Abstract

The study was conducted at the Jatikerto village, Sumber Pucung sub-district, Malang regency The Randomised Block Design was used in this experiment and each treatment was replicated twice. The study used erosion plots ( 12 x 10 ) m , with a slope of 8 % , maize ( 1 0 X 04 ) m and cassava ( 16 ) x1.0) m inter-cropped as the main crops. The plants used for the strip were gajah grass, raja grass taiwan grass, vetiver grass, benggala grass at (0.15 x 6.0) m planting distance, and Gliricidia, with seed and stump at (0.20 x 6.0) m planting distance. The result shows, soil water usage indicate that evapo-transpiration of all treatments ranged from 876 mm (4.02 mm day) to 899 mm (4.13 mim day ). There was no significant difference of soil water content at 25 cm, 50 cm and 150 cm distance from the strip but otherwise was shown by the increase of the depth of the soil

Abstract

ABSTRACTIndonesia imported very high amount of date palm fruits about US$ 13,18 M, because of that it is necessary to develop a research about date palm nursary and investigation of female date, since this is a deciduos plant.  The research used plastic pots for nursary and the age of nursary were 15 and 30 days and the addition of compost and without compot during nursary.  Then 30 days old date palm was planted in a bigger pot and covered using coconut palm leaves for female investigation after 30 days planting.  Seedling at the age of 15 and 30 days planted in the polybag for monitoring the growth ability of plant.  Results showed the characteristics of a female crop was curly new growing root and curly first leaf, where curly root occured on 15 days old of nursary.  Thus female investigation could be done at the age of 15 days and without waiting for the first leaf growing.  Compost was very important on increasing roots and leaves growing of seedling at the age of seedling 30 days and which had one leaf had the ability to grow about 90%.  It is needed further investigation on this female date palm can produce fruit and it will take up to 3 years for fruiting.

Abstract

The research was conducted to study the effect of storage condition and osmoconditioning treatment on the viability of gmelina seed. The experiment was designed as a factorial experiment in a completely randomized design. The factors studied were storage condition (K), and osmoconditioning treatment (c). storage condition consist of room temperature condition (28-32oC) (K1) and under aircondition temperature (K2), where as osmoconditioning treatment consist of control (Co), PEG 0,4 MPa (C1), PEG 0,8 MPa (C2), KNO3 0,5 MPa (Ca3) and KNO3 0,1 MPa (C4). Observation was carried out in beweekly basis during sixteen weeks storage periods. The parameters observed were potential viability, growth strength vigour, and rate of metabolic activity changes. The research results showed the osmoconditioning treatment using PEG 0,4 and 0,8 MPa significantly increase total normal seedling. Moreover, osmoconditioning treatment using KNO3 0,5 MPa, and 1,0 MPa in the condition at under air conditioner room increase free fatty acid of the storage seed.

Abstract

Toxicity of enthomopathogenic fungi Beauveria bassiana to armyworm (Spodoptera litura) has been investigated in Pest Laboratory of Faculty of Agriculture, Syiah Kuala University, Darussalam, Banda Aceh. This research was aimed at determining lethal concentration (LC50) and lethal time (LT50) of B. bassiana suspensions against third instar larvae of armyworm. The fungi concentration used was in the range 0-6 % (w/v) or equal to 9,33 x 106 – 45,83 x 106 conidia/ml. The fungi suspension was applied to the larvae by dissolving the larvae into the suspension for 10 seconds. The number of the larvae died and the time required to kill the larvae were recorded everyday starting one day after application (DAA) until pupation. The relation between each observation to the fungi concentration was analyzed using probit analysis. The result showed that B. bassiana suspension caused the death of the larvae beginning 4 DAA with maximum eath on 10 DAA. The death of the larvae caused by the growth and the development of the fungi inside the larvae. The LC50 of the fungi suspension against the larvae was 3,57 % while the LT50 at 4, 5, and 6 % fungi concentration were 9,88; 8,13; and 6,8 days respectively.

Abstract

Mn2+ sangat larut di dalam system aquatic dimana prinsip kultur larutan adalah sama dengan system akuatik. Dua set eksperimen mengenai pengaruh konsentrasi Mn2+  di dalam kultur larutan terhadap pertumbuhan tanaman telah dilakukan di rumah kaca University Putra Malaysia, Serdang, Selangor, Malaysia. Studi ini bertujuan untuk mengetahui konsentrasi toksik Mn2+  di dalam kultur larutan pada pertumbuhan tanaman. Sebagai tanaman indicator adalah “vegetable soybean” (Glycine max L.) Pada eksperimen pertama menunjukkan 60 µM Mn berkesan sangat toksik pada pertumbuhan tanaman, sementara pada eksperimen kedua menunjukkan bahwa 7.5 µM adalah optimum. Penurunan berat kering daun, akar dan batang tanaman soybean sangat nyata pada taraf 37.5 µM. Ianya disebabkan oleh pengurangan luas daun dan panjang akar dengan penambahan konsentrasi Mn2+ pada kultur larutan.

Abstract

Abstract This study was to determine the effect of adding several types of organic fertilizers to the nursery media for coffee plants. It is expected that data will be obtained that can describe the growth of coffee plant seeds (Coffee sp) well so that superior coffee plant seeds will be produced. The method used was an experimental method using a non factorial randomized block design consisting of 4 planting media treatments that were repeated 3 times. As a growing medium used land (M0); soil + vermicompost (M1); soil + quail dung (M2) and soil + biochar (M3). The parameters observed were, wet weight and dry weight of the plant and root canopy ratio. The nursery was carried out for 5 months. In the parameters of wet weight and plant dry weight analysis of variance showed that media treatment had a very significant effect, namely on the M1 treatment. Whereas the root canopy ratio parameters did not show any effect, although the M1 treatment tended to show the lowest root canopy ratio, which means that the seedlings of this plant had an indication of a better root system.

Abstract

Ageratum conyzoides L. merupakan gulma yang tumbuh tegak dengan batang bagian bawah berbaring. Tinggi tumbuhan ini sekitar 30-90 cm dan bercabang. A. conyzoides mengandung senyawa metabolit sekunder meliputi flavonoid, alkaloid, kumarin, minyak esensial dan tannin. Ekstrak metabolit tanaman ini telah ditemukan memiliki aktivitas bioherbisida. Daun A. conyzoides diekstraksi secara maserasi menggunakan pelarut metanol. Ekstrak metanol yang diperoleh di rotary evaporator dan menghasilkan ekstrak methanol pekat dengan beberapa konsentrasi yang akan diaplikasikan pada gulma sasaran untuk melihat aktivitas penekananya. Hasil uji menunjukan bahwa konsentrasi 20% mampu menekan pertumbuhan bayam duri, dan penggunaan pelarut turut mempengaruhi senyawa yang diekstrak dari tanaman tersebut. The activity of bioherbisida extract methanol of babadotan (Ageratum conyzoides) on the growth of Bayam Duri (Amaranthus spinosus)Ageratum conyzoides L. Is weed that grows erect with the stem the bottom lying. High herbs this is about 30-90 cm and branching. A. conyzoides compound containing a metabolite secondary covering flavonoid, an alkaloid, coumarin, essential oils and tannin. Extract of a metabolite these plants have been found the bioherbisida activity. Leaves A. conyzoides extracted in maceration use methanol solvent. Extract methanol obtained in rotary evaporators and yielding extract methanol out of some concentration will apply to weed objective to see activity his emphasis. Test results showed that concentration 20 % able to press spinach spines growth, and the use of a solvent also influence compound extracted from the plant.
