Construction and Evaluation of Pyramidal Hill for Cassava (Manihot Esculenta Crantz) Production in Bataan, Philippines

This study was conducted to assess the effects of pyramidal hill in the growth of cassava. However, as observed, the pyramidal hills did not remain pyramidal in shape due to soil compaction. In this study, three parameters were observed to evaluate the results of the study; crop parameters, soil parameters and yield parameters. There were two blocks that contained four treatments with five replications each treatment. Three of the four treatments were in different dimensions of pyramidal hill while one treatment is non-hilled and conventionally hoed which is used by common farmers. Three measurements of hill were used in reference to the base and height; (T1) 40 cm by 40 cm, (T2) 50 cm by 50 cm, (T3) 60 cm by 60 cm and (T4) 60 cm by 10 cm approximately. As a result, the highest averages of plant height recorded were in T3. In the aspect of soil compaction data based on penetrometer’s reading, the highest compaction was recorded in T4, while the rest of treatments had not significant differences. Significant differences were also observed in terms of yield parameters. It was recorded that replications in T3 for both blocks had the highest yield. The used of pyramidal in cassava production showed beneficial effects on the growth and yield of crops. Favorable increase in height was observed through measurements and higher weight was attained among tubers
