Growth and Yields of Sorghum Local (Sorghum Bicolor L.)
Authors: Stefania Kolo
Pages: 36 - 39
Abstract: An experiment was carried out using the type of manure and frequency of watering PGPR to increase the productivity and yield of sorghum plants (Sorghum bicolor L.). The research aims to determine the impact of growth and production of sorghum (Sorghum bicolor L.). By using the type of manure and frequency of PGPR irrigation. This research was conducted in the experimental garden of the Faculty of Agriculture, University of Timor, in January-April 2019, the design used was a factorial randomized 3x3x3 randomized block design with 3 replications. The first factor is the type of Manure (K) namely: Without Cow Manure (K0), Cow Manure (K1), Goat Manure (K2). The second factor is the frequency of watering PGPR (F) namely: Without watering PGPR (F0), twice watering (F1), three times watering (F2). Variance results (Anova) showed that without the administration of types of manure and without the frequency of watering PGPR interacted positively (P <0.05) in influencing the value of the harvest index. The main effect of single factor type of goat manure on average shows the best results that can be expressed in the form (lowest soil temperature, moisture content 42 and 180 HST highest, plant height 15, 45 and 75 HST highest, highest number of leaves 45 HST, stem diameter 45 of the largest HST, the heaviest dry weight per plant, the heaviest dry weight of 1000 seeds, the heaviest seed dry weight population, the lowest disease severity and the heaviest stover dry weight while the single factor of PGPR watering frequency did not show any significant difference between treatment levels.

- Effect of Combusting Temperature Biochar of Kayu Putih (Eucalyptus alba)
And Frequency of Watering Tea Compost on Growth and Products of Land
Lettuce (Lactuca saiva L.) On Vertisol Soil
Authors: Aplonia Mau
Pages: 40 - 44
Abstract: Soil type in dry land, dominated by vertisol soil. Vertisol soil is a soil with a high klein content and has the characteristic of expanding and contracting periodically, which expands when wet and contracts when dry. Due to the nature of the soil, it is necessary to use soil amendments to increase soil aggregation and aeration so that the absorption of water in the subsurface layer of the vertisol soil is maximized. Shallow and fine lettuce roots require better aggregation and aeration of vertisol soil. This study aims to determine the effect of burning temperature for kayu putih (eucalypus alba) biochar and the frequency of giving compost tea on the growth and yield of lettuce (Lactuca sativa L.) on vertisol soil. This research is a field experiment carried out from March to May 2019 in the experimental garden of the Faculty of Agriculture, University of Timor, Kota Kefamenanu District, Sasi Village, Timor Tengah Utara Regency. This study uses a completely randomized design (CRD) with 2 factorials with the first factor being the combustion temperature of the biochar raw material which consists of 3 levels, namely 350ºC, 450ºC and 550ºC. The second factor is the frequency of watering of tea compost which consists of no compost tea, one watering a week, 2 watering a week and 3 watering a week. So that in this study there were 12 experimental units which were repeated 5 times. The results showed that the combination of biochar combustion temperature treatment and watering frequency of tea compost significantly affected the observation of plant height at 35 days after planting, number of leaves at 35 days after planting, and total plant fresh weight. Kayu putih (eucalypus alba) biochar which was charred at 350ºC gave the best effect on the growth and yield of lettuce. The frequency of watering compost tea once a week gave the best results on the growth and yield of lettuce (Lactuca sativa L.).

- Identification Fungal Pathogens of Several Seed Varieties Peanut (Arachis
hypogaea L.) Different Storage Places in Insana Barat District
Authors: Yunita Alberta Kono
Pages: 45 - 48
Abstract: This study aims to identify the patogenic fungi of peanut seeds in several storage areas in the West Insana District and obtain an appropriate storage place for peanut seeds. The study was conducted at the Laboratory of the Faculty of Agriculture, University of Timor, East Nusa Tenggara, in February-March 2020. The design used in this study was to use a completely randomized design (RAL) with 2 factorial. The first factor is the storage area (P) consists of 3 levels, namely: plastic sacks (P1), socal (P2), cans (P3). The second factor is the type of variety (V) consisting of 3 arsas, namely local red peanuts (V1), local white peanuts (V2), and striated peanuts (V3). Each treatment combination was repeated three times so that there were 27 experimental units. Based on the results of the study, there were 4 contaminant fungi contaminating peanut seeds including fusarium sp, Aspergilus sp, Melanospora sp, and Rhizopus sp. Canned storage models and striated peanut varieties provide the lowest patogenic insects when storing. Testing the viability of peanut seeds on the maximum maximum growth potential parameters there are peanut seeds from the storage model with a percentage of 91.56%, germination capacity in storage with a percentage of 90.22%, and a vigor index 85.78% higher from the storage model in the sack.

- Effects of Compost and A Dose of Compost Tea on The Growth and
Productivity of The Mustard (Brassica juncea L.) in The Dray Land of
Entisol

Abstract: The study aims to know the effects of compost onthe growth and productivity of mustard plants (Brassicajuncea L.) and toknowhowadoseofcompostteaeffectgrowthand productivity of the mustard. Thestudywascarried out in September and October of 2020 in the opposition of daughter Kimbana BTN, South Bikomi District, City Kefamenanu, North Central Timor (TTU). The research design used is a complete random design (CRD) of two distinct factors. The first factor compost consisting of thre cedars without compost as control, postfif teen ton/acresare, compost twenty five tons/acres are. These cond factoris a three-aras doseofcompost and compost tea two, compost five millits.The observed variable compost tea in general donot showthe effect of interactions on all observations.The sole impact of compost measure twenty five tons/acres are shows fresh, non-econimical data of the tallest plant real difference between the cedar’streatment. Compost tea two,fivemilli compost effects optimally increases growth and produce plants that are properly expressing with the freshet weigth of the tallest tatal plant, the higthest fresh weight.

- Study of Some Physical Properties of Entisol Soil Containing Biochar and
Compost Residence in Corn Sari (Zea mays L.) and Rice Nut (Vigna angularis
L.)
Authors: Maria Krisanti Moru
Pages: 54 - 56
Abstract: The purpose of this study is to identify some of the physical properties of the entisol ground that contain biochar residue on the corn cider (Zeamays L.) and rice beans (Vigna Angularis L.) and to identify the most optimal types of biochar and compost residue on some of the entisol’s properties by containing the biochar and compos residue on the corn (Zeamays L) and rice beens (Vign a Angularis L.) the study carried out in july 2020-september 2020 on the agricultural farm, Timor university kefamenanu – Timor Tengah Utara. The design used in research is a random grouping of two vectored areas. The first factor is the biochar residue consisting of four cedars, which is without biochar, 5 tons/acre wheat chaff, five tons/ acre are biochar, five tons/acre views, biochar kerinyu 5 tons/ acre wheat, the second factor of compost residu consist of two levels without compost, 0 tons/acre are, compost ten tons/acres are. There’s an interaction between duchar and residue compost residual treatment on final ground temperature observations. The biochar sakam rice residue is capable of optimize the physical properties of the soil as shown by highest density of the original soil and the lowest volume of soil. Though it does not make a noticeable impact between treatment, the compost residue does increase the physical quality of the soil.
