Major Research & Development Focus Areas
Rice-the staple food-general information
Major Research & Development Focus Areas
Development of new rice varieties which
- could withstand climate change & its impacts
- are resistant to prevailing and emerging pests and diseases
- are high yielding
- having sensory qualities (aroma & taste) attractive to consumers
- having improved nutritional qualities & healthy
- could withstand negative environmental quality (soil, air & water)
- could resist yeild damages possibly arise from agrochemicals
- are fertilizer and agrochemical efficient
- are weed competitive
- etc.
Looking forward for mechanisms which could lead efficient use of seed paddy through:
- reduced rates of seed paddy per land area
- efficient seed treatments for disease management
- finding ways to make seed paddy abundantly available
- efficient agronomic practices
- etc.
Understanding the ways to maimize utilization of crop seasons, and inter-seasonal time periods through:
- opportunities for additional cultivation seasons
- possibilities of cultivating without strict concerns on a seasonal bounds
- ways to cultivate with reduced and efficient water supply
- understanding pest dynamics and their efficient management
Land preperation is a key step that could lead to a successful crop. Efficient and optimized land preperation methods will be evaluated with
- possible maximized mechanization
- methods to manage pest life stages in soil
- minimized water use for land preperation
- feasible, economical and easy levelling methods
- etc.
Research will be ficussed on
- optimized plant density in the field that supports higher yeilds, and low pest damages
- methods that could minimize labour cost
- mechanized crop establishment methods
- etc.
Exploring possibilities on
- precision nutrient application management
- optimized practices for organic farming
- pest management through nutrient application management
- improvement of plants response to nutrients
- optimized practices for soil amendments
- mechanization/automated application methods
- etc.
Projected research areas would be
- improving plants’ response to water
- improving efficincy of water uptake by plants in water stress situations
- re-use of used water
- management of water quality (both in-flow and out-flow)
- minimized requirements for water
- optimized integrated management methods for each pest
- integrated methods that could manage pest community in a field
- reduction of agrochemical use through precision application
- pest predictions and early warning
- emergency response readiness
- adjusted environmental conditions that could support crop to withstand pest damages
- adjusted abiotic and biotic environment that demotivates pest survival
- biocontrol methods and natural herbicides
- identifying and surveying weed species in major rice growing areas, including emerging weeds
- understanding external factors that could influence non weedy species or opportunistic species to become a weed and management of such conditions
- mapping weed populations and communities
- precision weed management methods
- targeted application of herbicides to achieve reduced pesticide use
- evolutionary patterns of weed species, populations, and communities
- co-existence of species (plant-plant and plant pest/disease)
- patterns of hybridization
- how the weed species develop vigor and resist/ tolerate agrochemicals
- identify and understand true weeds
- adjustment of environmental factors to unfavour weed establishment, growth and spread
- Understanding soil seed bank ecology and their management
Post harvest quality of the produce should be managed in long run, as harvest is released sequentially based on the market demand.
- developing standards for long term storage facilities
- mechanisms to maintain quality in stored paddy
- dehulling quality, and sorting
- optimum drying conditions and methods
- packing, packaging and treatments for pests and diseases
- popularization, reaching niche markets and international markets
- value addition
- parboiling and drying, improved methods to retain quality and mechanization
- production data management
Global climatic changes could impose negative or positive impacts on food production and the productivity. In addition, some environmental changes may have mutual impacts on other environmental factors. Research targetted to address these issues may be:
- identifying genotypes that are tolerent to / could withstand stresses
- introduced stress escape mechanisms to plants
- identifying plant physiological processes that improve plants' ability of efficient resource use, photosysnthetic efficiency, and generate higher yields
- readiness for emerging abiotic stresses
Chemicals and mechanical devices that are environmentally friendly, health safe, economical and easy to use, could be locally deveveloped for farmer use.
- development of eco friendly, pesticides/ herbicides
- herbicides and pesticides specifically targetted for certain species
- precision applicators
- equipment and machinery that could reduce labour cost at each stage of cultivation
- etc
