Cultural practices and pesticides contamination level of tomato in two gardening sites in the region of Boucle du Mouhoun, Burkina Faso

The present study consisted of evaluation of cultural practices and pesticides contamination level of tomato in some gardening sites in the region of Boucle du Mouhoun (Burkina Faso). A survey of phytosanitary practices among 30 producers was carried out at the Di and Dedougou sites. The pesticide contamination level of tomatoes collected was determined by the QuEChERS method. The survey revealed a low level of literacy...

Evaluation of a motorized cassava peeler with four lining materials

Cassava processing requires peeling, which is mainly done manually and not effective for large scale processing, hence, the need to mechanise the peeling process. A motorized cassava peeler with four drum and disc linings (concrete, metal, rubber and wood) was designed. The prototype was tested at three disc speeds; (250, 350 and 500 rpm) to determine peeling capacity, peel removal efficiency, and flesh loss. The...

Comparing productivity of rice under system of rice intensification and conventional flooding: A switching regression approach

This paper examined the factors influencing rice productivity in Mwea Irrigation Scheme using the System of rice intensification (SRI) and conventional flooding (CF). Stratified sampling was used to obtain 364 smallholder rice farmers for interviewing. Data collection was done with the aid of a semi-structured questionnaire and analyzed using the Endogenous Switching regression Model (ESRM).  The results of ESRM...

Agronomic and economic evaluation of phosphate fertilizer use in maize-bean cropping systems in Western Kenya

Effects of phosphorus rate and crop arrangement on yields and economic benefits in maize-bean cropping systems were investigated for two seasons: Short rains (SR) of 2015 and long rains (LR) of 2016 in Western Kenya. A split plot design with five crop arrangements in the main plots; one row of maize and beans alternating (conventional), maize and beans planted in the same hole (SH), two rows of maize alternating with...

Leaf organic content variation of 2 durum wheat genotypes under water stress by applying phytohormone (IAA)

Water stress is the most important problem in plant growth and development. Greenhouse trial is carried out on 2 durum wheat (Triticum durum Desf) genotypes (MBB and WAHA), to evaluate the effect of water stress on the biochemical content of leaves, and the possibility of reducing this effect by applying a growth regulator Indole-3-acetic acid (IAA) by seeds soaking and foliar spraying. Water stress causes a large...

Biofortified bean genotypes under integrated soil fertility management across sub-humid agro-ecological zones of The Democratic Republic of Congo

This study was implemented to evaluate the performance of biofortified bean under different integrated soil fertility management (ISFM) options and agro-ecological conditions in Democratic Republic of Congo (DRC). A Split-plot design with eight genotypes as main factors and four ISFM options as secondary factors was carried out in eight production zones distributed across South-Kivu, North-Kivu, and Katanga provinces....

Response of eight sorghum varieties to plant density and nitrogen fertilization in the Sudano-Sahelian zone in Mali

This work was conducted to study the performance of eight sorghum varieties that contrasted with intensified practices in the Sudano-Sahelian zone of Mali. Two experiments were carried out in 2018 and 2019 rainy seasons at Sotuba Agricultural Research Station in Mali. The experimental design used was a Split-split-plot with three replications and three factors including two plant densities (D1: 26666 plants ha-1 and D2:...

Challenges in greenhouse crop production by smallholder farmers in Kisii County, Kenya

Despite the success in greenhouse farming by large scale horticultural farmers in Kenya, smallholder greenhouse farming is beset by many challenges leading to over 30% failure rates. Reasons for the high failure rate are not clearly understood. The objective of this study was to assess the challenges in greenhouse crop production by small-scale farmers in Kisii County, Kenya and provide recommendations for sustained...

Determination of solar energy requirements for indirect cooling combined with evaporative cooling for storage of fresh produce

A solar photovoltaic (SPV) system generating power to run a 53-m3 storage for indirect air-cooling combined with evaporating cooling (IAC+EC) for providing a cool environment for storage of tomatoes under small-scale farming was evaluated. The experiment consisted of nine 330 W solar modules, twelve 230 AH Gel batteries, 145 VDC solar charge controller, 5 kW inverter, 290 W ventilation fan, 260 W water pump,...

Field evaluation of lentil germplasms for their resistance to Ascochyta blight (Ascochyta lentis) under field conditions

Ascochyta blight caused by Ascochyta lentis has the potential to cause appreciable reduction in yield. The present study was conducted to identify the sources of resistance in lentil to ascochyta blight in 2017/2018 main cropping season in hot spot area in AlemTena Research Station. The total of 148 lines accession received from Ethiopian Biodiversity Institute were grown in augmented design without replications that...

Genetic diversity analysis and construction of selection index of selected tomato genotypes

To study the genetic variability and selection index of selected tomato genotypes, an experiment was conducted at the farmer’s field of Chirirbandar Upazilla of Dinajpur District, Bangladesh. Ten tomato genotypes were evaluated in a randomized completely block design with four replications. The study results displayed high heritability plus higher genetic advance for all the traits studied. Among the traits, plant...

The use of microchondrometer to assess test weight in small samples of triticales and oats

The test weight or hectoliter weight is an important parameter used to classify the quality of the grain. Globally, it is evaluated by using 250, 500 or 1000 ml devices. Despite its importance, there is no standard equipment to assess it in small samples from the research plots. This study aims to test a newly developed microchondrometer (15.30 ml) in the triticale and oats. A second microchondrometer (31.26 ml) was...

Effect of kernel type on hardness and interrelationship with endosperm chemical components of Malawian local maize (Zea mays L.) varieties during storage

The aim of this study was to establish the attributes of kernel type based on kernel hardness and its interrelationship with maize endosperm chemical components, which are essential during storage. Three local varieties and one hybrid variety commonly grown by smallholder farmers in central Malawi were used. For storage experiment, the maize samples were infested with Prostephanus truncatus, larger grain borer (LGB) for...

Effect of nitrogen rate and intra-row spacing on yield and yield components of maize at Bako, Western Ethiopia

Maize is highly responsive to nitrogen fertilizer rates and plant spacing. Continuous efforts have been carried out to improve the yield potential of maize by modifying their architecture through breeding methods with aim of increasing maize yield through increasing number of plants ha-1. Hybrid BH-546 is the recently released variety for this purpose but its optimum nitrogen rate and spacing has not been determined...

Gene action analysis studies for agronomic traits in cassava (Manihot esculenta Crantz) genotypes developed using line by tester mating design

Despite the significance of cassava as food, feed and industrial root crop, little is known regarding the gene action determining root dry matter content (RDMC), fresh root yield, and tolerance to cassava mosaic disease (CMD), cassava green mite (CGM), and cassava mealy bug (CMB). Thus, a study was conducted to determine the general and specific combining abilities for disease, pest, RDMC, root yield and related traits...
