Sustainable intensifications of African agriculture through legume-based cropping and Brachiaria forage systems

Legume-based cropping system and Brachiaria forage system could play a significant role in enhancing food and nutrition security and sustainable intensifications of African agriculture. To reveal this potential, a comprehensive review of literatures and assessment was performed using key indicators in relation to food and nutrition quality, agro-ecological services and socioeconomic benefits. The key indicators for...

Effect of silver nitrate on shoot multiplication, rooting induction and plantlet characteristics of St. John’s wort (Hypericum perforatum L.) in vitro culture

St. John’s wort (Hypericum perforatum L.) is one of the introduced medicinal plants that have medicinal uses for anti-depressant. Germplasm conservation of St. John’s wort has been conducted at the laboratory for over ten years and plantlets showed a rosette growth. Therefore, laboratory investigations are necessary to be done to have better methods for obtaining normal growth of culture. In this study, we...

Screening of rice germplasms under salt stress by phenotypic and molecular markers

The evaluation of salinity tolerance of rice germplasms based on phenotype and genotype of 100 rice germplasm was identified at the seedling stage at the High Agricultural Technology Research Institute for Mekong Delta, Vietnam. Screening of the phenotype was done with 30 day old seedlings using salinized concentrations (EC = 8 and 15 dS/m). Results show that the growth of the varieties, the higher the salt...

Thermal comfort estimation for dairy cows in the south of Goiás State, Brazil

The objective of this research was to analyze the correlation between climatic and milk composition variables. Thus, meteorological data and data on milk quality and composition (fat, protein, lactose, total solids content and defatted dry extract (DDE)) were used, as well as somatic cell count (SCC). The analysis was performed using the Pearson correlation test. After the study, it was verified that the temperature...

Effects of NPK and plant tea manure (Tithonia diversifolia) on growth rate of amaranth (Amaranthus cruentus L.) in soilless growing media

Many countries are running short of agricultural land. Even where land appears to be available, soil fertility, water availability as well as nutrient mining still remains a challenge yet at the same time the world’s demand for food is rapidly increasing. Millions of square meters of soil are mined each year for use in vegetable nurseries and in backyard gardens in addition to excessive use of inorganic...

Drought tolerance assessment of melon germplasm searching for adaptation to climate change

Shortage of irrigation water at critical melon growth stages can be the most important limiting factor in the future due to climate change, especially in the Mediterranean region. Apart from the improvement of irrigation systems and crop management, the development of drought tolerant cultivars by genetic breeding is the best solution to achieve stable yields. Screening germplasm collections is a prerequisite for that....
