Biochar an alternate option for crop residues and solid waste disposal and climate change mitigation
Atmospheric rise of CO2, N2O and CH4 over years, accelerated increase in global temperature, has led to uncertainty in monsoon rainfall and also leading to recurrence of drought, which in turn is severely affecting crop productivity and livelihood security of the farmers in Semi Arid Tropics. Agriculture contributes considerable amount of CO2, N2O and CH4 emission into the atmosphere through different soil and...

Mineral nutrition in the control of nematodes
Although plant tolerance and resistance to pathogens are genetically controlled, they are significantly influenced by environmental nutrition factors. Mineral nutrients can increase or decrease resistance or tolerance to pathogens and pests. Plants receiving ample nutrition have higher resistance to diseases and higher tolerance. This is based on the fact that more vigorous plants have greater capacity to offset a loss...

Phytotherapy in the control of helminthiasis in animal production
Parasitic diseases constitute one of the main problems affecting livestock; however the use of chemical medicaments provides drug resistance residues in animal and environmental contamination. Changes in production concepts require that food must be produced in hygienic conditions, per healthy animals and that are not eliminating antibiotic residues, pesticides or other drugs. This scenario has favored organic...

Fuel-wood energy properties of Prosopis juliflora and Prosopis pallida grown in Baringo District, Kenya
Kenya depends on fuel-wood for cooking and heating in most households. Over 80% of both rural and urban households in the country use fuel wood for cooking. These Prosopis plant species provide excellent fuel wood. These plants were introduced in the arid and semi-arid areas of Kenya in the early 1970s as a source of woodfuel and also for the rehabilitation of degraded lands. Prosopis is a prolific seeder and...
