Abstract

The Effect of Rhizobacteria Types and Arbuscular Mycorrhiza Fungi to Potato Yield (Solanum tuberosum L.). Production and productivity of potatoes (Solanum tuberosum L.) in Indonesia is still relatively low compared to other countries. The research aimed to study the effect of interaction between rhizobacteria types and arbuscular mycorrhiza fungi to potato yield. The research was conducted in Laboratory of Microbiology, Faculty of Agriculture, Andalas University and Balai Pengkajian Teknologi Pertanian Sumatera Barat from October 2017 to March 2018. Factorial design with 2 factors in block randomized design was used in the research. The first factor was rhizobacteria isolates (no rhizobacteria, RZ1.L2.4, RZ1.L2.1 and RZ2.L2.1). The second factor was Arbuscular mycorrhiza fungi (AMF) doses (5 g/plant, 10 g/plant and 15 g/plant). The results showed that the interaction between rhizobacteria and AMF did not affect the yield components of potato. The best rhizobacteria isolate was RZ2.L2.1 and 15 g/plant was the best AMF dose for fresh weight of tuber per plant, per plot and per hectare.Keywords: potato, Arbuscular mycorrhiza fungi, rhizobacteria, Solanum tuberosum LABSTRAKProduksi dan produktivitas kentang (Solanum tuberosum L.) di Indonesia secara nasional masih tergolong rendah dibandingkan dengan negara lain.

Abstract

Sidimpuan snake fruit is one of the local specialties of Padangsidimpuan City in Sumatra. The fruit is known for its sweet, sour and astringent taste which differentiates it from Pondoh and Balinese snake fruit. However, snake fruit farmers have been experiencing an increasing failure rate of fruit-set during the off-season which has led to a decrease in production.   Use fertilization and drip irrigation in the off-season has been suggested as a solution. This research investigates the use of these to overcome the failure of fruit set to optimize production of Sidimpuan snake fruit throughout the year by determining the optimal dosage of ammonium sulfate fertilizer and drip irrigation for fruit set and production in the off-season. This research used a split-plot design with the main plot for drip irrigation and the subplot for ammonium sulfate. Observation parameters include the number of flower and fruit bunches, fruit set percentage and a nutrient analysis of the leaves. The results revealed that drip irrigation had a significant effect on the observed variables of fruit set and number of harvested fruit bunches.  Drip irrigation had a significant effect on the fruit set percentage and the number of harvested fruit bunches. The best combination of treatments was also discovered to be 400 g ammonium sulfate fertilizer per plant and drip irrigation 3000 ml/plant. The fertilization period of July-Sept gave an off season harvest that was able to match the fruit set percentage (10.76% difference) and number of fruit bunches that were formed (25.65% difference ) by the April-June fertilization for the on-season harvest demonstrating that drip irrigation and ammonium sulfate can overcome fruit set failure in Sidimpuan snake fruit during the off-season.

Abstract

Potatoes are one of the world's five food crops in the form of tubers and have many benefits. One type of potato developed in Indonesia is red potatoes because they have a high nutritional content and are more susceptible to plant pest organisms. An experiment was conducted in Nagari Selayo Tanang Bukit Sileh, Lembang Jaya, Solok, West Sumatra, Indonesia from May to August 2017. The effect of three indigenous rizobacteria (A2.1b2, A3.1a5 and B1.2a2) and three types of manure, both individually and in combination, on the growth and yield of red potatoes was studied. A two way factorial experiment with a completely randomized design and three replicates was used. Chicken, quail and cattle manure were applied at a dose of 30 tons per hectare. Data were analyzed by analysis of variance and comparison of mean using the Honestly Significant Difference test at the 5% level. There was no interaction between rizobacterial isolates and manure on the growth and yield of red potatoes. All isolates gave similar results with respect to plant growth, but isolates A2.1b2 give the best yields. Chicken manure increased fresh weight of tubers by 11.73 ton per hectare compared to quail and cattle manure.
