Treatments and utilization of swine waste in Brazil

Swine wastes obtained from farming activities have the greatest impact on the environment by environmental agencies. Swine wastes together with poor management represent risks to the environment. In Brazil, these activities significantly increased in the last years and from 2014, the country became the fourth largest producer in the world. Swine wastes are generated in high amounts due to the confinement system used...

Effects of edible coating materials and stages of maturity at harvest on storage life and quality of tomato (Lycopersicon Esculentum Mill.) fruits

Tomato (Lycopersicon esculentum Mill.) fruits due to their high moisture content are spoiled and deteriorate in short period of time. Once fruits are harvested, respiration and transpiration are the two major physiological processes that significantly affect storage life and quality of the fruits. However, effects of these processes can be minimized through optimizing harvesting stage of fruits and applying physical...

Wheat yield obtained from nitrogen dose and fractionation

It is possible to increase nitrogen for wheat productivity by adjusting the single and fractionated dose based on the condition of the agricultural year. The objective of this work is to study the  highest  amount of nitrogen used for the production of wheat using single dose  or fractionation under favorable and unfavorable cultivation years. The study was conducted in  2012, 2013 and 2014 in...

Effect of Global-GAP policy on smallholder French beans farmers’ climate change adaptation strategies in Kenya

This study analyzed the role of Global-GAP policy, on smallholder French beans farmers’ climate change adaptation strategies in, fruit and vegetables farming. It considered: (1) the prevailing adaptation strategies used by the farmers; (2) regional differences in the farmers’ adaptation strategies; and (3) how Global-GAP policy influence the farmers’ decisions on the use of adaptation strategies. A...

Adjustment of decay rates of organic matter in a Latossolo Vermelho-Amarelo in the Araripe National Forest, Brazil

The use of mathematical models is an alternative way to understand how management practices affect soil organic matter (SOM) dynamics because such models yield results on time scales that would be impossible to observe in field studies. The aim of this study was to parameterise and calibrate the application Century 4.0 in terms of the edaphoclimatic conditions of a Latossolo Vermelho-Amarelo of the Araripe Plateau and...

Aluminum buffering in acid soil under mineral gypsum application

Many researches have performed on gypsum application to correct high exchangeable aluminum content in acidic soils, especially in subsurface. Although, they have found increases in the exchangeable calcium and sulfur contents, exchangeable aluminum has not been decreased. The exchangeable aluminum buffering by organic matter may contribute to non-significant reduction in exchangeable acidity. The objective of this study...

Soil pH, available P of an ultisol and castor performance as influenced by contrasting tillage methods and wood ash

The effect of tillage methods and rates of wood ash on soil chemical properties and castor bean plant performance was studied in field trial at Abakaliki in three planting seasons. The experiment was a split plot in randomized complete block design with three tillage methods (mound, ridge, flat) and four rates of wood ash (0, 2t, 4 and 6 tha-1) replicated three times. Crop start version 7.2 was used to analyze data...

Socioeconomic determinants of hybrid maize adoption in Kenya

Kenya has increasingly relied on modern agricultural technology to increase productivity since land extensification is no longer a feasible option to satisfy national food demands. Hybrid maize varieties have been one of the more successful technologies developed, responsible for dramatic yield increases in the developed world since World War II and more recently as an integral part of the Green Revolution. The purpose...

Assessing environmental and social impacts of the oil palm industry in Ghana: A project synthesis

The oil palm industry has many positive benefits, particularly as a key source of livelihoods for rural dwellers, but it also has negative impacts on the society and environment. For instance, poorly planned oil palm cultivation can increase the rate of natural forest loss, and contribute to unfair labour conditions on plantations and processing mills. It is therefore important for sustainable oil palm project...

Challenges of herdsmen-farmers’ conflict in livestock production in Nigeria: Experience of pastoralists in Kogi State, Nigeria

Herders-farmers’ conflict is wide spread and a formidable challenge to livestock production in Nigeria. The study examined challenges faced by pastoralists in conflict with farming communities. A total of 72 Fulani pastoralists from transit camps were used. Data were collected by use of structured interview schedule, focus group discussion and personal observation and analysed using descriptive statistics and...

Viability of the use of grass in the cultivation of the medicinal mushroom Ganoderma lucidum

The objective of this work was to evaluate the use of ten types of grasses as base substrate for the cultivation of strain GLM-10/02 of Ganoderma lucidum, considering the chemical characterization of the substrates, the biological efficiency (BE), the quantification of fresh and dry basidiomata and the number of basidiomata as evaluation criteria. Ten treatments were outlined, made up with napier or elephant grass...

Does the quality of Luehea divaricata seedlings in the nursery correspond to their behavior in the field?

The species, Luehea divaricata offers great ecological and timber potential in addition to a wide geographic distribution, although there are few studies comparing seedling production in the nursery with its development in the field. Therefore, this research aimed to evaluate the performance of L. divaricata seedlings produced in different substrates in the nursery, as well as verify if the results obtained influence...
