Participatory seed production of small millets among tribal farmers of Bastar region, Chhattisgarh, India

Small millets could be better option under vagaries of rainfall and dry situation of the region when rice and other crops get failed regularly because it tolerates water stress, drought and erosion. Plenty of lands were available as upland in this region which might be converted in small millets production by participation of farmer in seed production programme for uplifting economic of farmers. Ten clusters were formed...

An evaluation in vitro and in vivo of rhizobacteria in the biocontrol of Radopholus similis in banana

Rhizobacteria were isolated from the rhizosphere of banana cultivars ‘Prata Comum’ and ‘Prata Anã’ and from crotalaria and marigold in Tryptic Soy Agar and King B-agar media. Bacteria were used for valuations of the in vitro and in vivo. The promising isolates were submitted to identification by polymerase chain reaction. Among the one hundred and fifty two evaluated, twenty three showed...

Carcass and non-carcass characteristics of sheep fed with açaí seed meal-based diet

The byproducts of agricultural processes have great potential as a source of low cost animal feed. In this paper we assess the potential of açaí palm (Euterpe oleracea Mart.) seed as a food source for sheep. Sixteen non-castrated male sheep with average initial body weight of 22 kg were randomly assigned to one of four diet treatments, using initial body weight as a covariate. The diets consisted of...

Genetic progress in seed yield of physic nut (Jatropha curcas L.)

Physic nut (Jatropha curcas L.), a tropical shrub with medicinal properties has not undergone efficient selection for high seed yield or oil production over the years. Predictions on seed yield of this oilseed plant were based on isolated observations that did not consider the reductions in plant growth due to higher planting densities. The objective of this study was to quantify the genetic progress of seed yield using...

Storage profitability and effectiveness of storage methods in yield loss reduction in cocoyam in southeast Nigeria

Cocoyam is highly perishable and considerable economic losses can occur after it is harvested due to rot, sprouting and other physiological changes. This perspective hinges on the economic study of cocoyam storage in south-east Nigeria. The study was guided by null hypothesis that the mean cocoyam rot of the six storage methods did not significantly differ and that the mean income of the six storage methods did not...

Effectiveness and persistence of biological control of nematodes in sugarcane

The objective this study was to investigate the effect of use of Bacillus subtilis to control nematodes, considering the hypothesis that the efficacy and persistence of biological control is equivalent to chemical control with respect to the community of Meloidogyne spp. and Pratylenchus zeae in soil during the growth of sugarcane (Saccharum spp.). For this study, soil was collected from cultivated area of sugarcane...

Spatial variability of physical attributes of cambisol under cassava cultivation in Southern Amazonas

The aim of this research was to evaluate the spatial variability of soil properties of a haplic cambisol under cassava cultivation in Humaitá County, AM - Brazil. The mapping of a cassava growing area was made and a 70 × 70 m square mesh designed. In the mesh, soil samples were performed in a regular spacing of 10 m at a 0.0 to 0.2 m depth, being a total of 64 sample points. Physical analyses were made...

Hydrogeochemical assessment of groundwater quality in the Baya watershed (Eastern of Côte d’Ivoire)

The large demand for drinking water in the Baya watershed (6324 km2), located in East of Côte d’Ivoire is supplied from groundwater sources. This study investigated the specifics hydrogeochemical assessment of groundwater quality in the Baya’s watershed by using statistical methods with graphical and self-organizing maps (SOM) neural network methods. It was carried out to identify the hydrogeochemical...

Effect of the seasonal climatic variations on the composition and quality of “Chemlali” virgin olive oil

“Chemlali” is the main olive variety cultivated in Tunisia. Seasonal factors such as rainfall and temperature vary year to year influencing the composition and quality of virgin olive oil. This work aims to investigate the effect of the seasonal climatic variations on the quantity and the quality characteristics (free acidity, specific ultraviolet absorbance K232 and K270, fatty acid composition,...

Effect of water deficit on carbon metabolism in Spondia mombin L. plants

In Brazil, hog plum trees are found mainly in the North and Northeast regions; they are considered to be under plant domestication and extractive exploitation. Therefore, it is economically important for those regions. In order to evaluate physiological and biochemical aspects of carbon metabolism in young hog plum plants (Spondia mombin L.) under full irrigation and water deficit conditions, an experiment was conducted...

Designing factories for nematode-based biological control products for an alternative, environmentally friendly management of soil insect pests

Soil insects are a major source of crop loss in tropical, subtropical and temperate zones. Many soil insecticides are either/or highly toxic to humans, have serious other non-target effects, or are a banned from use nationally or internationally. An alternative strategy is the use of beneficial (entomopathogenic) nematodes as they are well-adapted to the soil environment and non-toxic. However, the establishment of...

Ant diversity in agro ecosystems and secondary forest

The knowledge of ant diversity in an area can provide important information to set up management and conservation planning. This study aimed to identify the ants colonizing cultivated areas comparing their composition, abundance and diversity with the myrmecofauna from a non-managed area. The research was carried out at the Farm School at the Maranhão State University in São Luis, Northeastern Brazil from...

Evaluation and comparison of soil under integrated crop‐livestock-forest system in the southeast of Goiás, Brazil

The integrated crop-livestock-forest (ICLF) has been indicated as an important alternative of agricultural production, in economic and environmental terms. This study aimed to evaluate and compare the chemical properties of soil under the system on integrated crop-livestock-forest in the Santa Brígida Farm, Ipameri City, southeast of Goiás State, Brazil. It was used a completely randomized design in a 4...

Isolation and selection of P-solubilizing and IAA-synthesizing microorganisms from the rhizosphere of Guanandi (Calophyllum brasiliensis)

Phosphate solubilization by microorganisms is an important process for increasing the bioavailability of phosphorus (P) to plants. This study aimed to: (a) in solid medium, isolate CaHPO4-solubilizing and non-P-solubilizing microorganisms from the rhizosphere of guanandi (Calophyllum brasiliensis) collected from a nursery and the field; (b) in liquid media, quantify the ability of CaHPO4-solubilizing isolates from the...

Energy metabolism and digestive enzymes of Sitophilus zeamais exposed to an insecticide

The maize weevil Sitophilus zeamais is a primary pest of stored grains, and it is primarily controlled through the use of synthetic insecticides, which are directly connected to increases in the resistance of these insects. In this study, populations of S. zeamais acquired from small farmers in southern Piauí were obtained, and an experiment was performed with the insecticide K-Obiol EC25, with dose-response...
