“…The benefits from preplant ripping along the row, which are reported in the literature (Bishop and Grimes, 1978) were not observed in the Declo loam. Apparently rooting conditions were not limiting enough to benefit from the ripping.…”

“…Studies have been done on aeration and root growth of various crops (12,13,14,16). Particularly in the case of the potato, work has been done on the effects of various physical conditions on the rooting depth (1,10). Some work has been done on the effects of soil conditions around the tubers, though most studies involved observations of air permeability or bulk density of the soil as a result of various methods of compaction or cultivation (6,19,20).…”

On a Declo loam, rooting density, final yield and quality of potatoes (Solanum tuberosum cv. Russet Burbank) showed no significant differences among conventional planting, ripping along the row, or forced aeration 30 cm below the top of the row. There were significant relationships between oxygen diffusion rate (ODR) and soil moisture tension (matric potential) at the 30 and 40 cm depths, but these relationships were not significantly different among treatments.In a complementary experiment, sprinkler irrigations at negative soil water matric potentials of 30-40 (wet), 40-50 (intermediate) and 50-60 kPa (dry, i.e., 0.5-0.6 bar tension) produced no differences in total yield. However, the wet treatment gave significantly more knobby and undersized tubers < 113 g (4 oz.) and a lower percentage of U.S. #1 tubers than the intermediate and dry treatments. Premium sized tubers > 284 g (10 oz.) were significantly higher in the dry than in the wet treatment. Fertilizer N was applied periodically during the season and petiole NO 3-N levels indicated adequate levels with no differences among treatments in either experiment.So much attention has been given to the effects of drought and high temperature stress on the quality of Idaho Russet Burbank potatoes, that some growers may now over-irrigate. Results of this research indicate that attention should also be directed to the effects of excess moisture on the size and quality of tubers.

“…Deep tillage generally improves potato yield and grade (3,5,8,10,11,12,13), particularly when soil moisture is not adequate for Russet Burbank production. Tillage practices include preplant deep plowing, chiselling, and in-row subsoiling (precision subsoiling).…”

Soil compaction and erosion are problems in many Pacific Northwestern potato fields. We wanted to determine if zone-subsoiling would reduce these problems and improve potato yields and or grade without adversely impacting other production practices. Studies were conducted in Southern Idaho at six locations over two years on different soils and with different irrigation methods to assess the effects of zone-subsoiling immediately after planting on tuber yield and grade. Reservoir-tillage comparisons were made at three locations where sprinkler water application rates were higher than soil infiltration rates. Russet Burbank was represented by eight location-years and Russet Norkotah by two. Zone-subsoiling consistently improved tuber grade or increased tuber size. The biggest improvement was under furrow irrigation. Zone-subsoiling also tended to increase total yield in eight of ten location-years. Reservoir-tillage improved yield and grade, but zone-subsoiling did not without reservoir-tillage when water application rates were high. At no location did zone-subsoiling significantly decrease tuber grade or yield. Zone-subsoiling had no appreciable effects on hill configuration or seed-piece dislocation. Surface cracking and "water piping" occurred under furrow irrigation but were not significant problems. Results were similar for both cultivars. Additional studies will be needed to successfully incorporate zone-subsoiling into commercial production practices. CompendioLa compactaciOn y erosion del suelo son problemas presentee en muchos de los campos de papa del noroeste del Pacifico. Se queria determinar si una aradura profunda zonal podria reducir estos problemas y mejorar los rendimientos de papa y/o su grado sin impactar negativamente sobre otras practicas culturales de producciOn. Se condujeron estudios al Sur de Idaho, en seis localidades, durante dos aiios, con diferentes suelos y metodos de irrigaciOn, para determinar los efectos, de una aradura ' profunda zonal efectuada inmediatamente despues de la siembra, sobre el rendimiento en tuberculos y su grado. Se efectuaron comparaciones de acumulaciOn-aradura en tres localidades donde las tasas de aplicaciOn de agua por aspersion eran mas altas que las tasas de infiltraciOn en el suelo. Russet Burbank fue considerada durante ocho localidades-ailos y Russet Norkotah en dos. La aradura profunda zonal mejor6 consistentemente el grado de los tuberculos o incrementO el tamafio de los mismos. La mejora mas notable se efectu6 bajo irrigaciOn por surcos. La aradura profunda zonal tambien tuvo la tendencia a incrementar el rendimiento total, en ocho de las diez localidades-afios.

“…M ANY sons used for irrigated crop production contain indigenous or tillage-induced compacted layers. Potato is particularly sensitive to soil compaction (Bishop and Grimes, 1978;Dickson et al, 1992;Ross, 1986;von Loon and Bouma, 1978). McDole (1975) observed that a plow pan restricted potato root growth to the plow layer in silt loam and coarser textured soils.…”

Deep tillage of compacted soils can improve potato (Solanum tuberosum L.) tuber yield and quality if no other production factors are limiting. We hypothesized that within-row subsoiling and N placement would affect tuber yields and availability of plant nutrients. Potato (cv. Russet Burbank) was grown after winter wheat (Triticum aestivum L.) in 1989 and after dry bean (Phaseolus vulgaris L.) in 1990 on a furrow irrigated Portneuf silt loam (coarse-silty, mixed, mesic Durixerollic Calciorthid). Fall tillage treatments (disking, chiseling, and moldboard plowing) were split with zone subsoiling after planting. Nitrogen was broadcast before planting or banded beside the seed piece at planting across all tillage combinations. We estimated plant nutrient status and uptake each year with whole-plant and petiole samplings during tuber growth. Final tuber yield and quality were determined in early October. Fall tillage did not influence nutrient concentration and uptake, tuber yield, or quality. Zone subsoiling increased average plant dry weights 9%, total tuber yields 10% (4 Mg ha '), and quality, and increased P uptake an average of 11.6% (1.8 kg P ha -') without appreciably changing whole-plant or petiole P concentrations. Banding N increased average plant dry weight 6.4%, total tuber yield 9%, and N uptake 28% compared with broadcast N. Petiole NO 3-N, P, K, and Zn concentrations were higher where N was banded. There were no consistent zone subsoiling x N placement interactions. Higher nutrient applications may be required with zone subsoiling or to compensate for soil compaction problems.
