In India seed production is being done by well-developed seed plot technique.Growing seed potato crop during low aphid period with healthy seed from October to first week of January coupled with the use of insecticides, rouging and dehaulming in the last week of December or up to second week of January, was developed by the CPRI, Shimla and is called as “Seed Plot Technique” (fig). Benefits of Potato. Introduction • Seed Plot Technique is a raising healthy seed crop during low aphid period available in Northern Plains during Oct- Jan and cutting haulms and harvesting of crop. The field produce can be used as seed for at least 2 seasons in potatoes seed producing areas and for 1 season in other areas. Method of planting 6. The system uses 50% less land than the ware production to meet on-farm seed tuber requirements In order to obtain healthy & high yielding seeds, farmers need to focus on the following points: Calculate the required fertilizer for potato cultivation here. • This technique and effective viral diagnostics has sustained the National Potato Seed Production Programme by producing about 2600 tons of breeder’s seed annually. The resulting plot planter is a two-row implement that can be adjusted for individual row seed piece spacing and fertilizer rate settings. Likewise, CIP released in 2007 the paper … Thinning is essential after 20-25 days to maintain optimum plant population in the field. In this method smaller tubers are made in the nursery beds and these are used as seed tubers to raise the ware crops next season. It comprises three demonstration protocols: (i) crop husbandry, (ii) positive selection and (iii) small plot technique. Do not select those with virus or other disease symptoms. It is used for varieties of which no seed is produced in commercial seed programmes. Progress 07/01/91 to 09/30/12 Outputs OUTPUTS: Productivity achievements over the past several years in project experiments growing minitubers using nutrient film technique (NFT) have made it possible to raise a significant amount of acreage of first-field-generation (FY1) seed potatoes at the University of Wisconsin Foundation Seed Potato Farm by planting minitubers produced in NFT culture. Agriculture is an inseparable part of Nepalese economy and Nepalese people are devoted to Subsistence Agriculture. The process of seed potato certification involves field inspections throughout the growing season, to check for disease and to ensure that varieties are true to type, as well as a winter grow-out of the seed, to screen for disease contamination. It is the technique for virus free seed production. 1 Seed Production and Training Manual – by Lambert Delimini – FAO - 12/05/2012 PREFACE Plant breeding activities lead to the development and release of improved crop varieties. Conventional certified seed potatoes are initiated by clonal selection and the tuber unit technique on a primary foundation seed farm. The country has invested heavily in improving seed production techniques, but has yet to reach its goal. Unavailability of good qual-ity seed, high price and untimely supply of seed at the village level are the main limiting factors in potato production. Stake all plants needed at the same time, and only those of the same variety. Growing potatoes from true potato seeds is fun and you can discover some very good new varieties, but it is not as reliable as growing potatoes from tubers. A seed-plot technique has been developed on a pilot scale to increase on-farm availability of quality seed potato. The tuber is broken into pieces at planting time and placed sequentially in the slots of a rotating wheel, with a skip between tubers. The conventional seed production technology based on “seed plot technique” is successfully being used in India since last five decades for quality potato seed production. Germination take place in 15 days. In the levelled nursery beds, 2-3 grams TPS is dibbled at 10 cm * 10 cm spacing at a depth of 0.5-1 cm.
