“…This means that the possibility of K increases from NaCI applications has not been fully considered in most discussion of the role of N a in nutrition of slightly respDnsive plants. In the present investigation, yield evidence appears to be in ai!reement with the conclusions of workers such as Harmer et al (1953) and Gammon (1953) that white clover and some pasture grasses fall in the group of plants which show slight to medium responses to Na with insufficient K, and that Na can partially substitute for K nutrient in some pasture species under conditions of moderate K deficiency, but cannDt substitute as effectively, if at all, when the deficiency is acute (e.g., Hemingway 1961).…”

ABSTRAGT Over a period of four years, sodium and potassium chloride at 1 and 2 cwt/ac/annum, and mixtures in various proportions, were compared on a grass-clover pasture in a field trial on Horotiu sandy loam, using the technique of mowing with return of clippings.Responses to NaGI were much smaller than those from th~ same rates of KG!. Yield increases of mixed herbage from 1 and 2 cwt NaGI averaged 13 p~r cent and 18 per cent respectively in the first two years, but fell below 10 per cent and were no longer significant in the third and fourth years. In the presence of sub-optimal amounts of KGl, however. 1 cwt NaGI continued to give responses throughout the trial period. Responses to 1 and 2 cwt KGl averaged 32 per cent and 49 per cent respectively over th~ four years.Two cwt NaGI increased the percentage of white clover (Trifolium repens L.) by 25 p~r cent and the per acre yield by 41 per cent, but 2 cwt KGl increased these values by 166 per cent and 295 per cent respectively. Ryegrass (mostly Lolium perenne L.) p~rcentages were little affected, but 2 cwt NaGI increased ryegrass yields by 25 per cent, and 2 cwt KGI by 78 per cent. All treatments reduced the percentage of other grasses, but had little ~ffect on their yields. Sodium chloride increased plant K levels in all samples taken in 1954 and 1955 when K deficiency was slight to moderate. In 1957-8, however, when K deficiency in the plots without K was a~ute, such increases were found only in th~ moderately deficient plots which received sub-optimal amounts of KG!.Soil analyses failed to demonstrate release of non-exchangeable K from the soil by NaGI in the absence of plants.The NaGI responses appear to be best explain~d as due mainly to increased K uptake or displac~ment of K from the roots to the foliage.

“…Harmer et ai. (92) classified crop species into four categories on the basis of their response to N a+. These include (a) species that fail to show growth responses and those that respond slightly to Na+ when the K+ supply is insufficient, (b) species that exhibit a slight to medium growth response to Na+ when the K+ supply is inadequate, (c) species that exhibit a slight to medium growth response to Na+ when the K+ supply is ample, and (d) spe cies that exhibit a large growth increase from N a+ addition when the K+ supply is adequate.…”

“…When plants are high in K, Na responses have been observed (12,18,31) but most often these are much reduced or not at all in evidence (4,17,18,22,35). Direct effects of Na on sugar beet growth in field experiments have been reported for muck soils by Harmer and Benne (9) and Harmer et al (10), for sand cultures by Tullin (32), and for table beets in pot experiments with soils by Larson and Pierre (18). Sodium deficiency symptoms have been reported (32) or described (9) in only a few instances and so far no specific function of Na, not performed by K, has been recorded (17,19).…”

Chlorine, sodium and silicon have long been considered as elements that are possibly essential to the growth and development of sugar beets and other plants. Of these elements Cl has been found just recently by Broyer et al (2) to correct a severe nutritional deficiency of the tomato plant when grown in low halide culture solutions. Raleigh (28) Much has been written about Na in terms of direct and indirect effects upon plant growth (5,9,10,19,20,23 In view of these reports, often indefinite in their conclusions, it was thought worthwhile to re-examine Na, Si and Cl in relation to the growth of sugar beet plants by adding these elements to otherwise complete culture solutions prepared from "chemically pure" salts. The initial experiment was of a factorial design using two levels of the elements in question. The first level of Cl, Na or Si was the amount present as an impurity in the salts and distilled water. The other level was an exact quantity added. It was thought that if the requirement for any one or more of these elements was larger than that provided by the impurities present, it would be revealed by the increased growth of the plants at the higher nutrient level. If increased growth was not obtained, the second step to be taken would include a further purification of all salts for each of the elements not found to enhance growth or development of the sugar beet plant. Two other factors were also included in the experiment; K at 2 levels and 2 beet varieties, giving a total of 5 factors each at 2 levels. METHODS AND MATERIALSPLANT CULTURE: The sugar beet (Beta vulgaris) varieties used in the 25 factorial experiment were U.S. 22/3 and GW 304, and for the chloride series experiment, U.S. 75
