Implementation of COVID-19 control measures: Effect on fertilizer supply and soil fertility in Africa
The unexpected outbreak of novel COVID-19 in late 2019 and continual spread across the world has disrupted the agricultural value chain. The World Health Organization (WHO) prescribed border closure, lockdown, social distancing, wearing a mask, and handwashing to combat the pandemic. These control measures, especially the closure of borders, have affected the importation and supply of fertilizer for crop production. The...

Phosphorus management issues for crop production: A review
Phosphorus (P) is an essential element for plant growth. On account of its low solubility in soil, P is often a limiting factor to optimum crop growth and therefore P fertilisation is an important aspect of nutrient management plans to ensure profitable and sustainable crop production. Plant P availability is controlled by sorption, desorption and precipitation of P from P released during weathering of P minerals and...

Agricultural zoning and recommendations for the seeding of wheat (Triticum species) in the Central-Southern Mesoregion of Parana State in Brazil
Wheat is one of the most cultivated cereals and is essential for human and animal feeding. Since it is a sensible species to the meteorologic conditions, the climate changes can alter all its cultivation areas and practices known in the present agriculture. This paper aims to make the zoning of climatic risk for agriculture for the wheat crop (Triticum species) and recommend the planting window for the central-southern...

Profitability analysis of smallholder cocoa production in South West Region of Cameroon
Over the years, cocoa production in Cameroon has served as a source of employment for many smallholder farmers. However, aging trees amongst other factors is a limiting factor in the productivity of cocoa. The study compared the economic performances of different crop ages of smallholder cocoa production using primary data obtained by means of semi-structured questionnaires. Multi-stage random sampling was adopted to...

Impact of row spacing on soybean morphological parameters and yield
The variable distribution of soybean seeds in rows can reduce the final stand and compromise grain yield. This article assesses the impact of seed distribution on the morphological characteristics of some plants and on the final yield of soybeans. The study was carried out in the experimental area of ??the federal university of Santa Maria, Frederico Westphalen campus, in the state of rio grande do sul, Brazil, in a...

Antioxidant activity of Capsicum frutescens and its effect on sensory and carcass traits of local chickens
This study determined the antioxidant activity of Capsicum frutescens powder and its effect on sensory and carcass characteristics of local chickens fed with either cotton seed cake or sunflower seed diets for thirty seven days. The birds were randomly assigned to four dietary treatments (0, 1.1, 2.2 and 4.4%) of C. frutescens powder. For cotton seed cake diets, 15 birds were replicated thrice per treatment whereas the...

Growth efficiency and profitability indices of African catfish (Clarias gariepinus) fingerlings fed with different levels of Adansonia digitata (Baobab) seed meal
The effects of diet with different inclusion levels of baobab seed meal inclusions on the growth and gross margin analysis of Clarias gaiepinus fingerlings was evaluated under a controlled laboratory condition. Five inclusion levels of Baobab Seed Meal (BSM) to replace soya bean meal were studied at 0, 5, 10, 15 and 20% dietary protein. The experimental diets were uniform by targeting 40% crude protein with energy level...

Study on the optimum nutrient solution concentration for the growth of Mint (Mentha genus)
Mint (Mentha genus) is an herbaceous herb that is fragrant useful for centuries with spices and medicinal herbs. Study on optimum nutrient solution sufficient to meet the plants’ demands regarding soilless culture of mint would be helpful for its application in plant factory, but was less reported. In the current study, 0.5 fold (×), 0.75×, 1.0× and 1.25× concentrations of Yamazaki formula...

Household welfare status and crop insurance uptake by cocoa farmers in Ondo State, Nigeria
This study examined the effect of welfare status on insurance uptake. The reason for the study is that formal insurance is still underutilized amongst farmers in Nigeria despite the incessant risk and uncertainties faced in agriculture. For this study, 200 households were randomly drawn from four local government areas of Ondo state through a 2-stage sampling technique. The analytical tools used were descriptive...

Use of positive selection technique to manage yam viruses in seed yam production by Ghanaian farmers
Positive selection technique (PST) involves physical examination of plants at vegetative stage for viral disease symptoms and using tubers from apparently symptomless plants as planting materials in seed yam production. This study determined PST use among farmers in Atebubu-Amantin and Ejura-Sekyedumase Municipalities of Ghana. Viral diseases were observed on 63 PST and 63 non-PST farms within these Municipalities. PST...
