Reynaldo R. Javier ABSTRACT The percentage organic matter and total N and Olsen P in the soil were significantly increased with 120-180 kg N ha-1 organic matter manure application. The application of organic manure at increasing rates (611P180 kg N ha-1) shortened the days to tassel, silk, and harvest of baby corn; increased the leaf …

Doris Po Quita and Misael T. Diputado, Jr. ABSTRACT Nutrient application, in general, increased plant size and number of leaves per plant and enhanced thy matter production in plant. Low nitrogen to potassium ratio resulted to the production of shorter internodes and with more intense bract color. Plants applied with high N-K. ratio were taller, …
