Abstract

This study aims to determine the effect of the combination of AB mix nutrients with liquid organic fertilizer (LOF) of tofu liquid waste on the growth and yield of lettuce plants and to obtain the best combination for the growth and yield of lettuce hydroponically. This study used a non-factorial Randomized Block Design (RBD), consisting of a comparison of nutritional treatments, namely: N1 = 100% AB mix + 0% LOF of liquid waste tofu, N2= 75% AB mix + 25% LOF of tofu liquid waste, N3= 50% AB mix + 50% LOF of tofu liquid waste, N4= 25% AB mix + 75 % LOF of tofu liquid waste, N5= 100% LOF of waste liquid tofu which consists of 4 replications. Parameters observed were plant height, number of leaves, leaf length, leaf width, root length, fresh weight, root volume and weight fit for consumption. The results showed that the administration of 50% AB mix + 50% LOF of tofu liquid waste and 25% AB mix + 75% LOF of tofu liquid waste showed results that tended to be the same but the results of the combination of 75% AB mix + 25% LOF of tofu liquid waste were higher. On the parameters of the number of leaves is 11.12 strands, fresh weight is 66.40 g and suitable weight for consumption is 58.31 g.

Summary

Introduction

Lettuce (Lactuca sativa L.) is one of the vegetable crops that is quite popular with the community so that it has good prospects for development. The leaves of this plant are consumed in fresh form, can be used as decoration in food dishes or fresh vegetables and as a complement to cooking. Lettuce provides health benefits because it contains high enough nutrients. Lettuce and vegetables are generally cultivated hydroponically because they have a relatively fast harvest life and short roots. Hydroponics is a cultivation system without using soil but utilizing water or water power by using nutrients in dissolved form without land use. Hydroponic cultivation can be done practically, does not need a large yard and the capital is not too large, especially for hydroponic cultivation with a wick system [2]
