Responses of Bambara groundnut [Vigna subterranea (L.) Verdc.] to Phosphate Fertilizer Rates and Plant Spacing and Effects on Soil Nutrient Statues in a Degraded Tropical Ultisol Agbani Enugu South East Nigeria

Abstract

The agronomic practices such as plant spacing and phosphate fertilizer requirements for the cultivation of Bambara groundnut [Vigna subterranea (L.) Verdc.] have not yet been fully determined in Agbani agro ecology South east Nigeria. Field trials were conducted in 2015 and 2016 planting season at the Teaching and Research Farm of the Faculty of Agriculture and Natural Resources Management, Enugu State University of Science and Technology, Agbani as a 4 x 3 factorial experiment in randomized complete block design with three replications. The treatments were four rates of single super phosphate fertilizer (0 kg P ha -1

Growth, Yield, Nodulation and Amino Acid Content of Bambara Groundnut (Vigna subterranea) under Inorganic and Organic Fertilizer Application

“…Treatment T 1 (N 30 + P 60 kg/ha) (49.67 g) also produced the highest pod weight and T 4 (compost 2.5 t/ha) (34.95 g) was the lowest. These result was quite dissimilar with Ikenganyia et al (2017) because they used the dose of single super phosphate (0, 25, 50, 75 kg/ha). The difference observed between the treatments was because, in the organic residues, nutrient availability depended on nutrient concentration and release with synchrony with crop needs.…”

Revitalizing cultivation and strengthening the seed systems of fonio and Bambara groundnut in Mali through a community biodiversity management approach

“…Nevertheless, fertilizer and better crop care (timely weeding) supported good production levels in the diversity fields and it is possible these practices were applied by farmers in their own fields. Optimal spacing and weeding are known to significantly improve Bambara groundnut yields (Akpalu et al ., 2012; Banta and Sodangi, 2016; Ikenganyia et al ., 2017). Nitrogen fertilization during early crop growth and phosphorus fertilization also raise yields of this crop (Ikenganyia et al ., 2017; Temegne et al ., 2018), while it is unlikely farmers were applying fertilizer to Bambara groundnut in their fields because it is generally prioritized for cereals (Laris et al ., 2015; Dembele et al ., 2016).…”

The more moderate difference in fonio yield between the diversity fields and household production could relate to the use of broadcast sowing, which is less productive than drill sowing (Dachi et al ., 2017), or suboptimal nitrogen, phosphorus and potassium fertilizer ratios (Gigou et al ., 2009), among other factors.…”

Origin and Ecology of Bambara Groundnut (Vigna Subterranea (L.) Verdc: A Review

“…The work of Temegne showed that 150 kg.ha -1 simple superphosphate is needed for the production of Bambara groundnut on the poorer Ferralsols in the Centre Region of Cameroon [5]. Other studies in Nigeria have also shown that phosphate fertilization improves the growth and yield of Bambara groundnut [53][54][55]. The soluble P input improved its growth in the greenhouse; while biological fertilization with arbuscular mycorrhizal fungi significantly boosted its growth, development and yield in Cameroon [4,5,[47][48][49].…”
