Changes of Composition and Amount of Volatile Compounds in Green Tea about Organic Fertilizer and Plucking Seasons

Tea shoots processing intended to alter the chemical composition of fresh tea shoots, so bring the desired properties. Freshly plucked tea leaves containing water 75% of the weight of the leaves. The water contained in the leaves removed through the process of withering and drying in the processing of green tea. Green tea liquid waste obtained from the milling process and not used optimally, it needs a touch technology that can turn liquid waste into useful liquid organic fertilizer. The use of an activator / starter (micro-organisms) in green tea liquid waste is an alternative technology to improve the health and fertility of the soil and plants. The purpose of this study to determine the benefits of using liquid waste of green tea on the growth of tea seeds. Results of analysis of the utilization liquid waste of green tea with the addition of starter (EM-4) has not shown any real effect on the percentage of seedling growth and seedling growth (plant height, number of leaves and greenery). Keywords: liquid waste, green tea, organic matter.

ABSTRACT This research aimed to know the differences influence the frequency of watering fermentation liquid waste green tea on early growth of rubber plant seed. This research method using Randomized Complete Block Design (RCBD) non factorial, i.e. the granting of fermentation liquid waste green tea with a dose of 10 ml/poly bag with 3 treatment. As for the extent of the treatments given are control (P0), the frequency of watering every two weeks (P2), the frequency of watering every four weeks (P4). Each treatment was repeated five times so that there are 15 units of the experiment. Each unit is comprised of 1 trial crops so that there is a total of 15 plants. The giving of liquid organic fertilizer from waste liquid fermented green tea can enhance plant growth include rubber, i.e. plant height, number of leaves, green leaves, heavy wet and dry long & root plant rubber. On treatment of P2 (the frequency of watering every two weeks) show the highest results and good than P0 treatment (control) and P4 (the frequency of watering every four weeks). Keywords: fermentation, tea liquid waste, liquid organic fertilizer.

Controlled Release Fertilizers

A field experiment was conducted for 2 years in Green Tea Laboratory of Saitama Prefectural Agriculture and Forestry Research Center, Iruma, Saitama, Japan from March 2014 to December 2015. Controlled release fertilizers (CRF) or organic fertilizers (ORG) which is the mixture of chicken manure and oil cakewere applied with the amount of 450 kg N ha-1 yr-1 in 2014 and 397 kg N ha-1 yr-1 in 2015. Nitrous oxide (N2O) emissionsfrom soil in green tea fields were measured by closed chamber method. The results showed that CRF has significantly lower N2O compared to ORG. The cumulative N2O emissions from CRF accounted for 51% of N2O emissions from ORG fields and 138% of control with no fertilizer treatment. The N2O flux from the row was higher than that of under the canopy, since fertilizer were applied on the row. However the total emission from the area between the rows was lower than that under the canopy because of the area ratio of row and canopy was 1:5.
