In the present study, which was conducted at Polatlı agricultural farms, three different applications were used for wheat production. These were conventional tillage, reduced tillage and direct s...
Field experiments were performed to identify an effective fertilizing scheme for direct-seeding rice (DSR) fields in the Taihu Lake Basin in east China. Based on local traditions, 3 typical fertilizin...
An on-farm experiment was conducted at Zanyokwe irrigation scheme (ZIS) in the Eastern Cape Province of South Africa (SA) to evaluate comparative performance of direct seeded and transplanted green ma...
We have investigated the use of air-assisted strip seeding for direct seeding in flooded paddy fields. A seeder was developed using a commercially available granule applicator remodelled for tractor i...
Purpose: The paper compares the effect of five different direct seeding methods to the conventional tillage on the emerging and yield of silage corn (Zea may L.) in two different pedo-ecological condi...
为了探索水稻种绳直播机对地表不平度激励的适应性,进行了动态模拟试验。根据样机的结构特点,设计了由角位移传感器、数据采集卡和计算机等构成的地表不平度检测系统。检测了由旋耕形成的原始地表不平度和经过种绳直播机作业后形成的地表不平度,应用Matlab软件对信号进行了时域和频域分析。应用等同法建立了系统的传递函数,分析了系统的动态特性。研究结果表明,由种绳直播机和土壤等构成的土壤—机器系统是一个具有一阶惯...
For the introduction of low temperature germinability (LTG),seed longevity and accelerated coleoptile growth derived from foreign varieties to Japanese elite varieties to breed rice varieties for dire...
Submerged direct-seeded rice is more susceptible to lodging during the ripening period than is transplanted rice. Comparing different seeding methods of direct seeding cultivation, lodging resistance ...
Effect of earthing up on lodging in direct-seeding rice culture.
Establishment control of rice seedling in direct-seeding culture by reducing the excess seedlings.
To understand the growth habit of rice plants under direct seedling cultivation on well-drained paddy fields, physiological and ecological characteristics were compared among directly seeded and trans...
Direct seeding is one possible improvement for future low-cost and labor-saving rice production. This study was conducted to determine whether high yielding cultivars can be adapted to direct seeding...
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...
The effects of an irregular density of seedling establishments in direct seeding cultivation of rice (Oryza sativa L.) on growth and grain yield and their relations were investigated in a paddy field...
Direct-seeding culture without tillage and covering soil using the Y-shaped seeding furrow was examined in 1997 and 1998 at a poorly drained paddy field in Hachirogata(Akita Pref., Japan). The percen...
