Conservation agriculture for small holder rainfed farming: Opportunities and constraints of new mechanized seeding systems
Small holder farmers in rainfed agriculture believe that soil tillage is needed to maximize crop yields. However, as cropping intensity, and hence tillage intensity, increases there may be a decline in particular physical, ...
Conservation agriculture and soil carbon sequestration: between myth and farmer reality
Improving food security, environmental preservation and enhancing livelihood should be the main targets of the innovators of today's farming systems. Conservation agriculture (CA), based on minimum tillage, crop residue ...
NDVI as a potential tool for predicting biomass, plant nitrogen content and growth in wheat genotypes subjected to different water and nitrogen conditions
The application of spectroradiometric index such as the normalized difference vegetation index (NDVI) to assess green biomass or nitrogen (N) content has focused on the plant canopy in precision agriculture or breeding ...
Conservation agriculture for wheat-based cropping systems under gravity irrigation: increasing resilience through improved soil quality
A field experiment was conducted under furrow irrigation on a Vertisol in arid northwestern Mexico, to evaluate sustainable production alternatives for irrigated wheat systems. Treatments included: tillage (conventionally ...
Ensuring the use of sustainable crop management strategies by small wheat farmers in the 21st century
Virtually all current strategies to implement modern, sustainable crop management production practices involve conservation/zero tillage prior to seeding, some form of crop residue retention and management, fertilizer ...
Developing aerobic rice cultivars for water-short irrigated and drought-prone rainfed areas in the tropics
Aerobic rice is a production system in which rice is direct seeded and grown in nonpuddled and nonflooded aerobic soils. Aerobic rice varieties need to be developed to cope with the increasing water scarcity in tropical ...
