The Vegetable Report is one of several commodity-based agricultural research reports published by the University of Arizona.

This report was first published in 1965.

The purpose of the report is to provide an annual research update to farmers, researchers, and those in the agricultural industry. The research is conducted by University of Arizona and USDA-ARS scientists.

Both historical and current Vegetable Reports have been made available via the UA Campus Repository, as part of a collaboration between the College of Agriculture and Life Sciences and the University Libraries.

Other commodity-based agricultural research reports available in the UA Campus Repository include: Citrus Reports, Cotton Reports, Forage & Grain Reports, Sugarbeet Reports, and Turfgrass Reports.

  • An Examination of Whitefly Flight

    Byrne, D. N.; Oebker, Norman F.; Kingdon, Lorraine B. (College of Agriculture, University of Arizona (Tucson, AZ), 1987-05)
    A series of experiments are being conducted which examine how whiteflies accomplish flight. These are important because knowledge of how insects move may eventually lead to appropriate management strategies for migrating populations.
  • Downy Mildew of Broccoli - Promising New Fungicides for Disease Control

    Matheron, M. E.; Matejka, J. C.; Oebker, Norman F.; Kingdon, Lorraine B. (College of Agriculture, University of Arizona (Tucson, AZ), 1987-05)
    Downy mildew of broccoli, caused by the fungus Peronospora parasitica, is a perennial disease problem affecting winter broccoli production in Arizona. During 1985-87, potential systemic fungicides were evaluated in the field for disease control. In the 1985-86 season, a period of high disease incidence, lesion development was significantly reduced by fosetyl-Al (44 %), phosphorous acid (42 %), oxadixyl + mancozeb (35 %), chlorothalonil (33 %), metalaxyl + mancozeb (30 %) and metalaxyl + chlorothalonil (28 %). During the 1986 -87 growing season, disease incidence was low and lesion development was significantly reduced by phosphorous acid (82 %), fosetyl -Al or oxadixyl + chlorothalonil (77 %), metalaxyl + chlorothalonil (68 %) and chlorothalonil (54 %). Fosetyl-Al, phosphorous acid and oxadixyl were as effective as currently available fungicides ( metalaxyl and chlorothalonil) for control of downy mildew of broccoli in Arizona.
  • Sclerotinia Leaf Drop of Lettuce - Screening New Fungicides for Disease Control in 1986

    Matheron, M. E.; Matejka, J. C.; Oebker, Norman F.; Kingdon, Lorraine B. (College of Agriculture, University of Arizona (Tucson, AZ), 1987-05)
    In western Arizona, the incidence and severity of lettuce drop, caused by the fungus Sclerotinia sclerotiorum, can be significant during February, March and April. During 1986 a field trial was established to test new fungicides for disease control. Disease severity in the inoculated lettuce planting was significantly reduced by Baycor, Spotless and CGA-449, as well as the registered fungicides Ronilan and Rovral. Further testing of Baycor, Spotless and CQA-449 will be performed next year.
  • Onion Fertility Evaluation Under Different Levels of Salt Stress, Safford Agricultural Center 1986

    Clark, L. J.; Stroehlein, J. L.; Thatcher, L. M.; Oebker, Norman F.; Kingdon, Lorraine B. (College of Agriculture, University of Arizona (Tucson, AZ), 1987-05)
    Yield data were taken with a long -day onion variety, using different levels of nitrogen, phosphorous and potassium and at two different levels of soluble salts in the soil. Yields of the plots with additional fertilizer applied did not vary statistically from the check plot, which had 79 lbs/ac of nitrogen and 66 lbs/ac of P205. A correlation was found, however, between the electrical conductivity of a saturated paste extract from the soil and the yield of onions. A loss of 205 sacks (50 lbs /sack) of onions per acre are lost for each unit increase in soil conductivity.
  • Manganese Stresses and Mineral Nutrition of Cucumber Plants

    Crawford, T. W. Jr.; Stroehlein, J. L.; Kuehl, R. O.; Oebker, Norman F.; Kingdon, Lorraine B. (College of Agriculture, University of Arizona (Tucson, AZ), 1987-05)
    Cucumber plants in the vegetative phase of growth received deficient, sufficient, or toxic treatment of manganese (Mn) during a 15-day period beginning 43 days after germination. Deficiency and toxicity of manganese both supressed accumulation of fresh and dry weight. Stem length, number of leaves, and number of seconday meristems per plant were not significantly different among Mn treatments. Manganese-deficient plants accumulated less manganese and nitrogen but more copper and iron, and about the same amount of zinc, phosphorus, and potassium as the Mn-sufficient plants. Manganese toxicity caused cucumber plants to accumulate less copper, nitrogen, phosphorus, and potassium, but more manganese, and about the same amounts of iron and zinc as the Mn-sufficient plants.

  • Evaluation of Two Levels of Irrigation in Relation to Calsweet Watermelon Yield

    Livingston, M.; Ray, D. T.; Garrot, D. J. Jr.; Oebker, Norman F.; Kingdon, Lorraine B. (College of Agriculture, University of Arizona (Tucson, AZ), 1987-05)
    Calsweet watermelons were irrigated at two levels, utilizing a drip irrigation system for accurate rate measurements. Number and weight of harvested melons were recorded for four harvest dates. There were no significant differences in weight per melon, number of melons and total mean weight for the water treatments within the four harvest dates. For the entire season, number and total weight of melons were higher in the wet treatment; the weight per melon was higher in the dry treatment.
  • Effects of Soil Amendments on Crusting, Seedling Emergence and Yields of Onions, Tomatoes and Peppers

    Yacoub, M.; Clark, L. J.; Stroehlein, J. L.; Oebker, Norman F.; Kingdon, Lorraine B. (College of Agriculture, University of Arizona (Tucson, AZ), 1987-05)
    Studies were carried out at the Safford Agricultural Center using some soil amendments as anti-crusting agents. The results are promising in terms of improved stands on soils subject to crusting. Additional research is needed in order to determine proper rates which will reduce crusting without being toxic to the emerging seedlings.
  • Onion Variety Trial, Safford Agricultural Center 1986

    Clark, L. J.; Harper, F.; Thatcher, L. M.; Oebker, Norman F.; Kingdon, Lorraine B. (College of Agriculture, University of Arizona (Tucson, AZ), 1987-05)
    As a followup to the previous years onion variety trial (1), 23 of the more promising long-day varieties were retested along with 5 new intermediate-day varieties. The soluble salts and exchangeable sodium percentage were high (4340 and 28.1%, respectively) in the field where the onions were grown. This suppressed the yields significantly from the previous year. The top yielder produced 386 sacks (50 lbs) compared with 956 sacks in 1985. The top yielders from 1985, Durango and Inca, performed well again this year. The new intermediate-day varieties produced well also and seem quite promising.
