A review on postharvest handling of avocado fruit

This paper reviews the literature on the effect of pre- and postharvest treatment effects on the postharvest quality of avocado fruit. It is evident from literature that pre-harvest factors such as ambient field temperature and water stress affects the postharvest physiology of avocado fruit. The postharvest handling treatments and environmental conditions identified were pre-packaging treatments, different density...

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...

Effects of soil moisture conditions on vegetative reconstruction with alfalfa on the northern Shaanxi Loess Plateau

Vegetative reconstruction using alfalfa (Medicago sativa) has been effective in many areas to combat desertification. In arid regions of the China Loess Plateau water availability limits alfalfa productivity. Precipitation, runoff, soil moisture, and alfalfa biomass data from 2008 to 2010 on four distinct slopes representative of the Northern Shaanxi Loess Region, were collected. Relationships between precipitation,...

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...
