Published: November 2019

Crocidolomia pavonana (F.) (Lepidoptera: Crambidae) merupakan salah satu hama penting yang dapat menurunkan produksi tanaman kubis-kubisan. Petani umumnya mengendalikan serangan hama ini dengan menggunakan insektisida sintetik. Namun, penggunaan insektisida sintetik yang terus-menerus dan berlebihan dapat menyebabkan dampak negatif pada serangga dan lingkungan seperti terjadinya resistensi dan resurjensi hama serta residu pada produk pertanian. Salah satu strategi alternatif yang dapat dilakukan untuk mengurangi dampak negatif penggunaan insektisida sintetik adalah dengan memanfaatkan insektisida nabati. Penelitian ini dilakukan untuk mengetahui aktivitas ekstrak daun Averrhoa bilimbi, biji Annona squamosa, dan bunga Tithonia diversifolia terhadap mortalitas dan penghambatan pertumbuhan larva C. pavonana. Aktivitas mortalitas diuji dengan ekstrak tunggal dan campuran menggunakan metode residu pada daun. Aktivitas penghambatan pertumbuhan larva C. pavonana juga diuji dengan metode residu pada daun. Ekstrak A. squamosa pada konsentrasi 0.015% dapat mematikan larva C. pavonana sebesar 100% pada pengamatan 72 jam setelah perlakuan (JSP). Sementara itu, ekstrak T. diversifolia pada konsentrasi 5% mampu mematikan 88% larva pada pengamatan 144 JSP. Ekstrak campuran T. diversifolia dan A. squamosa pada rasio 1:1, 1:2, dan 2:1 (w/w) memberikan aktivitas mortalitas rendah. Ketiga ekstrak ini menunjukkan aktivitas penghambatan pertumbuhan terhadap larva C. pavonana.

Authors: Sofian Majesta Esa , Susila Anas Dinurrohman 
Published: November 2019

Cauliflower is one the important vegetable crop in the tropics; the curd contains high fibres, potassium, carotene and vitamin C. However, the production and productivity of cauliflower in Indonesia has been low and cannot meet the demand, resulting in high importation of cauliflowers into Indonesia. Bogor Agricultural University has developed potential lowland cauliflower genotypes, BOB017 and BOB020, with higher productivity. In this study, we evaluated three fertigation methods on the growth, yield and economic returns of the two lowland cauliflower genotypes. The experiment was arranged in a split-plot design with four replications. The main plot contained two cauliflower genotypes, BOB017 and BOB020. The subplot was three fertilizer application methods: through drip irrigation, soil drench, and drilled. The results showed that BOB020 had an earlier harvest time (60 days) compared to BOB017 (71 days). The soil drench fertigation method showed the highest curd weight (351.64 g), curd diameter (14.65 cm) and yield (12.39 t.ha-1) compared to the other two fertigation methods. The BOB017 genotype fertilized with soil drench method resulted in the highest B/C ratio (3.32). The study concluded that growing cauliflower using the soil drench method resulted in the optimum growth of cauliflower, high yield and net income.

Published: November 2019

Spray hose is a micro-irrigation system using perforated hose as for micro irrigation. Shallot conventional cultivation requires lots of water and labor man days therefore is more efficient. Shallot cultivation system needs to be developed to increase yield and to reduce production cost. This research was conducted to compare conventional cultivation methods with using Spray hose and polyethylene mulch for shallot production. This research was conducted in a hydromorphic alluvial soil type at the Center for Tropical Horticulture Studies Field Station in Kersana, Brebes, Central Java (S 6 o, 55’, 20.536”; E 108o, 51”, 50618”) from May to July 2016. The experiment was arranged in a randomized complete block design (RCBD) with a single factor and three levels of planting system, i.e. conventional ‘Surjan’ system without mulch, one line spray hose with mulch, and two lines spray hose with mulch, with five replications. The result showed that shallots production using of polyethylene mulch and two-line spray hose had higher yields than the conventional method. In addition, this system is more efficient in terms of labor requirement. Cost Revenue Analysis shows that conventional cultivation R/C ratio was 1.72, one-line spray hose R/C ratio was 1.92, while two-line spray hose was 2.26. This study demonstrated that the use of polyethylene mulch combined with two-line spray hose significantly improved shallot growth and increased bulb production, and more cost efficient.Keywords: R/C ratio, micro irrigation, labor, ‘Surjan’ system, soil drench, fertilizerConclusionIrrigation of shallot with two-line spray hose resulted in a better crop growth and a higher yield than conventional planting system and one-line spray hose for polyethylene mulched shallot.

Published: November 2019

Nitrogen, phosphorus, and potasium availability are the most thresholding factors for maximum growth and yield. The tuber yield of sweet potato varies depending on growing area therefore a fertilization program, especially in the type and the dose of the fertilizers, is required. This research was conducted in the Pasir Muncang experimental farm at Gadog, Bogor, West Java, Indonesia. The study site is located ±500 meters above sea levels, 6°39’31.90” south latitude and 106°52’7.77” east longitude. The experiment was started in May to September 2017. Multi nutrient response method was used for this study, and the interpretation of the results was used to develop fertilizer recommendations using single-nutrient quadratic model. The recommendation was determined using N, P2O5, K2O fertilizer response curve, where the first recommendation was calculated from the maximum relative yield,and the second, third, and fourth recommendation were determined from N, P2O5, K2O threshold. Each treatment for N, P and K was evaluated with different level of fertilizer dose using a randomized complete block design with three replications. The fertilizer doses were 50, 100, 150 and 200% from reference (100% N = 100 kg N ha-1, 100% P = 75 kg P2O5 ha-1, dan 100% K = 100 kg K2O ha-1). Relative yield of sweet potato (y), response to fertilizer (x) had improvement quadratically with equation y = -0.0017x2 + 0.538x + 40.035 for N, y = -0.0041x2 + 0.8595x + 38.211 for P2O5, and y = -0.0025x2 + 0.4318x + 73.377 for K2O. The optimized dose of fertilizer to get maximum yield of sweet potato tuber is 158.23 kg ha-1 of N, 78.60 kg ha-1 of P2O5, and 83.60 kg ha-1 K2O, or 343.97 kg ha-1 of Urea, 218.53 kg ha-1 of SP36 139.33 kg ha-1 of KCl.Keywords: multi nutrient response, nitrogen, relative yield, phosphorus, potassium

Published: November 2019

Fruits and young shoot of Solanum nigrum Linn are harvested and consumed as indigenous vegetables by different Indonesian ethnics. Preharvest factors and harvesting methods to maximize the quality of S. nigrum produce is still unknown. In this study S. nigrum was grown in full irradiance and under shading and assessed for their growth, and fruit and shoot yields. The experiment was conducted at the Leuwikopo Experimental Farm in Bogor Agricultural University, Indonesia from April-July 2017. The results demonstrated that plants produced more fruits and shoots in full irradiance, i.e., 687.9 g and 211.1 g per plant, whereas only 331.1 g and 116.9 g per plant were produced in 50% shading. Although fruit and shoot production were superior under full irradiance, shoot-harvested plants had healthier leaves and life span of about 2 months longer thus facilitating longer availability. Canopy of shoot-harvested plants formed a columnar shape with 23 to 45 cm in height, in contrast to spherical shape with 48 to 203 cm in height of the fruit-harvested plants. It is likely that shading level might contribute to farmers’ decision to harvest the shoots or fruits of S. nigrum. Further studies are needed to determine the effects of shading levels on nutritional quality of the shoots and fruits of S. nigrum.

Photoautotrophic System: A Review and Potential Application for Plant Propagation In Vitro
Authors: Krisantini Krisantini , Wiendi Ni Made Armini 
Published: November 2019

AbstractThe standard method of in vitro plant micro propagation uses of tightly closed culture bottles using agar media containing macro and micro nutrients and sucrose as a source of carbon for the explants. The closed bottle culture is usually kept in a temperature and light controlled environment which is lower and of different quality from the natural sunlight, resulting in high relative humidity and no air exchange inside the bottles. Explants produced in vitro have malfunctioned stomata, undeveloped cuticles and lower leaf chlorophyll levels, and hyper hydration of the plantlets. Photoautotrophic tissue culture is micro propagation without or with a reduced sugar level in the culture media, so the growth or accumulation of carbohydrates of the explants is dependent fully upon photosynthesis and inorganic nutrient uptake. This method is usually combined with ventilation or CO2 enrichment, and recently, with incorporating porous materials such as vermiculite, gum or paper pulp to the agar media to promote better root system of the explants. This article discuss the advantages and disadvantages of the photoautotrophic micro propagation compared to the standard micro propagation methods, and provided the results of the photo autotrophic micro propagation studies conducted at Laboratory of Tissue Culture II of the Department of Agronomy and Horticulture, Bogor Agricultural University, Indonesia.

Published: November 2019

Etlingera elatior is tropical ornamental plant commonly called “torch ginger” from Zingiberaceae family. Conventional breeding of E. elatior is limited by cross incompatibility, poor fruit set and low seed production. In this study irradiation of E. elatior with Gamma ray performed to induce mutation. This study was aimed to increase morphological diversity and to obtain unique morphological characters to increase the aesthetic value of E. elatior as ornamental plants and cut flower. Two genotypes of E. elatior, red and white flowers, were tested. The LD20, LD35, and LD50 were determined following intermittent (split dose) Gamma irradiation with a two-hour gap between each gamma ray shot. Red genotype E. elatior explants were irradiated with dose of 3 + 3 Gy (LD20); 4 + 4 Gy (LD35) and 5 + 5 Gy (LD50); white genotype were irradiated with a dose of 2 + 2 Gy (LD20); 2.8 + 2.8 Gy (LD35) and 3.7 + 3.7 Gy (LD50). Non-irradiated explants were set as control. The results of this study indicated that the increase in dose of gamma ray irradiation changed shoot length and number of leaves in the red genotype per explant as compared to control. Morphological changes occurred in leaf shape at 5 + 5 Gy and 3.7 + 3.7 Gy and formation of variegated leaves at 2.8 + 2.8 Gy and 5 + 5 Gy.

Ardisia humilis (Myrsinaceae), known as Lampeni (in Indonesia), is part of the wild flora in Southeast Asia and is known as a weed in some countries. The leaf has medicinal properties for some diseases. The leaves and fruit of this plant are believed to be a treatment for tuberculosis, lung disease, hepatitis, chronic bronchitis, and menstrual irregularities in women. Research into the cultivation of Lampeni is needed to support its usage in Indonesia. The objectives of the research reported here were to find the types and rates of manure to promote leaf production. An experiment was carried out at IPB Experimental Station, Cikarawang Dramaga, Bogor, Indonesia, from December to June 2016. The experiment was laid out in a split plot design with manure types (chicken and cow manure) as main plots and application rates (0, 5, 10, and 15 t ha-1) as sub-plots. The results of the experiment showed that vegetative growth increased with manure application. Total branch number, LAI, leaf fresh and dry weight were higher with 15 t.ha-1 chicken manure or 5 t.ha-1 cow manure application. Leaf analysis showed that pigment concentration responded negatively to increasing manure application and the highest pigment concentration was found on the plants without manure application.
