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

Pitcher Plant {Nepenthes mirabilis (Lour.) Druce} Growth in Different Compositions of Planting Medium and Level of ShadingABSTRACTThis research aimed to determine the effects of various compositions of planting medium and level of shading on the vegetative growth of the pitcher plant (Nepenthes mirabilis (Lour.) Druce). The experiments were arranged in a split plot arrangement on randomized blok design. The main plot was paranet shading (0%, 25%, 50%, 75%), and the sub-plots were planting medium compositions (cocopeat : rice husk charcoal (1:0) (1:0), cocopeat : rice husk charcoal (0:1) (0:1), cocopeat : rice husk charcoal (1:1) (1:1), cocopeat : rice husk charcoal (1:2) (1:2), cocopeat : rice husk charcoal (2:1) (2:1)). Increased shading levels from 0% to 75% caused N. mirabilis plants to be shorter and rosetted, with larger leaf surface area and more leaves and pitchers, but with smaller-sized pitcher. Nepenthes mirabilis which were planted in 1:1 medium showed have more leaves, and pitchers, larger pitchers, greater leaf surface area and longer roots, compared with those planted in 1:2 medium. However, the number of leaves and root length of plants in 1:1 medium was not significantly different to those in 1:0 and 2:1 medium. Pitcher size of N. mirabilis  planted in 1:1 medium was not significantly different to those planted in 1:0 and 0:1 medium. The number of pitchers and leaf area of N. mirabilis planted in 1:1 medium was not significantly different to those planted in 0:1 and 2:1 medium. The pH level of 1:0 medium was lower than 0:1 medium at different levels of shading.Key words : Nepenthes mirabilis (Lour.)

Abstract

The study was aimed at assessing the response of soybean plant (Glycine max L.) to inoculation of arbuscular mycorrhizae and application of phosphorus fertilizer on acidic soil. The study was conducted from February to June 2013. A factorial completely randomized design was used. The first factor was inoculation  of mycorrizhae consisting of two levels, namely no inoculation and mycorrizhae inoculation of 10 g/plant. The second factor was the application of phosphorus fertilizer in four levels, namely 0 kg SP-36/ha, 100 kg SP-36/ha, 200 kg SP-36/ha, and 300 kg SP-36/ha. Results showed that soybean plant given no mycorrhizae of 10 g/plant had higher plant height at 3 weeks after planting (WAP) than those given no mycorrhizae. The application of phosphorus fertilizer was found to give significant effects on plant height at 4-7 WAP, number of leaves at 6 WAP, trunk diameter, root  length, number of productive branches, fresh and dry weight of roots, fresh and dry weight of root nodes, age at first flowering, number of root nodes, leaf width, pod dry weight, number of one seeded pods and three seeded pods. It was also found that the interaction between inoculation of arbuscular mycorrhizae and application of phosphorus fertilizer gave significant effects on number of leaves at 7 WAP, canopy dry and fresh weight, pod fresh weight, number of two seeded pods, total plant fresh and dry weight, total dry seed weight, number of total pods, and number of seeded pods.Key words: Glycine max L., root nodes, pod dry weight, seeded pods

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.
