Viability and enzyme activity of coffee seeds subjected to LERCAFE test
The LERCAFE test consists in immersing coffee seeds in an active chlorine solution, which reacts with the seeds’ endosperm, thus staining the viable parts dark green. The goal was to adapt the LERCAFE methodology to coffee seeds and assess the isoenzymatic profile of seeds subjected to the test. Two experiments were conducted, the first with adequacy of the LERCAFE test methodology, and the second experiment...

Morpho-biochemical responses to salinity tolerance in common bean (Phaseolus vulgaris L.).
The effect of salinity stress during germination, early seedling and vegetative growth on morphological and biochemical traits was evaluated for 18 genotypes of common bean (Phaseolus vulgaris L.) at 0, 60, 120, and 180 mM NaCl. Analysis of variance showed that the salinity stress had significant effect on all traits except shoot to root length and dry weight ratios. Though salinity stress delayed germination in all...

Physiological quality of quinoa seeds submitted to different storage conditions
Quinoa has grown importance in the world due to the nutritional quality of its grains and crop adaptability to diverse climatic conditions. One problem that limits its cultivation is the reduced viability of seeds during storage and the information is rather scarce. This work aimed at evaluating the physiological quality of quinoa seeds along time when submitted at storage conditions and packaging. An entirely...

Soil physical and hydraulic changes in different yielding zones under no-tillage in Brazil
Soil physical and structural degradation may influence crop productivity over time in long-term no-tillage system areas. A field study was conducted at two sites, Palmeira das Missões and Não-Me-Toque, in southern Brazil to quantify soil physical/hydraulic and structural changes in zones with different yield potentials. The sites have been managed under no-tillage system without soil disturbance for more...

Volumetric models for Eucalyptus grandis x urophylla in a crop-livestock-forest integration (CLFI) system in the Brazilian cerrado
The influence of the forest component in the crop-livestock-forest integration system depends on several factors, among which are the plant species used and the row spacing established in system deployment. Therefore, the objective of this study was to characterize the tree component dendrometrically using Eucalyptus grandis x urograndis individuals from the CLFI system and to determine the model fit with volumetric...

Physicochemical quality of Murici covered with starch-based coverings and stored at different temperatures
The aim of this work was to evaluate the physicochemical characteristics of murici (Byrsonima crassifolia (L.) Rich.) covered with starch-based coverings and stored at different temperatures. The fruits were harvested on EMBRAPA experimental farm, in the city of Pacajus-Ceará, where they were taken to the lab, washed, sanitized and naturally dried. Afterwards, they were treated with coverings made out of...

Evaluation of Spirulina platensis as microbial inoculants to enhanced protein levels in Amaranthus gangeticus
The demand for increase in food production for increasing population with adequate bioavailable nutrients has become a challenge for the agriculturists, nutritionists, biotechnologists to meet the requirements of mankind. The microbial biofertilizers are applied in the form of seaweed liquid extracts, microbial inoculants, biostimulators and biofortification agents. All these categories of microbial biofertilizers are...

Farmers’ adaptive measures to climate change induced natural shocks through past climate experiences in the Mekong River Delta, Vietnam
This study examined farmers’ adaptive measures to climate change induced natural shocks through past climate experiences in the Mekong River Delta (Vietnam) from a data set of 330 farmers. Seemingly unrelated regression model was used to identify the determinants of farmers’ adaptive measures. Results showed that male household head, education of the household head, marital status of the household head,...

Effect of different irrigation levels with different qualities of water and organic substrates on cultivation of pepper
The amount of water needed to meet the water requirement of crops and use of alternative organic substrates affect the development of the plants’ nutrients. The objective of this research is to evaluate the cultivation of pepper (Capsicum chinense) under different organic substrates and irrigation levels with supply water and wastewater. The experiment was conducted in a greenhouse at Campina Grande,...

Clustering analysis of several peanut varieties by pre and post-harvest and biochemistry parameters
Peanut (Arachis species) plants originated in South America where they have existed for thousands of years. Successively, peanut culture has been introduced in many African countries and was incorporated into local traditional food cultures. Numerous studies showed peanut nutritive importance and capacity to prevent several human diseases. The target of the present survey aimed to create a germplasm benchmark of peanut...

Effect of scab disease on the yield of intercrop systems of cowpea maize and sorghum
Three field sites were selected during the raining season (July to October) of 2004, 2005 and 2006 at the Institute for Agricultural Research, Ahmadu Bello University, in Samaru, Zaria, Nigeria to determine the effect of scab on the yield of cowpea variety (Ife brown) intercrop with cereals. This variety (Ife Brown) selected was highly susceptible to scab. Any reduction in yield is attributed to the disease since it...
