“…Farmers in the study area reported poor soil fertility as the next yield-limiting factor in groundnut production. Anteneh (2017) reported low soil fertility status as one major abiotic constraint to sustainable groundnut production in the same study areas, which is in agreement with the present study. Groundnut diseases, such as root rot and leaf spot, are among the most important biotic factors that limit groundnut production.…”

“…It has a predominantly welldrained sandy loam soil that is ideal for groundnut production. The rainfall distribution of the area is bimodal, with the main rain (locally referred to as Meher rain) received during July to October and short rain (locally known as Belg rain) during March to May (Anteneh 2017). The mean annual maximum and minimum temperatures are 28.1°C and 15.5°C, respectively, with the total annual rainfall ranging from 507 to 984 mm.…”

Groundnut (Arachis hypogaea L.) is an important food and cash crop globally. The eastern region of Ethiopia is known for its groundnut production despite the low productivity attributable to diverse biotic and abiotic stresses and socioeconomic constraints. The objective of this study was to assess farmers' perceived production constraints, variety choice, and preferred traits of groundnut in eastern Ethiopia to guide future groundnut variety development and release. Participatory rural appraisal studies were conducted in two major groundnut-producing districts (Babile and Fedis) in eastern Ethiopia. Data were collected through a semi-structured questionnaire, transect walks, and focus group discussions. All respondent farmers widely cultivated local or obsolete, introduced varieties because of a lack of seed of modern groundnut cultivars. Ninety percent of respondents reported drought stress, mainly occurring during the flowering stage, as the leading constraint to groundnut production. Other groundnut production constraints included poor soil fertility (reported by 88% of respondents), lack of access to improved seed (67%), pre-harvest diseases (59.5%), use of low yielding varieties (52.5%), inadequate access to extension services (41.5%), limited access to credit (21.5%), and limited availability of improved varieties (18.5). Farmer-preferred traits included high shelled yield (reported by 27.67% of respondents), early maturity (16.84%), tolerance to drought stress (13.67%), market value (11.17%), good seed quality (10%), adaptability to local growing conditions (5.8%), and resistance to diseases (5.17%). Therefore, the aforementioned production constraints and farmer-preferred traits are key drivers that need to be integrated into groundnut breeding and variety release programs in eastern Ethiopia.

100 countries over 22 × 10 6 ha in the tropical and sub-tropical countries (Ahmed et al., 2016). Peanut productivity in tropical countries, including Indonesia, India, and countries in Africa, is generally almost the same, between (0.7 to 1.3) t ha -1 of dry pods (Sumarno, 2015). Kementerian Pertanian (2017) reports that productivity of peanuts has fluctuated throughout 5 year in the period 2013 to 2017 with the average productivity of 1.318 t ha -1 . Peanut productivity in Indonesia is relatively low, compared to USA, China, Australia and Argentina, which have reached more than 2 t ha -1 (Kurniawan et al., 2017;Sumarno, 2015). The efforts to increase peanut production are carried Abstract | Peanut plants use nitrogen sources from the atmosphere with the help of Rhizobium bacteria. Rhizobium was requiring P elements for root nodules formation. This study aims to determine the effects of the application of mycorrhizae at different levels that play an essential role in increasing P elemental uptake and rhizobia inoculants to improve N element fixation and root nodule formation. Rhizobia inoculant applications were allotted to main plots and levels of mycorrhizae to the subplots under each main plot. Three types of rhizobia applications viz., soaking (A1), spraying (A2), soaking and spraying (A3) and four levels of mycorrhizae doses viz., 0 g plant -1 (M0), 10 g plant -1 (M1), 15 g plant -1 (M2), 20 g plant -1 (M3). The results indicated that the application of Rhizobium at various doses of mycorrhizae together had a significant effect on plant height 70 d (A2M1 = 53.96 cm), leaf number 70 d (A1M3 = 42.75), leaf N content (A3M3 = 5.36 g 100 g -1 ), leaf P content (A3M3 = 0.418 g 100 g -1 ), leaf K content (A3M3 = 0.273 g 100 g -1 ), number of root nodules (A3M0 = 120), and weight of fresh pods plant -1 (A1M3 = 33.67 g). That application can enhance root nodules and had increased NPK uptake.

“…Therefore, supplementing N fertilizer with biofertilizer such as Rh has been widely proposed, with the aim of increasing the efficiency with which the peanut plant takes up the applied mineral N, as the biofertilizer assists mobilization of soil organic N into plant-available inorganic forms, and also facilitates fixation of atmospheric N within the soil [18]. The legume-Rh symbiosis is one of the most well-known plant microorganism interactions, and accounts for almost 41 kg N ha −1 added into soils annually in peanut cultivation [19]. Argaw [20] reported significant increases in peanut dry matter, nodule number, grain yield and plant N uptake in eastern Ethiopia when N was applied at intermediary rates (20 kg ha −1 ) and combined with Rh inoculation as compared to no N and Rh application.…”

Peanut (Arachis hypogaea L.) is adorned as the one of the important sources of vegetable oil, protein, vitamins and several minerals, which could mitigate the nutritional gap worldwide. However, peanut cultivation in winter suffers from low temperature stress and knowledge lacuna regarding the optimum dose nitrogen. Therefore, the present investigations were carried out during the winter seasons 2015–2016 and 2016–2017 at the district seed farm of Bidhan Chandra Krishi Viswavidyalaya, an agricultural university in West Bengal, India (23°26’ N, 88°22´ E, elevation 12 m above mean sea level) to facilitate the comprehensive study of plant growth, productivity and profitability of an irrigated peanut crop under varied levels of nitrogen: with and without a rhizobium inoculants and with and without polythene mulch. Quality traits and nutrient dynamics were also itemized. Fertilizing with 100% of the recommended dose of nitrogen combined with rhizobium inoculant and polythene mulch significantly enhanced peanut plant growth, yield and yield-attributing traits, while resulting in the maximum fertilizer (i.e., nitrogen, phosphorus and potassium) uptake by different plant parts. The greatest number of root nodules occurred in the treatment that received 75% of the recommended dose of nitrogen with rhizobium supplementation under polythene mulch, while 50% of the recommended dose of nitrogen with no rhizobium resulted in maximum fertilizer nitrogen use efficiency. Applying the full recommended dose of nitrogen with the rhizobium inoculants and mulch resulted in maximum profitability in the peanut crop.
