Depletion of phosphate rock reserves and world food crisis: Reality or hoax?

Phosphate rock (PR) deposits are the major source of phosphate (P) fertilizers for soil fertility replenishment. The demand for P fertilizers in the year 2014 was 42,706,000 tons and was expected to reach 46,648,000 tons in 2018. Majority of PR deposits are found in only a few countries including Morocco, USA and China. There is however conflicting information on the extent of world PR reserves, therefore, complicating...

Growth performance of royal purple and white guinea fowl varieties and their crosses under an intensive management system

Commercialization of guinea fowl production in many countries is growing and the demand for their meat is high. The study evaluated the growth of crossbred royal purple x white variety relative to purebred royal purple and white varieties. Twenty pure-bred white, 20 purebred royal purple and 20 cross-bred keets were housed together in 4 houses resulting in 4 replications. The keets were fed broiler starter crumbs from...

Pastoral farming system and its temporal shift: A case of Borana zone, Oromia National Regional State, Ethiopia

The study was conducted in Borana zone, which is located at about 570 km from Addis Ababa with the objective of understanding the farming system of Borana pastoral area. The primary data was collected using survey questionnaires from 160 households selected using multistage sampling design. The study confirmed that the farming system in Borana pastoral area has been increasingly diluted, unlike the earlier decades where...

Evaluation of blended fertilizer on growth performance and yield of onion (Allium cepa L.) at irrigated conditions Tselemti District North Western Tigray, Ethiopia

Onion has economically important crop in the study area. However, its low production is due to poor soil fertility management. Thus, the present study was initiated to determine the optimal rate of blended fertilizer required for onion production. A field experiment was conducted for two consecutive years during 2018 and 2019 at farmer's field Tselemti district, the experiment had 8 treatments arranged in a...

Household determinants of food security in rural Central Uganda

This study contributes to the literature by presenting empirical evidence on the drivers of rural household food security, which is critical for food security policy implementation. We used household survey data collected from 265 households from rural central Uganda, and a binary logistic regression model to estimate the determinants of household food security. Households with more land size, no livestock, and smaller...

Banana pest risk assessment along banana trade axes running from low to high altitude sites, in the Eastern DR Congo and in Burundi

Pests and diseases greatly contribute to the decline in banana yields, food and income insecurity in the Great Lakes region of Africa. Understanding people’s role in pest and disease spread at landscape level is crucial for effective pest and disease management. To determine this, focus group discussions (FGDs) targeting 10 experienced farmers (50% female and 50% male) were conducted in 27 villages along four...

Enhancing maize production in a Striga infested environment through weed management practices, sowing date and improved crop varieties

A two-year investigation into the effects of weed management practices, sowing dates and maize varieties was made in a Striga endemic field at Minna, Nigeria. The treatment was a factorial combination of variety (SAMMAZ 15, 17, 37, 40 and SUWAN-1-SR-Y), weed management practices (weedy check, two hoe weeding (HW) at 3 + 6 weeks after sowing (WAS), pre-emergence (PE) Atrazine at 2.4 kg a.i ha-1 + 1 HW at 6 WAS and PE...

Growth, physiology and yield of onion (Allium cepa L.) under salt stress

Onion production and productivity is constrained by biotic and abiotic factors. Soil salinity is one of the factors mentioned by producers in Ethiopia. Hence, the study was conducted to determine the relative tolerance of onion cultivars to salt stress levels under field condition on soil media filled in box at Melkasa Agricultural Research Center. Factorial combined treatments (4×5) were arranged in Randomized...
