Abstract

ABSTRACT   This study aimed to compare the application of environment-friendly cultivation technology on the quality of strawberries. The experimental design using a factorial in a randomized block design (RAK), with 2 factors, namely: 1). Farmers treatment technology that chicken manure 20 t / ha + Urine Rabbits 1: 5 liters of water; 2). Treatment T. koningii 15 g / kg of soil in chicken manure 5 tons / ha). Data were analyzed by t test statistics, if different continued with test Duncun at 0.05. Research results show that treatment of PP (T. koningii Technology) has Vitamin C is 27.1 mg / 100g, higher than the Treatment PT (Technology Farmers) is 22.5 mg / 100g. The vitamin C content of the variables were not significantly different between treatments, while the variable texture of the fruit, and sugar content were significantly different. Keywords: applications agriculture environmentally-friendly, strawberry fruit quality

Abstract

This study aims to determine whether there is an interaction and influence of concentration from the administration of Trichoderma sp. and Plant Growth Promoting Rhizobacteria (PGPR) on the root growth of chrysanthemum plants. This research was carried out at the Center for Protection and Quality Testing of Horticultural Food Crops and the Screen House Office of the Center for Seeds, Agricultural Nurseries and Agrotourism Show Window, Tomohon City. This research was conducted from June to August 2022. Primary data was obtained from the results of the study including the variables root length, root weight, and percentage of living cuttings while secondary data was obtained through books obtained from local bookstores and the internet via Google Scholar in the form of books, articles journals and theses related to research topics. The results showed that the longest plant roots were produced at the concentration level of Trichoderma sp. solubility of 107 and PGPR 15ml/l (T1P3) with an average of 11.6 cm and the heaviest roots were produced at the concentration level of Trichoderma sp. solubility 109 and PGPR 10ml/l (T3P2) with an average of 0.49 gram.

Abstract

Sweetleaf stevia (Stevia rebaudiana Bertoni) is one of the potential sugar-producing plants besides sugar cane which is widely used as a natural non-calorie sweetener. Propagation of stevia by shoot cuttings produces more uniform seedlings. Plant Growth Promoting Rhizobacteria (PGPR) contains a group of beneficial bacteria that live in the plant root ecosystem that can stimulate plant growth. This study aims to determine the effect of PGPR on the growth of stevia cuttings and the best concentration of PGPR on the growth of stevia cuttings. This study was conducted in February-May 2024 in Kolongan Atas II Village, Sonder District, Minahasa Regency, North Sulawesi Province. The study used a Completely Randomized Design (RAL), with 5 treatment levels, namely P0 = Control (Without PGPR), P1 = PGPR 10 ml/liter of water, P2 = PGPR 20 ml/liter of water, P3 = PGPR 30 ml/liter of water and P4 = PGPR 40 ml/liter of water. Each treatment was repeated 4 times.The results showed that the aplication of PGPR affected the growth of stevia cuttings. The best PGPR concentration for the growth of stevia cuttings was at a PGPR treatment concentration of 20 ml/liter of water.  Keywords: plant growth promoting rhizobacteria, stevia
