Abstract

A field experiment of drip irrigation was set up in the field on dry land farming at Patas Gerokgak, Buleleng.The aim of the experiment was to demonstrate to the local farmer about the beneficial goal of drip technology inorder to gain a high efficiency of water application. Three intervals of water application, i.e. : 2 days, 4 daysand 6 days (I1, I2, I3) in drip technique, and application of Mineral Plus fertilizers (M1) and without Mineral Plusfertilizers (M0) was observed in a nested block design. Bali grape varieties were used as an indicator. Parameterswhich were observed in second year experiment included the water distribution as indicated by soil water contentat 0 – 15 cm depth, and soil water matrix potential (0 – 30 cm depth) which indicated by Loctonic tensiometer.Plant growth was observed by measuring fresh and dry weight biomass and diameter of grape stalk, regularly. Theresult of the experiment showed that, soil water content of 0 – 15 cm depth was not significantly affected by thetreatment. Plant growth as indicated by fresh weight of biomass, dry weight of biomass and diameter of grape stalkwere not significantly affected by the treatment There were no significant differences between treatments on freshand dry weight biomass, dry biomass and diameter of grape stalk so that the yield of grape as indicated by numberbunch of grape per plant, fresh weight of grape per bunch, fresh weight of grape per plant, dry weight of grapeper bunch, number of grape per bunch were not significantly affected by the treatment. Yield quality as indicatedby volume of grape per pellet, sugar content of grape and colour of grape were no significant differences betweentreatments.

Abstract

Garlic (Allium sativum L.) Local Sanur variety is one of garlic varieties which are commonly cultivated inBali. This variety has not been identified, although it has been known having good agronomical, as well as goodmorphological characteristics. The aims of this study were to identify Local Sanur variety has good characteristicsfor cultivated at low land area. This experiment was conducted at Sanur, the eastern region of Denpasar. The seedswere planted on the 5.0 m x 2.5 m garden bed with the plant spacing of 25 cm x 25 cm. There were 15 replications,hence, 15 garden-beds all. Each garden-bed was divided into two parts. The plants on a part side were used asdestructive samples, which were required for the variables of growth analysis, and for determination of the periodof vegetative and bulbing phase. Whereas the plants on the other part were used for the variables of plant growthand yield. The result show that the variety of Local Sanur had specific characteristics as described below: the plantheight ranged 48.9 to 56.7 cm, the leaf number was 5.14 to 6.06; the leaf size were 35.73 to 40.73 cm in length and1.05 to 1.39 cm in width. The bulbing phase was commenced at 49 days after planting; therefore the vegetativeperiod was 49 days. The bulb was harvested at 85 days after planting, indicated the bulbing period of 36 days.The yield was 4.82 to 6.60 tons of dry weight per hectare. It was also identified that the bulb has oval shape (egglike)with white flesh and yellowish white skin. Those characters indicated that Local Sanur Varierty suitable fordeveloping at low land area.

Abstract

The objective of this research was to study the change of vegetative growth of root on some genotypes soybeanof aluminium toxicity, drought stress, and double stress (Al toxicity and drought stress). Research in rooting systemof soybean is hoped to get more attention, especially for supporting concept of new plant type for high yieldingpotential. Six genotypes of soybean (Slamet, Sindoro, Dieng, Sinyonya, Lumut, and Wilis), treated with aluminiumsaturated (Al 25%, Al 50%, and Al 75%) and field capacity (80% FC and 40% FC). Response of growth vegetativeidentified perception by root dry weight. Result of the study show that only one from six that is genotype Wiliswas tolerant at aluminium toxicity, drought stress, and double stress.

Abstract

The parasitoid T. evanescens was reared in the laboratory, then; one, two, three, four, five, six female parasitoidrespectively was released to one hundred eggs of ACB in the tube. The second experiment, the parasitoid wasreared in the laboratory until ten, fifteen, twenty and twenty five generations, than released to one hundred eggs ofACB. The observation was done five days after releasing parasitoid. The result of the experiment showed that themaximum parasitism on the eggs of ACB 53.2% at four female parasitoid per hundred eggs of ACB. The increaseof the number female parasitoid, the parasitism degree per one female parasitoid, and the emergence of the newparasitoid from egg were decreased. The parasitoid T. evanescens that reared in the laboratory by using substitutedhost Corcyra cephalonica was still effective up to tenth generations to control the eggs of ACB. Parasitoid thatrearing after tenth generations, the parasitism degree, the new emergence parasitoid from the egg of ACB andwalking or jumping speed of parasitoid was decrease.

Abstract

In a survey of chrysanthemum growing fields and greenhouses in Brastagi, Sumatera Utara; Cianjur, JawaBarat; Malang, Jawa Timur; and Tabanan and Buleleng, Bali, some chrysanthemum cultivars were found showingmild leaf mottling, vein-clearing or vein banding of leaves and slight loss of flower quality. Out of 287 samplessurveyed, the disease incidence ranged between 7.50% and 67.44%. Through DAS-ELISA, the saps extractedfrom diseased plant samples, 34.84% were found to be positively reacted with serum anti-CVB, but not with seraanti- CMV, -TSWV, -PVY and -TMV. The virus isolate was then designed as CVB Indonesian isolate. The viruswas sap-transmissible to narrow host range. The virus induced systemic symptom on Nicotiana benthamiana, N.clevelandii, N. tabacum var. Burley, N. tabacum var. Havana; local necrotic lesion on Chenopodium amaranticolo,C. quinoa and both local and systemic symptom on Petunia hybrida.

Abstract

The objective of this experiment was to study the effect of mulching and organic fertilizer on growth and yieldof shallot (Allium ascalonicum L.) in coastal seaboard. The experiment was arranged in Randomized CompletelyBlock Design (RCBD) with two treatments. First factor are mulching with two levels: without mulch (M0) and withmulch (M1). Second factor are dosages of organic fertilizer: without fertilizer (P0), 10 T Ha-1 fertilizer (P1), 20 THa-1 fertilizer (P2), 30 T Ha-1 fertilizer (P3), 40 T Ha-1 fertilizer (P4), and 50 T Ha-1 fertilizer (P5). The experimenttreatment was arranged by three replications. The data were analysis by variance and LSD analysis, correlationanalysis, and regression analysis. The results showed that the interaction effects of the mulching and organic fertilizeron growth and yield of shallot were significantly different , except on the 10 T Ha-1 (P1) to 30 T Ha-1 fertilizer(P3) the treatment was no effect on total leafs per hill in without mulch (M0). The highest yield of bulb was 7.78Q Ha-1 without mulch (M0) and 12.27 Q Ha-1 with mulch (M1). The effect of mulching was increase the yield was35.13 %.

Abstract

Total rice field area in West Sumatera is 221.165 ha. The largest portion of irrigated rice is on 0 – 1200 m asl.The major preference of Indonesia rice consumers, the West Sumatera consumers prefer high amylose content rice.The availability of rice variety with high amylose is very limited; consequently, the dominant varieties planted bythe farmers were Cisokan and IR 42 that has been cultivated for more than 1 0 years. By single variant analyze forgenotype yield data were absolutely different. According to average yield of 21 grows environment, SPR85163-5-1-2-4 line and S4362f-Kn-2-1-2 showed the sheet for each line 10 and 18% higher than Cisokan. The yield of bothvariants were 4.68 – 7.62 t/ha and 3.24 – 7.83 t/ha, with average of yield was 6.06 and 6.48 t/ha, whereas Cisokanyield was 3.32 – 7.89 t/ha with average of yield was 5.49 t/ha. According to data of turn yield and cross average ofenvironment grow SPR85163-5-1-2-4 line was superior in yield capacity and adaptation then Cisokan. In certainenvironment grow; line S4362f-Kn-2-1-2 had the lower sheet yield than Cisokan and SPR85163-5-1-2-4. Stabilityparameter analyze indicate that all genotype that were tested gave the stable respond to chance of condition in21 environment grow, SPR85163-5-1-2-4 line was more stable than line S4362f-Kn-2-1-2, that was indicated bycontribution of each. Interaction of variant component Genotype x environment (interaction of G x L) for eachcomponent was 15 and 23 %. The line of SPR85163-5-1-2-4 was able to yield 20% higher than line S4362f-Kn-2-1-2 and 26% Cisokan variety at Guguk environment (850 a above se level), while SPR85163-5-1-2-4 line has thebest result until 700 m above sea level.
