The effect of different yeast (Saccharomyces cerevisiae) preparations in controlling odor emission and flies in animal manures
(Central Philippine University, 2005-05)
The study was conducted to determine which of the yeast preparation could effectively control odor emission and fly infestation among swine, poultry, cattle, and goat manure. The treatments were laid out in a factorial ...
The effect of different green and animal manures on the growth and yield of potted lettuce, cabbage and cauliflower
(Central Philippine University, 2011-12)
The objectives of the study were to determine the growth and yield and profitability of growing potted cabbage, cauliflower, and lettuce as influenced by different green plant and animal manures. The seven experimental ...
A comparative study on the effectiveness of nature farming and conventional farming technologies on the growth and yield of Dapit-saka rice selection
(Central Philippine University, 2004-09)
Insects found feeding on rice at the early stage, that is, at three weeks after transplanting (WAT) were the rice whorl maggots (Hydrillia philippina), white leafhoppers (Cofana spectra), green leafhoppers (Nephotettix ...
A comparative study on the effectiveness of nature farming and conventional farming technologies on the growth and yield of Dapit-saka rice selection
(Central Philippine University, 2007-10)
The agronomic characteristics and yield of Dapit Saka rice selection grown using the conventional farming and nature farming methods were compared and the effect of the different nature farming concoctions against rice pests and natural enemies were evaluated from November 2002 to February 2003 in Bongco, Pototan, Iloilo. Results revealed that rice whorl maggots (Hydrellia philippina), white leafhoppers (Cofana spectra), green leafhoppers (Nephotettix virescens), brown planthopper (Nilaparvata lugens), rice stemborers (Scirpophaga innotata) and grasshoppers (Oxya hyla intricata) were found feeding on rice. Natural enemies observed included a mirid bug (Cyrtorhinus lividipennis), lady beetle (Micraspis crocea), damselfly (Agriocnemis spp.), ground beetle (Ophionea nigrofasciata), vespid wasp and spiders (Lynx spiders, Oxyopes spp.; dwarf spider, Atypena formosana; Orb spider, Argiope catenulata; and long-jawed spider, Tetragnatha maxillosa). It was noted that the use of nature farming technology and the absence of pesticides in the control resulted in more natural enemies. However, plants grown in conventional farming were significantly taller, had the most number of tillers, and heaviest panicles. These resulted in the highest grain yield of 3,466 kg/ha, a net income of P19,643.00 and an ROI of 130.80 % . These values exceeded those of plants in the nature farming technology by 1,641 kg/ha, P 5,612.65 and 25.80%, respectively....
Growth, yield and nutrient concentration of two rice varieties treated with four levels of salt and nitrogen
(1984)
The effect of NaCl and nitrogen on the soil solution EC and pH; and on the growth, yield, and nutrient concentration of IR52 and IR26 rice varieties were studied in a pot experiment in the screenhouse of the Department of ...
