Efektifitas Irigasi Kendi Dan Serasah Terhadap Jumlah Buah Kakao Selama Musim Kemarau

Abstract

The use of pitcher as a means of irrigation is the right choice in the use water efficiently but the effectiveness against cacao needs to be tested directly in the field. Its effective level can be known by using indicator that is the influence treatment to amount of cacao pods. The objective of this research is to find out the pitcher effectiveness as a means of cacao irrigation based on its influence to amount of cacao pods. This research was performed with field testing using pitcher number level that is 2, 4, 6 and 8 pitchers which combined with closing percentage of land surface that is 0, 30, 60 and 100%. The collecting data is maintained by counting of cacao pods. The effectiveness testing was conducted with statistical analysis using a Response Surface Model (RSM). The research result indicates that the most effective number of pitchers for maximize of amount pods cacao is 5 pitchers with covering the land surface is 65 percent. This model is considered to be valid with the coefficient determination value (R2) is 0.60.
