“…When the vertical distance was greater than 10 cm and the lateral distance greater than 20 cm, tubers over 80 g were significantly reduced under Southwest China conditions (Zheng et al, 2016). For getting higher proportion of seed size tubers (25-125 g), 15 cm intra-row spacing×70 days haulm killing×120 kg N was found to be most suitable combination in seed production system of early bulking cultivar Kufri Khyati (Sadawarti et al, 2017). Highest percent of 31% medium size tubers (40-55mm) were recorded in 60×20 cm 2 spacing under Srilankan conditions (Rajadurai, 1994).…”

“…Narrow in-row spacing (15 cm) and moderate N fertility levels (200 kg ha -1 ) shifted the tuber size distribution towards the smaller size ranges (30-45 mm) Waterer, 1997. Medium dose of 100 N: 120 P 2 O 5 : 60 K 2 O kg ha -1 recorded 58% of 20-80 g tuber size with highest net return (Singh, 1999). 15 cm intra-row spacing×70 days haulm killing×120 kg N recorded highest seed size tuber number (432 thousand ha -1 ) and found to be most suitable combinations in seed production system of Kufri Khyati under Gwalior condition of Madhya Pradesh (Sadawarti et al, 2017). Reduction in intra row spacing from 20 to 15 cm, dehaulming at 65 DAP and decrease in nutrient levels from 100% RD of NPK (200;100:150 kg ha -1 ) to 50% RD of NPK, seed grade size (25-50 and 50-75 g) tuber yield and numbers and total tuber numbers were increased significantly in Kufri Himalini under West Bengal conditions of India (Das et al, 2020).…”

“…Percent production of seed size tubers to total tubers (both on weight as well as number basis) was higher at narrow intra row spacing (Singh and Singh, 2016). Sadawarti et al, 2017 reported that significantly higher seed (25-125 g) size (405000 ha -1 ) tuber number with closer intra row spacing of 15 cm over 20 cm intra-row spacing (337000 ha -1 seed size). Medium-sized seed tubers (40-75 g) increased as spacing reduced, closer spacing of 50 cm×25 cm 2 and 60×25 cm 2 produced higher tuber number m -2 over wider spacings of 80×30 cm 2 and 75×30 cm 2 (Binalfew et al, 2015).…”

“…In India, it ranges from 40 to 50% (Beata et al, 2020, Chakraborty et al, 2013, Venkataselam et al, 2011. The situation is further aggravated in high bulking cultivars Kufri Sutlej which has tendency to produce more numbers of over size tubers (Sharma et al, 2001) and Kufri Khyati which produces up to 50% under and over size tubers (Sadawarti et al, 2017 and2021a). Seed cost actually depends on seed size and intra-row spacing (Islam et al, 2012).…”

The seed potato cost is very important component in total potato production and account for 30 to 70% which varies depending on the country or region. Tuber size is an important factor to decide the seed requirement per unit area. Seed size affects total yield, graded or marketable tuber yields. Standard seed tuber of 25–125 g weight (30–55 mm) is known as seed size tubers in India. Obtaining seed size tuber is important for achieving higher potential of the cultivars. The tuber size profile can be reduced or expanded by altering inter and intra row seed spacing, controlling days of growth by planting late or killing vines/haulm early, regulating inputs like fertilizer and water etc. An ideal combination of plant population, row width, and in-row seed spacing for a particular variety were the major factors for optimizing tuber size. Variation in tuber bulking ability in different genotypes results in variation in proportion of seed size tubers among different varieties. 70–80 days haulm killing found most suitable for getting higher proportion of seed size tubers in high bulking varieties. Proper management of N, P and K fertilizers is considered very important to maximize tuber yield and attain desirable quality. Variability in nitrogen dose/ha was observed which ranged from 100–150 between different regions of the world. Hence proper combination of above Agro-techniques should be adopted in seed production programme as per the region for getting higher proportion of seed size/plantable seed tubers.

“…A good rule is to keep the number of cut surfaces per tuber to a minimum. Factor combinations of days to haulm cut and row spacing along with size of seed tubers/pieces plays important role in grade wise and total yield potential of a variety (Sadawarti et al, 2017). Keeping above points in view, a field experiment was planned to evaluate date of haulm cutting, different size of cut and whole seed tubers and intra row spacing.…”

The field experiments were conducted during two consecutive rabi seasons (October – February) during 2019–20 and 2020–21 at ICAR-Central Potato Research Institute Regional Station, Gwalior, Madhya Pradesh, India located in west central plains of India. Highest emergence of potato plants was recorded with the planting of 40 g whole tubers. Growth attributes viz. plant height (58.6 cm) and number of compound leaves (56.7) were recorded highest with 40 g seed piece/whole tuber. Planting of 120 g seed tubers, 10 cm intra row spacing and 114 days haulm cut recorded highest number of small tubers i.e. 3,43,000 ha-1, 3,07,000 ha-1 and 3,26,000 ha-1, respectively. Highest total number of tubers was recorded at 114 DAP haulm cut (9,08,000 ha-1), planting of 120 g seed tubers (9,62,000 ha-1) and 10 cm intra row spacing (8,53,000 ha-1). Highest total tuber yield was recorded with 114 DAP haulm cut (59.1 t ha-1), 120 g planted seed tubers (55.5 t ha-1) and 20 cm intra row spacing (49.7 t ha-1). Highest cost of cultivation was recorded with the use of 120 g seed (Rs. 386483 ha-1) and intra row spacing of 10 cm ` 264261 ha-1. Highest net return (Rs. 364084 ha-1) was recorded with 114 DAP haulm cut, planting with 40g seed size tubers (` 329822 ha-1) and intra row spacing of 20 cm (Rs. 322499 ha-1). Highest benefit-cost ratio was recorded with 114 DAP haulm cut (2.6) planting with 20 g seed size tubers (3.3) and intra row spacing of 20 cm (2.8).

Potato (Solanum tuberosum L.) varieties, viz. Kufri Lauvkar (early maturing), Kufri Gaurav and Kufri Jyoti (medium maturing) were examined during the years 2018–19 and 2019–20 for the seed size tubers production with 3 dates of haulm killing, viz. 70, 80, and 90 days after planting under West-Central Indian conditions at ICAR-Central Potato Research Institute, Regional Station Gwalior, Madhya Pradesh. Haulm killing at 80 (15.05 t/ha) and 90 days (14.60 t/ha) noticed significantly greater seed size tubers weight over 70 days' haulm killing (12.13 t/ha). Kufri Gaurav recorded substantially greater number of seed size tuber (288 t/ha) and weight (15.76 t/ha) than the other two varieties. Eighty days haulm killing was observed to be the best seed significantly: non-seed ratio (1.088 by numberand 0.659 by weight) followed by 70 days (1.140 by number and 0.734 by weight) over the poorest 90 days haulm killing (1.121 by number and 0.946 by weight). Therefore, for achieving high seed-size potato tubers, haulm cutting should be done at 80 DAP.
