Taro plantation

Hello sir,
1.Nitrogen at 100 kg N/ha is often applied as urea or ammonium sulphate, in split applications at 5, 10 and 15 weeks after planting (WAP). Where necessary, 25 kg/ha phosphorus is applied at planting as superphosphate. If potassium is low, 100 kg/ha is split, with one application at planting and the other at 10 WAP
2.From planting to harvest ranges from 5-12 months for dryland taro and 12-15 months for flooded taro
3.Harvest qty: 12600kg per hectare (12.6 tonnes per ha)

Hi Victoria,
There are two main production systems used in taro cultivation:
i) Flooded or wetland taro production
ii) Dryland (unflooded) or upland taro production
Growing taro under controlled flooding has several advantages over normal dry-land taro production:
a) The corm yields are much higher (about double)
b) Weed infestation is minimised by flooding
c) Out-of -season production is possible, often resulting in very attractive prices for the taro.
Dry-land taro is essentially rain-fed. Sprinklers or furrow irrigation may be used to supplement the rainfall, but the objective is mainly to keep the soil moist, not to get the field flooded.
The rainfed nature of dry-land taro cultivation means that the time of planting is critical. Planting is usually done at the onset of the rainy season, and the rainy season itself must last long enough (6-9 months) to enable the taro crop to mature.
The specific fertilizer types and quantities recommended vary widely from place to place; they are therefore left till the next section where cultivation practices in various countries are discussed. In general, it is best to apply the fertilizer, compost or manure as a split dose. The first portion is applied at planting, possibly incorporated into the soil during land preparation. This first dose promotes early plant establishment and leaf elaboration. The second dose is supplied 3-4 months later when the corm enlargement is well under way. Splitting the fertilizer dose minimises the effects of leaching which is potentially high in the high-rainfall areas where taro is produced.
Taro is able to form mycorrhizal associations which promote phosphorus uptake. Also, in some flooded taro fields, Azolla is deliberately or inadvertently cultured in the field water, thereby improving the nitrogen supply to the taro.
For dryland taro, maturity for harvest is signalled by a decline in the height of the plants and a general yellowing of the leaves. These same signals occur in flooded taro, but are less distinct. Because of the continuous and abundant water supply, the root system of flooded taro remains alive and active, and leaf senescence is only partial.
Time from planting to harvest ranges from 5-12 months for dryland taro and 12-15 months for flooded taro. Much depends on the cultivar and the prevailing conditions during the season.
Harvesting is most commonly done by means of hand tools. The soil around the corm is loosened, and the corm is pulled up by grabbing the base of the petioles. For flooded taro, harvesting is more tedious because of the need to sever the living roots that still anchor the corm to the soil. Even in mechanised production systems, harvesting is still mostly done by hand, thereby increasing the labour and cost of production.
Average yield - 10-12 tonnes/ha
