Abstract
This study was conducted to determine the growth and yield performance of radish as influenced by mulching. The study was conducted in a field experiment of the Ramon- Magsaysay-Center for Agricultural Resources and Environment Studies. Two treatments were established, the plot with mulch (t1) and no mulch (T2), each treatment were replicated three times. Results of the study showed that higher survival rate (62.89%) was recorded from plots with mulch compared to plot with no mulch, while number of days to form tubers, showed that plots with mulch formed tubers early (25 days) compared to the plant of no mulch (32 days), higher weed biomass was gathered from plots with no mulch with an average of 142.92 g, while the weed biomass from plots with mulch obtained an average of 90.87g. Time of irrigation was shorter from plots with mulch (8min) compared to plot with no mulch with 10 min. Higher soil temperature was recorded from plot with no mulch (35degrees celcius) compared to plots with mulch (32 degrees celcius). In terms of plant height, taller plants observed from plot with mulch (9.91 inches) compared to plot with no mulch (9.29 inches), however no significant difference was recorded in terms of tuber length. Yield of radish plant with mulch was recorded higher compared to no mulch.
