Use of Palm Waste Cellulose as a Substitute for Common Growing Media in Aglaonema Growing
In order to evaluate the possibility use of palm waste cellulose as a substitute substrate for growing pot plants, an experiment was conducted in completely randomized block design with 6 replication and six treatments on Aglaonema sp. The treatments were 5 levels including 0, 25, 50, 75 and 100 palm celluloid wastes mixed with different rates of some amendments such as peat, coconut coir, perl...
متن کاملGrowing up or growing out? How soil pH and light affect seedling growth of a relictual rainforest tree
Seedling growth rates can have important long-term effects on forest dynamics. Environmental variables such as light availability and edaphic factors can exert a strong influence on seedling growth. In the wild, seedlings of Wollemi pine (Wollemia nobilis) grow on very acid soils (pH ∼4.3) in deeply shaded sites (∼3 % full sunlight). To examine the relative influences of these two factors on th...
متن کاملGrowing media constituents determine the microbial nitrogen conversions in organic growing media for horticulture
Vegetables and fruits are an important part of a healthy food diet, however, the eco-sustainability of the production of these can still be significantly improved. European farmers and consumers spend an estimated €15.5 billion per year on inorganic fertilizers and the production of N-fertilizers results in a high carbon footprint. We investigated if fertilizer type and medium constituents dete...
متن کاملAttribute Selection Measure in Decision Tree Growing
Laviniu Aurelian Badulescu University of Craiova, Faculty of Automation, Computers and Electronics, Software Engineering Department Abstract: One of the major tasks in Data Mining is classification. The growing of Decision Tree from data is a very efficient technique for learning classifiers. The selection of an attribute used to split the data set at each Decision Tree node is ...
متن کاملMapping Canopy Height and Growing Stock Volume Using Airborne Lidar, ALOS PALSAR and Landsat ETM+
We have investigated for forest plantations in Chile the stand-level retrieval of canopy height (CH) and growing stock volume (GSV) using Airborne Laser Scanner (ALS), ALOS PALSAR and Landsat. In a two-stage up-scaling approach, ensemble regression tree models (randomForest) were used to relate a suite of ALS canopy structure indices to stand-level in situ measurements of CH and GSV for 319 sta...
