Recommended Domain:

This variety is recommended in non-irrigated upland areas (Pakhobari) of Mid-Hills of Nepal.

Cultivation Practices:

For the optimum production of turmeric, especial care from site selection to the market management is very essential. Ginger Research Center Kapurkot recommended the following technique of Turmeric Production technique:

Soil:

Soil rich in organic matter having Well drainage system, light in texture, loamy soil with high productivity is best for this crop. However, soil with high productivity with sandy loam to clayey soil is also better for this crop. The optimum pH of soil is 5.5-6.5.

Field preparation & manuring:

After the rain during the month of Falgun in Mid-Hills, field are tilled for 3-4 times to make soil light & porous mixing with FYM. The recommended dose of fertilizer for turmeric crop is 30: 30: 60 kg NPK/ha according to Research center Kapurkot. FYM is recommended as 30 ton/ha.

Seed Management:

Seed management must be given especial care as rhizome is used as seed in Turmeric which is required in large quantity. Breeder seed of this variety is available to Krishi Gyan Kendra and seed producing cooperative at farmers level by research center kapurkot.

Planting Time:

In Mid-Hills of Nepal, this crop can be planted upto the last week of Chaitra however, this especial variety is better when planted by first week of Chaitra.

Seed Rate & Spacing:

Generally, rhizome with 35-36 grams weight is preferred as seed rhizome for planting. The recommended spacing in turmeric is 30 cm between row to row and 25-30 cm between plant to plant i.e. (30 cm * 25-30 cm) at the depth of 5-7 cm. At this spacing it requires 150-175 kg rhizome per hector.

Mulching:

In case of turmeric, it is planted during Chaitra Baisakh in non-irrigated upland soil where moisture is minimum. So, mulching is essential for preserving the moisture of the soil in the field. Due to use of mulching, it conserves the soil moisture & helps in developing the plant for higher yield ultimately. It is essential to control weed growth, keep similar temperature in the field, prevent soil erosion, keep soil loose & structured, prevent damage of hailstorm & heavy rain. As ultimately, mulch decomposes in soil, it helps in adding the fertility to the soil. Khar, Paral, Sallako kusum, Dry leaves & hay are used as mulch according to availability in different region. Cover the field with mulch immediately after planting the crop.

Irrigation:

Since, turmeric is cultivated in non -irrigated upland condition in rainy season, irrigation is not so crucial. But according to soil moisture status, when there is no rain, irrigation is given at 3 weeks interval. Turmeric is susceptible to water stagnation so, drainage is must.

Weeding & Earthing up:

High amount of fertilizer is used in turmeric and as the plant growth is very slow during the initial stage, weed may compete with main crop at rapid rate for sunlight, fertilizer & moisture which will ultimately cause low yield. 2-3 weeding according to weed invasion and at top dressing of urea, weeding followed by earthing up is beneficial to avoid water stagnation.

Crop protection:

Use seed of areas free from diseases and should be treated before planting. As this crop is tolerant to leaf blotch disease, according to disease severity status during Bhadra month at 15 days interval, apply 1% Bordeaux mixture or Dithane M-45 @ 0.2-0.3% or Blitox 50 @ 3 gram/liter water. In this variety none of the pest has cause economic damage however, leaf roller, Stem borer, Scale insects etc. may invade which is controlled spraying Desis @ 0.1%.

Harvesting & Storage:

Turmeric is harvested when leaves turn yellow and starts to dry. Harvesting is generally done after 9-10 month of planting during Poush to Magh. In comparison to harvesting done at Mangsir & Falgun to Poush-Magh, the amount of Curcumin is higher by 15-18%. Remove the stem of the crop about 1 week earlier of crop harvesting. Avoid injury to rhizome during harvesting done with spade, removing diseased, decayed, pest attacked rhizome which are taken for storage. Due to high moisture content in turmeric (Besar), storage temperature is critical during storing crop otherwise which may lead to wrinkling, rotting, drying problem in rhizome. Temperature of 12-14 degree Celsius with 65-70% relative humidity is essential to maintain for storing turmeric. At farmer`s level, storing in pit, mud Bhakari etc can be used for storing turmeric safely.
