Abstract

This study aims to determine the correct dose of atonic plant regulators and black soil doses on the growth and production of mustard greens. This research was conducted from March 2023 to May 2023, using a factorial Randomized Block Design (RBD), namely the concentration of atonic growth regulators, which consisted of 4 dose levels, namely 0ml, 3ml, 5ml, 7ml, and black soil, which consisted of 3 levels i.e. 0 gram, 5 ton/h, 10 ton/h. With 3 replications resulting in 36 experimental units. Observational variables consisted of plant height, number of leaves, root length, fresh weight, dry weight, and harvest index. Data were analyzed using analysis of variance (ANOVA) then continued with the Honest Significant Difference Test. The results of this study explained that there were changes in the observations observed both from plant height, number of leaves, root length, and dry weight with atonic growth regulators as growth stimulants for pakcoy mustard plants. And black soil to improve soil nutrients

Abstract

This research was conducted in Modong Village, Tulangan District, Sidoarjo Regency and continued with further research at the Agrotechnology Laboratory of Muhammadiyah Sidoarjo University. This research will be conducted in March-June 2023. This study used the Factorial Pattern Group Random design method, namely Red Lettuce Red Rapid and Lolorosa varieties with the provision of Gold Snail POC concentrations, namely 25 ml / polybag, 50 ml / polybag, 75 ml/polybag. The data obtained was analyzed using Fingerprint Analysis (Annova) and if the real difference was continued with the 5% Honest Real Difference Test (BNJ). The variables observed were plant height, number of leaves, wet weight, dry weight, root length and harvest index. Based on the results of the study showed that the red rapid lettuce variety is a variety that has a very real influence on the observation variebel of plant height, number of leaves and wet weight, but does not have a real effect on the observation variables of root length, dry weight and harvest index. Based on the results of the study showed that the red rapid lettuce variety is a variety that has a very real influence on the observation variebel of plant height, number of leaves and wet weight, but does not have a real effect on the observation variables of root length, dry weight and harvest index. The treatment of gold snail POC with 50 ml administration had a very real effect on the observation variable of plant height at the age of 28 HST

Abstract

Romaine lettuce production has decreased on a national scale. One effort that can be made to increase the production and yield of romaine lettuce is to cultivate it with proper fertilization and reduce the use of inorganic fertilizers and pesticides. This research aims to determine the interaction of cassava fertilizer doses and differences in planting distance for the growth and yield of romaine lettuce plants. The method used is a factorial randomized block design (RAK) with treatments of 5 tons/ha, 10 tons/ha, 15 tons/ha, and 20 tons/ha. as well as differences in planting distances of 15x20cm, 20x25cm and 25x25cm. The results of the treatment of cassava fertilizer dosage and plant spacing had a significant effect on the research variables of leaf number, but had no effect on plant height, root volume, wet weight and dry weight.
