Abstract

The problem of propagation of Punica granatum, was hard seed, and it difficult to germinate. One of the efforts to solve the problem is using H2SO4 as to breakdown of the hard seed. This study aimed to obtain the best concentration of H2SO4 and soaking time, as well as the interaction between H2SO4 concentration and soaking time on the germination of  Punica granatum seeds. This study used a completely randomized design (CRD) consisting of 2 factors. The first factor is H2SO4 concentration (0%, 20%, 40%, 60%, and 80%), and the second factor is soaking time (10, 15, and 20 minutes). Parameters observed were germination, germination rate, vigor index, germination height, root length, weight of sprouts, and dry weight of Punica granatum sprouts. The results showed the use of water was the best treatment on germination (85.30%), germination rate (17.37 days), vigor index (2.24%), germination height (7.80 cm), and root length of Punica granatum (7.05 cm), soaking time did not effect the germination of Punica granatum, and the interaction between the use of water and the soaking time 15 minutes was the best treatment on the parameters of fresh weight of sprouts (0.17 g) and dry weight of Punica granatum sprouts (0.13 g).

Abstract

Soybean is one of the main needs and sources of vegetable protein for Indonesian. National needs of  soybean continue to increase in line with the increase of population, but soybean production has not been able to meet national needs. Therefore, efforts need to be made to increase soybean production by utilizing marginal land with using arbuscular mycorrhizal fungi and biochar. The aim of this study was to determine the effect of single factors of arbuscular mycorrhizal fungi (AMF), biochar and interaction of these two factors on the growth and yield of soybean in Ultisol soil. This research was conducted from  December until March 2019. The research used 3 x 3 factorial completely randomized design with three replications. The first factor was AMF dosage consist of 3 levels : M0 (0 g per plant), M1 (15 g per plant), M2 (30 g per plant) and the second factor was type of biochar consist of 3 levels : B0 (without biochar), B1 (biochar of rice husk), B2 (biochar of coconut shell). The observation data that obtained were analyzed statistically using analysis of variance (ANOVA). The results of variance analysis were continued by Duncan's multiple range test at level 5%. The results showed that the treatment of AMF improved all growth and yield parameters and the single biochar can not improve all growth and yield parameters. The interaction between AMF and biochar did not improve all parameters of growth and yield of  soybean.

Abstract

Potato (Solanum tuberosum L.) has been classified as major source of carbohydrate along with rice, wheat, and corn. As for other crops, potato’s growth and yield are always subject to weed interference. An experiment has been conducted to study the effect of indigenous rhizobacteria to promote the growth and yield of potato var. Cingkariang and weed population at Nagari Pakan Sinayan, Agam District, the Province of West Sumatra. The experiment used a completely randomized design with seven treatments and three replications. The treatments was rhizobacteria indigenous to potato farm at Nagari Pakan Sinayan i.e SWL2.2, Ag2L2S3.3, Ag2L2S4.2, Ag3L3S3.1, Ag3L3S5.1, Ag4S5.2, and one group of without the isolate. Data were analysed with analysis of variance and mean separation following DNMRT at 5%. Results demonstrated that indigenous rhizobacteria promoted plant height, number of branches, and the weight of potato tubers. The rhizobacteria also resulted in changes in weed population. Ten weed species were found prior to the experiment as follows: Ageratum conyzoides L.,  Alternanthera philoxeroides (Mart.) Griseb., Andrographis paniculata (Burm.f) Nees, Bidens pilosa L., Cyperus rotundus L., Crassocephalum crepidioides (Benth.) S. Moore, Eleusine indica L., Echinochola colona (L.) Link, Galinsoga quadriradiata Ruiz & Pav., dan Paspalum commersonii Lamk. However, three new weed species emerged during the experiment. They are Amaranthus spinosus L., Portulaca oleracea L., and Paspalum conjugatum P.J.Bergius indicating changes in weed population.

Abstract

The chili yellow leaf curl disease is one of the biggest obctacle in chili’s production in Indonesia. This diseases only transmitted by whitefly (Bemisia tabaci). One of the disease controlling method is by using Plant Growth Promoting Rhizobacteria (PGPR) to reduce pesticide application for the health and environment. The aim of this research is to find out the effectiveness of Streptomyces sp. and Bacillus sp. in supressing yellow leaf curl disease, plant growth and chili harvest. This research has conducted at the experimental farmer’s field in Harjobinangun, Pakem, Sleman, Special Region of Yogyakarta. Using varieties of chili Twist 42, Streptomyces isolates which from Bacteriology Laboratory collection’s with 10-8 CFU/ml and Bacillus isolates which is from Mycrobiology Laboratory collection with  10-8 CFU/ml. The result of this research showed that the treatment of combination between Bacillus sp. and Streptomyces sp. could decrease and supress disease incidence and disease intensity if it compared with others treatment. Parameters of plant growth included plant high, stem diameter, root length, root volume and number of productive branch showed that single of Streptomyces sp. and Bacillus sp. without combination were better than combination and untreated.  The single application Streptomyces sp. or Bacillus sp. could increase amount of total number and weight of fruits.

Abstract

Aphelenchoides besseyi is one of the most important parasitic nematodes in rice plants, capable of dormancy in rice seeds. This study aims to determine the effects of soaking rice seeds in water and pesticides (carbosulfan, benomyl, and imidacloprid) on the mortality of A. besseyi, seed viability, and symptoms in rice seedlings. This study specifically used rice seeds infected with A. besseyi. Cold water treatment (cwt) at 5-10ËšC for 24 hours followed by hot water treatment (hwt) at 52ËšC for 10 minutes caused 51.17% A. besseyi mortality yet reduced the seed viability. Soaking the seed in the water at 25-30ËšC for 24 hours followed by hwt at 57ËšC for 10 minutes and hwt at 52ËšC for 10 minutes could cause 48.67%, 39.18% and 33.05% nematode mortality, respectively. Low nematode mortality in all treatments (less than 60%) showed symptoms of A. besseyi infection in rice seedlings 21 days after planting. Seed dressing with imidacloprid 5WP (2% by seed weight) caused 47.25% A. besseyi mortality, whereas benomyl 50WP (0.2% by seed weight) and carbosulfan 25ST (2% by seed weight) caused only 27.61% and 11.34%. Based on two parameters (nematode mortality and seed viability), the most effective treatments were soaking the rice seeds in the water at 25-30ËšC for 24 hours and seed dressing with imidacloprid.

Abstract

Seed propagation of strawberry by in vitro culture is needed to obtain high quality seeds of strawberry in large quantities. In in vitro culture, a large number of shoots is expected can be produced at the multiplication stage. Cytokinins type of PGR can be added to culture media to produce a large number of shoot. The focus of this research was to compare the effect of BAP and Kinetin affected Sweet Charlie strawberry multiplication. The experiment was located at the Seed Technology Tissue Culture Laboratory, Faculty of Agriculture, Padjadjaran University. The experimental design was a Completely Randomized Design (CRD) with two treatments of different types of cytokinin, namely Benzyl Amino Purine (BAP) and Kinetin at 1 mg L-1 on Murashige and Skoog (MS) basic media, each treatment was repeated four times. This study showed that BAP had a better effect than Kinetin on the number of shoots, number of leaves, and wet weight of strawberry Sweet Charlie cultivar. The addition of BAP was recommended over Kinetin to obtain the highest number of shoots, the highest number of leaves, and the highest wet weight of culture on strawberry Sweet Charlie cultivar.
