Pengaruh Pemberian Bokashi Kotoran Sapi Terhadap Beberapa Sifat Fisik Tanah Dan Pertumbuhan Tanaman Tomat ( Solanum Lycopersicum L) Pada Entisols Sidera

This study aims to determine the effect of giving bokashi cow manure to some soil physical properties and growth of tomato plants (Solanum lycopersicum L.) on Sidis Entisols. The study was conducted at the Faculty of Agriculture Greenhouse and analysis of soil and plants was carried out at the Soil Science Laboratory, Faculty of Agriculture, Tadulako University, Palu. Location of soil sampling in Sidera Village, Biromaru District, Sigi Regency, Central Sulawesi Province. When the study began from December 2019 to March 2020. This research was conducted using a completely randomized design (CRD) consisting of 6 treatments namely, B0 = no treatment (control), B1 = 5 tons / ha-1 or equivalent to 16.23 g / pot-1, B2 = 10 tons / ha-1 or equivalent to 32.46 g / pot-1, B3 = 15 tons / ha-1 or equivalent to 48.70 g / pot-1, B4 = 20 tons / ha-1 or equivalent to 64.93 g / pot-1 , B5 = 25 tons / ha-1 or equivalent to 81.16 g / pot-1, each treatment was repeated 3 times to obtain 6 x 3 = 18 experimental units. The results showed that the bokashi treatment of cow dung had a very significant effect on changes in soil physical properties and growth of tomato plants (Solanum lycopersicum L.) on the observed variables, namely: soil content weight, permeability, moisture content of field capacity, soil porosity, soil dry weight and effect significantly on the total root length and plant height variables. The dosage of bokashi cow dung as much as 25 tons ha-1 can significantly affect changes in soil physical properties compared to other treatments.
