Abstract

This study was aimed at assessing the effects of shade on the growth, productivity of indigenous vegetables pohpohan and reundeu.   A split-plot design was used.  The main plot was shade treatments consisting of four levels, namely 0% (no shade), 25%,  50%, and 75%.  The subordinate plot was the seed origins, namely Sukabumi, Cianjur, and Bogor.  The arrangement of the main and sub plots was done based on a completely randomized design.  Results showed that  in pohpohan increased plant height was found in 50% shade treatment, while leaf length and width was found to be increased in shade treatment up to 75%.  Leaf length and width of pohpohan plants of Bogor origin were higher than those of pohpohan plants of Cianjur and Sukabumi origins. In reundeu plants, no effects of shade treatments were found in all variables measured.  Reundeu plants of Bogor and Cianjur origin were found to be superior in plant height, leaves number, length, and width, and fresh and dry  weight. Pohpohan plants were potential to be grown under shades.    Key words: seed origin, plant height, pohpohan, reundeu, Bogor

Abstract

Pummelo plants in Magetan Regency were found to spread over several villages and their accessions have their own morphological and chemical characteristics.  This study was aimed at assessing the distribution and the number of pummelo accessions in Magetan Regency.  The study was conducted in Magetan Regency East Java from May to July 2015.  Observation was conducted on distribution marking and accession characteristics by using a survey method.  Results showed that the accessions of pummelo plants grown by farmers in Tambak Mas Village were varied but they were not evenly distributed.  Meanwhile, pummelo plants grown by farmers in Dukuh Village had uniform accessions with uneven distribution.  Results of  field observation obtained 13 pummelo accesions, namely Adas Duku, Adas Nambangan, Bali Putih, Bali Merah 1, Bali Merah 2, Gulung 1, Gulung 2, Gulung 3, Magetan, Jawa 1, Jawa 2, Jawa 3, dan Sri Nyonya.  The most commonly pummelo accessions found in Tambak Mas Village were Adas Nambangan and Adas Duku.  Meanwhile the most accessions planted in Bendo Village were Adas Duku and Sri Nyonya. Key words: pummelo, Adas Nambangan, Tambak Mas, Dukuh, survey method

Abstract

This study was aimed at assessing the efficacy of several multiple liquid biofertilizers found in the market on the growth and production of sweet corn. A factorial completely randomized design was used. The first factor was the type of multiple liquid biofertilizers (PHMC) consisting of three levels, namely PHMC 1, PHMC 2, and PHMC 3. The second factor was synthetic fertilizer rates consisting of five levels, namely 0, 25, 50, 75, and 100% of recommended rate (R). Results showed that the application of PHMC 3 combined with synthetic fertilizer treatments (05 R and 25% R) significantly increased  stem diameter (8 WAP). Plants treated with PHMC 3 application were found to have significantly higher number of leaves than those treated with PHMC 2 application at 6 WAP. Plant height, number of leaves, and weight, length, and circumference of main cob of plants treated with 50%R synthetic fertilizer were higher than those of plants treated with 0%R and 25%R synthetic fertilizer. Meanwhile, plants treated with 75%R synthetic fertilizer were found to have better values for girth, leave width, flowering time, harvesting time, number of cobs, dry weight of shoots and roots, grain total soluble solids (TSS) content, and cobs weight  than those of plants treated with 0, 25, and 50%R synthetic fertilizer. Key words: sweet corn, multiple liquid biofertilizers, TSS, synthetic fertilizer.

Abstract

This study was aimed to determine the effect of dosage of  cow manure and, dolomite on the growth and production of long  beans. This research was conducted in experimental field of Agroteknologi Department of Djuanda University Bogor. The study was prepared according to Completely Randomized Design (RAL), factorial. The first factor was the dose of cow manure according to recommendation consisting of 4 levels: 0R, 0.5 R, 1R, and 1.5R . The second factor is the recommended dolomite consisting of 4 levels: 0R, 0.5 R, 1R, and 1.5 R.  The results showed that the average height of the plant at age 6 MST, the number of leaves 4 MST and 6 MST, the number of flowers and the amount of fruit 6 MST, wet fruit weight of 3rd fruit harvest, dry weight of stem aged 8 MST influenced by cow manure.  While plant 4 MST, number of leaves 4,6 and 8 MST, number of branches 4, 6 and 8 MST, 6.8 MST of flowers and number of fruit 6,8 MST, weight lenghtof fruit harvest to-1, wet fruit weight of whole harvest 1st, dry weight of 3rd harvest, wet weight of stem, dry weight of stem, wet weight of root influenced by dolomite.Keywords: Long beans, plant height, the amount of fruit, fruit weight

Abstract

The aim of this research is to know the repellent ability of lerak fruit extract (Sapindus rarak DC.) and kirinyuh leaf extract (Chromolaena odorata) against Callosobruchus maculatus warehouse pests. The research activity was conducted in October - December 2016 at Entomology Laboratory, SEAMEO BIOTROP Bogor. This research used two experiments that were using lerak fruit extract and kirinyuh leaf extract. The experimental design used was Completely Randomized Design with three replications for each concentration level of extract material. The extract concentrations used for the preliminary test were 1.0%; 2.0%; 3.0%; 4.0% and 5.0%. In the main test the concentration refers to the results of the preliminary test. The concentration of lerak fruit  extract used for the main test were 1.5%; 3.0%; 4.5%; 6.0% and 7.5% (v / v), the concentration of kirinyuh leaf extract were 0.0%; 2.5%; 5.0%; 7.5% and 10.0% (v / v). The effectiveness of repellent ability be classified well if repellent ≥80%, good enough if 60% ≤ repellent <80% and less good if repellent <60%. The highest repellent content of lerak fruit extract on 72  hours after treatment (JSP) was 77.9% occurring at 4.5% extract concentration and highest repellent of kirinyuh leaf extract on 72 JSP was 82.73% occurring at 10.0% extract concentration. Repellent ability of kirinyuh leaf extract is better than repellent ability of lerak fruit extract. Keywords: repellent power, vegetable extract, extract concentration, pest controlling

Abstract

This study was aimed at assessing the growth and production of celery plants grown with various compositions of N,P and K fertilizer and compost. The study was done at the Trial Farm of Faculty of Agriculture, Djuanda University, Bogor fiom September to November 2015. A completely randomized design with two factors was used. The factors consisted of compost rate and N,P and K fertilizer rate. Compost was given in four levels, namely no compost (0% R), 26.3% gcompost/plant (50% R), 52.5 g compost/plant (100% R), and 78.7 g compost/plant (150% R). N, P and K fertilizer was given in five levels, namely no fertilizer (0% R), 4 g Urea, 0.3 g SP-36, 0.2 g KCl (25% R), 0.9 g Urea, 0.6 g SP-36, 0.4 g KCI (50% R), 1.3 g Urea, 0.8 g SP-36, 0.6 g KCl (75% R), and 1.7 g Urea, 1.1 g SP-36, 0.8 g KCl (100% R). All fertilizers were administered gradually at the time of planting and 2 weeks after planting. Three replicates were allocated into each treatment making up 60 experimental units. Results showed that celery plants given synthetic fertilizer at 100% R had higher plant height, number of leaves, number of seedlings, harvest fresh weight (g), saleable fresh weight (g), root biomass (g), and root dry weight (g) than those treated with no fertilizer (0% R). Plants treated with 150% compost had higher plant height, number of leaves, harvest fresh weight (g), saleable fresh weight (g), root length (cm), and root dry weight (g) than those treated with no fertilizer (0% R). Thus the best celery growth and production in this study was obtained on plant 150% R compost   and 100% R synthetic fertilizer nourished.Key words: celery, compost, N, P, K fertilizer, harvest flesh weight
