An alternative to complete banana mat uprooting: Assessing the effectiveness of continuous cutting at soil level of all shoots in a mat on speed for corm decay

The complete uprooting of diseased mats/fields (CMU) is one of the recommended control options for Xanthomonas wilt of banana. CMU is labour intensive, time consuming and disturbs the soil structure, exposing fields to erosion. CMU often involves exportation of whole plant biomass, affecting soil fertility. The potential of continuous cutting at soil level of all shoots in a mat until complete corm decay in situ as an...

The effects of crop rotation systems on maize agronomic traits under no-tillage in optimal and dry cropping seasons

The purpose of this research was to evaluate the crop rotations effects on agronomic traits of maize cultivated in spring-summer in optimal (OCS) and dry cropping seasons (DCS). The experimental design was set up in a randomized complete block and the treatments were arranged in a factorial (8 x 2), consisting of 8 crop rotation systems and two cropping seasons (OCS and DCS), with four replications. The following...

Chemical attributes of the soil in agroforestry systems subjected to organic fertilizations

The reuse of organic byproducts in agroforestry systems is a sustainable proposal, since, in addition to preserving the natural resources, it has allowed the fertilization of the soils, obtaining a reduction of costs with mineral fertilizers. Therefore, the objective of this research was to evaluate the chemical attributes of the soil after two years of successive fertilizations using cattle manure and sewage sludge in...

Impact of climate change on the incidences of small ruminant diseases in a pastoral area of Kenya

Participatory epidemiological methods were used to establish local perceptions and livestock owner’s knowledge, attitudes and practices (KAPs) of risk factors that impacts of climate variability and the seasonal variations in incidences of livestock diseases, disease vectors, intermediate hosts and rainfall in pastoral Rift valley of Kenya. The interaction of the molecular biology of the pathogen itself; vectors...

A case study on compensatory growth of emaciated cattle fed on total mixed ration

A study was conducted in Thailand with the aim of evaluating compensatory growth of emaciated cattle fed on ad libitum total mixed rations (TMR) under smallholder feedlot management. Two farms were identified where 121 cattle of various degrees of emaciation were bought for fattening trial. Cattle were grouped according to the degree of emaciation within respective pens and were fed on same type of feed throughout the...

Harvest time, stem and grain sensibility of maize hybrids with contrasting growth cycles

The delay of maize harvest may affect the stem and grain sanity. This work was carried out aiming to evaluate the effects of harvest time on the incidence of stem rots and rotten grains of maize hybrids with contrasting growth cycles. The experiment was set in Lages, SC, during the 2012/2013 and 2013/2014 growing seasons. A randomized block design, disposed in split plots was used. Five single-cross hybrids were tested...

Interaction of genotype, environment and processing in the chemical composition expression and sensorial quality of Arabica coffee

The present study was carried out to analyze chemical descriptors present in the raw coffee bean and to establish an association of these descriptors with the sensorial quality of the coffee beverage, based on expressions resulting from the interactions of coffee genotype, environment, and processing. The chemical descriptors caffeine, trigonelline, sucrose, and isomers of chlorogenic acid (3-CQA, 4-CQA, and...

Irrigation depths in sugarcane crop with drip irrigation system

This study aims to evaluate the growth and development of sugarcane under different supplemental irrigation depths. Irrigation treatments were 0.30, 0.60, 0.90 and 1.2 rate of crop evapotranspiration (ETc) and the control (no irrigation). The experimental design was a randomized complete block with six replications. The highest yield was ratoon cane with 190 t ha-1 in the treatment 0.6 of ETc. The difference between the...
