Breeding taro by tissue culture method

Ninh Binh province is applying tissue culture method to propagate native taro in order to take the initiative in clean seed sources to meet production needs. Potatoes are piloted in Yen Quang Agricultural Cooperative, Nho Quan District.

Compared to traditional varieties, taro tissue culture has a faster growth rate, high yield, stability and consistent with local soil conditions.

Mr. Hoang Trong Le, Director of the Center for Applied Science, Technology and Measurement of the province said that if applying the technical process correctly, taro growers could gain profit of 130 million VND / ha, higher than 30 million VND / ha compared to ordinary taro bulbs.

The expansion of taro model by tissue culture technology is feasible because it not only contributes to developing a commodity area but also brings economic benefits to farmers.

People who want to grow potato cultivating tissue need to apply proper technical measures. Planting soil should be plowed carefully, pick up clean grass then dig triangular holes, each new 20cm side will sow tubers, each bulb is 40cm apart, every 70cm from the row. Fertilizer level for 1ha consists of 2 tons of manure, 220kg of urea nitrogen, 470kg super phosphate and 165kg of potassium chloride. Initially, growers fertilize all manure and 2/3 of phosphate. When the plant has 3 leaves, the first time is applied with 1/2 of protein, 1/3 of the amount of potassium chloride combined with weeding, cultivating soil.

After 60 days of fertilizing with nitrogen, remaining phosphorus and 1/3 of potassium. The plant grows for 120 days with the remaining amount of potassium fertilizer combined with high root for potato roots. When fertilizing, apply 10cm from the root, not too deep or too far from the root. During the period of 5 to 6 leaves, it is necessary to avoid drought which will affect productivity. Before harvesting 1 to 2 months, limit watering and stopping to completely turn starch.

Taro is the main crop in winter crop in Nho Quan district. However, according to the assessment of the Chairman of Yen Quang Agricultural Service Cooperative Quach Dinh Liep, the expansion of this plantation area is limited due to the traditional method of propagation of the people mainly by the root of the family. The households choose after each harvest so the seed quality is not high, not enough to meet production needs.

Since the application of this method, the plants not only clean the disease, reduce the cost of pesticides and fertilizers during cultivation but also put the number of good quality potatoes to make the seed twice as high as when Apply common potato cultivation.

In the coming time, Yen Quang Agricultural Cooperative will plan a concentrated taro production area to facilitate the care and application of science and technology, improve economic efficiency.
