Growth and Yield Response of Cucumber (Cucumis Sativus L.) Plants Due to Coffee Grounds and NPK Fertilizer Application

Abstract

Abstract: Cucumber plants originate from Asia, many mention the origin of cucumber plants in North Asia, cucumbers are included in the cucurbit family (Cucurbitaceae). The purpose of this study was to see the provision of coffee grounds compost and NPK and to see the interaction of the two treatments tested. This study used a Randomized Block Design (RAK) consisting of 2 treatment factors on cucumber plants which were repeated 3 times. The first factor is coffee grounds compost with 4 treatment levels, namely: Ko = control, K1 = 150 gr / polybag, K2 = 300 gr / polybag and K3 = 450 gr / polybag. The second factor is NPK with 4 treatment levels, namely: No = control, N1 = 2 gr / polybag, N2 = 4 gr / polybag and N3 = 6 gr / polybag. Data analysis used analysis of variance (ANOVA). The results of the study stated that the best provision of coffee grounds compost was at K3 = 450 gr/polybag for all parameters tested, while the best provision of NPK was at N2 = 4 gr/polybag for all parameters tested. The results of the interaction of the combination of providing coffee grounds compost in the treatment with a concentration of K3 = 450 gr/polybag and providing NPK in the treatment N3 = 6 gr/polybag (K3N3) had a significant effect on the fruit length parameter with an average root length of 23.77 cm.
