“…For this reason, the pod number and pod weight per plant was increased when the plant population decreased. These results are in agreement with the findings of Sorensen et al (2005), Kurt (2007), Kadiroglu (2012), Konlan et al (2013) and Dapaah et al (2014) There was a statistically significant difference in pod number per plant among the plant densities in different planting pattern in both years. The pod number per plant values varied between 16.78-32.78 plant -1 in 2013 and between 15.71-30.53 plant -1 in 2014 (Table 3).…”

This study was conducted at the Cukurova University research farm as a main crop in 2013 and 2014 in Adana, Turkey. The objective of this study was to determine the effect of twin row planting pattern and plant densities on yield and yield components of peanut. The experimental design was a Randomized Complete Block Design with three replications. The Halisbey (Virginia type) variety was used as a plant material in this research. The planting pattern was used as twin-row and conventional single-row. The row spacing was 70 x 25 x 70 cm, 75 x 25 x 75 cm and 80 x 25 x 80 cm for twin-row planting pattern and 70 cm for single-row pattern. Intra-row spacing of 10, 15 and 20 cm was arranged for different plants population. According to a two-year average, the highest pods yield (7833.6 kg ha-1) was obtained from 70 x 25 x 70 x 10 cm (21.05 plants m-1) twin-row planting pattern while the yield was 6688.8 kg ha-1 in single-row planting pattern as 70 x 15 cm (9.43 plants m-1). The yield increase was 17.86% in 70x25x70x10, 16.70% in 75x25x75x10 and 15.79% in 80x25x80x10 twin-row pattern, compared with traditional single-row planting pattern.

“…Hundred-seed weight showed significant and positive correlations with important yield attributing traits in the present study (Table 2). Similarly, the results indicated positive correlation with number of pods per plant (Nath and Alam 2002;Dapaah et al 2014), and flowering time (Upadhyaya 2003) in different studies. Such common relationships obtained from above studies suggest that consideration of reduced number of traits in characterization using easily measurable traits in groundnut may be more rewarding.…”

“…The genotypes with higher number of pods per plant could be used as a useful genetic resource for obtaining higher yield potential. Shelling percentage which shows an index of percentage of grains or seeds (Dapaah et al 2014) is one of the important selection criteria in groundnut breeding (Anothai et al 2008). However, Minimol (2001) reported shelling percentage is highly influenced by genotypic×environment interactions.…”

The genetic assessment of 90 germplasm lines and six varieties of groundnut (Arachis hypogaea L.) were done with 13 morphological traits and 125 Simple Sequence Repeats markers. Out of 125 molecular markers, 26 were polymorphic and produced 105 alleles. The genetic diversity was found to be 52-83 per cent and Polymorphic Information Content (PIC) was 0.46-0.81 with a mean of 0.42 indicating higher magnitude of genetic diversity in the test genotypes. Analysis of molecular variance showed variation among and within individuals based on allelic variation. Principal Co-ordinate Analysis based on origin of the genotypes formed three major population groups and the genetic analysis determined by population structure divided all the germplasm lines in to 10 populations. Significant and positive correlation was observed between hundred kernel weight and hundred pod weight (r=0.769) and kernel yield (r=0.899); sound mature kernel and pod weight with kernel yield, weight of kernels and harvest index. Genotypes from distinct clusters may be selected in hybridization programme for groundnut improvement. The information on clustering of genotypes will be helpful in identification of novel and superior germplasm for hybridization and development of improved varieties.

“…Plant density and planting pattern are efficient management tools for maximizing crop yield by optimizing resources utilization such as light, nutrients and water and reduce soil surface evaporation [9,10]. The response of groundnut to plant density and planting pattern has been investigated in many areas of the world; however, such information is scanty and not wellstudied in Eswatini.…”

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.
