Use of aniline blue stain to observing pollen tubes development in different Manihot Mill. species
The lack of a reliable test to evaluate pollen viability in species of the genus Manihot is one of the primary limitations for cassava genetic improvement. Thus, the objective of the present study was to apply aniline blue stain to observing pollen tubes development in different Manihot Mill. species, in order to estimate the crossability, pollen germination time, pollen tube size and pollen longevity. Pollen grains...

Minimally processed prickly pear stored under different temperatures and packaging
The desirability of minimally processed products makes the prickly pear (Opuntia ficus indica (L.) Mill) an option for this market. The aim of this work was to verify the effects of storage temperatures and packaging on the conservation of minimally processed prickly pear. Ripe fruits with greenish exterior were used, and after peeling and sanitization were placed into one of the following storage methods: (1)...

Effects of different agricultural land use types on physical properties under rainforest agroecology
The study was conducted at the Teaching and Research Farm, Obafemi Awolowo University Ile-Ife which approximately lies on latitude 7° 28ʹN and longitude 4° 33ʹ E with an altitude of about 244 m above the sea level. Different agricultural land uses examined were: Secondary forest, planted fallow with legumes, Bush fallow (Cromolaena odoratum), Continuous cassava/cowpea plot (Manihot esculenta-Vigna unguiculata...

Nitrogen and potassium concentration in the nutrients solution for the production of tomato (Solanum lycopersicum)
This study viewed to determine the effects of N and K concentrations in the nutrients solution on the productivity and fruit quality of tomato plants growing in a hydroponic medium. The experiment was carried out from January through April of 2011, in Jaboticabal, São Paulo, Brazil. The experiment was divided in two phases – the first took place during the vegetative development of the plants and it...

The operation of mechanical sugarcane harvesters and the competence of operators: an ergonomic approach
The mechanisation of sugarcane harvesting in Brazil has experienced significant growth. Mechanical sugarcane harvesters have been rapidly improving to meet the demands of the industry. Operating a harvester machine requires knowledge and competence. This article aims to demonstrate the role of the operator competence in carrying out their task and in the quality of their performance. By applying the Ergonomic Work...

Soil phosphorus availability and dry bean yield as affected by the application of liquid calcium carbonate micron particles on the furrow
The application of calcium carbonate micron particles in the planting furrow, because of the reduced particle size may favor a faster reaction in the soil and could provide increased pH and P availability for plants such as dry bean (Phaseolus vulgaris L.), potentially increasing yield. A field experiment was conducted for two consecutive years with the objective to evaluate the effect of the liquid calcium carbonate...

Effect of climate change resilience strategies on productivity of common bean (Phaseolus vulgaris L.) in Semi-arid areas of eastern Hararghe, Ethiopia
Climate change has an impact on the common bean productivity and its negative effect has to be mitigated using alternative resilience strategies. Field experiments were conducted in 2012 and 2013 cropping seasons at Babile and Haramaya research stations, eastern Ethiopia, to assess the effects of climate change resilience strategies on yield and yield components of common bean. The results of the study revealed that row...
