Abstract

The increase of oyster mushroom farmers in wonogiri will be impact immediately on increasing waste baglog. One of the utilization is to be medium on hydroponic substrate for growing mustard greens and it will combined with charcoal and various types of nutrients. The research was conducted from October to December 2015 at the Greenhouse C and Laboratory EMPT UNS.the research employed completely random design (CRD) with two factor that is ratio of medium and various types of nutrients. The result of research showed that interaction between ratio of medium and various types affected significantly  the parameters of leaf area, leaf fresh weight and leaf biomass. Root fresh weight, root volume, root length and root biomass is only influenced by the type of nutrition with the ab mix is the most good in improving and supplying nutrients

Abstract

This study aims to determine the differences in the growth response of green curly lettuce to the differentiation treatment of LED lighting with different spectrum in indoor hydroponics. The research was conducted from October to November 2017. The experimental design used was experimental with 1 lighting factor with 5 levels, there are sunlight (P0), LED 20% blue: 80% red (P1), LED 80% blue: 20% red (P2), 50% blue LED: 50 % red (P3), and 100% white daylight (P4). Observational variables included plant height, leaf number, leaf area, leaf color, total wet weight, leaf wet weight, wet root weight and dry weight of the plant. The result of this experiment showed that LED irradiation have affect the treatment are plant height, leaf number, leaf area, chlorophyll content, fresh weight of harvest, root length, and dry weight of brackets. While those that have no significant effect are the wet weight of the roots. The results showed that between LED irradiation treatment L1, L2, L3, and L4 showed that treatment L2 with 80% blue spectrum composition: 20% red showed better growth based on: high plant, chlorophyll content, and root length. Treatment with L4 with white LED showed better growth based on the number of leaves, leaf area, fresh weight of harvest, root wet weight, and dry weight of total biomass. The results below the sunlight better than the LED irradiation treatment, because the intensity of LED far low and lack of controlled environmental conditions technology and management for growing lettuce. In all of LED treatment still looked etiolation because light intensity was not optimal yet.

Abstract

Arrowroot is a plant that potential to be one of the alternative food source for the community. The intensity of the light received by the plant is one of the influential factors important for plant growth. This study was conducted to determine the arrowroot plant growth analysis at different light. This research was conducted at the Experimental Farm Faculty of Agriculture, University of Sebelas Maret in Jumantono Karanganyar. This study uses a randomized block design Complete (RAKL) one treatment factor with four levels ie without shade, 31% shade, 51% shade and 73% shade. Data were analyzed by analysis of variance and if there is a significant difference continued with DMRT (Duncan Multiple Range Test) level of 5%. The results showed that the treatment of 51% shade known to give better growth results in some growth variables observed were plant height, leaf area index (LAI), segment length and chlorophyll contents.
