“…Badawi et al [32] reported that Rh inoculation resulted in 40.58% and 21.02% higher shoot and root dry weights, respectively, over the uninoculated plants. Other previous studies have also demonstrated that leguminous crops have positive and higher correlations with basal applications of the recommended dose of N applied concurrently with Rh inoculants in different geographic locations [33,34]. Supplementing with Rh increases the readily available nutrients to plants; in the absence of this symbiotic N, plants must expend more energy taking up nitrate and reducing it to a more useable form (i.e., NH3), which lowers the potential dry matter accumulation [35].…”

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.

Soils were collected from sixty farms of Siaya County where low soybean response to inoculation was observed [25, 84] (Fig 1) (where a varied response to an ISFM soybean package had been observed) at a depth of 0‒20 cm, air dried, and thoroughly mixed to pass through a 2-mm sieve. Subsamples were analyzed for physical, chemical, and microbiological properties prior to planting.…”

2 11 Abstract 12 Rhizobia inoculation can increase soybean yield, but its performance is influenced by soybean 13 genotype, rhizobia strains, environment, and crop management among others. The objective of 14 the study was to assess soybean response to rhizobia inoculation when grown in soils amended 15 with urea or Vermicompost to improve nitrogen levels. Two greenhouse experiments and one 16 field trial at two sites were carried out. The first greenhouse experiment included soils from sixty 17 locations, sampled from smallholder farms in Western Kenya. The second greenhouse 18 experiment consisted of one soil selected from soils used in the first experiment where 19 inoculation response was poor. The soil was amended with Vermicompost or urea. In the two 20 greenhouse experiments, Legumefix® (inoculant) + Sympal (legume fertilizer blend) were used 21 as a standard package. Results from the second greenhouse experiment were then validated in the 22 field. In the first greenhouse trial, soybean response to inoculation was significantly affected by 23 soil fertility based on nodule fresh weight and shoot biomass. Soils with low nitrogen had low to 24 no response to inoculation. After amendment, nodule fresh weight, nodule effectiveness, nodule 25 occupancy, and shoot dry biomass were greater in the treatment amended with Vermicompost 26 than those amended with urea (Legumefix® + Sympal + Vermicompost and Legumefix® + 27 Sympal + urea). Under field conditions, trends were similar to the second experiment for 28 nodulation, nodule occupancy, and nitrogen uptake resulting in significantly greater grain yields 29 (475, 709, 856, 880, 966 kg ha -1 ) after application of Vermicompost at 0, 37, 74, 111, and 148 kg 30 N ha -1 , respectively. It was concluded that soybean nodulation and biological nitrogen fixation in 31 low fertility soils would not be suppressed by organic amendments like Vermicompost up to 148 32 kg N ha -1 . 33 Keywords: Rhizobia inoculation, nodule occupancy, nodule effectiveness, Vermicompost, grain 34 yield. 3 36 Introduction 37 Soybean (Glycine max L. Merr) is one of the world's most important legumes in terms of 38 production and trade and has been a dominant oilseed since the 1960s [1]. The crop is well 39 known for its high protein content (about 40%) [2]. Additionally, it can improve soil properties 40 and soil biological health by soil nitrogen enrichment through N 2 fixation and subsequent 41 mineralization of shoot and root biomass [3]. It therefore represents a significant opportunity in 42 sub-Saharan Africa (SSA), where over 80% of the soils are nitrogen deficient [85], and over 39% 43 of the children under 5 years are stunted because of malnutrition caused by nutrient deficiency, 44 particularly proteins [4], contributing to over one third of child deaths [5]. Integration of soybean 45 in smallholder farming systems would thus not only improve human nutrition when the crop is 46 included in diets but also soil productivity. Such benefits would materialize when good 47 agronomic practices...
