“…In our study, decreasing in-row plant spacing increased tubers per ha, the inverse of the relationship between in-row plant spacing and average tuber size. The results of this study are consistent with those of Rykbost and Maxwell (1993) who found no significant difference in total or U.S. No.1 tuber yield of Russet Norkotah or Ranger Russet potatoes over a plant population ranging from 41,152 to 72,621 plants ha −1 . The effects of plant population on average tuber size found in this study are consistent with the results of Lynch and Rowberry (1977) who found average tuber size to decrease with increasing plant population as a result of various in-row and between row plant spacings (planting architecture).…”

“…Field studies investigating the effect of plant population on potato yield have been conducted in North America under both irrigated (Iritani et al 1972;Lynch and Rowberry 1977;Davis and Groskopp 1979;Rykbost and Maxwell 1993;Love and Thompson-Johns 1999) and non-irrigated (Entz and LaCroix 1984;Rex 1990;Nelson 1967;White and Sanderson 1983;Rex et al 1987;Rex 1991) conditions. Most of the studies investigated the effect of in-row spacing only, however, with the exception of Lynch and Rowberry (1977), which also included between row spacing as a population variable.…”

“…In general, however, higher plant populations result in lowering average tuber size. Rykbost and Maxwell (1993) Optimum plant populations in bed planting configurations have not been determined for potato cultivars commonly grown in the Pacific Northwest. Plant population is important when planting in bed configurations due to the increased opportunity to manipulate plant population to target a specific tuber size market.…”

Research studies have shown that planting potatoes (Solanum tuberosum L.) in a bed configuration can improve water movement into the potato root zone. However, plant spacing recommendations are needed for potatoes planted in a bed configuration. This study was conducted to evaluate the effect of in-row plant spacing and planting configuration on yield of Russet Burbank, Russet Norkotah, and Ranger Russet potatoes under sprinkler irrigation. For the three cultivars, the effect of in-row plant spacing (three spacing treatments) for each planting configuration (4 row conventional ridged-row [4RC], 5 row bed [5RB], and 7 row bed [7RB]), and the effect of planting configuration at a uniform population on total tuber yield, U.S. No. 1 tuber yield, tubers per ha, average size (by weight), and large tuber yield were investigated at the USDA-ARS Northwest Irrigation & Soils Research Lab in Kimberly, ID on a Portneuf silt loam (coarse-silty mixed mesic Durixerollic Calciorthid) in 2008 and 2009. The greatest influence of in-row plant spacing was on average size and tubers per ha. In general, as in-row plant spacing increased (plant population decreased) the average tuber size increased and tubers per ha decreased. There was little influence of in-row spacing on measured production variables under the bed planting configurations except for tubers per ha which generally increased with narrower plant spacing. For Russet Norkotah and Ranger Russet there were few differences in measured production variables between planting configuration treatments. For Russet Burbank, the 4RC planting configuration had 14.6% significantly greater total tuber yield than the 7RB planting configuration, 20.2% greater U.S. No. 1 tuber yield than both bed planting configurations, and 25.2 and 29.9% greater large tuber yield than the 5RB and 7RB planting configurations, in 2009. Optimum production of Russet Norkotah and Ranger Russet potatoes is possible under all the planting configurations and plant spacing range evaluated in this study, granting growers flexibility in their systems, however, evidence from this study suggests that production of Russet Burbank may be less suited to bed planting configurations.Resumen Investigaciones han demostrado que plantar papa (Solanum tuberosum L.) en una configuración de cama puede mejorar el movimiento del agua hacia la zona de la raíz de la papa. No obstante, se necesitan las recomendaciones de espaciamiento de plantas de papa sembradas en la configuración de cama. Este estudio se condujo para evaluar el efecto del espaciamiento entre plantas en el surco y de configuración de plantación en el rendimiento de papa Russet Burbank, Russet Norkotah, y Ranger Russet bajo riego por aspersión.

Planting System Effect on Yield Response of Russet Norkotah to Irrigation and Nitrogen under High Intensity Sprinkler Irrigation

et al. 2010

Conversion of potato ridged-row planting systems to wide bed planting systems may increase water and nitrogen use efficiency in commercial irrigated potato production systems by reducing the amount of irrigation water and water applied nitrogen fertilizer bypassing the potato root zone. Wide bed planting systems consist of planting multiple rows on a wide bed with 20 to 35% higher plant population than found in conventional ridgedrow planting systems. The objective of this study was to evaluate the effect planting system has on yield response of 'Russet Norkotah' potato to irrigation and nitrogen. Planting systems evaluated were (1) conventional ridgedrow with dammer-diking; (2) 3.7 m wide bed with five potato rows spaced 66 cm between adjacent rows centered on the bed and; (3) 3.7 m wide bed with seven potato rows spaced 46 cm between adjacent rows. Six irrigation amounts, 50, 70, 85, 100, 115, and 130%, of estimated evapotranspiration after tuber initiation and four nitrogen rates, <20, 50, 100, and 150%, of conventional recommendations were applied to the three planting systems. Interactions between irrigation amounts and nitrogen rate were significant for total and U.S. No. 1 yield, irrigation water use efficiency, and gross return in one or both study years. Interactions between nitrogen rate and planting system were significant for total and U.S. No. 1 yield, irrigation water use efficiency and gross return in the first year of the study. Interactions between irrigation amount and planting system were not significant. In the first study year, total and U.S. No. 1 yields were significantly increased 12 and 19 percent, respectively, under the 7-row bed planting system compared to ridged-row planting system. Comparison of ridged-row planting system and 5-row bed planting system on 31 commercial potato fields in eastern Idaho representing a combined area of 2,800 ha over 5 years resulted in significantly higher total yield and irrigation water use efficiency with the bed planting system. The 5-row bed planting system averaged 6% higher total yield, 5% less water application and an 11% increase in irrigation water use efficiency. The results of this study demonstrate that under high intensity rate sprinkler irrigation in the soil and climatic conditions prevalent in eastern Idaho, bed planting systems provide viable production alternatives for irrigated potato production that may increase total yield, gross return, and irrigation water use efficiency.Resumen La conversión de los sistemas de plantación de papa de surco simple a cama ancha puede incrementar la eficiencia en el uso de agua y nitrógeno en sistemas de producción comercial de papa bajo riego, mediante la reducción de la cantidad de agua de riego y del fertilizante nitrogenado aplicado en el agua que penetra hasta la zona radical de la papa. Los sistemas de plantación de cama ancha consisten en plantar hileras múltiples en una cama amplia con una población de plantas de 20 a 35% mayor que los encontrados en los sistemas convencionales de surc...

SummaryExcessive fertilizer application in North Carolina, USA results in high residual soil levels of P, K and total soluble salts in potato fields. Our objectives were to determine the salt sensitivity of three common cultivars (Atlantic, Snowden and Superior), and the effects of planting density and fertilization on stand establishment, soilborne disease, and yield. Greenhouse results suggest that potato growth and emergence, but not shoot initiation, are reduced by high salinity. On a Portsmouth fine sandy loam, high fertilizer rates did not reduce stands of cv. Atlantic in the field in 1996 or 1997. Excess N resulted in more Rhizoctonia stem canker in 1996, and lower yields at the lower planting density in 1997. Yield compensation for reduced plant density occurred in 1997 at the lower N rates (56 and 112 kg N ha -l) and at the high PK rate (49 kg P and 139 kg K ha-l).
