Floral activity of Chrysomya putoria Wiedemann, 1830 (Diptera: Calliphoridae) enhances the pollination and fruit set rate of Ricinus communis L., 1753 (Euphorbiaceae)

Experiments were conducted to study the foraging behaviour of blowfly species, Chrysomya putoria (Diptera: Calliphoridae) on Ricinus communis (Euphorbiaceae) in Sudano-Sahelian area of Cameroon in 2017 and 2018. To do so, castor bean plants were flagged and fly foraging parameters were recorded. The effects of blowfly activity on pollination and fruiting rate of R. communis were estimated by comparing unrestricted and...

Spatial and temporal variability of soil micronutrients and their relationships with wheat (Triticum aestivum L.) yield and some major soil variables

Studying the spatial and temporal variability of soil micronutrients and their effects on plant growth is important for implementing precision-farming and/or economizing fertilizer management. The present investigation was done through soil sampling (0–20 cm depth) from three locations in central Ethiopia. The tools employed include, descriptive and/or classical statistics. The concentrations of available copper...

Stability of productivity parameters of six cocoa clones [Theobroma cacao (Malvaceae)] during the main production season in Côte d'Ivoire

The strong climatic fluctuation observed during the major cocoa production period with reductions in rainfall and rising temperatures lead to a low graining index. This climatic situation makes cocoa marketing difficult for producers. The stability of quantitative productivity parameters in six cacao clones on farm was analyzed during the main production season. Flowering, average pod weight, number of beans per pod,...

Maize intercropped between Eucalyptus urophylla in agroforestry systems in Brazil

The objective of this work was to evaluate the agronomic characteristics of maize intercropping with Eucalyptus urophylla at agroforestry system in two triple row distance (alleys) at different sampling distances and positions in relation to the eucalyptus external row (transect), and three positions in relation to the cardinal points: east side, west side and middle. Eucalyptus (E. urophylla) seedlings were planted...

Pre-harvest Loss Assessment of Maize crop in Semi-arid Areas in Tanzania Due to Rodent pests

Two experiments were conducted, first was to estimate maize seedling damage in farmers’ fields and a simulation experiment. This study aim to investigate the impact of rodent pest species, damage to maize crop in semi-arid areas at pre-harvest, with a view to provide farmers with appropriate information on rodent pest management interventions. In farmers’ fields, damage assessment was done by counting the...

Comparison of the infestation of three rubber tree clones by Phragmantera capitata (Sprengel) S. Balle (Loranthaceae) in the South-west region of Cameroon

Rubber tree clones are used for their high latex production, resistance to the diseases and to the climatic conditions. The aim of this study was to characterize the parasitism of Phragmanthera capitata on three rubber clones. The study was carried out in the rubber plantations of the Cameroon Development Corporation located in 4 villages around Muyuka and Tiko, two locality of the Fako Department, South-West Region of...

Research achievements and recommendations in crop management for enhancing the productivity of spices: A review

Spices are invaluable crops in Ethiopia and research. Just like coffee, their production started many years ago. Availability of diverse agro ecology allowed the country to cultivate different spices. Lowland (ginger, turmeric, black pepper, cardamom, and vanilla) and highland seed spices (black cumin and white cumin, fenugreek, and coriander) were some of the target in research. Appropriate crop management practices,...

Dominant practices, information, and constraints of soil moisture conservation and nutrient management for range pastures in a sedentary grazing system in South-Western Uganda

Range pastures constitute the major source of livestock feeds throughout the year in the grazing areas of Uganda. However, pasture yields have been declining overtime, yet there is limited information on efforts of improving pasture productivity through soil moisture conservation and nutrient management. This study assessed soil moisture conservation and nutrient management practices used by livestock farmers, sources...

Experimental study on the effect of light quality on the quality of hydroponic Cichorium endivia L. in plant factory with artificial light

In recent years, plant factories have developed rapidly and played an important role in modern agricultural production. Finding the best lighting formula has become the most basic and important research topic for the industrialization of the plant factory with artificial lighting (PFAL) hydroponic Cichorium endivia L. In this paper, the LED plant growth lamp with adjustable ratio of red, blue and white light intensity...

Analysis of the determinants of adoption of bio-herbicide technology for sustainable food production in the North-Eastern Region of Nigeria

There is a growing concern in many developing countries of sub-Saharan Africa on the harmful effects of synthetic herbicide usage on the agro-ecology, as well as food crop production. Therefore, this study focused on analyzing the factors that influence the adoption of bio-herbicide technology as an alternative to the chemical herbicides used by rural farmers in the North-Eastern region of Nigeria. Multi-stage random...
