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.

A field experiment was conducted at the experimental field, Dept. of Field Crop , Coll. of Agric. Univ. of Baghdad during the yeans of 2010 and 2011 to study growth and yield of peanut as affected by planting methods and plant population. A factorial arrangement in RCBD design with four replications were used , with two factors, the first one: three planting methods (planting on East, West and Twin rows) and the second factor: four spacing between plants (15, 25, 35 and 45) cm. The results showed that the planting method on east produced highest dry weight (117.51, 100.64) g.plant-1, growth rate (625.10, 532.40) mg.plant-1.day-1 , seed yield per plant (25.16, 32.25)g.plant-1, protein percent (26.01, 26.20)% for both seasons respectively. Moreover planting method on twin row  gave highest pod yield (4180, 3842) kg. ha-1, oil percentage (46.00, 46.20)% for both seasons respectively. The highest plant density 15 cm between plants gave highest pods yield (3960 3031 kg.ha-1, seed yield (2328.7, 1761.0) kg. ha-1, oil percentage (46.50, 46.28)%  for both seasons, respectively. The lowest plant density 45 cm between plants gave highest dry weight (124.07, 114.07) g.plant-1, growth rate (659.90, 603.50) mg. plant-1.day-1, seed yield per plant (36.05, 31.07)g. plant-1, protein percentage (26.40, 26.20)% for both seasons, respectively. The planting method on twin row with the high plant density 15 cm gave highest seed yield (2894.1, 2542.0) kg.ha-1, while the planting method on west and the low plant density 45 cm gave the lowest seeds yield (1051.3, 912.0) kg.ha-1 for both seasons, respectively.

Plot Design

A field experiment was conducted in the Experimental Research Farm of School of Agricultural Sciences and Rural Development (SASRD), Nagaland University during the kharif season 2018. Groundnut variety ICGS-76 was sown @ 70 kg ha-1 for 60×20 cm2 spacing. The experiment was laid in split plot design with three replications. The main plot treatments consisted of two lime levels: lime @ 0 t ha-1 and lime @ 3 t ha-1 while the sub- plot treatments consisted of five sulphur levels: sulphur @ (0 kg ha-1, 10 kg ha-1, 20 kg ha-1, 30 kg ha-1 and 40 kg ha-1 along with recommended dose of fertilizer at 20:60:40 kg N, P2O5 and K2O ha-1 respectively in the form of diammonium phosphate and murate of potash. The results showed that application of lime @ 3 t ha-1 gave higher growth and yield attributes compared to no lime and also application of sulphur @ 40 kg ha-1 gave higher growth and yield attributes compared to lower doses of sulphur though there was only slight increase in the attributes between each successive doses of sulphur. Overall application of lime and sulphur increased all the yield attributes of groundnut, where the highest number of pods plant-1, seeds pod-1, 100 kernels weight, pod yield, kernel yield and stover yield were recorded when treatment was done with lime @ 3 t ha1 and sulphur @ 40 kg ha-1.

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.
