Establishing highly productive paddy field farming

We are promoting the development of a lowland crop rotation system, through breeding rice, wheat and soybean cultivars, consolidating rice cultivation management with low-input and high-efficiency, developing soil management and pest control system for sustainable agriculture, utilizing forage rice through field and livestock farming, and developing system with high-quality, low-cost cultivation techniques.

Breeding of rice, wheat, and soybean cultivars

Normal cv. “Akitakomachi” (left), and Lodging Resistant cv. “Moeminori” (right) in direct seedingWith the aim of breeding paddy rice cultivars that enable the inexpensive production of lowland rice, we develop good tasting cultivars for business use capable of direct seeding and with a high yield, and cultivars resistant to such problems as disease and pests, rice blast, cold weather, and high temperatures.
We also breed cultivars with super-high yield and disease resistance to realize a stable supply of safe roughage. We breed high-quality wheat cultivars for bread, noodles and pastry that are resistant to cold and snow, yellow mosaic virus, and leaf rust. We also use DNA markers to breed barley cultivars with optimal processing characteristics and develop materials with resistance to a wide range of problems. We breed new soybean cultivars with high disease and pest resistance, lodging resistance, mechanization applicability such as resistance to pod bursting, and suitability for processing, while developing
labor-saving high-yield systems through improving plant types and agronomic characteristics.

Lowland crop rotation techniques utilizing subsurface irrigation-drainage facilities and direct seeding of well-drained paddy fields

p1_03While enhancing the performance of field moisture control such as drainage and irrigation functions by accurately adjusting groundwater levels, we develop soil management techniques that maintain soil fertility and achieve stable growth and yield of crops such as rice, soybeans and vegetables, combined with improved field workability. We are also reviewing
conventional mechanized cultivation systems that employ rotary tilling, and have established a large-scale lowland crop rotation system that makes it
possible to realize highly efficient and continuous rotation using high-speed machines such as chisel plows and grain drills.

Low-input and high-efficiency rice cultivation by direct seeding

Overgrowth of volunteer rice derived from dropped seed of forage riceWe are working on sowing uncoated seeds while simultaneously puddling with the aim of reducing input and improving the efficiency of direct-seeding techniques in flooded paddy fields in cold region. We also propose efficient fertilizer application methods and effective techniques for preventing rice from germinating from shattered seeds to develop low-input high-yield direct-seeding cultivation techniques for forage rice.

Soil management and pest control for sustainable agriculture

p1_05We elucidate the nutrient dynamics of organic matter and develop high-yield cultivation techniques by utilizing organic materials to establish a sustainable soil management technique.
We also evaluate the effects of cultural control in relation to developing pesticide-saving techniques against rice blast and phytophthora stem rot in soybeans. Furthermore, we analyze the biological reaction of weeds to cultural control as part of our development of comprehensive weed prevention and elimination techniques.

Combining our developed techniques with farm management

p1_07Our goal is always to identify methods of improving the profitability and productivity of farming. We have been conducting a series of research projects on farm management in the Tohoku region, especially for large-scale farmers and community-based farming groups; this is our starting point for investigating new farming models and utilizing new developments at NARO/TARC and other NARO institutes as actual farming techniques. We set up new farm management models that integrate the latest developments at NARO and the integrated business models that combine farming management and farmers’ new businesses for distribution of products and services from their farm. We present effective methods for revitalizing agriculture in the Tohoku region by introducing these new farming models based on market needs and evidence gathered in the field.
