Abstract

Ginger production has decreased over the past year and this could be due to less than optimal plant cultivation. Selection of quality seeds and optimal standards will provide optimal production impacts. Early detection of pathogens in ginger seeds can be an effort to maintain production potential. The aim of this research is to identify the diversity of ginger pathogens that appear in nurseries as an effort to maintain the production potential of ginger plants. This research looked at the pathogens that appeared in red ginger, emprit ginger and elephant ginger which were sown in burlap sacks for one month. Disease symptoms that appear during observation were observed and isolated and were identified the pathogen. Observation results showed that red ginger's healthy rhizome was higher than other ginger. Pathogens identified in three types of ginger include Sclerotium rolfsii, Penicillium sp and Aspergillus sp. Sclerotium rolfsii is the dominant pathogen and has a high attack rate on elephant ginger clones. Keywords: Sclerotium rolfsii, Zingiberales officinale, Rhizome

Abstract

One of the keys to successful pakcoy hydroponic cultivation is nutrition. In addition to AB Mix nutrients, sources of nutrients from single fertilizers, compound fertilizers, and foliar fertilizers can also be used as hydroponic nutrition alternatives. The purpose of this study was to determine the interaction of nutrient treatment and foliar fertilizer concentration, to obtain the best type of nutrition, and to obtain the best concentration of foliar fertilizer on growth and yield of pakcoy with the NFT hydroponic system. This research was carried out in greenhouse of Polihidro Farm, Lampung State Polytechnic in June-August 2022. This research used Split Plot Randomized Block Design with the main plot, namely type of nutritions consist of AB Mix 10 ml.l-1 (N1) nutrients, NPK 16 - 16 – 16 2.5 g.l-1 (N2), and nutrients ZA : TSP : KCl (1 g.l-1 : 0.5 g.l-1 : 0.5 g.l-1 ) (N3). Subplots namely foliar fertilizer concentration consist of 0.5 g.l-1 (P1), 1 g.l-1 (P2), 1.5 g.l-1 (P3), 2 g.l-1 (P4), 2.5 g.l-1 (P5), and 3 g.l -1 (P6). The results showed that there was no interaction between type of nutrient and concentration of foliar fertilizer. AB Mix Nutrition 10 ml.l-1 provides the best growth and yield for pakcoy plants. The concentration of foliar fertilizer had no significant effect on growth and yield of pakcoy.

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.
