Abstract

The experiment was carried out in Ciumbuleuit, Hegarmanah Sub-district, Cidadap District, Bandung City, with an altitude of 875 meters above sea level with the Andosol order. The time of the experiment was started from June - August 2020. The purpose of this study was to study and analyze the effectiveness of the best natural growth regulators (ZPT) on the growth of celery (Apium graveolens L.). The experimental design used was a simple randomized block design (RBD) with four treatments and repeated six times. The treatments were A = 100% water (control), B = 30% shallot extract, C = 30% bean sprout extract, and D = 30% coconut water. The results showed that different natural ZPT administration had an effect on the growth of celery plants. And the experimental results based on independent tests showed that giving D treatment, coconut water at a concentration of 30% affected the growth of plant height 21 DAS, number of leaves 35 DAS and 42 DAS, leaf length 35 DAS and 42 DAS and the number of tillers 42 DAS on celery plants compared other treatment.

Abstract

This study aims to study the interaction between catfish populations and the type of growing media on the growth and yield of spinach (Amaranthus sp.) Cultivated by the aquaponics system. This research was conducted using an experimental method (experiment), from July to August 2020 in the experimental area of the PUSKOPAD complex, Tanjungsari District, Sumedang Regency. at an altitude of 850 m above sea level. The experimental design used was the Split Plot Design with the basic design of the RAK. Which consists of 2 factors with 2 repetitions. The first factor or mainplot is the catfish population (i) which consists of 4 levels, namely: (i1) = 0 tails, (i2) = 10 tails, (i3) = 20 tails, (i4) = 30 tails. The second factor or subplot is the type of planting medium (m) which consists of 4 types, namely: (m1) = Rockwool, (m2) = Oyster mushroom waste, (m3) = husk charcoal, (m4) = Pumice stone. Based on the results of experiments regarding the influence of catfish populations and the type of growing media on the growth and yield of spinach grown in the aquaponic system. That there was an interaction between the treatment of catfish populations and the type of planting medium on the parameters of the observation of plant height at 20 days after planting (DAS) and 30 DAS and leaf number at 10 DAS and 35 DAS. The use of pumice growing media is best used for the cultivation of spinach in an aquaponic system and a population of 20 catfish is sufficient to provide the nutrient needs needed by spinach plants.
