Jose R. Pardales, Jr ABSTRACT Growth, development and harvest attributes of taro were more apparently affected by mulching treatment than by planting depth. Mulched plants exhibited superior height and LAI and markedly higher total and corm dry matter (DM) accumulation than their unmulched counterparts. Most of the harvest characters were significantly greater when taro was …
R.N. McArdle and J.C. Bouwkamp ABSTRACT Sub-terminal stem cuttings of two winged bean genotypes, P1 413214 and PI 413216 were treated with three levels of indolebutyric acid (IBA) and sampled after 15, 17, 19 and 23 days to examine rooting response. IBA treatment dramatically increased root dry weight, root length and root number in PI …
Reynaldo R. Javier ABSTRACT Macroptilium lathyroides and Vigna luteola with either intact or removed adventitious roots from the immersed stem, were flooded con-tinuously for 15 and 30 days from the start of flowering. The removal of adventitious roots from the immersed stem of the flooded plants hastened leaf chlorosis and abscission. Dry matter yield (shoots …
Benjamin C. Agarcio, Jr and Joachim Sauerborn ABSTRACT Optimum mungbean yield was obtained when the crop was fertilized with 30 kg P2O5/ha. Beyond this level, a reduction in yield occurred. The addition of nitrogen fertilizer at the rate of 30 and 60 kg/ha decreased mungbean yield. Weed count and weed weights increased with increasing rate …
Alan L. Presbitero and Vincent Christian Quimbo ABSTRACT The effect of percent slopes on the erosion coefficient of Umingan, Maasin and Malitbog clays was found to be highly significant. For all the soil types, erosion coefficient had a positive relationship with the slope. Third degree polynomial equations described the slope-erosion coefficient relationship for Umingan and …

Victor B. Asio ABSTRACT Degraded uplands are widespread in the country but only limited information is available about this type of ecosystem. In view of this, a study was conducted to evaluate the characteristics and ecological qualities of soils in a degraded upland area in Manjuyod, Negros Oriental. Results indicated that the soils have generally …
Alan L. Presbitero ABSTRACT The monthly water release operating policy for a single multi-purpose reservoir system at each stage of development of the service area was defined using Discrete Differential Dynamic Programming (DDDP) optimization analytical technique and simulation model developed in a master program for a mainframe computer type. Irrigation and flood control were the …
F.A. Salares and R.M. Gapasin ABSTRACT A pot experiment was conducted to determine the most susceptible stage of growth of ampalaya, Momordica charantira L. to the root-knot nematode, Meloidogyne incognita infestation and the inoculum density of the nematode that could affect the yield. Gall and egg mass indices and nematode population recovered from the roots …
Ramon R. Orias ABSTRACT Pressure drop (mm H20/m depth) was generally higher in high-moisture chips than in low-moisture chips. Relationships were found to be normally linear for sweetpotato (Ipomoea batatas) and taro (Colocasia esculenta) and logarithmically linear for cassava (Manihot esculenta). Porosity also increased with moisture, but despite the presence of more void fraction, pressure …
Linda S. de la Rosa and Linda B. Mabesa ABSTRACT Wild yams (Dioscorea hispida Dennst.), locally known as nami or kot, was detoxified and processed into flour. Detoxification was carried out by salting thinly-sliced tubers and subsequently washing these under running water. Results showed that detoxification can be achieved either by treating the thin slices …
