No-tillage with cover crop has great potential to improve soil quality, however, it is still not clear what no-tillage seeding technique should be used under cover crop residue mulch in upland crop pr...
In a hilly area in Lampung State, the southern end of Sumatra Island in Indonesia, coffee is commonly cultivated on hillsides with steep slopes and soil erosion affects sustainable coffee production. ...
To elucidate the effect of no-tillage practice on the root system development and productivity in a wheat-soybean rotation system in Japan, we continuously cultivated these crops under tilled and non-...
设计了一种由机具导向架、液压系统和以DSP为核心的控制单元组成的机具导向系统。根据与该系统配套的拖拉机确定了机具导向架的基本参数,并通过对机具导向架外框不同位置的受力分析得出该系统可以推动的最大负载满足机具田间作业的要求。以JDT654L型拖拉机为试验平台,进行了系统性能试验。结果表明,机具导向架的调节范围为-10.8°~10.7°;该系统换向平稳,换向时间短,对输入信号有较好的响应和控制精度,跟...
In Japan, wheat-rice crop rotation with the practice of rice transplanting has been quite popular in the past. Mechanized direct-planted wheat-rice sequential cropping was developed at the Aichi Prefe...
No-tillage often affects crop root development due to the higher mechanical impedance to root elongation, resulting in yield reduction under an unfavorable rainfall pattern, such as drought. In this s...
The effects of winter weeds on the growth and yield of direct-seeded rice (Oryza sativa L. cv. Akebono) were evaluated in a no-tillage dry paddy field where Alopecurus aequalis Sobol. var. amurensis (...
No-tillage direct seeding of rice (Oryza sativa L.) in early spring was conducted to disperse seeding work and to improve heading time in cold regions. Germinated seeds were seeded every 5 days in 19...
Characteristics of no-tillage cropping techniques as agriculture for environmental preservation and research subjects in the future.
Improved no-tillage seeder and managing a no-tillage seeding system.
Field trials were conducted to examine the growth and yield characteristics of rice (Oryza sativa L.) cultivated in deep-flood irrigation under no-tillage cultivation with single basal fertilization t...
No-tillage soybean culture using winter barley as a cover crop was developed to control annual summer weeds and reduce labor. With this cover crop system, the soybean yield is higher than with a non-...
No-tillage cultivation”+“Herbicide-tolerant GM cultivars”=Admirable technology that we have longed for?
Buffering foliar K solutions to pH 4 increased K uptake and lint yield of cotton (Gossypium hirsutum L.). Research was conducted (1995-1997) on a Collins silt loam (coarse-silty, mixed, active, acid, ...
