Field experiments were carried out at different locations in Prince Edward Island each year for 3 consecutive years to determine the effects of calcific limestone, dolomitic limestone, and gypsum on yields and nutrition of two cultivars of Brussels sprouts (Brassica oleracea var. gemmifera). The soils at the sites selected had initial pH levels of 4.9–5.7. Preplant, broadcast applications of gypsum at 5.5 t ha−1 resulted in yield increases of about 30% at all locations. Analysis of leaf tissue collected when the sprouts began to form indicated that Ca, Mg, Mn and Zn concentrations of approximately 1.4–2.6%, 0.25–0.32%, 88–274 μg g−1 and 26–35 μg g−1, respectively, are within the sufficiency range. The incidence of internal browning was not affected by either the lime or gypsum treatments at the two locations where this disorder occurred.

The effects of preplant soil applications of B, Mo and dolomitic limestone on yields and leaf tissue nutrient concentrations of Rally peas were investigated at five locations with initial soil pH levels of 5.1–5.9. Experiments were conducted for two consecutive growing seasons at each location. All treatments were preplant incorporated in a 2 × 2 × 2 factorial design with five replicates. Yields of shelled peas, adjusted to tenderometer 100, varied between experiments from 1.1 to 4.8 × 103 kg ha−1 and were not generally affected by B, Mo or lime at application rates of 2.0, 0.25 and 10 000 kg ha−1, respectively. Also, the micronutrient and lime treatments had no significant effects on germination, vine length, pea/vine ratio or maturity. Leaf tissue B, Mo and Mg concentrations were increased by the applications of B, Mo and dolomitic limestone, respectively. However, leaf tissue Ca concentration was not affected by the lime treatment. The results indicate that leaf tissue concentrations of 16–74 μg g−1 B, 0.04–1.34 μg g−1 Mo and 0.23–0.55% Mg were within the sufficiency range.Key words: Peas, boron, molybdenum, dolomitic limestone, yield, leaf tissue concentration

Field experiments were conducted at four locations in Prince Edward Island to determine the effect of applied B on leaf tissue B and yields of beans (Phaseolus vulgaris L.) and cabbage (Brassica oleracea var. capitata L.) in the year of application of B and again the following year. Application rates of 8.8 kg B∙ha−1 reduced bean seed yields at all locations and the 4.4-kg B∙ha−1 rate reduced yields at two locations in the first year. Leaf tissue B levels > 109 μg∙g−1 are clearly toxic for beans and seriously reduced bean yields. Furthermore, the yield and visual symptom data strongly suggest that tissue B levels even as low as 60 μg∙g−1 are toxic for this crop. No significant reductions in bean yields were noted in the second year crop, even at the 8.8 kg B∙ha−1 rate. Rates of up to 8.8 kg B∙ha−1 did not cause any reduction in cabbage yield even during the year of application. Leaf tissue B concentrations as high as 71–132 μg∙g−1 were not related to any B toxicity in cabbge. Added B did not increase yield of either beans or cabbage. Even though leaf tissue B levels as low as 16 μg∙g−1 in cabbage and 26 μg∙g−1 in beans occurred, no B deficiency was found. After the first and second years of beans the hot-water-soluble B in the soil ranged from 1.4 to 1.9 and from 0.8 to 1.2 μg∙g−1, respectively, where B had been applied at 8.8 kg∙ha−1.

Brussels sprouts (Brassica oleracea var. gemmifera DC., Jade Cross) require no potassium fertilizer on Prince Edward Island soils if exchangeable soil K as determined by neutral 1 N ammonium acetate exceeds 100 ppm. Below 75 ppm exchangeable soil K, 186 kg K/ha must be applied for maximum yields. Potassium treatments increased yields at only three of 12 locations studied. Leaf tissue potassium concentration was significantly increased at all locations by the fertilizer treatments. Neutral 1 N ammonium acetate for determining exchangeable K was the best soil analysis extract among those tested for measuring available potassium. Tissue analysis gave no information beyond soil analysis for predicting potassium fertilizer requirements on any soil studied.

Field experiments were carried out in Prince Edward Island to investigate the effect of broadcast and foliar B applications on brown-heart, leaf nutrient content, yield and storage of two rutabaga cultivars (Brassica napabrassica Mill.) at one site in 1994, 1996 and 1997. The two cultivars, York and Thomson Laurentian, were seeded with preplant broadcast B at 0, 2.24, 4.48 and 6.72 kg ha-1. Within each preplant broadcast B treatment, foliar B was applied as Solubor (20.5% B) at 0 and 2.24 kg B ha-1. Foliar B was applied 28 and 42 d after seeding at 1.12 kg B ha-1 at each application. Averaged over these 3 yr, total yield was reduced by broadcast B and foliar B applications. Applications of B increased soil and tissue B levels. Boron was within acceptable levels for plant tissue and soil in all years; however, brown-heart was severe in 1994. On average, the incidence of brown-heart was lower in York than in Thomson Laurentian, and further decreased with increasing rate of B, both broadcast and foliar.

Research on sapodilla (Manilkara zapota) has been very limited. A field study was conducted to determine the yield potential, fruit quality traits, leaf nutrient composition, and scion/rootstock compatibility of ‘Prolific’ sapodilla grafted onto 16 sapodilla rootstock seedlings. For this purpose, seedlings (maternal half-sibs) of cultivars Adelaide, Arcilago, Aruz, Blackwood, Blocksberg, Guilbe, Hanna, Jamaica-1, Larsen, Mendigo-1, Gallera, Morning Star, Russel, Prolific, Timothe, and Vasallo-1 were used as rootstock seedlings and evaluated during 7 years of production at Isabela, PR. Year showed a significant effect on the number of fruit per hectare, yield, individual fruit weight, fruit length and diameter, and total soluble solids. Rootstock seedlings had a significant effect on the number of fruit per hectare, yield, and individual fruit weight but had no effect on other fruit traits. The year × rootstock interaction was not significant for any of the variables measured in the study. Rootstock seedlings ‘Timothe’, ‘Vasallo-1’, ‘Larsen’, and ‘Aruz’ had the highest 7-year mean for number and the yield of fruit averaging 4479 fruit/ha and 1245 kg·ha−1, respectively. ‘Timothe’ and ‘Vasallo-1’ significantly out yielded the ‘Prolific’ rootstock seedling. The number of fruit per hectare and corresponding yield obtained in this study were very low probably as the result of wind exposure, the presence of the fungus Pestalotia causing floral necrosis, or both. Scion/rootstock incompatibility was not the cause of the low yield performance of grafted trees. The average individual weight of fruit was 282 g and ranged from 264 to 303 g. Averaged over rootstock seedlings, leaf tissue nutrient concentration did not vary greatly over time. Moreover, tissue nutrient concentration was similar before and after fertilization events.

More than 3000 acres of commercial muscadine (Vitis rotundifolia) vineyards exist in the southeastern United States. The muscadine wine industry is generating an economic impact of $1 billion in North Carolina alone. Muscadines have been cultivated since the 1800s, but muscadine vineyard fertilizer programs, tissue sampling, and nutrient sufficiency ranges continue to be based on anecdotal knowledge. While seasonal changes in tissue nutrient concentration are well documented in bunch grape (Vitis vinifera), questions remain about the seasonal and cultivar-dependent dynamics of muscadine leaf tissue nutrient concentrations. The aim of this study was to assess temporal and cultivar-related differences in tissue nutrient concentration of mature commercially grown muscadines. Leaf tissue nutrient concentration of the muscadine cultivars Carlos and Noble were assessed in three vineyards (Piedmont North Carolina, north Georgia, and south Georgia) at bloom, véraison, and postharvest in 2018 and 2019. Our results show that nitrogen (N), phosphorus (P), and manganese (Mn) were generally above the recommended sufficiency ranges, with calcium increasing over the season—and N, P, and potassium decreasing over the season. ‘Carlos’ had significantly higher levels of N and P, compared with ‘Noble’, while ‘Noble’ showed higher Mn concentration than ‘Carlos’. With this evaluation, we demonstrate the need for a modification in muscadine tissue nutrient sufficiency ranges that are based on cultivar and vine growth stage.

The effects of various rates of nitrogen, phosphorus, and potassium on the boron concentration of leaf tissue of cauliflower (Brassica oleracea var. botrytis L. ’Snowball Y’), Brussels sprouts (Brassica oleracea var. gemmifera Zenker ’Jade Cross’) and peas (Pisum sativum L. ’Dark Skin Perfection’) were investigated at several locations in Prince Edward Island. Except for N on cauliflower, B concentrations of leaf tissues of these crops were not greatly affected by the N, P, or K treatments. Applied N increased the B concentration of cauliflower leaf tissue at eight of the nine locations investigated.

Field experiments were carried out at two different locations in Prince Edward Island each year for 3 consecutive years to determine the effects of added nitrogen and potassium on yields of rutabagas (Brassica napobrassica Mill.) and subsequent losses during a 6-mo period in two storage regimes. Preseeding applications of nitrogen at 120 kg ha−1 compared to 40 kg ha−1 increased marketable yields by 7–18%. Applications of potassium at 180 kg ha−1 compared to 60 kg ha−1 had no effect on marketable yields. Mean weight losses from dehydration of rutabagas held for 6 mo at about 2 °C and 95% RH and at about 5 °C and 90% RH were 5.2% and 10.8%, respectively, and were not affected by the nitrogen and potassium treatments. Also, the nitrogen and potassium treatments had no effect on the proportion of the rutabagas that remained in marketable condition during the storage period. Analysis of leaf tissue collected when the rutabaga roots began to enlarge indicated that nitrogen and potassium concentrations of approximately 5.0–6.0% and 2.1–5.9%, respectively, are within the sufficiency range.Key words: Rutabaga, Brassica napobrassica, yield, storability, nitrogen, potassium

Boron application rates as high as 8 and 16 kg ha−1 were not toxic to Brussels sprouts (Brassica oleracea L. ssp. gemmifera). These rates resulted in leaf tissue B levels of 123 and 161 μg g−1 and of 7.6 and 9.1 μg HWS B g−1 soil, respectively. Rates of 8–16 kg B ha−1 would, however, be seriously toxic to many crops. It is therefore strongly recommended that rates of B applied to Brussels sprouts should not exceed 2 kg ha−1. Such B applications should eliminate B deficiency in most crops and would not pose a threat of B toxicity to crops grown in the following year.

Both studies and information are lacking concerning Ca and S nutrition of rutabagas (Brassica napobrassica Mill). Five field studies were conducted to determine yield response of rutabagas to soil-applied gypsum (CaSO4·2H2O), lime (calcite) and elemental S on sandy loam to loamy sand Orthic Podzols in Prince Edward Island. Marketable yield of rutabagas was not affected by addition of Ca or S amendments. Gypsum increased the S content of rutabaga leaf tissue and reduced soil pH. In this study, a soil extractable Ca level of at least 318 µg g-1 soil appears adequate to support rutabaga growth. Key words: Rutabagas, calcium, gypsum, calcite, elemental sulphur
