Response of Two Groundnut (Arachis hypogaea L.) Varieties to Sowing Date and NPK Fertilizer Rate in a Semi-Arid Environment: Yield and Yield Attributes

Participatory variety selection of groundnut (Arachis hypogaea L.) in Taricha Zuriya district of Dawuro Zone, southern Ethiopia

“…The highest seed yield (1805.84 kg ha −1 ) was recorded in BaHajidu, which yielded 17.53 % over Werer-962, which had the lowest (1536.30 kg ha −1 ) numerical yield and was statistically inferior to the other varieties. The yield differences of these varieties could be due to their differences in genetic characteristics and the nature of agroecological adaptability, which is in agreement with the conclusions of Bale et al. (2011) who pointed out that seed yield differences among varieties were attributed to higher efficiency in the manufacture and partitioning of assimilates to the reproductive sink, which in turn led to more grain yield formation.…”

Effect of Sowing Windows on Growth and Yield of Groundnut (Arachis hypogaea L.) Genotypes

“…The pod yield decreased to 59.63 per plant with delay in sowing from II fortnight of June to I fortnight of August. The crop sown during II fortnight of June recorded significantly higher pod yield (15.20 q ha -1 ), which was due to favorable weather conditions prevailed during crop growth period and similar findings were reported by Canavar and Kaynak (2008) and Bala et al, (2011). Chandrika et al, (2008) reported that the effect of rainfall was greater on vegetative growth of the crop under late sown conditions.…”

Performance of Groundnut (Arachis Hypogaea L.) Varieties for Yield and Yield Components in Guji Zone, Southern Ethiopia

“…In addition, the highest seed weight in Baha-gudo could be most probably due to its efficient utilization of environmental growth resources so as to stimulate and enhance the photosynthetic and metabolic activities of the plant which resulted on the formation of healthy and well-structured seed. This result confirms the finding of Bale et al (2011) who pointed out that weight of dry pods plant-1 was significantly affected by variety x sowing date interaction. Moreover, Caliskan et al (2008) reported that both sowing date and cultivars significantly influenced 100-seed weight of groundnut…”

“…The lower (1211 & 1248 kg ha -1 ) numerical yield were obtained from Fayo and Nc-4x and statistically inferior to the other varieties respectively. The variation in marketable yield of these varieties could be due to their differences in genetic characteristics and agro ecological adaptability nature which is in line with the findings of Bale et al (2011) who pointed out that grain yield difference among varieties is attributed to more efficiency in the manufacture and partitioning of assimilates to the reproductive sink, which in turn led to more grain yield formation. In contrast to this result, Alemayehu et al (2014) reported that Sedi variety gave a shelled seed yield of 20.42 to 29.44 qt ha -1 in eastern and southern Ethiopia which related to the current finding.…”
