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.

Abstract

Fertilizer administration is a way to increase the productivity of edamame plants.  Synthetic fertilizer is commonly used in edamame cultivation today.  However, excessive use of synthetic fertilizer could reduce soil fertility so that substitution of it with biofertilizer is needed.  This study was aimed at assessing the effects of biofertilizer and synthetic fertilizer administration on the growth and production of edamame plants.  A completely randomized design in a factorial pattern was used.  The first factor was biofertilizer rates consisting of three levels namely no fertilizer (0% R), 5 ml/l (50% R), and 10 ml/l (100% R).  synthetic fertilizer was given in five levels consisting of no fertilizer (0% R), 25% recommended rate (urea 37.5 kg/ha, SP-36 37.5 kg/ha, and KCl 25 kg/ha), 50% recommended rate (urea 75 kg/ha, SP-36 75 kg/ha, and KCl 50 kg/ha), 75% recommended rate (urea 112.5 kg/ha, SP-36 112.5 kg/ha, and KCl 75 kg/ha), and 100% recommended rate (urea 150 kg/ha, SP-36 150 kg/ha, and KCl 100 kg/ha).Results showed that plants given biofertilizer by 100% recommended rate had significantly higher height, number of leaves, and fresh and dry root weight in 5 weeks after planting (WAP).  Synthetic fertilizer administration by 100% recommended rate gave significantly higher plant height, number of branches, number of leaves, and fresh and dry root weight in 5 weeks after planting (WAP).  Interaction of 100% recommended rate of biofertilizer and 100% recommended rate of synthetic fertilizer resulted in significantly higher number of leaves and number of flowers. Keywords: edamame plant.

Abstract

Selection is choosing the good or discarding the bad. The selection index is one of the selection procedures in the plant breeding program when it involves many characters. In this study we used experimental data resulted by split plot design involving 30 maize genotypes planted in 3 environments with 3 replications, so that in each response variable there were 270 observation units. From the 30 genotypes, selection performed using an index of 4 characters with unweighted index methods (equal weight) and weighted index method (different weight), to obtain 5 genotypes with the largest index. The parameters studied include the population average, selection average, selection differential, genetic gain/cycle, and percent genetic gain/ cycle of each response variable. The results of the study showed that both methods always give positive progress on the character chosen as selection criteria, but not necessarily give positive progress to other characters. In practice the selection in the field we should consider the heritability. Keywords: index selection, selection differential, genetic gain / cycle, heritability
