Abstract

Present research was aimed to study physiological changes of soybean which were inoculated with vesicular arbuscular mycorrhizal fungi (VAM). Glomus etunicatum was exposed to moderate and severe drought condition. Symbiotic association with VAM improved adaptability as it was shown by the increasing leaf proline content. The MLG 3474 and Sindoro are the more tolerant genotypes while the responses of plant to VAM on improving the adaptability to drought were larger on Lokon. Key words: Soybean, mycorrhiza, drought, proline

Abstract

Soil and water conservation treatment have a significant effect on value of C factor and soil erosion.  Vegetatif conservation treatment aimed to reduce of both C factor and soil erosion of the cacao cropping system.  The decrease of both C factor and soil erosion were affected by density of crop canopy and plant rows in counter line, with organic matter addition from system mentioned above.  Experimental method with field study was applied in split plot design consisting three factors, namely (i) slope consisting two levels (10-15% and 40-45%) and (ii) age of the cacao plant consisting two levels (5 to 7 month and 25 to 27 month) were used as main plots (P1 = 5 to 7 month and 10-15%; P2 = 25 to 27 month and 10-15%; P3 = 5 to 7 month and 40-45%;  and P4 = 25 to 27 month and 40-45%), while (iii) vegetatif conservation treatment was used as sub plots consisting three levels, i.e T1 = cacao with disc clearing, T2 = dry field rice and soybean rotation within cacao plants, T3 = T2 + Arachis pintoi as strip plant.  There was not interaction between both cacao plant and slope treatment  with vegetatif conservation treatment to value of C factor and soil erosion.  The value of  C factor in cacao plant and slope treatment P3 (0,43) was significantly different with P4 (0,37). The value of C factor in the vegetatif conservation treatment T1 (0,25) was significantly lower (P < 0,05) than T2 (0,55) and T3 (0,39).  Soil erosion in cacao plant and slope treatment P2 (15,99 ton.ha-1.year-1) was significantly lower than P1, P3, and P4.  Furthermore, soil erosion in the vegetatif conservation treatment T1 (12,95 ton ha-1 year-1) was significantly lower than T2 and T3.  Data analysis with ANOVA (analysis of variance) and Duncan Multiple Range Test (P < 0,05) were done by using SAS program.   Key words: cacao, erosion, the value of C factor

Abstract

Cacao plant is one of the major commodity of plantation in South East Sulawesi, especially in Konawe regency.  Practices of land management implemented by the local cacao farmers in many cases are not in accordance to soil and water conservation principles until caused of soil degradation.  The research was aimed to investigate the alteration of soil physics properties on the local farmers cacao cropping land at different slope as related to canopy cover.  The research was conducted in Amosilu Village, Besulutu District, Konawe Regency, the Province of South East Sulawesi, from December 2006 to September 2007.  The experimental method with field study was applied in split plot design consisting of three factors, namely (i) slope consisting of two levels (10-15% and 40-45%) and (ii) age of the cacao plant consisting of two levels (5 to 7 months and 25 to 27 months) were used as main plots (P1 = 5 to 7 months and 10-15%; P2 = 25 to 27 months and 10-15%; P3 = 5 to 7 months and 40-45%; and P4 = 25 to 27 months and 40-45%), while (iii) vegetatif conservation treatment was used as sub plots consisting of three levels, i.e T1 = cacao with disc clearing, T2 = dry field rice and soybean rotation within cacao plant, T3 = T2 + Arachis pintoi as strip plant.  There was not interaction between both cacao plant and slope treatment with vegetative conservation treatment to soil physics properties, exception on aggregate stability index.  The result showed that vegetative conservation treatment (T1) that is cacao with disc clearing was best alternative because they implied the higher rate of total porosity (61,8%) and the lower rate of bulk density (1,013 g cm-3) as soon as the raising of aggregate stability index as well.   Key words: cacao, canopy cover, conservation, soil physics properties

Abstract

Heritability of fruit characters, such as fruit weight, husk weight, husk thickness, sheal weight, endosperm (water) weight, albumen weight, copra weight, oil content, fruit length and ftuit width. have been estimated on seven coconut populations. The results showed that most of the fruit components of Malayan Red Dwarf (MRD) and Malayan Yellow Dwarf (Mm)had relatively high heritability (>0.80), except fruit weight of MRD (0.74) and albumen weight of MYD (0.78). On the other hand, the heritability of those characters in tall populatidns varied between population. All of fruit characters on Polynesian Tall (PYT) and Seruwai Tall (SAT) had relatively high heritability (>0.80). On West African Tall (WAT), most Of the heritability of the fruit characters were relatively high (>0.80). except husk weight (0.75). endosperm weight (0.79) and oil content (0.41). Heritability of seven characters of Bali Tall (BLT) were relatively high, but those of three characters were relatively low; i.e. husk weight (0.52). fruit width (0.56) and husk thickness (0.71). Three fruit characters of Rmnell Tall (RLT) shown higher heritability. those are husk thickness (0.87), endosperm weight (0.92) and fruit length (0.90).

Abstract

The aim of this research was to test the utilization of arbuscular mycorrhizal fungus (AMF) to improve adaptation ability of chili to aluminum (Al) stress based on growth and yield response in four genotypes of chili (Capsicum annuum L.).  The research was carried out at University Farm of IPB in Cikabayan from September 2006 to Maret 2007.  The media was Ultisol from Gajrug (Lebak, Banten) in polybag.  Four genotypes of chili, PBC 619 and Jatilaba (Al tolerant genotypes), and Cilibangi 3 and Helm (Al sensitive genotypes) were treated with and without inoculation of Gigaspora margarita, and planted further in media without Al stress (Al saturation 0.77%) and Al stress (Al saturation 60.85%).  Variables observed were degree of AMF infection, root length, plant height, shoot dry weight, number of harvested fruits, fruit length, fruit weight and weight of harvested fruits.  The results showed that inoculation of G. margarita effectively decreased negative influence of Al stress by increasing plant height, shoot dry weight, number of harvested fruit, fruit length, weight per fruit and weight of harvested fruits.  Inoculation of G. margarita to Al sensitive genotypes was more advantageous than to tolerant genotypes.  The Al sensitive genotypes were adapted to Al stress if they were inoculated with G. margarita.  In Al stress condition, inoculation of G. margarita to Al sensitive genotypes increased weight of harvested fruits up to 94.49% in Cilibangi 3 and 80.37% in Helm.   Key words: Adaptation, aluminum stress, arbuscular mycorrhizal fungus, Capsicum annuum L., Ultisol

Abstract

This research was aimed at studying the effectiveness of  mycorrhiza, inorganic and organic fertilizer (fish and shrimp waste) on growth, yield and quality of Aloe in peat soil. The study was conducted on peat area, North Pontianak, West Kalimantan. Mycorrhizal application levels (without mycorrhiza, Mycofer and mycorrhizal from pineapple&acute;s rhizosphere) were as main-plot. The inorganic fertilizer (composition of N:P:K:Mg) rates (without inorganic fertilizer;  5 : 4 : 7.5 : 2.5 g/plant;  10 : 8 : 15 : 5 g/plant; and  20 : 16 : 30 : 10 g/plant) were as sub-plot.  Organic fertilizers: (fish; shrimp; fermented fish; and fermented shrimp wastes) were as sub-sub plot. The observed variables were: leaf width, leaf length, leaf fresh weight, plant dry weight, and nutrient uptake (N, P, K, Mg). The results showed that mycorrhizal application improved growth performance and increased N, P, Mg uptake. The best plant growth performance was achieved by N : P: K : Mg  =10 : 8 : 15 : 5 g/plant and fermented shrimp waste treatments.  The highest  N, P, K, Mg nutrients uptake was achieved by application of fermented organic  fertilizer.  Combination of mycorrhiza from pineapple&acute;s  rhizosphere with fermented fish and shrimp waste resulted in higher amino acids content compared to standard cultivation of  Aloe vera Center in Pontianak.   Key words:  Aloe vera, arbuscular mycorrhiza, inorganic fertilizer, organic fertilizer

Abstract

The use of mycorrhiza-plantation crop association has not been widely applied, due to lack of information on the positive effect of the association on the tree crops. The plastic house study was established to evaluate the effect of inoculation of mycorrhiza fungi on the watering efficiency of cacao seeding. Four inoculation treatment of mycorrhiza fungi: without inoculant (control), endomycorrhiza (Gigaspora margarita), ectomycorrhiza (Scleroderma columnare) and double inoculant of both species, were combined on factorial arrangement with four rates of watering interval: once of every 1, 3, 5, and 7 days. Inoculation significantly improved seedling growth as shown by plant height, leaf area and dry shoot weight compared to control treatment. Double inoculation had the best result, followed by endomycorrhiza and ectomycorrhiza, consequtively. Inoculation also significantly increased watering efficiency on cacao nursery as many as 2 to 4 times compared to control and shortened the time of nursery period as long as one month.
