The objectives of this research was leaning and finding the consentrade of IAA (Indole Acetic Acid) on vegetative growth of Phalaenopsis sp. The research used a randomly completely block design consisting of five treatments on level IAA consentration : 0 mg/l (A0), 100 mg/l (A1), 200 mg/l (A2), 300 mg/l (A3) and 400 mg/l (A4). Every treatment was replicated five times. The observed parameters included the amount of increasing leaves, the length and width of lives, the amount of increasing roots and the length of increasing roots. The results showed that the consentrade 400 mg/l IAA was the most appropriate consentrade to stimulated on vegetative growth of Phalaenopsis sp. The length of increasing leaves was 0,93 cm and the amount of increasing roots was 3,90

The performance of improved sweetpotato clones (Ipomoea batatas (L.) Lamb) in two location reported in this studies. The first location at Jatikerto-Malang Regency, from March to August 2012 and second at Sambigede-Blitar Regency, from April to September 2012. Both of the trials were done with a randomized complete block design with 3 replications. The experimental material consisted of nine sweetpotato clones. All the clones were planted in a plot size 5 m x 5 m, consisted of four rows with 75 cm between the rows, 25 cm spacing between plants within the row. The experimental plots received 100 kg N, 20 kg P2O5, and 75 kg K2O/ha in the form of Urea, SP-36 and KCl. Roots were harvested four months after transplanting. Fresh storage root yield and protein content presented in this report. Fresh storage root yield is significantly influenced by location, among improved clones ranging 7 to 21 t/ha in Malang and 5 to 18 t/ha in Blitar, two clones of them to reach 114 to 161% higher to control variety, Boko. On the contrary with protein content is not sensitive on differ locations, among improved clones ranging 6 to 7,63% dry weight basis

Problems faced by dryland maize include less available water, erosion, soil structure-degradation, low organic matter content and other chemical elements. This experiment was carried out to elucidate the effect of manure application on the growth and yield of maize under water limited condition. The research was conducted in a glasshouse of Tribhuwana Tunggadewi University, Malang having altitude of 505 m above of sea level and the predominance soil type is an Andisol. The experiment used Randomized Block Design Factorial with two factors and three replicates. The first factor was manure application, consisting of: control (PO), chicken manure 15 t/ha (PI) and cow manure 15 t/ha (P2) treatments. The second factor was water volume consisting of: 150 mm/season (Al), 300 mm/season (A2) and 450 mm/season (A3) treatments. The results showed that there was a strong interaction between manure application and water volume in affecting grain dry weight per plant and plant total dry weight on harvest. Application of 15 t/ha chicken manure combined with 300 mm water volume/season gave the best yield compared to cow manure and control that each combined with 300 mm season water volume treatment

Rice continuous planting without additional biomass application decreases soil fertility and nutrient stability in the soil. Different kind of legumes crops in the tropic is one of possibility can used an organic fertilizer. The aims of this study was to evaluate legume crops as organic matter, and kind of legume crop potentially has high nutrient in the soil after rice harvest and be continue used by following crops. To evaluate additional organic matters to increased yield of rice. The study was conducted from July to November 2013 at Amadanom village, sub district of Dampit and Malang district. Split plot design was used with three (3) replication and two (2) factor. Main plot consist of N0 (no addition an organic fertilizer), N1 (N an organic fertilizer 30 kg/ha), N2 (N an organic fertilizer 60 kg/ha). Sub plot additional organic matters 20 t/ha consist of : B1 (biomass of Crotalaria juncea L.), B2 (biomass of Sesbania rostrata) and B3 (biomass of Tithonia diversifolia). The result showed that additional biomass Sesbania rostrata and N an organic fertilizer 30 kg/ha increased yield by 104,98%. The high contribution on nutrient content in the soil and application of biomass Sesbania rostrata. It was concluded that organic matter of Sesbania rostrata was effective as organic fertilizer to increased soil fertility and rice yield

UJI KONSENTRASI IAA (INDOLE ACETIC ACID) DAN BA (BENZYLADENINE) PADA MULTIPLIKASI PISANG VARIETAS BARANGAN SECARA IN VITRO Ricky Indri Hapsari; Astutik Astutik

A study that was aimed to determine the effects of IAA and BA concentrations on number of shoot at multiplication phase of barangan banana, was conducted at Plant Tissue Culture Laboratory of Tribhuwana Tunggadewi University from October 2007 to January 2008. Treatment combinations of three levels of IAA, i.e. 0,0 mg/l; 0,15 mg/l and 0,30 mg/l, and three levels of BA, i.e. 4,0 mg/l; 4,5 mg/l and 5,0 mg, were arranged in a completely randomized design with three replicates. Results of this study indicated that there was interaction effect of IAA and BA to shoot variable at 6, 8, 10 and 12 weeks after sub culture application. Combination of concentration IAA 0,0 mg/l and BA 4,0 mg/l (I0 B1) achieved highest shoot number. But there was no significant effect of I0B2 and I1B3 treatments. The fastest shoot growth was observed for application of BA 4,0 mg/l, and BA 4,5 mg/l

The objective of this experiment was to isolate Rhizobium bacteria from soybean and to study the effect of inoculation of the isolated indigenous bacteria on soybean growth. Six treatments comprising TA (Entisol control), TaI1 (Entisol+Rhizoplus), TaI2 (Entisol +Rhizobium indigenous), KB (Inceptisol control), TbI1 (Inceptisol+Rhizoplus), TbI2 (Inceptisol+ indigenous Rhizobium) were arranged in a completely randomized design with three replicates. Results of this study indicated that; (1) morphology of Rhizobium was shape of colony, around white, and phlegm, total colony of Rhizobium indigenous are 130 x 107 cuff/ml (2) indigenous Rhizobium had higher influence than Rhizoplus to the total of the root-nodule, the weight of dry nodule, the high of the plant, and pH, the N-total of soil, and the N-total of plant are good at an Entisol and an Inceptisol

This study aimed to determine the response of lettuce plants to type planting media and watering intervals in the verticulture system. This research method used a split-plot design with eight treatments and three replications, including Main plots P1 (2 days watering interval) and P2 (4 days watering interval). The second treatment as sub-plots consisted of planting media: M1 (soil: manure), M2 (manure: sand), M3 (manure: husk charcoal), and M4 (soil: manure: husk charcoal). Observations included growth parameters (plant height, number of leaves, leaf area) and harvest parameters (total fresh weight of plants, fresh weight of roots, total dry weight of plants, dry weight of plants without roots, dry weight of roots). The result of the 2nd watering interval was able to significantly increase the growth component and fragrant lettuce plants compared to the 4th watering interval. Different types of planting media showed a significant effect on plant height but did not affect the number of leaves, leaf area, and components of the yield of fragrant lettuce.
