Author:
Henry C. Harris; John B. Brolmann
Source:
Agronomy journal 1966 v.58 no.6 pp. 575-578
ISSN:
0002-1962
Subject:
Arachis hypogaea; boron; calcium; calcium deficiency; flowering; fruit quality; fruit yield; leaves; nutrients; peanuts; roots; shoots; soil
Abstract:
... Comparisons of calcium and boron deficiency and normal peanuts (Arachis hypogaea L. var. “Florigiant”) were made from plants grown to maturity on soils supplying inadequate and adequate (with fertilization) levels of these nutrients. The characteristics of boron and calcium deficiencies were distinctive and strikingly different. Boron deficiency seemed to affect all parts of the plant. It changed ...

Subject:
Arachis hypogaea; calcium; cultivars; fruits; leaves; magnesium; markets; nutrient content; nutrients; peanuts; potassium; Virginia
Abstract:
... Six plant portions of each of three peanut (Arachis hypogea L.) cultivars representing the three market types were sampled on four dates. Many interactions occurred for each nutrient among the 'cultivars, plant portions, and sampling dates. The highest P(0.35%) and K(3.7%) contents in the cultivars were in the July 12 and October 10 leaf-samples, respectively, of the first lateral branches of ‘Vir ...

Abstract:
... Droughty conditions are implicated in causing low yields, poor grades and germination, and an increased incidence of aflatoxin in the peanut (Arachis hypogaea L.). However, very little is known as to when in the growth cycle drought is most critical. Effects of five drought treatments on peanut leaf diffusive resistance, yield, and quality characteristics were studied on rainfallprotected plots of ...

Abstract:
... Recently, Virginia farmers have experienced more cases of Mn deficiency in peanuts (Arachis hypogaea L.). More information was needed concerning the relative effectiveness of various commercial sources of Mn and methods of application on peanuts. Several sources of Mn were sprayed, broadcast, or banded on peanuts in 1975 and 1977 under conditions where considerable chlorosis typical of Mn deficien ...

Abstract:
... Cercospura sp. leafspot and defoliating arthropods are major pests which reduce the yield of peanuts (Arachis hypogaea L.) in the southeastern United States by decreasing the amount and effectiveness of photosynthetic surfaces. Nevertheless, in the past, yield reductions have been empirically predicted from season-end yields without considering the intermediate effects of leafspot or defoliation o ...

Abstract:
... Cytokinins are a major class of plant hormones that regulate plant growth and development. They promote cell division, drlay leaf senescence, and maintain protein and chlorophyll levels in detached leaves. Cytokinin activity is high during early stages of fruit and seed development. Thus, they offer a possible means to enhance reproduction of peanuts (Arachis hypogaea L.). Cytex³ is a water-solubl ...

Abstract:
... Yield improvement of peanut (Arachis hypogaea L.) is partially dependent on N nutrition. The differential ability of peanut cultivars to fix N symbolically and best utilize this N supply are traits that may be useful in plant breeding. Four peanut cultivars representing Spanish and Virginia subspecies var. vulgaris and var. hypogaea, respectively, were grown for 1 year on a sandy soil to determine ...

These appressoria developed rapidly on artificial membranes as well as on leaf surfaces. Fluorescein‐conjugated wheat germ agglutinin (WGA) bound strongly to the germ tube walls of U. fabae and its binding ability did not differ significantly in 3, 5 and 7 h old germ tubes. The binding o ...
