Role of income from rice cultivation on livelihoods of rice farmers: Evidence from Ahero Region, Kenya

In Africa, the demand for rice has increased rapidly as urbanization progresses and assistance is being provided to improve productivity and rice farming management. In the rice-cultivation area near Lake Victoria in western Kenya, where farmers are called “outgrowers”, wage labor costs put pressure on rice farming and reduce profits. However, wage laborers were rice farmers living in the same area. The...

Effects of corn-pea mixture and harvesting days on forage yield and quality

The objective of this study was to assess the effect of mix-cropping, Yangtsepa corn variety with legume Sesbania, and single cropping on the forage yield and quality at 60-, 90-, and 120-days harvest. Randomized Complete Block Design (RCBD) with three replications was used as an experimental design. The corn and pea were line sown at 20 cm apart with a seed ratio of 50:50. The results showed higher corn forage yield...

Yields and soil chemical property changes in an intensive vegetable cropping system in the Sahel

Irrigated vegetable production is an important agricultural activity and a significant source of income for millions of smallholder farmers in the Sahel. There is little information on the potential effects of intensive vegetable production using African Market Garden (AMG) technology on vegetable yields and soil chemical properties. Three contiguous 500-m2 plots were established to evaluate three vegetable management...

Nitrogen effects on leaf gas exchange, vegetative growth and yield of black pepper plants using Gliricidia sepium as living support

For the implantation of one hectare of black pepper (Piper nigrum), about 25 to 30 trees are removed from the Amazon Forest to produce tutors for black pepper. As an alternative to the dead wooden stake (WS), there is sustainable cultivation of black pepper with tree species, with the living supports (LS) of gliricídia (Gliricidia sepium L.). However, there is inadequate technical information on the effect of...

Species of the Corchorus genus: Identification, nomenclature and socio-economic role in Burkina Faso

Indigenous leafy vegetables play a significant socio-economic role for the local population. However, most of them used at the local level have not been studied a lot and their nutritional values are less implemented. This study focuses on the local nomenclature and the socio-cultural services of the species of Corchorus genus. Therefore, a collection followed by an ethnobotanical survey was carried out in 22 provinces...

Bacillus subtilis UFMT-Pant001 as a plant growth promoter in soybean in a greenhouse

This study aims at evaluating the agronomic efficiency of the Bacillus subtilis UFMT-Pant001 strain as a plant growth promoter in soybean at three greenhouses from distinct Brazilian regions. The treatments were formulated based on this strain at a concentration of 1x109 UFC.mL-1 in volumes of 100, 150, 200, 250, 300, 350 or 400 mL for each 50 kg of seeds. Bradyrhizobium japonicum was added in all experiments, and the...

Depth and soil physiochemical properties effects on soil compaction in agricultural field

Physical and chemical properties of the soil are key determinants of farm soil compaction. The purpose of this study is to study the effects of depth and soil physiochemical properties on soil compaction. Soil compaction was measured using a Spot On digital compaction meter. During the soil compaction field test five different depths were selected. In the soil laboratory, soil texture, soil pH, soil electric...

Effect of manure-based biochar amendment on soil chemical properties, total enzymic activities and tomato growth performance in acidic soil under controlled conditions

The aim of this study is to evaluate the effect of biochar on tomato production under controlled conditions. Trials were installed using a complete randomized block design (CRD) with 5 replications of 4 treatments: T0 (0%); T1 (8%); T2 (12%) and T3 (16%). During plant growth, parameters including height, diameter, number of leaves, number of fruits and plant biomass were collected. Plants obtained from pot that received...

Factors influencing choice of milk market outlets among smallholder dairy farmers in Kuresoi north sub-county, Kenya

Kuresoi North Sub-County has experienced a rapid expansion in milk production and there exist both formal and informal milk market outlets. With these abundant opportunities, much of the produced quantities of milk are expected to enter the market and farmers’ livelihoods be improved. However, it is not clear whether the smallholder milk producers are exploiting the existing and emerging market opportunities...

Response of spring wheat (Triticum aestivum L.) cultivars to ridge -furrow tillage systems

Tillage system is one of the main factors influencing growth and physiology of wheat (Triticum aestivum L.), that eventually translates to high yield and good kernel quality. The objectives of this study were to determine the effects of the ridge (RT) and flat tillage (FT) systems on (i) growth and production of spring wheat, (ii) root growth and physiology and (iii) soil physical properties. Trials were conducted at...

Effects of cricket frass on vegetative growth of Cleome gynandra

Insect farming as food and feed has gained popularity. Insects require less land and water and are efficient in feed-food conversion, making them a sustainable alternative source of protein for food fortification and feed formulation. Some insects play a vital role in bio-remediation of organic waste as they feed on waste breaking it down to frass that has the potential to be used as an organic fertilizer in food...
