Of the analysis of the soil and clime conditions that are characteristic for the ash deposits as well as from the observations on the behavior of an enriched array of species, on these terrains there was observed the possibility of obtaining good results with the peanuts crop on the terrains covered by powerplant ash. There was chosen the Arachis hypogaea L. due to its capacity to capitalize the ash covered terrains, as well as by protecting by its vegetal mass a long time period of the vegetation period, decreasing the ash drift and the reduction of the environment pollution that is near the ash deposits. In supporting this species there was considered the thermic favorable regime of the zone, the high sunshine, the light texture, high water permeability of the deposited material, the plant density to the surface unit and the covering degree of the terrain by vegetal mass, that are favorable features in controlling the ash drift and environment pollution.

The most appropriate plant density and planting pattern to use for optimum growth and yield of groundnuts (Arachis hypogaea L.) in Eswatini among those currently used is not known, as the patterns are highly influenced by environmental conditions in specific regions. A field trial was conducted with the objective of determining the optimum plant density and planting pattern for groundnut in the Wet Middleveld of Eswatini. The experiment was conducted at the University of Eswatini, Luyengo Campus during the 2018/2019 cropping. The treatments consisted of three planting densities (i.e. 88,889 plants/ha, 44,444 plants/ha, and 29,630 plants/ha) and two planting patterns (i.e. Ridges and Raisedbeds) in a split plot arrangement. Results showed that all the measured parameters including seed yield were not significantly different in all treatments. However, the highest seed yield was obtained at low plant density which was 71.4 kg/ha followed by 568 kg/ha at medium and the least was 434 kg/ha at high plant density. The high plant density (88889 plants/ha) obtained the highest value of dry biomass (13018 kg/ha) at ridges which was higher than 3859 kg/ha obtained at the low plant density (29630 plants/ha) at raised beds at R6 growth stage. The ridges at the intermediate plant density (44444 plants per hectare) obtained the highest shelling percentage of 59.67% while the lowest (56%) shelling percentage was obtained at raised beds at 88889 plants per hectare. It is concluded that groundnuts at raised beds with low plant density yielded higher than those at ridges with high plant density. It is therefore, recommended that groundnuts be planted at raised beds with low plant density to increase groundnut production and for ease of harvesting.

ABSTRACT To commemorate the 50th anniversary of the American Peanut Research and Education Society (APRES) we examined the changes in average yields of peanut (Arachis hypogaea L.) during that time period. Before APRES, yields had never been greater than 2242 kg/ha (2,000 lb/ac). In 1967 the average yield was 1978 kg/ha (1967 lb/ac). In 2017 the average peanut yield was 4566 kg/ha (4074 lb/ac). Average yield gains for the first 50 years of APRES was 51.8 kg/ha/yr (46.2 lb/ac/yr). APRES played critical roles in facilitating research and extension to achieve these yield advances for the U.S. peanut industry.

SUMMARYAn investigation for 2 years at Kano and 1 year at Samaru evaluated the effects of plant density on vegetative growth, development and dry matter production and distribution of five varieties of groundnut. Growth and branching of individual plants were reduced at high populations but more dry matter was produced per unit area. Dense plants, particularly Spanish 205, developed a larger leaf area earlier in the season and were presumably able to make better use of light. Varieties F439.4 and 439.2 suffered the least reduction in the number of vegetative branches but the extra branches contributed few useful reproductive nodes.

ABSTRACT Standard row spacing for peanut (Arachis hypogaea L.) in Georgia is 91-cm in a single-row pattern. Narrower row spacings are often used in crops grown in rotation with peanut. Therefore, converting peanut to narrower row spacing may be easier and beneficial to some growers if cultivars and seeding rates can be identified that can be grown in narrow rows without a reduction in yield and grade. Based on current University of Georgia recommendations, peanut is typically planted at 19 seed/m with a 91-cm row spacing. Using narrower row spacing and constant seeding rates, increased seed costs would be observed. The objectives of this research were to evaluate the influence of cultivars and seeding rate in peanut planted in 76-cm single rows on yield, grade, and tomato spotted wilt virus (tospovirus) (TSWV) incidence. Experiments were conducted in 2008, 2010, and 2014 in Tifton, GA and in 2014 at Camilla, GA. Treatments were comprised of three cultivars (varying each year) and three seeding rates (14, 17, and 19 seed/m). Results indicate that pod yield, grade, and TSWV incidence were not affected by seeding rate. Seeding rate significantly influenced plant density where 14, 17, and 19 seed/m seeding rates resulted in 12.1, 13.2, and 13.8 peanut plants/m, respectively equating to a 9% and subsequent 4% increase in plant density as seeding rate increased. Seeding rate did not affect the rate of canopy closure, but cv. Georgia-12Y and TUFRunner™ ‘511’ had faster canopy closure than Georgia-06G. Peanut grade (total sound mature kernels) was not influenced by seeding rate, but did differ between cultivars. From these results, it can be concluded that 76-cm single-row can provide adequate yield and grade across multiple seeding rates. In addition, this study confirms that cultivar selection is the primary means for reducing TSWV incidence and altering grade in 76-cm peanut production.

Objetivo: Evaluar la germinación de cacahuate (Arachis hypogaea L.) mediante el uso de diferentes dosis de ácido giberélico (GA3). Diseño/metodología/aproximación: Se empleó un diseño completamente al azar. Se utilizaron tres tratamientos con 20 repeticiones. Tratamiento 1: 0.05gr/L de ácido giberélico (GA3), Tratamiento 2: 0.10gr/L de ácido giberélico (GA3), Tratamiento 3: 0.15gr/L de ácido giberélico (GA3) y Tratamiento 0: Testigo. Se utilizaron semillas de cacahuate de la variedad Virginia. Los parámetros a evaluar fueron, la altura de plántula, número de hojas, medida de raíz y biomasa.  Las medias fueron comparadas por la prueba de Tukey a un nivel del 5% de confianza. Resultados: Los tratamientos indicaron que el Tratamiento 0 (Testigo) obtuvo un porcentaje de germinación de 85%, siendo mayor que el tratamiento 3 (0.15gr/L de GA3) con un 75% de germinación, sin embargo, el tratamiento 1 (0.05gr/L de GA3) y 2 (0.10gr/L de GA3) presentaron una mejor respuesta al obtener un 95% de germinación cada uno. Limitaciones del estudio/implicaciones: El tratamiento 3 causa efectos negativos en la germinación de la planta. Hallazgos/conclusiones: Es necesario dar seguimiento a la investigación para un mejor control del ambiente y ampliar las dosis de GA3, así como aumentar la velocidad de germinación aplicando 0.15gr/L de GA3.
