Reynaldo R. Javier ABSTRACT Seven tropical pasture legume species were grown in pots inside the glass-house. At the start of flowering stage, plants were continuously flooded to 5 cm above the soil surface for 10 and 21 days. Dry weights of shoots, roots and no-dules of the flooded plants were compared to the corresponding unflooded […]

Benjamin C. Agarcio, Jr. ABSTRACT A field experiment was conducted to evaluate the effect of row spacing and time of weeding on the competitiveness of mungbean against weeds. Dry weed weight was generally higher at wider row spacing than at closer spacing because of more space available for weed growth. Controlling weeds in mungbean within
R.K. Somashekar, Siddaramaiah, K.P. Srinath and P. Venkatasubbaiah ABSTRACT Bavistin, a systemic fungicide, was tested for its mitodepressive and antimitotic effect on coffee (Coffea arabica L.). A drastic reduction in the mitotic index occurred as the concentration and duration of treatment increased. Bavistin also influenced the frequency of mitotic phases and behaved as a potential

Gloria L. Tupas ABSTRACT Root samples of sweet potato were examined for possible microbial association. Examination of roots from relatively open marginal soils exhibited evidence of mycorrhizal infection particularly the vesicular-arbuscular type. The capability of sweet potato for mycorrhizal association could be one of its adaptations for growth and productivity in marginal soils. Keywords: Sweet

Pablito L. Sevenorio and Rodolfo G. Escalada ABSTRACT The use of either soybean or mungo as green manure crop did not significantly affect the agronomic characters, yield and yield components of sweet potato except the number of marketable tubers. Stage of green manure decomposition greatly influenced vine length and leaf area index during the second
John C. Bouwkamp ABSTRACT In 4 sweet potato cultivars studied, harvest indices and dry weight accumulations of sweet potato storage roots and total plant dry weight increased throughout the growing season, but declined during the later part of the season. Vine dry weight slowly increased reaching a maximum at 14-16 weeks after transplanting, then slowly
