Abstract

The productivity of cucumber in ultisol soil is commonly low due to problems of soil fertility and physical soil properties. Organic fertilizers like vermicompost can be used as a solution to improve soil fertility. The study was conducted from August to December 2015 in the Integrated Field Laboratory, Faculty of Agriculture, University of Lampung. The study used a randomized block design (RAK) factorial 2 x 4. The first factor was the dose of vermicompost 0%, 10%, 20%, 30%, and the second factor, soil depth 0-20 cm (S1) and 20-40 cm (S2). Variance of homogeneity test was performed using Bartlett test and test of additivity by Tukey's test. Variance data and differences in the median value of treatment tested with Honestly Significant Difference (HSD) at 5% level of confident. Correlation test was performed between plant growth by pH, organic C, total-N, P-available, uptake of N and P plant at 5% level of confident. The results showed that (1) Application of vermicompost at a dose of 30% is best for fruit weight, fruit diameter, the weight of dry stover and pH of the soil, uptake of N and P uptake cucumber plants. (2) The number of female flowers cucumber plants and soil pH is higher at a depth of 0-20 cm compared with a depth of 20-40 cm Ultisol Natar. (3) There is no interaction between soil depth and vermicompost on growth, the production of cucumber plants, soil pH, uptake of N and P uptake by cucumber plants.

Abstract

Tuberose (Polyanthus tuberosa L.) is a popular ornamental plant in Indonesia as cut flowers and sowing flowers. It can be used as potted flowers by making the flower stalks shorter. One way to get tuberose that have criteria as potted flowers is by administering growth inhibitors using Paclobutrazol. This research was conducted at the Greenhouse of the Horticultural Building, Faculty of Agriculture, University of Lampung in November to August 2017, aimed to determine the effect of the concentration of paclobutrazol on the growth and appearance of tuberose and to determine the best concentration of paclobutrazol in the appearance of potted tuberose. This study used a randomized block design (RCBD) with a single treatment with 6 levels of paclobutrazol concentration, namely 0, 75, 150, 225, 300, and 375 ppm with 3 replications. Homogeneity of variance was tested by Bartlett test and additivity was tested by Tukey test. Then, it was continued with the F test and with the Least Significant Difference test (LSD) at the 5% level. The results showed that administration of paclobutrazol was significantly affected pseudo stem circumference and all variables of generative growth except the length of the florets. The concentration of paclobutrazol up to 375 ppm has not obtained optimum results. Keywords: Concentration, growth, paclobutrazol, tuberose

Abstract

Shallot is one of important horticultural crops in Indonesia; shallot consumption per capita is estimated to be 4.6 kg per year. The objective of this study was to evaluate the effect of combining biofertilizer and organic fertilizer on the production of shallot in Sukabanjar village, Pesawaran, Lampung, Indonesia. The study was set up using a randomized completely block design with two factors, biofertilizers and various organic fertilizers, i.e. cow manure, chicken manure, rice straw compost, oyster mushroom baglog. Our study demonstrated that combining biofertilizer and organic fertilizer significantly increased the number, diameter, and fresh and dry weight of tubers of “Bima Brebes” shallot. Shallots treated with biofertilizer combined with oyster mushroom baglog produced the highest tuber yield of 1788 g compared to 282 g in the control.

Abstract

Spatifilum (Spathiphyllum wallisii) is a popular ornamental plant that can be used as indoor decoration, so its appearance should be attractive.  Apart from flowering, an interesting criteria for the appearance of the spatula is to have many tillers so that it looks lush.  One of the efforts to obtain this appearance is the provision of a growth regulator capable of accelerating shoot growth, namely Benzyladenine (BA).  The purpose of this study was to determine the concentration of BA which produced the best effect on spatifylum growth.  This research was conducted in the greenhouse of the Horticulture Building, Faculty of Agriculture, University of Lampung from July 2019 to January 2020.  This research was arranged in a structured single factor treatment design consisting of six BA concentration treatments, namely 0 ppm, 10 ppm, 20 ppm, 30 ppm, 40 ppm, and 50 ppm with six repetitions.  Data analysis used standard deviation which is presented in the form of a histogram by taking the average value of each treatment.  The results showed that the administration of benzyladenine with concentrations 10-50 ppm tended to increase spatifylum growth in the variable leaf area, leaf greenness, tiller emergence, number of tillers, flower emergence time, and number of flowers, but had no effect on the addition of plant height and number of leaves.  Giving benzyladenine with a concentration of 20 ppm was quite efficient in optimizing the vegetatif growth of spatilum, which was shown by the increase in plant height, increased number of leaves, time to emergence of tillers, and number of tillers.  On the other hand, the effect of benziladenine on the generative phase requires a higher concentration, namely at a concentration of 50 ppm, the time for which the flower buds appear is the fastest and the number of flowers is the most.  Keywords:  Benzyladenine, Concentration, and Spatifillum.

Abstract

Shallots (Allium ascalonicum L.) is one of the leading vegetable commodities used as food seasoning and traditional medicine. This study aims to see the effect of providing various doses of NPK fertilizer and types of biological fertilizers on the growth and production of shallot plants. This study used a randomized block design (RAK) arranged in a factorial (4 x 2). The first factor is the NPK fertilizer dosage which consists of four levels, namely: N0= 0% (without NPK fertilizer), N1= 50% (25 g/m2), N2= 100% (50 g/m2), and N3= 150% (75 g/m2). The second factor is the type of biological fertilizer which consists of two levels, namely: H1= Grikulan plus fertilizer and H2= EM4. The results showed that the NPK fertilizer dosage treatment up to a dose of 75g/m2 gave the best results on plant growth and development, including the number of leaves, plant height, fresh tuber weight per plant, wind dry tuber weight per plant, and wind dry tuber weight per m2. The growth and development of shallot plants with the application of Grikulan biological fertilizers were better than those of EM4 biological fertilizers. Treatment of NPK fertilizer dosage of 150% or equivalent to 75 g / m2 supplemented with the application of Grikulan plus fertilizer results in higher production, namely the weight of dry tubers per m2 reaching 1674.33 g or equivalent to 11.72 tonnes/ha. Keywords : EM4, Grikulan plus, shallots,NPK, yield

Abstract

Peningkatan produksi bawang merah banyak menghadapi kendala salah satunya yaitu serangan hama dan patogen. Penyakit yang sering dijumpai pada budidaya bawang merah yaitu moleryang disebabkan oleh Fusarium oxysporum f. sp. cepae. Penyakit moler dapat menimbulkan kerusakan danmenurunkan hasil umbi hingga 50%. Penggunaan pupuk kandang sapi, arang sekam dan pestisida teki diharapkan dapat menekan intensitas penyakit moler pada tanaman bawang merah. Penelitian ini bertujuan untuk mengetahui pengaruh kombinasi pupuk kandang sapi, arang sekam dan pestisida teki terhadap intensitas penyakit moler pada tanaman bawang merah dan mengetahui pengaruh kombinasi pupuk kandang sapi, arang sekam dan pestisida teki terhadap pertumbuhan dan produksi tanaman bawang merah. Penelitian dilakukan di Laboratorium Penyakit Tanaman dan Laboratorium Lapang Terpadu, Fakultas Pertanian, Universitas Lampung, pada September hingga Desember 2019.  Perlakuan dalam penelitian ini disusun dalam  Rancangan Acak Kelompok (RAK) yang terdiri dari 8 perlakuan. Perlakuan diulang sebanyak 3 kali sehingga total unit percobaan yang digunakan sebanyak 24. Perlakuan terdiri dari kombinasi taraf dosis pupuk kandang sapi 5, 10 dan 15 ton/ha dengan arang sekam 5, 10 dan 15 ton/ha kemudian ditambahkan pestisida teki dengan dosis 5%. Hasil percobaan dari kombinasi pupuk kandang sapi dan arang sekam pada berbagai taraf dosis tidak menunjukkan pengaruh terhadap pertumbuhan bawang merah tetapi memberikan pengaruh nyata terhadap produksi bawang merah. Pestisida teki dengan konsentrasi 5% tidak memberikan pengaruh nyata terhadap pertumbuhan dan produksi bawang merah tetapi pestisida teki dengan konsentrasi 5% memberikan pengaruh nyata terhadap penurunan intensitas penyakit pada bawang merah. Kombinasi dosis pupuk kandang sapi 15 ton/ha, arang sekam 15 ton/ha dan pestisida teki 5% menunjukkan intensitas terserang penyakit paling rendah.

Abstract

Fruit quality is an important aspect that requires attention and more study when it comes to commercializing tropical fruits, including guava ‘Kristal’. This study aimed to evaluate the effect of bagging treatment and altitude of growing orchard on fruit quality of guava (Psidium guajava var. ‘Kristal’). This study was conducted at two local orchards managed by small-scale farmers, at Gunung Batu (1000 meters above sea level, m asl) and Brajaselebah (25 m asl), Lampung Province, Indonesia. A nested design was applied to test 5 types of bagging treatments and 2 levels of land altitude. Fruit quality was assessed by measuring both physical and chemical characteristics. Fruit size indicated by fruit weight and diameter was significantly larger in lowland compared to highland. The total soluble solids (TSS) were significantly higher in the lowland compared to the highland, while titratable acid (TA) showed an opposite result. Vitamin C of the fruits varied from140 to 146 mg per 100 g. Different types of fruit bagging and land altitudes did not affect the physical and chemical characteristics of “Kristal” guava fruits. Fruit scar intensity was higher in lowland, especially in fruit without bagging. Fruit bagging is highly recommended for farmers due to the success of this treatment to reduce fruit scar intensity, thus resulting in good fruit quality, irrespective of the growing locations.
