Objective: To investigate the relation of child dietary diversity and household food insecurity along with other socio-demographic with child anthropometric indices in north-central Ethiopia, an area with a high level of food insecurity and inadequate diet quality. Design: A community-based cross-sectional study was used. Settings: The study was conducted in Dessie and Combolcha towns of north-central Ethiopia from April to May 2018. Participants: Randomly selected 512 mother-child pairs with child’s age range of 6–59 months. Results: The mean (± SD) scores of weight-for-height/length, height/length-for-age, weight-for-age, and BMI-for-age Z-scores were 1.35 (± 2.03), − 1.89 (± 1.79), 0.05 (± 1.54), and 1.39 (± 2.06), respectively. From all anthropometric indicators, stunting and overweight/obesity remained the severe public issues hitting 43% and 42% of the children, respectively. In the model, mothers’ age and education and child’s age, sex, and dietary diversity were significantly related with child height-for-age Z-score while place of residence, sex of household head, child’s age, and dietary diversity score were the predictors of child BMI-for-age Z-score in the urban contexts of the study area. Nevertheless, food insecurity was not related to any of the child anthropometric indices. Conclusion: The double burden of malnutrition epidemics (stunting and obesity) coexisted as severe public health concerns in urban settings. Anthropometric statuses of children were affected by multidimensional factors and seek strong integration and immediate intervention of multiple sectors.

In Ethiopia, the average yield of potato is far below the potential due to different problems like in low soil fertility. Hence, this research was done to evaluate the effects of blended NPS fertilizer rates on yield and yield components of potato. The study was conducted at Abaso Kotu, Dessie Zuria district, Ethiopia, during dry season of 2015. The experiment was consisted a factorial combination of two late maturing potato varieties (Belete and Local) and six NPS fertilizer rates (0:0 (T1), 111:89.7:0 (T2), 111:89.7:16.52 (T3), 55:89.7:16.52 (T4), 111:44.85:8.26 (T5) and 55:44.85, 8.26 (T6)) kg ha-1 and Randomized Complete Block Design with three replications was used. The highest potato plant height was recorded on 111: 89.7:16.52 (T3) kg ha-1 of NPS fertilizer rate. Belete variety supplied with 111: 89.7:16.52 (T3) kg ha-1 of NPS fertilizer rate recorded the maximum days (124.3) to maturity of potato. Similarly, Belete variety recorded the higher biomass than local variety. The 111:89.7:16.52 (T3) kg ha-1 and 55.5:89.7:16.52 (T4) kg ha-1 NPS fertilizer rates showed the highest above ground biomass and underground biomass of potato, respectively. The highest average tuber number per hill, tuber weight per hill, marketable, unmarketable and total tuber yield were recorded on potato which was applied with 55.5: 89.7:16.52 (T3) kg ha-1 of NPS fertilizer rate. It is concluded that 55.5:89.7:16.52 (T4) kg ha-1 NPS fertilizer rate application is recommended for the production of potato varieties at Abaso Kotu, Dessie Zuria District Ethiopia.

The experiment was conducted to determine the effect of integrated postharvest chemical, packaging and storage treatments on weight loss and sugar content of cactus pear fruits. The treatments were factorial combinations of chemical (Control, 0.022 mM Salicylic Acid, and 27 mM CaCl₂), two packaging (unpackaged and packaged with polyethylene sheet) and two storage condition (ambient and evaporative cooler (EC)) in completely randomized design with three replications. Temperature and relative humidity of storage environments, weight and decay loss, and reducing and total sugar content of cactus pear fruits were recorded during 21 days of storage. EC significantly maintained parameters of cactus pear fruits tested by reducing mean temperature 2.81°C and increasing relative humidity by 11%. Packaging also reduced weight and decay loss and maintained sugar contents. Similarly, CaCl₂ treatment enabled better retention of weight and sugar content of cactus pear fruits followed by Salicylic acid. Hence, integrated use of CaCl₂, packaging and EC are recommended to maintain lower weight and decay loss and higher reducing and total sugar contents and to extending shelf life of cactus pear fruits.
