Abstract

Chrysanthemum (Chrysanthemum spp.) is one of the ornamental plants that has the potential to be developed in Indonesia. In general, chrysanthemums are cultivated as cut flowers and potted flowers. The diversity of colors and shapes of chrysanthemums and the low rate of flower wilting are the main attractions of chrysanthemum plants. The demand for chrysanthemum flowers increases by 25% every year so that cultivation and production technology is needed to meet the needs of the national market. Fertilization is the addition of nutrients to plants to increase plant growth and development. One of the materials that can be given to plants is biochar. This study used one treatment in a Randomized Block Design (RAK) with four replications. The treatment of  the composition of the growing media consisted of 4 levels. Observations were made on the growth of chrysanthemum plants including plant height and number of leaves. The results showed that the planting media treatment with a composition of 50% soil + 50% biochar produced the best plant height and number of leaves compared to other treatments. This shows that the addition of biochar with the right ratio in the growing media can increase the growth of chrysanthemum plants.

Abstract

The hydroponic system in a greenhouse for cauliflower cultivation can be a solution to the problem of conventional cultivation, but its needed for the cultivars that are most suitable for hydroponic systems, especially the Nutrient Film Technique (NFT) system. This study aims to (1) evaluate the growth and production yields of several cultivars of cauliflower in the Nutrient Film Technique (NFT) hydroponic system, (2) the best cultivar for cultivation of NFT hydroponic method. This study used a lowland cauliflower cultivars, namely PM 126, Mona, Diamond 40, Orient, and Pertiwi with 5 times. The data obtained from each observation variable were analyzed by means of analysis of variance which was carried out with a follow-up test with Honest Significant Differences (BNJ) at the 5% level. The results showed that cauliflower cultivars had different growth responses to the NFT system. Pertiwi cultivar had the best plant height compared to other cultivars, while the variables of leaf width, leaf length, time of flower emergence, flower weight, flower diameter and root length between cultivars showed no significant difference. The cultivar that shows good production results and is suitable for NFT hydroponic systems is PM126.

Abstract

Curly red chilies are one of the horticultural products that have the potential to be developed because they have high economic value, however the production of curly red chilies in Lampung Province has continued to decline in the last 4 years. One way to increase production value is to increase soil fertility by increasing fertilization. Fertilization is carried out to replace nutrients lost due to rainwater by using fertilizer containing the elements N, P and K, one of which is KNO3 and KH2PO4 fertilizer. The aim of this research is to find out which combination of KNO3 and KH2PO4 is better and to find out whether the single application of KNO3 and KH2PO4 is good for the growth and yield of curly red chili plants. The research used a factorial randomized block design consisting of 2 factors. The first factor is the concentration of KNO3 fertilizer, with 3 levels, namely 3; 4; 5g/l. The second factor is the concentration of KH2PO4 Fertilizer, with 3 levels of 3,5; 4,5; 5,5g/l. Each treatment was repeated 3 times, so there were 9 treatment combinations and 27 experimental units. The variables observed were plant height, stem diameter, number of shoots, fruit weight per plant, number of fruit per plant and root length. Potassium nitrate (KNO3) fertilizer treatment with a concentration of 5 g/l and potassium dihydrophosphate (KH2PO4) 5,5 g/l had a significant effect on plant growth in plant height. Providing potassium nitrate (KNO3) fertilizer with a concentration of 4 g/l and potassium dihydrophosphate (KH2PO4) 5,5 g/l had a significant effect on plant growth including the number of branches and stem diameter. Providing potassium nitrate (KNO3) fertilizer with a concentration of 4 g/l and potassium dihydrophosphate (KH2PO4) 4,5 g/l had a significant effect on plant yields including the number of fruit/plants and the weight of the fruit/plant.

Abstract

Organic chili cultivation has become a necessity nowadays as awareness increases about the dangers of chemical residues used in conventional cultivation practices. Chili is one of three main of vegetables commodities in Lampung. However, pepper yellow leaf curl disease is still a major obstacle faced by farmers to increase chili productivity. Therefore, the aim of this research is to study the characteristics of symptoms and the incidence rate of pepper yellow leaf cull disease of Capsicum annuum L. and Capsicum frutescens in organic cultivation practice. The results shown that the characteristics or early symptoms of pepper yellow leaf curl disease on chilies are yellowing of young leaves, mosaic and malformation which are found in C. annuum L and C. frutescens. The intensity of disease attacks on chili plants by giving POC from the Mimosa pudica roots (PM) gave positive efect with an average low attack intensity in the 8th week, namely 32% compared to giving POC from bamboo roots (AB) with an average attack intensity 45.5%. This indicates that POC from the roots of Mimosa pudica (PM) is capable of being a bioprotectant for chili plants. The application of POC type 3 also provided a positive response with a low intensity of pepper yellow leaf curl disease on C. frutescens.
