The Influence of Mineral-Based Compound Fertilizer (CFC) on the Health and Production of Tea Plant Clone GMB 7

Abstract

Tea is a commodity that has a significant contribution to Indonesia's foreign exchange, especially from non-oil and gas sectors. Fertilization is one of the important factors to produce high productivity and keep the plant healthy. The healthy plants are simply indicated by the ratio of pecco and banji more than 2.33. This research aimed to test the effect of Mineral-Based Compound Fertilizer (CFC) on a plant health and tea plant productivity. The research was carried out in April-October 2014 at the Gambung Experimental Station, Block B6, Research Institute for Tea and Chincona by using CFC with a composition of 80% Mineral Compound Fertilizer, 10% urea, and 10% KCl. The experiments used a Randomize Blocked Design with four replications and six treatments; i.e. 120% CFC tekMIRA; 100% CFC tekMIRA; 80% CFC tekMIRA; 60% CFC tekMIRA; NPK (25:7:12:3) as control compound fertilizer; and single standard fertilizer. The result showed that all of the treatments did not increase the plant health. However, the application of CFC produced a higher tea plant productivity compared to NPK (25:7:12:3) as control compound fertilizer and single standard fertilizer. Based on regression equation, the dose of CFC that produced the optimal tea productivity was 93.92%.

Bio-organo mineral effect on soil fertility, nutrient uptake, and sweet corn (Zea mays L. saccharata) growth planted in inceptisols soils

“…209/KPTS/SR.320/3/2018 (Laboratorium Kimia UNPAD, 2021). This fertilizer has been tested for tea, rice, and sweet corn plants with satisfactory results in terms of growth and production (Pranoto, Saleh and Wulansari, 2018;Wulansari et al, 2021).…”

Growth and production of tea plant (Camellia sinensis (L.) O Kuntze) after pruning with bio-organomineral ameliorant

“…Research and Development Center for Mineral and Coal Technology (tekMIRA) is one of the competent institutions in the field of mineral and coal research. Several minerals have potential for agriculture as a nutrient source needed by plants such as cassiterite, pyrolusite, psilomelan, braunite, manganit, feldspar, and zircon (Pranoto, Saleh and Wulansari, 2018). Bio-organomineral ameliorant (BIOM) is an ameliorant that combines mineral, organic and beneficial microorganisms produced by tekMIRA and the Tea and Cinchona Research Center.…”

“…In addition. Based on Pranoto, Saleh and Wulansari (2018) the BIOM application produced the optimal productivity of tea clone GMB 7 on three years after pruning around 93.92% and had highest production in the rainy season and the highest pekoe weight indicate the healthy of tea plant. It was reported also that the organomineral fertilizer treatments significantly increased the plant growth and development, thus the yields in tomatoes as compared to mineral fertilizers applied at the same quantities (Ayeni and Ezeh, 2017).…”
