Adaptability of different irrigated lowland rice selections during wet and dry season planting at CPU Zarraga experimental farm
(Central Philippine University, 2002-11)
The studies were conducted from June 2001 to March 2002 at CPU Zarraga Experimental farm to determine the yield potential, range of adaptability and field reactions to major insect pests and diseases of promising rice ...

(Central Philippine University, 2003-07)
The studies were conducted from June 2002 to May 2003 at the CPU Zarraga experimental farm to determine the yield potentials and range of adaptability of promising rice selections and to identify those that could be ...
Adaptability of different MASIPAG rice selections under Central Philippine University experimental farm conditions under wet season planting
(Central Philippine University, 2006-03)
The study was conducted on July 10, 2005 to December 29, 2005 at CPU farm Tuburan Sulbod, Zarraga, Iloilo to assess the agronomic and yield characteristics of MASIPAG rice selections, test their adaptability and identify ...
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....
