Abstract

Tea is a plant that benefits for health. The growth of tea plant was influenced by several factors, including superior clones and nutrient availability in soil. One of the most important macro nutrients is potassium. However, the availability of potassium is low because of retention on the soil. One of the methode for absorbed by plant was used Potassium Solubilizing Bacteria (PSB) with its organic acid function. The aim of the study was to explore and determine the density of colonies (DC) and the potential of Tea Indigenous PSB. Inoculum source from tea rhizosphere and rhizoplan of GMB 7, GMB 9 and TRI 2024 clones. The experimental design used was completely randomized design with six treatments and four replications, i.e. : GMB 7 Rhizosphere; GMB 7 Rhizoplan; GMB 9 Rhizosphere; GMB 9 Rhizoplan; TRI 2024 Rhizosphere; and TRI 2024 Rhizoplan. Ten isolates with the highest halozone was tested by the Dissolution Index (DI) of the PSB. The result showed that the highest DC was GMB 9 rhizoplan by 10.9 x 105 CFU/g and the lowest was TRI 2024 rhizoplant by 3.1 x 105 CFU/g. The DC on GMB clones series showed that rhizoplan was 14,29% higher than rhizosphere. There is no significant difference of DI for PSB colonies from all clones. From that clones, we were obtained 10 isolat that have the highest halozone, that were 2 isolates from rhizosphere and 8 isolates from rhizoplan. The average of DI rhizosphere isolates was 119,9% higher than rhizoplan.

Abstract

Input factor is one of the determinator the quality and response of the tea plant growth. Inorganic fertilizer input still dominates in Indonesian plantations due to the lack of comprehensive evaluation of organic fertilizers, especially in liquid form. This study aims to determine the effect of inorganic and organic liquid fertilizer applications and the frequency of their application on the growth of tea plants. The experiment was carried out based on a Randomized Block Design (RBD) consisting of six treatment combinations, including tap water application once a week, tap water once every two weeks, 1% urea once a week, 1% urea every two weeks, 1% POC once a week and 1% POC once every two weeks. Experiments were carried out on yielding tea plants with the 3rd year of pruning stage. The parameters observed were shoot production (kg.plot-1), weight of banji and pekoe (g.100g-1) and the ratio of banji/pekoe. The results showed that the application of urea foliar fertilizer and liquid organic fertilizer with different application frequencies did not have a significant effect on each observed parameter. Application of 1% liquid organic fertilizer once every two weeks has the potential to increase tea productivity by showing a relatively high production of tea (6.88 kg.plot-1) compared to other treatments.

Abstract

Cabai rawit merupakan komoditi yang memerlukan perawatan dan aplikasi pestisida kimia yang tinggi. Namun, Penggunaan pestisida kimia secara intensif belum sepenuhnya mampu mengatasi permasalahan hama dan penyakit tanaman cabai dan justru berpotensi menimbulkan dampak negatif terhadap lingkungan dan kesehatan. Penelitian ini bertujuan untuk mengkaji pengaruh penerapan teknologi Pengendalian Hama Terpadu (PHT) Biointensif terhadap pertumbuhan vegetatif dan insidensi hama serta penyakit pada tanaman cabai rawit. Penelitian dilaksanakan menggunakan rancangan percobaan komparatif yang membandingkan dua sistem budidaya, yaitu budidaya konvensional dan budidaya dengan PHT Biointensif, masing-masing terdiri atas 30 sampel tanaman. Parameter yang diamati meliputi tinggi tanaman, jumlah daun, serta insidensi penyakit bercak daun dan serangan hama trips dan belalang. Data dianalisis menggunakan uji t tidak berpasangan pada taraf kepercayaan 95%. Hasil penelitian menunjukkan bahwa penerapan PHT Biointensif secara signifikan meningkatkan tinggi tanaman dan jumlah daun pada seluruh waktu pengamatan dibandingkan dengan sistem konvensional. Selain itu, PHT Biointensif mampu menurunkan insidensi penyakit bercak daun dan serangan hama trips, meskipun belum berpengaruh terhadap insidensi serangan belalang. Peningkatan pertumbuhan dan penurunan insidensi hama dan penyakit tersebut diduga berkaitan dengan perbaikan kesehatan tanah, peningkatan aktivitas mikroba bermanfaat, serta terinduksinya ketahanan tanaman. Penerapan PHT Biointensif berpotensi menjadi strategi budidaya cabai rawit yang berkelanjutan dengan mengurangi ketergantungan terhadap input kimia.

Abstract

In tea plantations,  pruning to rejuvenate the plant is regularly carried out. The cutting age that is also known as pruning year determines the estimated production of tea plantations. The land slope is thought to affect the absorption of nutrients, which have implications on yields. This study aimed to explore the interaction between the pruning year and land slopes in nutrients uptake in tea plantations and to obtain the correlation between soil fertility and nutrients content in tea plants at different land slopes. A field experiment was carried out from December 2020 to February 2021 at The Research Centre for Tea and Cinchona, Gambung. A Split Plot design was conducted to observe between pruning year (PY) that consisted of pruning year 1 (PY-1), pruning year 2 (PY-2), pruning year 3 (PY-3) and pruning year 4 (PY-4) with two different slopes in each block that consisted of flat land (slope = 0-8%) and sloping land (slope = 15%-25%). Results of the study showed that there was no interaction between PY and slope on the uptake and nutrient content in the tea plant, but there was an independent effect from each factor, where the PY factor affected all nutrients uptake, while the slope factor only affected P content. There was no significant difference between flat and sloping land on soil nutrients, but there was a correlation between plant nutrients and tea plant nutrient content. P content had a strong correlation with K content (r = 0.657); and K content had a strong correlation with Mg content (r = 0.891).

Abstract

The inorganic fertilizer that is used excessively in tea plantations causes soil health degradation. Tea pruning residue and tea fluff are local biomass that has the potential to be used as alternatives to soil nutrient input that is not well conducted in the tea plantation. This study evaluated biochar from the residue of tea pruning and tea fluff compost as potential organic materials to improve the chemical properties of soil in tea plantations. The tea pruning residue biochar and tea fluff compost were mixed in Inceptisols in a pot experiment with treatment combinations of A = control, B = 2.5 t manure compost/ha, C= 0.25% biochar + 1 t tea fluff compost/ha, D = 0.50% biochar + 1 t tea fluff compost/ha, E= 0.75% biochar + 1 t tea fluff compost /ha, F = 0.25% biochar + 1 t tea fluff compost/ha + 2.5 t manure compost/ha, G = 0.50% biochar + 1 t tea fluff compost/ha + 2.5 t manure compost/ha, and H = 0.75% biochar + 1 t tea fluff compost/ha + 2.5 t manure compost/ha. Soil incubation was conducted for 90 days, and soil samples were analyzed for pH, organic C, available P, exchangeable Mg, and exchangeable K contents. The results showed that the mixture of 0.50% biochar + 1 t tea fluff compost /ha + 2.5 t manure compost/ha gave the most optimal improvement in soil properties. The improvement percentages of soil properties obtained were available P of 334%, Exchangeable Mg of 38%, exchangeable K of 244% and pH of 4.6.
