Abstract

Shallot is a horticultural commodity that has high economic value and has good market prospects because it contains high nutrition and can be used as spices and ingredients for traditional medicine. However, shallot production in Indonesia still often fluctuates and even experiences a shortage in meeting the needs of domestic consumers. To increase shallot production, this can be done through intensification efforts, namely by improving cultivation techniques, including the use of organic fertilizers, proper fertilization, and the use of superior varieties. This study used a factorial randomized block design consisting of 2 treatment factors, namely factor I was fermented NPK (F) consisting of 0 ml, 250 ml, 500 ml and 750 ml. Factor II was the variety (V) of the Brebes Bima variety, the Probolinggo variety and the Nganjuk variety. The data analysis method was a factorial randomized block design (RBD). The results showed that the application of fermented NPK and the use of varieties had a very significant effect on the number of tillers per clump (saplings), production per sample (g), production per plot (g), tuber diameter (mm).Keywords: shallots, NPK fermented products, variety

Abstract

Budidaya kakao diindonesia umumnya petani masih menggunakan teknik tradisional,  Hal tersebut juga diiringi minimnya inovasi dan teknologi pada budidaya kakao sehingga banyak sekali pohon kakao kurang terawat dengan baik. Permasalahan budidaya kakao biasanya karena kurangnya pemanfaatan teknologi produksi kakao tidak optimal dan penggunaan bahan tanam yang tidak jelas asalnya, Petani juga kurang melakukan pemupukan yang sesuai aturan, dan kurang dalam perawatan, sehingga serangan organisme pengganggu tanaman meningkat Penggunaan pupuk kimia tidak sesuai dengan anjuran, mengakibatkan kualitas dan kesuburan tanah menurun. Solusi untuk mengurangi pemakaian pupuk anorganik adalah memanfaatkan bahan organik yang berasal dari tanah akar bambu dan mikroorganisme sebagai pupuk hayati. Bakteri akan meningkatkan mekanisme pertumbuhan biomassa akar. Isolat bakteri rizosfer diperoleh dari sekitar akar tanaman bambu. Tujuan dari penelitian ini adalah Untuk mengetahui respon pertumbuhan tanaman kakao (Theobroma cacao L.), pada perendaman dan pemeberian microkapsul bakteri rizosfer dengan taraf perlakuan yang bervariasi. Desain penelitian yang digunakan adalah Rancangan Acak Lengkap (RAL), 16 perlakuan dan 2 ulangan. Faktor pertama adalah perendaman biji kakao menggunakan suspensi bakteri rhizosfer yang terdiri dari A0=0 jam; A1= 8 jam; A2=16jam dan A3= 32 jam dan faktor kedua adalah penambahan mikrokapsul yang terdiri dari C0= 0 gr; C1=10 gram; C2= 20 gr; C3= 30 gram. Isolasi dari akar dan batang kakao diperoleh 9 isolat bakteri rhizosfer.

Abstract

Tea (Camellia sinensis L), is a popular agricultural product enjoyed by people around the world. Bio-fertilizers that use bacteria found in soil called endophytes, have proven effective for increasing growth and plant productivity. Endophite bacteria can also produce growth hormones such as auxins, ethylene, and cytokinins. This research aims to determine the effectiveness of auxin-producing endophytic bacterial microcapsules on tea growth. The research design used was a completely randomized design (CRD), 16 treatments with 2 replications. The first factor was immersion of  endophite bacterial suspension consisting of S0 = 0 hours; S1 = 24 hours; S2 = 36 hours and S3 = 48 hours and the second factor was the addition of microcapsules consisting of I0 = 0 gr; I1 = 5 gr; I2 = 10 gr; I3 = 15 gr. Isolation from tea roots and stems obtained 6 isolates of endophite  bacteria. Auxin test showed that the six isolates were able to produce auxin. Observation of plant height showed that the best treatment was in treatment I3 (17.04 cm). Observation of leaves amount was in treatment I3 (6.88 strands). For the leaf area parameter, the highest number was in the S1 treatment (22.8 cm2). For stem diameter parameter, highest data was in treatment I2 (1.69 mm). The test results showed that the application of suspension and endophite bacteria microcapsules  significantly increased the growth of tea.

Abstract

The growth of coffee (Coffea arabica L) plants is highly dependent on the quality of the seeds and fertilization. One of the newest innovations in the field of organic farming is the use of endophytic bacteria as potential candidates to be developed become biofertilizers. Endophytic bacteria that produce IAA (Indole acetic acid) are able to produce phytohormones that can accelerate plant growth. The purpose of this researeh was to determine the effectiveness of endophytic bacterial microcapsules for the growth of Arabica coffee plants. This research was conducted using the factorial CRD (Completely Randomized Design) method consisting of 2 factors, 16 treatments, 2 replications. The first factor was  immersion  of endophytic bacterial suspension consisting of B0: without immersion; B1:8 hours; B2 :9 hours;  B3: 10 hours.  Microcapsules addition of endophytic bacteria consisting of I0 : 0 gr; I1 : 5 gr; I2 : 10 gr; I3 : 15 gr. The results from isolation was obtained four isolates of endophytic bacteria. The IAA test showed that the four  isolates were able to produce IAA. Observation of plant height showed that the best treatment was treatment B1 of (16.31 cm). Observation on total of leaves, best treatment were B1 and B2 (10.57 strands). For the leaf area parameter, the best treatment was B3 of (27.36 cm2). Test results showed that application of suspension and microcapsules of endophytic bacteria significantly increased growth of coffee

Abstract

Cocoa (Theobroma cacao L.) is one of the main plantation commodities which plays an important role in the Indonesian economy, and 3rd ranked in the world for cocoa producers. One effort to increase cocoa productivity was the use of biological fertilizer. The aim of this research was to determine the effect of using rhizosphere bacterial microcapsules as biofertilizer on the vegetative growth of cocoa leaves. The research design used was a Completely Randomized Design, with two factors, the first was immersion the cocoa beans using a rhizosphere bacterial suspension consisting of A0=0 hours; A1= 8 hours; A2=16 hours and A3=32 hours and the second factor is the addition of microcapsules consisting of C0=0 gram( g ); C1=10gr, C2=20gr, C3=30gr. Combination The treatment was repeated twice so that 32 plants were obtained. For the parameter of observing the number of leaves, the best results were shown in the 8 hour immersion treatment with an average number of leaves of 12.63, followed by the treatment of giving 20 grams of capsules with an average number of leaves of 11.75. The lowest number of leaves was shown in the 16-hour and 32-hour immersion treatments at 10.75. Meanwhile, for the observation parameters of leaf area, the best results were shown in the 32 hour immersion treatment with an average leaf area of 73.49 cm 2 and the lowest results were shown in the non-immersion treatment with an average leaf area of 59.88 cm 2 . The results of the analysis of variance showed that all treatments had no significant effect

Abstract

The aim of this research is to determine the application of quail manure fertilizer and vegetable waste POC in increasing soil fertility on grape plant cuttings (vitis vinifera) in the pre-nursery and their interactions. This research used a factorial randomized block design (RAK) consisting of 2 factors with 12 treatment combinations and 3 replications so that 36 plots were needed in the study. The factor studied was the treatment of quail manure fertilizer which consisted of N0= 0 g/plot, N1 = 400 g/plot, N2 = 800 g/plot, N3 = 1200 g/plot. Factor II treatment of giving POC vegetable waste consists of A0 = 0 mL/liter of water/plot, A1 = 5 mL/liter of water/plot, A2 = 10 mL/liter of water/plot. The parameters observed are plant height, length of tendrils, number of leaves, number of stem segments, stem diameter and number of tendrils. The results of the research showed that the application of quail droppings showed no significant effect on the parameters namely plant height, vine length and stem diameter but had a significant effect on the treatment of the number of leaves, number of stem segments and number of vines. The provision of POC vegetable waste showed no significant effect on plant height, tendril length, number of stem segments, stem diameter and number of tendrils. But it has a real effect on the number of leaves. Key words: planting media, eggshell liquid organic fertilizer, grape plants INTISARITujuan penelitian ini adalah untuk mengetahui pemberian pupuk kotoran burung puyuh dan POC limbah Sayuran dalam peningkatan kesuburan tanah pada stek tanaman anggur (vitis vinifera) di pre nursery berserta  interaksinya.
