M. Anandaraj ABSTRACT Bordeaux mixture is a copper compound which is extensively used to prevent fruit rot in arecanut (Areca catechu Linn.) caused by the fungus Phytophthora arecae (Coleman) Pethybridge. It is usually mixed with adhesives to improve its retention. The quantity of copper retained on areca fruit surface sprayed with 1% Bordeaux mixture added …

Nestor M. Gloria ABSTRACT An old abaca plantation was subjected to butcher harvest as a rejuvena-tion process. The subsequent ratoons were evaluated in terms of growth and fiber dimensions as influenced by plant density and nitrogen level. Replants served as checks in determining the merits of ratooning. Ratoons emerged approximately 13 days earlier, had more …

S. Ramanathan, M. Anantharaman and K.R. Lakshmi ABSTRACT Ninety cassava farmers were interviewed to determine the configuration of characteristics which would differentiate the low from the high-knowledge level farmers. Results indicate that farmers with these characteristics in the corresponding variables, i.e. program participation (non-program), age (young), education (low), credit (not availed) and area under cassava …

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 …
