“…This may be due to these plants having more opportunity to obtain sufficient nutrients and moisture due to less resource competition, which may have favored greater levels of vegetative growth compared with plants that were grown with narrower inter-row spacings. This is consistent with the findings of Akassa et al (2014) who showed that plants grown at the widest spacing were significantly taller than those grown at the closest spacing.…”

“…This finding is possibly due to this trait being controlled by genetic rather than environmental factors. Similarly, Akassa et al (2014) and Darvishi et al (2015) also found that the specific gravity of tubers was not affected by plant density. Good-quality potatoes should have a specific gravity of > 1.08 g m -3 , with values of < 1.07 g m -3 generally being considered unacceptable for processing (Kabira & Lemaga, 2006).…”

Plant density affected yield, quality and water use efficiency. Little information describing plant density to optimize yield and quality of potato production is available in the Jordan Valley. This study was aimed to investigate the effects of plant density on the yield and yield components of the potato (Solanum tuberosum L.) cultivar “Spunta” grown in the middle of the Jordan Valley. Five different densities of plants (41,600 plants ha-1 (D1), 56,000 plants ha-1 (D2), 83,200 plants ha-1 (D3), 28,000 plants ha-1 (D4), and 41,600 plants ha-1 (D5) were randomly distributed over five replicate sites during the growing season from November 2013 to March 2014. Plant height, number of branches, fresh and dry weight of potato plants, tuber number, tuber weight, total yield, specific gravity and water use efficiency of potato plant grown under different plant density were measured. It was found that the productivity of potato increased with increasing plant density, with the highest total, marketable, and non-marketable yields being obtained at densities of 83,200 seeds ha-1, and the lowest occurring at 41,600 seeds ha-1, which equated to total fresh yields of 45.1 and 25.3 tons ha-1, respectively. The highest water use efficiency for marketable yield (11.9 kg m-3) was obtained at a density of 83,200 seeds ha-1, whereas the lowest water use efficiency (7.5 kg m-3) was obtained at a density of 41,600 seeds ha-1. The specific gravity ranged from 1.04 to 1.08 and the average tuber weight ranged from 77.02 g at a density of 83,200 seeds ha-1 to 115.84 g at a density of 28,000 seeds ha-1.

“…While the widest planting distance (80 cm x 25 cm) tends to produce the higher tuber weight per plant (171.31 gram) and tuber weight per plot (2.81 kg) (Table 02). This is due to the planting distance (80 cm x 25 cm) that has a better availability of nutrients, water and sunlight during plant growth thereby increasing tuber weight per plant and tuber weight per plot (Akassa et al, 2014)65, 70, 75, 80 and 85 cm and three levels of intra row spacings: 20, 30 and 40 cm. According to (Bani-Hani et al, 2018)quality and water use efficiency.…”

“…The low population provides an advantage to the individual plants in access to water, nutrients and sunlight. The regulation of planting distance is the important aspect of potato production management because it affects the total cost of seed, growth, development, yield and quality of crop (Akassa et al, 2014)65, 70, 75, 80 and 85 cm and three levels of intra row spacings: 20, 30 and 40 cm.…”

Purpose : The availability of quality potato seed is one of the limiting factors to improve the yield and quality. The aim of this research was to obtain the second generation of potato seeds (G2) with the best growth and yield in combinations the sources of shoot cuttings and planting distance. Research Method : The experiment used a factorial randomized complete block design with two factors: the sources of shoot cuttings (plantlet , G0, G1) and planting distance (80 cm x 15 cm, 80 cm x 20 cm and 80 cm x 25 cm) with three replications and the measured responses are component of growth and yield. Findings : The results showed that the sources of shoot cuttings from G0 produced the highest percentage of growth (97.72%), plant height (81.68 cm), canopy width (33.87 cm), maximum tuber weight per plant (237.27 gram), maximum tuber weight per plot (4.15 kg) and the highest number of tubers per plant (7.88) was obtained from the shoot cuttings sources of plantlet. Planting distance (80 cm x 25 cm) tends to be better for tuber weight per plant (171.31 gram) and tuber weight per plot (2.81 kg). Limitations : By using the shoot cuttings sources from plantlet it requires time to acclimatization. Value : It is very important to evaluate of shoot cuttings sources (plantlet, G0, G1) and planting distance so to accelerate the availability of G2 potato seeds in large quantities and quality, besides, using the shoot cutting sources can reduce production cost. The regulation of planting distance is the most important aspects of potato production.

“…Potato tuber size and different intra-row spacing were suggested in the production of good quality potato tubers in different parts of Ethiopia [14]. Seed tuber size of 45-55 mm diameter (90 g) was suggested for ware potato production at Adet Agricultural Research Center [15].…”

A field experiment was conducted at Nono Benja District from December 2013 to May 2014 under irrigation to assess the response of different sizes of seed tubers and intra-row spacing on the yield and quality of potato varieties. The treatments consisted of a factorial combination of two varieties (Jalenie and Gudenie): five levels of tuber size (20–35, 36–50, 51–65, 66–80, and 81–95 g) and five levels of intra-row spacing (20, 25, 30, 35, and 40 cm). The treatments were arranged in a split-split plot design (variety on main plot, intra-row spacing on subplot, and tuber size on sub-sub plot) with three replications. There were significant interaction effects of variety, intra-row spacing, and tuber size ( P < 0.05 ) on plant height, number of main stems per plant, average tuber weight, tuber number per plant, total tuber yield, marketable tuber yield, unmarketable tuber yield, large tuber mean yield, medium tuber mean yield, and small tuber mean yield. Variety of tuber size and intra-row spacing was also influenced by dry matter content and tuber specific gravity. The interaction effect of intra-row spacing and seed tuber size was significantly ( P < 0.05 ) influenced by the number of days to emergence. The day to flowering was also significantly ( P < 0.05 ) influenced by the interaction effect of variety and intra-row spacing. The maximum plant height (80.38 cm) was recorded with variety Gudenie with a tuber size of 66–80 g and planted at an intra-row spacing of 35 cm. The maximum (9.79) number of main stems was recorded in variety Jalenie with a tuber size of 81–95 g and planted at intra-row spacing of 40 cm. The maximum of total tuber yields (24.84 to/ha) was recorded from Jalenie variety with tuber size 66–80 g and planted at intra-row spacing of 25 cm. The maximum (10.18 t/ha) larger tuber was recorded with variety Gudenie with a tuber size of 66–80 g and planted at 25 cm. Variety Jalenie with tuber size of 66–80 g and planted at 25 cm produced the maximum (8.04 t/ha) medium-sized tubers. The maximum small tuber (8.59 t/ha) was recorded from both varieties with intra-row spacing of 20 cm and tuber size 81–95 g. Variety Gudenie planted at intra-row spacing of 40 cm gave higher (19.98%) dry matter content, and variety Gudenie with a tuber size of 66–80 g gave higher (20.61%) dry matter content. The higher (1.077) tuber specific gravity was obtained with variety Gudenie planted at intra-row spacing of 35 and 40 cm, and the higher (1.074) tuber specific gravity was registered with variety Gudenie with a tuber size of 66–80 g and/or 81–95 g and planted at intra-row spacing of 40 cm. The study needs in-depth investigation by repeating in multilocations with more seasons, varieties, processing quality, and other agronomic practices of the crop to reach a conclusive recommendation. The result of this research was presented to Jimma University since 2015.
