| Abstract |
Sweet potato [Ipomoea batatas (L) Lam] yields currently stand at 4.5 t ha(-1) on smallholder farms in Uganda, despite the attainable yield (45-48 t ha(-1)) of NASPOT 11 cultivar comparable to the potential yield (45 t ha(-1)) in sub-Saharan Africa (SSA). On-farm field experiments were conducted for two seasons in the Mt Elgon High Farmlands and Lake Victoria Crescent agro-ecological zones in Uganda to determine the potential of biofertilizers, specifically arbuscular mycorrhizal fungi (AMF), to increase sweet potato yields (NASPOT 11 cultivar). Two kinds of biofertilizers were compared to different rates of phosphorus (P) fertilizer when applied with or without nitrogen (N) and potassium (K). The sweet potato response to treatments was variable across sites (soil types) and seasons, and significant tuber yield increase (p < 0.05) was promoted by biofertilizer and NPK treatments during the short-rain season in the Ferralsol. Tuber yields ranged from 12.8 to 20.1 t ha(-1) in the Rhodic Nitisol (sandy-clay) compared to 7.6 to 14.9 t ha(-1) in the Ferralsol (sandy-loam) during the same season. Root colonization was greater in the short-rain season compared to the long-rain season. Biofertilizers combined with N and K realized higher biomass and tuber yield than biofertilizers alone during the short-rain season indicating the need for starter nutrients for hyphal growth and root colonization of AMF. In this study, N0.25PK (34.6 t ha(-1)) and N0.5PK (32.9 t ha(-1)) resulted in the highest yield during the long and the short-rain season, respectively, but there was still a yield gap of 11.9 and 13.6 t ha(-1) for the cultivar. Therefore, a combination of 90 kg N ha(-1) and 100 kg K ha(-1) with either 15 or 30 kg P ha(-1) can increase sweet potato yield from 4.5 to >30 t ha(-1). The results also show that to realize significance of AMF in nutrient depleted soils, starter nutrients should be included. |

Attention Score in Context
This research output has an Altmetric Attention Score of 1. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 06 March 2018.
All research outputs
#18,540,642
of 22,962,258 outputs
Outputs from Frontiers in Plant Science
#13,890
of 20,389 outputs
Outputs of similar age
#235,673
of 308,534 outputs
Outputs of similar age from Frontiers in Plant Science
#389
of 530 outputs
Altmetric has tracked 22,962,258 research outputs across all sources so far. This one is in the 11th percentile – i.e., 11% of other outputs scored the same or lower than it.
So far Altmetric has tracked 20,389 research outputs from this source. They receive a mean Attention Score of 4.0. This one is in the 20th percentile – i.e., 20% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 308,534 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 12th percentile – i.e., 12% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 530 others from the same source and published within six weeks on either side of this one. This one is in the 19th percentile – i.e., 19% of its contemporaries scored the same or lower than it.
