Kajian Tingkat Pemberian Air Irigasi Tetes pada Budidaya Tanaman Lobak (Raphanus Sativus L.) dengan Media Tanam Cocopeat

Abstract

Radish is a root crop that requires the right amount of water. Proper water supply arrangements can be made by using drip irrigation. The aim of this research is to assess the efficiency of drip irrigation on radish plants (Raphanus sativus L.) on cocopeat growing media. This research was conducted on a greenhouse scale using a non-factorial completely randomized design, with 6 replications and 3 treatments, namely 100%, 75% and 50% field capacity. The results of this research were that the bulk density values obtained in the 100%, 75% and 50% field capacity treatments were respectively 0.0688 g/cm3, 0.0683 g/cm3 and 0.0682 g/cm3. The water use efficiency value in the 100% treatment was 99.83%, in the 75% treatment the field capacity was 99.78% and in the 50% treatment the field capacity was 99.76%. The highest water storage efficiency value was in the 100% field capacity treatment, namely 83.48%, then 75% field capacity, namely 82.91% and 50% field capacity, namely 81.29%. The wet weight of radish tubers respectively in the 100%, 75% and 50% field capacity treatments was 494 grams, 451.3 grams and 417.5 grams. The greatest water productivity was found in the 100% field capacity treatment, namely 65.49 kg/m3, then the 75% field capacity treatment, namely 63.81 kg/m3, and the 50% field capacity treatment, namely 63.14 kg/m3.
