Farmers in Africa have not been fully convinced to invest in fertilizer due to uncertainty on returns to investment. This is despite the fact that, more than two-thirds of people in Sub-Saharan Africa rely on agriculture for employment with many living on small farms earning less than $1 per day. Usage of fertilizer has remained low and stagnant hence the yields in have been persistently lower than other parts of... Read more.

In Uganda and elsewhere in the world, tomato is an economically important vegetable and a good source of vitamins A and C. Being an important horticultural crop, its production is threatened by root-knot nematode infections that make plants susceptible to wilting, growth reduction and infection by other pathogens like bacteria and fungi. Identifying the root-knot nematode species on the crop is paramount in designing... Read more.

Family agriculture is a rich germplasm source wherever it takes place; however, information on genetic variability of this type of culture in Brazil is scarce. Samples of melon (Cucumis melo L.) accessions grown by family agriculture were rescued and this study aimed at characterizing the genetic variability in one sample of these accessions so as to identify the melon subspecies and the corresponding varieties. Fifteen... Read more.

The experiment assessed the proximate and amino acid compositions, metabolizable energy and anti-nutrient constituents of Tithonia diversifolia leaf meal (TDLM) harvested separately in the months of May and September, respectively using standard laboratory methods. The crude protein (20.5±0.1%), crude fibre (18.8±0.01%) and ash (14±0.1%) significantly (p˂0.05) increased in TDLM for September cutting... Read more.

Every month, about 40 tons of waste prunings of trees and grasses are wasted in Bauru, São Paulo, Brazil, occupying unimaginable volumes in the municipal landfill. This rich material has been tested for cultivation of medicinal mushroom Ganoderma lucidum, rather unknown in Brazil, compared to commonly use eucalyptus sawdust. Thus, the objective of this study was to evaluate the use of wasted urban vegetable... Read more.

The use of yield-level management zones (MZs) has demonstrated high potential for site-specific management of crop inputs in traditional row crops. Two approaches were use: all variables approach (all_Var) and stable variables approach (sta_Var). In each approach, variables selected had significant correlation with yield, while all redundant and non-autocorrelated variables were discarded. Two fields were use in this... Read more.

Crambe (Crambe abyssinica Hoschst) is a winter oilseed crop with yield potential of 1500 kg ha-1. It is indicated for crop rotation systems and tolerates moderate frost. However, crambe presents thermal and water limitations that influence sowing dates since it needs water at blooming and at least 200 mm rainfall until it reaches the flowering stage. This study aimed to assess the performance of a crambe crop in... Read more.

Several legumes have natural ability to associate with nitrogen-fixing bacteria known as rhizobia. The efficiency of this association depends on the plant and bacterial genotype and the edaphoclimatic conditions. Peanut is a tropical legume able to associate with a wide range of rhizobia and the selection of efficient bacteria is important to increase the nitrogen fixation in this crop. In order to investigate the... Read more.
