Yield Responses

This study examined the influence of irrigation, soil nitrogen (N) levels and seed piece spacing on the yields and tuber size distribution of Norland, Russet Burbank and Shepody potatoes over three seasons at two sites in central Saskatchewan. The crops were grown under standard irrigated conditions or on dryland with in-row spacings of 15, 23 or 30 cm and total N levels of 200 or 300 kg ha−1 as either preplant or split applications. Irrigation greatly enhanced yields of all tuber size categories in the drier years but had less effect if seasonal precipitation reached or exceeded normal levels. Smaller size tubers formed a greater proportion of the total yield in crops exposed to drought stress. Norland was less affected by drought than the later-maturing cultivars. Yield responses to N were limited to situations where soil moisture was abundant or crop demand for nutrients was increased by close in-row spacings. Close in-row spacing increased total yields in some cases, while in others it resulted in a reduction in tuber size with little effect on overall yields. Yields for the cultivar Norland were less affected by seed piece spacing than yields for Russet Burbank or Shepody. Key words: Solanum tuberosum, drop seed, spacing, fertility

Net Returns

Seed-piece spacing is an important economic consideration in the production of potatoes and optimum varies by cultivar and intended market. A study was designed to determine the influence of seed-piece spacing on yield, tuber size distribution, net returns and stem and tuber density of three processing potato cultivars. Seed tubers of cvs. Russet Burbank, Frontier Russet and Ranger Russet were planted 8, 15, 23, 31, 46, 61, 76, or 91 cm apart at two locations in 1988 and 1989. Total, marketable (U.S. No. 1), and mid-size (226–452 g tubers) yield, yield of five incremental size categories, net profits from a typical processing contract, and stem and tuber density (number per m of row) were determined. All three cultivars achieved highest total yields at the narrowest (8 cm) spacing. Marketable and mid-size yield were optimized between 15 and 31 cm depending on the cultivar. The size distribution of tubers shifted from a predominance of small tubers at the narrow spacing treatments to a predominance of large tubers at the wide spacing treatments. The rate of shift across spacing treatments was cultivar dependent. Russet Burbank showed a bimodal response to spacing for net returns with optimums at the 23- and 46-cm spacing treatments. Frontier Russet and Ranger Russet showed optimums at 23 cm. All three cultivars gave maximum mid-size yields at a stem density of 10.5–12.1 per m of row and a tuber density of 23.9–24.9 per m of row.

Optimum Spacing

Seed piece spacing is an important economic consideration in the production of potatoes (Solanum tuberosum L.). The optimum spacing varies with cultivar and intended market. A study was designed to determine the influence of seed piece spacing on yield, tuber size distribution, net returns, and stem and tuber density of three processing potato cultivars. Seed tubers of cultivars Russet Burbank, Frontier Russet, and Ranger Russet were planted 8, 15, 23, 31, 46, 61, 76, or 91 cm apart at two locations in 1988 and 1989. Total, marketable (U.S. No. 1), and midsize (226–452 g tubers) yield, tuber size distribution, net profits from a representative processing contract, and stem and tuber density (number per meters of row) were determined. All three cultivars achieved highest total yields at the narrowest (8 cm) spacing. Maximum marketable and midsize (226–452 g) yield occurred between 15 and 31 cm, depending on the cultivar. Size distribution shifted from a predominance of small tubers at narrow spacings to a predominance of large tubers at wide spacings, and the rate of shift was cultivar-dependent. `Russet Burbank' showed a broad range of optimal spacing for net returns, with a maximum in the range of 23 to 46 cm. Optima for `Frontier Russet' and `Ranger Russet' were between 15 and 46 cm. Of the four tuber measurements, midsize yield appeared to be best for determining optimum spacing. Marketable yield was also a useful measurement. All three cultivars gave maximum midsize yields at a stem density of 10.5 to 12.1 per meter of row and a tuber density of 23.9 to 24.9 per meter of row. Tuber density showed some promise as a predictor of optimum seed piece spacing for new cultivars.

Methyl Decanoate

SummaryApplication of methyl decanoate to a potato crop about the time of tuber initiation reduced the total yield and the yield of tubers in the grade 2·5–5·5 cm though neither of these reductions were significant. However, application of 2,3,5-triiodobenzoic acid increased the yield of tubers 2·5–5·5 cm by up to 20% while having no significant effect on total tuber yield. This change in the tuber size distribution was due to a more even partition of photosynthate between tubers and not to an increase in the total number of tubers.

The Relationship

Agronomic crops with resistance to the herbicides dicamba and 2,4-D are currently in the regulatory approval process. The potential increased use of these herbicides has raised concern among vegetable producers about potential off-target movement and implications to crop yield. The overall goal of this research was to describe the relationship between visually estimated crop injury and snap bean and potato yield and quality. In snap bean in 2011, injury from dicamba 7 d after treatment (DAT) ranged from 19% at the 1.2 g ae ha−1application rate to 45% at the 7.0 g ae ha−1application rate. By 28 DAT in 2011, injury from 2,4-D was similar to the nontreated control. However, early-season injury in 2011 delayed snap bean flowering and reduced crop yield compared to the nontreated control for all treatments except where the 1.4 g ae ha−1rate of 2,4-D and glyphosate at 7.0 g ae ha−1were applied. Snap bean injury from dicamba was greater than that from 2,4-D at all rating timings in 2011 and two of three rating timings in 2012, and crop yield was reduced compared to where 2,4-D was applied and the nontreated control in both years. Potato tuber size distribution was variable and total yield did not differ among treatments and the nontreated control in 2011. In 2012, tuber size distribution was again variable, but more nonmarketable cull potatoes were harvested when dicamba was applied to 25-cm potato plants at the 7.0 g ae ha−1rate compared to any other treatment. Snap bean injury observations about 3 wk prior to harvest were strongly correlated with crop yield (r= −0.84 and −0.88 in 2011 and 2012, respectively), allowing time to make informed harvest decisions relative to crop quality. In contrast, the relationship between potato injury and tuber yield was poor and highly variable in both years.

Drought Effects

Abstract Drought sensitivity of potato leads to a reduction in total tuber yield and marketable yield. An investigation of drought effects on tuber yield attributes will facilitate our understanding of how to reduce such huge yield losses. We have evaluated tuber yield, tuber size distribution and marketable yield of a set of 103 European commercial potato cultivars under irrigated and non-irrigated conditions in the field. The multi-year results from two locations, Connantre, France (2013–2015) and Nieuw-Namen in Zeeland, The Netherlands (2013–2014), were analysed. We used Normal and Gamma Distribution models to describe the tuber size distribution of tuber fresh weight and tuber number, respectively. The interactions among parameters of tuber size distribution and total/marketable tuber yield traits were analysed using correlation matrices and biplots. Finally, we used a 14K Infinium SNP marker array to find associations between the parameters or traits and genetic loci on the potato genome. Late foliage maturity facilitated a wider spread of tuber size distribution in favour of larger-sized tubers. Drought effects on total yield were representative of their impact on marketable yield, however, absolute values of total tuber number may not be indicative of marketable number of tubers. We found significant marker-trait associations between a region on chromosome 3 and the spread of tuber number distribution, size class with maximum tuber number and marketable fractions of tuber number and tuber weight. These findings will contribute to improvement and selection for drought tolerance in potato.
