“…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.…”

Evaluation of In-Row Plant Spacing and Planting Configuration for Three Irrigated Potato Cultivars

et al. 2011

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.

“…They found that total tuber yield did not respond to increased plant population. Lynch and Rowberry (1977) found that LAI in the early vegetative and tuber initiation growth stages increased with plant population. The negative correlation between PAR and tuber size found in this study is largely the result of a negative relationship between plant population and tuber size as intercepted PAR (i.e., LAI) in the early vegetative and tuber initiation growth stages is directly related to plant population.…”

“…1) due to a narrower in-row plant spacing to reach a given plant population compared to the bed planting configurations, which resulted in a lower average tuber size. Average tuber size was found to decrease with plant population by Lynch and Rowberry (1977) who studied the effect of plant population (44,000 to 110,000 plants ha −1 ) on Russet Burbank yield using a square planting arrangement (equal in-row and between-row spacing). They found that total tuber yield did not respond to increased plant population.…”

Effects of Planting Configuration and In-Row Plant Spacing on Photosynthetically Active Radiation Interception for Three Irrigated Potato Cultivars

Research studies have evaluated the production of potatoes (Solanum tuberosum L.) grown in conventional and bed planting configurations. However, intercepted photosynthetically active radiation (PAR) from these planting configurations has not been quantified. planting (DAP) was increased 35%, 38%, and 32% for the 5RB and 65%, 69%, 23% for the 7RB relative to the 4RC planting configuration for Ranger Russet, Ranger Norkotah, and Russet Burbank, respectively. Cumulative PAR interception for the season was increased 15%, 16%, and 4% for the 5RB and 23%, 23%, 5% for the 7RB relative to the 4RC planting configuration for Ranger Russet, Ranger Norkotah, and Russet Burbank, respectively. The relationship between intercepted PAR and leaf area for Russet Norkotah during the early vegetative and tuber initiation growth stages was significantly different between the three planting configurations, with intercepted PAR at a given leaf area in the order of 7RB>5RB>4RC. For Russet Burbank, the relationship was significantly different for the 5RB and 7RB compared to 4RC planting configuration only, with intercepted PAR at a given leaf area in the order of 7RB05RB>4RC.

ROBERTO DOS ANJOS REIS JÚNIOR 2 e PAULO CEZAR REZENDE FONTES 3RESUMO -Com o objetivo de avaliar o efeito de época de amostragem e da adubação potássica sobre a morfologia e partição de assimilados na batateira (Solanum tuberosum L.), foram realizados dois experimentos no campo: o primeiro para avaliar o efeito de doses da adubação potássica e o segundo para avaliação do seu efeito residual. Foram aplicadas seis doses de K no campo (0, 60, 120, 240, 480 e 960 kg de K 2 O ha -1 ) na forma de sulfato de potássio, em delineamento de blocos casualizados, com quatro repetições. Tubérculos da cultivar Baraka, uniformemente brotados, foram plantados em espaçamento 0,8 x 0,3 m. Amostraram-se plantas aos 20 e 48 dias após emergência (DAE) para avaliação de área foliar, comprimento de caule, números e produções de matéria fresca e seca de folha, caule e tubérculo e teores de matéria seca de folha e caule. Apenas o comprimento de caule aumentou com as doses de K, resultando em menor sombreamento da batateira. No primeiro experimento, aos 20 DAE, a batateira apresentava, em média, 42 folhas, três hastes, 5.389 cm 2 de área foliar, 157,1 e 216,4 g de matéria fresca de caule e de folha, respectivamente, e 6,2 e 9,2% de teor de matéria seca de caule e de folha, respectivamente.Termos para indexação: Solanum tuberosum, nutrição mineral, produção de matéria fresca, produção de matéria seca. POTATO MORPHOLOGY AND DRY MATTER PARTITION IN RESPONSE TO SAMPLING TIME AND K LEVELSABSTRACT -This study was conducted in order to evaluate potato (Solanum tuberosum L.) morphology and dry matter partition in response to sampling time, K levels and its residue. Six K levels (0, 60, 120, 240, 480 and 960 kg K 2 O ha -1 ) were applied in the field as potassium sulfate, in randomized blocks design, repeated four times. Baraka potato tubers were seeded spaced 0.8 x 0.3 m. Plants were sampled at 20 and 48 days after its emergence (DAE) to estimate leaf area, stem length, number and fresh and dry matter yield of leaf, stem and tuber, and dry matter content of leaf and stem. Only stem length increased with K fertilization, resulting in smaller overshadow of plant. In the first experiment, at 20 DAE, potato was presenting, in media, 42 leaves, three stems, 5,389 cm 2 of leaf area, 157.1 and 216.4 g of fresh matter of stem and leaf, respectively, and 6.2 and 9.2% of dry matter content of stem and leaf, respectively.
