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...
We investigated the relationship between the forms of emergence and the seedling growth of rice(Oryza sativa L.)and the effects of plant growth regulators on the forms of emergence and seedling growth...
The growth characteristics of hill-seeded rice were compared with those of broadcast-seeded rice to establish the submerged direct seeding cultivation using a newly developed 'Shooting hill-seeder'. ...
The effects of stepwise raising of the water level on tiller growth in rice plants were examined. When the plant age in leaf number of the main stem was 7.5, the plants were submerged to a level of th...
The effects of stepwise raising of the water level on tiller growth in rice plants were examined. When the plant age in leaf number of the main stem was 7.5, the plants were submerged to a level of th...
The changes in number of spikelets per panicle (SN) under saline conditions as affected by the application of plant growth regulators were determined. A lowland rice cultivar IR28 whose SN is reduced...
It has been reported that hill-seeded rice, using a newly developed "Shooting hill-seeder", shows high lodging resistance and ripening ability in the warmer regions of Japan. It suggests possibility f...
This study was undertaken to evaluate the effect of short period high water temperature (35°C) on the growth response of immature leaves in rice plants. The test plants was exposed to high water temp...
It is possible to analyze the chemical constituents or physical properties of each rice grain, and attempts are being made to clarify the relationship between the analytical results and position of t...
In this paper we investigated water status and chlorophyll content of tolerant and sensitive rice varieties after being subjected to dry wind treatment using a wind tunnel. Two rice varieties, Naepun...
A method to demonstrate varietal differences in seedling establishment of rice under low temperatures and methods of data analyses are discussed. Nursery boxes were filled with sieved soil up to 0, 4...
The purpose of the present paper is to identify morphological and physiological traits of acid soil tolerant varieties of rice plants (Oryza sativa L.) in Narathiwat Province of Southern Thailand whe...
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...
Cool weather is a serious climatic constraint for rice cultivation in hilly and mountainous regions. Deep-flood irrigation is known as the most effective method to protect rice plants from cool weath...
