“…This is consistent with the gemieral PLANT PHYSIOLOGY view that the mineral requirements of the fruit are satisfied at the expense of the vegetative tissue if the external supply falls short of supplying the needs of both. However, it has been demonstrated by HAMNER (9), LOEH-WING (12), and WADLEIGH (22) that the lack of balance may accentuate a given deficiency or be more detrimental to growth than generally realized.…”

“…HOAGLAND (6) discussed the effect of potassium on decreasing the absorption of calcium and magnesium. LOEHWING (7) found that the addition of potassium chloride to a number of soils depressed the percentages of calcium and magnesium in dent corn, wheat, and oats. SIDERIS and YOUNG (12), WALSH and 0 'DONOHOE (13), PHILLIS and MASON (9), and others, have presented data on the depressing effect of potassium on the percentages of calcium and magnesium in plants.…”

The present study was undertaken to determine the genieral nutrient requirements of the sweetpotato since field fertilizer tests have yielded a variety of responses with different fertilizer treatments. Sweetpotatoes usually respond to small applications of nitrogen fertilizers but excessive fertility often results in too much vine growth and few storage roots.The study to be reported was conducted on the influence of three or more concentrations of the following chemicals upon vine growth, storage root production, and chemical composition of the sweetpotato plant: NaNo,, NaH2PO4, CaCl2, MgSO4, KCl, KCl plus NaCl, K2SO4 and H,BO,.Data are presented in the present paper on the relationships between mineral nutrition and (1) storage root and vine weight; (2) general appearance of the leaf blades, storage roots, and fibrous roots; (3) mineral composition of the leaf blades, petioles, stems, storage roots and vines; and (4) carbohydrate composition of the leaf blades. MethodsTwo-gallon, ulazed crocks were filled with Ottawa silica sand. The opening for drainage near the base of the crocks was filled loosely with glass wool to prevent escape of the sand. The crocks were placed out-of-doors on two benches raised about 3 feet above the ground, in 32 groups of 12 each. The benches were located in the open away from the shading effects of trees and buildings. Glazed, 50-liter crocks were placed in front of each group of 12 two-gallon crocks, and used as reservoirs for holding nutrient solutions. The 50-liter crocks containing nutrient solutions were covered to exclude sunlight and rain.Uniform Triumph sweetpotato sprouts were planted one to a crock on May 9, 1945. The nutrient solutions were added as frequently as seemed necessary to supply moisture and nutrients. The

“…In an earlier investigation of certain grain plants grown on humus soils, foliar chlorosis was frequently observed following use of lime to correct soil acidity (31). Tissue fluids of plants from alkalinated humus soils were found to be uniformly low in free acidity, and iron chlorosis was observed in plants in the low acid ranges.…”

“…Investigation of expressed sap has not, however, proven entirely fruitless because the degree of acidity has been found to be measurably corr'elated with illumination (9,12,14,23,46,51,53), the photoperiod (13), temperature (3,26), age (3,4), season (1,22), the axial gradient (11,28), and nutrient conditions (6,7,10,31,36). Discovery of such correlations is often the initial step in the determination of their underlying physiological mechanisms.…”
