Quality of Soil in the function of biological fertilization and plant covering

The yield of soybean was influenced by the chemical and microbiological properties of the soil, which was favored by management techniques that promote improvement in soil quality. The objective of this study was to evaluate soybean yield, chemical and microbiological quality of the soil as a function of biological fertilization and soil cover conditions. The experiment was conducted in both crops seasons 2015/16 and...

A survey of the insect pests and farmers’ practices in the cropping of yellow pepper Capsicum annuum Linnaeus in Enugu State of Eastern Nigeria

Yellow pepper (Capsicum annuum L.) is the second market gardening crop after tomato, and subsequently, a major source of income to farmers in Nigeria. Pests and diseases reduce yields and quality of marketable fruits. A study was conducted in Ibagwa-Agu, Lejja, Edem, Alor-Uno and Eha-Alumona agro-based communities of Nsukka Local Government Area to assess the economic implications of insect infestation and control...

Seed health tests of traditional leafy vegetables and pathogenicity in plants

Traditional leafy vegetables play a significant role in the daily diets of many people in Zimbabwe. They are produced by smallholder farmers with limited knowledge on the agronomic value of high-quality seed, on seed storage, and on plant- and seed-borne pathogens. The quality of the seed is rarely tested for seed-borne pathogens posing risks of pathogen build-up. This study was conducted in order to determine the...

Soybean development under soil water deficit

One of the main factors affecting soybean development is water deficiency, especially when it occurs during the flowering and pods filling stages. Thus, this study aimed to evaluate the soybean development under soil water deficit in different phenological phases, under soil and climatic conditions of Bom Jesus, Piaui State, Brazil. The test was conducted at São Luiz Farm, located 3 km from Bom Jesus  to...

Rice farmers’ perception of climate change and adaptation strategies in the Ketu North District, Volta Region of Ghana

This study assessed rice farmers’ perception of climate change and adaptation strategies in the Ketu North District, Volta Region of Ghana. Climate variables particularly precipitation and temperature were taken in the climate change perception study. Multistage sampling technique was used to select 340 rice farmers from six farming sections, and a structured questionnaire was used to elicit data from the...

Cropping systems and soil quality and fertility in south-central Uganda

Little is known about how cropping systems influence soil quality and fertility in Uganda. Some cropping systems are more valued and as a result are given more nutrients and planted in certain soils, all of which leads to varying soil quality and fertility. This study compared soil quality (soil pH, cation exchange capacity (CEC), electric conductivity (EC), total N, and depth to restrictive layer (DRL)) and fertility...

Bacaba-de-leque (Oenocarpus distichus): A new wet tropics’ nutritional source

The present study aims to determine the nutritional composition of soluble and insoluble fibers, vitamins and minerals in the fruit of bacaba-de-leque (Oenocarpus distichus Mart.) a native Central Amazonian tropical fruit. Results show the fiber contents to be 3.95 g 100 g-1, 100% of which shows to be insoluble fibers. Potassium stood out among the minerals, with 173.85 mg 100 g-1. High vitamin E concentration (6.65 mg...
