obtained with 2.5 x 105 plants and applied with 160 kgN/ha gave an essential oil yield of about 164 kg/ha (about 55% of that of the normal duration crop of the highest yielding variety Himalaya). The late crop of the foot growing variety Gomti could be harvested twice.
The leaf: stem ratio was observed to be a dependable morphological indicator of herbage maturity in the mint crops.
The leaf: stem ratio for a minimum essential oil yield of about 130 kg/ha varied from 1.0–1.5 for different varieties.
It was concluded that the late transplanting schedule of mint cropping can save at least three months and thus allows taking of food crops such as mustard, potato, grain legumes, onion, garlic and wheat in the same field prior to mint.
Cultivation of one or more food crop in between rice and seedling transplanted mint can benefit food production and bring to the farmer higher levels of profit/hectare than those accruing from rice-sucker planted mint.
