The influence of silica and nitrogen fertilization on growth and yield of Peta and Chianung 242 lowland rice varieties
(1965)Rice culture will remain the focus of agricultural research in Asia until more of the countries become self-sufficient in this crop. More scientific results from laboratory and field experiments must be pooled and applied ... -
A study of the physiological characteristics of Peta rice variety in relation to time of nitrogen fertilization
(1966)The purpose of this study was to know the physiological characteristics of Peta rice variety as influenced by the time of nitrogen fertilization. The importance of this study was to help the farmers know the proper time ... -
The nutrient composition, digestibility and nitrogen retention by sheep of four vacuum-ensiled grasses
(1969)The chemical composition of forage or any other feedstuff is a very useful but insufficient information on which to judge its nutritive value for a particular class of livestock. To get a better index, it is necessary to ... -
Survival of completely submerged rice plants
(1970)The survival of rice plant under completely submerged condition is influenced by the duration of submergence, water temperature, water turbidity, light intensity, water depth, stage of growth, variety and nitrogen level. The ... -
The effect of restricted feeding during the growing period of Kimber White Leghorn pullets on first-year performance and on egg quality
(1972)Two hundred forty, 10-week-old Kimber S. C. White Leghorn pullets were used to measure the effects of varying levels of feed restrictions from 12 to 22 weeks of age. This experiment had four treatments as follows: Treatment ... -
Environmental effects on the resistance of rice seedlings to complete submergence
(Crop Science Society of America (CSSA), 1972-03-01)The survival of rice seedlings (<em>Oryza sativa L.</em>) after complete Submergence in water decreased with increased duration of submergence; with increased depth, temperature, and turbidity of water; and with increased ... -
Utilization of sugarcane bagasse mulch in tomato (Lycopersicon lycopersicum (L.) Karsten) production
(1978)Three sets of studies (greenhouse tests, laboratory and field experiments) were conducted to gain information on how to maximize the utilization of sugarcane bagasse-mulch in tomato production using the cultivar Marikit. The ... -
Physiological responses of cockerels given crude mimosine acid extract (CMAE) and exogenous gonadotrophins
(1979)A 2 x 4 factorial experiment was conducted to evaluate the effects of crude mimosine acid extract (CMAE) with or without exogenous gonadotrophins on the physiological responses of the cockerels; and to verify whether ... -
Agro-economic evaluation of four vegetable cropping patterns for north Florida as influenced by crop and fertilizer management levels
(1980)Appropriate crop management technologies for year-round vegetable cropping systems are essential to increase productivity and improve farm income among small-scale vegetable farmers. A 2-year study was conducted to determine ... -
