In order to obtain an effective and efficient control method in integrated pest management, a research to know the effectiveness of combination treatments on Empoasca sp. on tea plant had been conducted. The trial was carried out at Gambung Experimental Station (1,250 masl) and designed in Randomized Complete Block design (RCB), with 8 treatments and 3 replications. The treatment tested comprised with A. Paecilomyces fumosoroseus (Pfr); B. sticky trap (ST); C. imidacloprid (I); D. Pfr + ST; E. Pfr + I; F. ST + I; G. Pfr + ST + I; and H. control. Pfr multiplied in rice medium 2.5 kg ha-1 and imidacloprid 0.125 L ha-1 were sprayed, while sticky trap was set in the middle of 5 m x 5 m plot. The parameters observed were attack intensity of Empoasca sp., population of Empoasca sp, and tea shoot production. The results showed that after 3 times application of all treatments revealed a decrease in the attack intensity of Empoasca sp. After the fourth application, combination treatment of sticky trap (ST) + imidacloprid (I) consistently showed higher efficacy than other treatments. In the sixth observation, the average of Empoasca sp. attack intensity of combination treatment (ST + I) was 15.95% with an average population of 0.67 Empoasca sp. per plot. In the meantime, tea shoot production was 33.64% higher compared with control.

Tea Shoot roller (Cydia leucostoma Meyrick) is one potential pests that attack tea shoot, mainly on the new tea shoot after prunning, it caused plant growth becomes stunted. One of control that can be done is by application of insecticides. To determine the effectiveness of insecticide Acetamiprid, the trial has been conducted at Block A7, Gambung field trial, Kabupaten Bandung, during ± 3 months, from October up to December 2016. The trial was designed in Randomized Complete Block Design (RCBD) with five treatments and four replications. The treatment tested covered insecticide Asetamiprid 30% at 1; 0.75; 0.50; 0.25 l/ha and control. The insecticide was sprayed six times using knapsack sprayer one day after plucking, with one week interval. Tea shoot roller attack intensity was observed weekly at the time of plucking. Shoot production, phytotoxicity, as well as rainfall were also observed as a supporting data. The results showed that after three times of spraying, insecticide Asetamiprid 30% at all formulation doses tested could effectively suppress the attack intensity of tea shoot roller. The last observation result, after six times spraying, revealed that the average efficacy level relatively high, i.e. 73,24%. Therefore, for controlling tea shoot roller on tea it could be recommended the use of insecticide Asetamiprid 30%.

<em>Zinc deficiency (Zn) in tea </em>[Camellia sinensis<em> (L.) O. Kuntze</em>] <em>may inhibit growth and decreases shoots production. To overcome the deficiency, zinc is generally given in the form of zinc sulphate fertilizer (Zn 22.75%) through foliar application. Today there is a micro-fertilizer with a higher zinc consentration (Zn-30%). The research aimed to determine the effect of dosage and application interval of Zn-30% micro fertilizer on production and yield component of tea shoot. The experiment was conducted in Pasirmalang Estate, Afdeling Wetan Block Pakurendeng II, PT Perkebunan Nusantara VIII Pangalengan Bandung, West Java, altitude ±1,600 m asl, from November 2016 to June 2017. The tea clone used was productive GMB 7. Experiments were designed by randomized block design with 2 factors and 4 replications. The first factor is Zn-30% that consisted of 4 levels i.e. Zn-30% with a dose of 300, 250, and 200 g/ha respectively, and  ZnSO<sub>4</sub> with a dose of 2 kg as control. The second factor is interval of application that consisted of 2 levels, once and twice applications after plucking. Variables observed were production and yield components of tea shoot. The results showed that application of Zn-30% with a dose of 300 g/ha in one time interval of application after plucking effectively increased shoot production compared to other doses, but not significantly different with </em><em>ZnSO<sub>4</sub> in two time interval of application. Application of Zn, either in the form of oxide salt or zinc sulphate, increased the percentage of pecco shoots and reduces number of banji shoots.</em>

This study was conducted in Balai Benih Induk (BBI) Luwus, Baturiti District, Tabanan Regency, with the high of place 506m above sea level occurring in March to May 2014. This research used randomized block design arranged per factor, namely population of plants (P) including three steps: P1=80.000 plants per hectare, P2= 100.00 plants per hectare, P3= 120.000 per hectare; and mulch (M) that include: M0= without mulch and without cleaning, M1= without mulch with clean weeding, M2= rice plants straw mulch (5 ton per hectare) and M3= black silver plastic mulch. Eventually, there were 12 combination treatments, each of which was repeated 3 times to obtain 36 land slots. The research indicates that there was no real interaction between the treatment of plant population and mulch usage in all variables observed. The 100.000 plant population per hectare can produce the weight of dry and fresh oven corn kernel without highest cornhusk that was to say 4.79 tons and 0.53 tons or 11.66 % and 20.45% higher compared to 120.000 plant population per hectare. The use of black silver plastic and rice plants straw mulch can produce the weight of fresh and dry oven corn kernel without cornhusk per hectare each of which is 4.69 tons, 4.57 tons, and 0.54 tons, 0.47 tons or 26.76%, 38.46 %, and 23.51 %, 20.51 % higher than without mulch and without clean weeding. Clean weeding treatment can produce the weight of fresh and dry oven corn kernel without cornhusk per hectare with its weight of 4.63 tons and 0.51 tons or 25.35 % and 35.90 % higher than without mulch and cleaning. Clean weeding treatment was not obviously different from mulch treatment. The identification of weed types were 19 kinds of weeds and Cyperus rotundus L. Weeds. They have the highest density and each absolute frequent of 1249.333 stems m-2 and 1.00.

Cuttings from three southern magnolia cultivars, `Claudia Wannamaker', `Greenback™', and `Little Gem', were treated with KIBA, KNAA, and Hormodin #3, separately and in combination, at varying concentrations. The rooting of cuttings was cultivar-dependent, with `Greenback™' responding significantly to all the treatments. Only the high KNAA and combination treatments were effective with `Little Gem' and `Claudia Wannamaker'. The effect of KNAA on rooting with increasing concentration was significant. No similar response was observed with KIBA. The combination treatment with quick dip plus the talc formation produced the greatest rooting and root quality with the three cultivars. With this treatment, the average rooting rate of three cultivars was 67.4%, whereas the rooting rate of control plants was only 11.8%.

Papaya is a popular fruit and is grown commercially in many subtropical and tropical countries. Papayas are generally grown from seeds; therefore the offsprings are not true-to-type and could come in three sexes, female, male, and hermaphrodite. Clonal propagation is required to obtain to grow true-to-type hermaphrodite papayas. In this research, we developed an in vitro protocol for shoot multiplication from lateral shoots from in vitro germinated papaya seedlings. The in vitro propagated plant materials could potentially be used as a source of papaya micro cuttings, or as scion for papaya grafting. The experiment was set up as a factorial experiment with NAA at 0, 0.1 and 0.5 mg.L-1, and BAP at 0, 0.1, 0.5, and 1.0 mg.L-1 in a completely randomized block design. BAP interacted with NAA in affecting the shoot production per explant. The optimum BAP and NAA concentration to produce lateral shoots was 0.54 mg. L-1 and 0.1 mg.L-1, respectively. Media without NAA reduced the number of lateral shoots and number of leaf per explant at any BAP concentration.Keywords: hermaphrodite, seeds, true to type, clonal propagation, micro cuttings.

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), weight of banji and pekoe (g/100g) 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) compared to other treatments.

   Pakcoy is a type of mustard plant that is quite popular with the community, it is very suitable to be cultivated considering the need for vegetables is quite large. The community's need for fresh and pesticide-free vegetables is a choice now in line with the community's understanding of a healthy diet. Alternatives to fulfillment are chosen by planting with hydroponic media. Hydroponics is a substitute for soil media that can be used to grow vegetable crops. The presence of hydroponics is expected to be able to overcome the narrowing of agricultural land and reduce the use of pesticides considering that pesticides greatly affect human health and the environment.   This study aims to determine the effect of nutritional doses of AB mix agrifarm and age of seedlings and their interactions on the growth and yield of pakcoy plants, this study is carried out in the experimental garden of the Faculty of Agriculture, Tabanan University which began on 9 December 2018 until 12 January 2019.   The study used a Randomized Block Design (RBD) consisting of two factors. The first factor is the nutritional dose of AB mix agrifarm (N) which consists of three dose levels, namely the dose of 850 ppm, 1050 ppm and 1250 ppm. The second factor is the age of seedlings (U) which consists of two seedling age levels, namely the age of seedlings 1 week and 2 weeks. Each treatment is repeated four times.   The results of the study obtained the interaction of dose agrifarm treatment with seed age showed a very significant effect (p 1 0.01) on all parameters except for the parameters of the number of leaves aged 35 days old which showed no significant effect (p 5 0.05). The economical wet weight of plant-1 and BKO of the highest yield of 1-crop yield is produced in the combination treatment of N3U, which amounted to respectively 244.09 g and 78.10g or increased respectively by 57.78% and 293.85% compared to results the lowest produced by the combination treatment of N1U1 is 154.71g and 19.83g
