“…In this regard, Ati et al [ 33 ] reported that the use of effective water management practices will help to address the global water crisis in the future thereby reducing wastage. Results of different researchers are also confirmed the results of the present study [ 4 , 7 , 34 ]. Nutrients contained in NPS fertilizer (nitrogen, phosphorous, and potassium) are essential nutrients taken up by potato plants in the greatest quantity and improve the growth and yield of potato and thereby improve the irrigation water use efficiency.…”

“…The average productivity of teff in Ethiopia is very low (1.85 t/h) at the smallholder farmer level. The main reason for low teff productivity is nutrient deficiency, susceptibility to lodging (Habtegebrial et al, 2007), low genetic yield potential (Haileselassie et al, 2016), and drought, particularly in the low altitude.…”

Plant growth-promoting rhizobacterial inoculation to improve growth, yield, and grain nutrient uptake of teff varieties

et al. 2022

Inoculation of plant growth-promoting rhizobacteria (PGPR) improves the growth, yield, and plant nutrient uptake, as well as rhizosphere fertility, without harming the environment and human health. This study aimed to examine the effect of either individual or consortium of PGP bacterial inoculation on the growth, yield, and grain nutrient uptake of teff varieties. Three potential PGPR strains (i.e., Pseudomonas fluorescens biotype G, Enterobacter cloacae ss disolvens, and Serratia marcescens ss marcescens) were used for this study. Field evaluation was carried out in RCBD with 5 treatments. Highly significant (P < 0.001) differences were observed among treatments for plant height (PH), panicle length (PL), number of the total spike (NTS), shoot dry weight (SDW), grain yield (GY), and straw yield (SY). There was also teff variety that significantly (P < 0.01) affects PL, SDW, and SY. However, the interaction effect of the two factors (treatment*variety) did not significantly influence teff agronomic traits and grain nutrient uptake. The highest PH (133.5 cm), PL (53.2), NTS (30.9), SDW (18.1 t/ha), SY (10.7 t/ha), and GY (2.7 t/ha) were observed on Dukem variety (Dz-01-974) inoculated with PGPR consortium. Wherein 2.2 fold increase was observed in grain yield per hectare over the control. Inoculation of PGPR consortium showed better performance in promoting plant growth, yield, and grain nutrient uptake of teff varieties compared with the individual PGP bacterial application, and PGPR consortium could be used as inoculants to enhance teff production and productivity.

“…This limits its application in Ethiopia, where soil degradation [15] and low levels of fertilizer use [16] cause nutrient limited growing conditions. In addition, the AquaCrop tef model was not developed to take differences in daylength into account [1,13,[17][18][19], limiting its application to low latitudes.…”

Tef is an Ethiopian staple grain that provides both food security and income for smallholders. As tef is nutritious and gluten free, it is also gaining popularity as a health food. A tef model was calibrated based on the Decision Support System for Agrotechnology Transfer’s (DSSAT) NWheat model and included parameter changes in phenology, photoperiod response, radiation use efficiency, and transpiration efficiency for both standard and elevated atmospheric CO2, based on published literature for tef and other C4 species. The new DSSAT-Tef model was compared with tef field experiments. DSSAT-Tef accurately simulated phenology and responded to changes in N supply and irrigation, but overestimated growth and occasionally yields. Simulation-observation comparisons resulted in an RMSE of 2.5 days for anthesis, 4.4 days for maturity, 2624 kg/ha (49.6%) for biomass, and 475 kg/ha (41.0%) for grain yield. Less data were available for N uptake, and the model simulated crop N uptake with an RMSE of 45 kg N/ha (46.2%) and 15 kg N/ha (37.3%) for grain N. While more data from contrasting environments are needed for further model testing, DSSAT-Tef can be used to assess the performance of crop management strategies, the suitability of tef for cultivation across growing environments, and food security.
