Abstract

Sandy coastal area is a poor land, with minimal nutrients and low ability to store water and nutrition. Therefore, plant is difficult to grow well, consequently the treatments for improving sandy coastal is required before planting to support their growth. Application of Trichoderma as a plant-growth promoting and controlling pathogens had been known. Shallot seed treatment by Trichoderma agents was intended to improve and support plant growth and yield in the sandy coastal land. The aim of experiment was to determine the most effective treatment to improve growth and yield of shallot on sandy coastal land. The experiment had been carried out in Yogyakarta during August - November 2015. The factorial treatments of cultivar and Trichoderma applications were arranged in Completely Randomized Design with three replications. The shallot cultivars consisted of Tiron, Crok, and Biru, while Trichoderma application consisted of control (no treatment), sprayed with Trichoderma, soaked in Trichoderma, matricontioning media i.e. rice husk charcoal and brick in combination with Trichoderma. The collected data related to plant growth and yield. The result showed that seed treatment methods with Trichoderma increased the plant height, the leaf area index, extensive root, net assimilation rate (NAR), plant growth rate (PGR), Nitrate Reductase Activities (NRA), total chlorophyll, and fresh bulb weight. The best technical treatment for cultivar Tiron was soaked with Trichoderma, and Crok was sprayed with Trichoderma, while Biru cultivar was using brick in combination with Trichoderma.

Abstract

This research was aimed to examine and get biomatriconditioning technique that increase viability and seed vigor rice (Oryza sativaL.). This research was conducted at Agronomi Unit of the Laboratory Agrotechnology of Haluoleo University, Kendari from January until March 2013. This research used completely randomized design with factorial. The first factor was the variety: Konawe and Inpari 10, the second factor was biomatriconditioningtechnique Control, Bacillus CKD061+Husk Charcoal Powder, Bacillus CKD061+Powder Red Brick. Serratia CMN 175 + Husk Charcoal Powder, Serratia CMN175+Red Brick powder. For the all numbers there were 14 combination treatments, repeated for 3 times, so the total of experimental units were 42. Replication consisted of 5 polybag so there were 210 plants. Data were analyzed using a manner sidik, followed by Test Honestly Significant Difference. The results showed that the best biomatriconditioning for Konawe varieties was Serratia CMN175 + rice husk powder treatment, while for the Inpari varieties 10 Bacillus CKD061 + husk powder for the both of treatment could be able to improve simultaneity grow, vigor index, relative growth speeds, T50, plant height and number of tillers.Keywords: Bacillus CKD061, P. fluorescensPG01, seed of rice, Serratia

Abstract

The objective of this research was to evaluate the effect of seed invigoration on improving seed viability and vigor, and to overcome problems of postharvest physiological dormancy of upland rice seed. The research was conducted from February to June 2011 at Agrotechnology Laboratory, Faculty of Agriculture, Halu Oleo University. The experiment used randomized complete design which consisted of 13 treatments, i.e control (G0), Hidration-Dehidration (G1), Matriconditioning using ground brick (G2), Matriconditioning using ground burned-rice husk (G3), Bacillus CKD061 (G4), P. fluorescens PG01 (G5), Serratia CMN175 (G6), Biomatriconditioning using ground brick + Bacillus CKD061 (G7), Biomatriconditioning using ground brick + P. fluorescens PG01 (G8), Biomatriconditioning using ground brick + Serratia CMN175 (G9), Biomatriconditioning using ground burned-rice husk + Bacillus CKD061 (G10), Biomatriconditioning using ground burned-rice husk + P. fluorescens PG01 (G11), Biomatriconditioning using ground burned-rice husk + Serratia CMN175 (G12). Each treatment was replicated three times, therefore, overall there were 36 experimental units. Data obtained were analyzed using analysis of variance and followed with Duncan’s Multiple Range Test. The research results showed that bio-invigoration treatments integrated with rhizobacteria were effective to overcome the problems of postharvest physiological dormancy when local upland rice seeds were harvested. In addition, this treatment was also able to increase viability and vigour of the seed. Among treatments tested, the use of Bacillus sp. CKD061 or P. fluorescens PG01, either independently or integrated with matriconditioning using ground brick or ground burned- rice husk was more effective in improving viability and vigour of local upland rice seed compared to other treatments.

Abstract

Penelitian bertujuan untuk mengetahui efektivitas pemberian hara mikro melalui akar dan daun. Penelitiandilaksanakan dengan menggunakan Rancangan Acak Lengkap (RAL) faktor tunggal. Perlakuan berupa kontrol,pupuk mikro lewat media, pupuk mikro lewat daun. Masing-masing perlakuan diulang 6 kali. Media tanam berupapasir yang sudah dimasukan ke dalam bak penanaman, setelah itu tanam benih kangkung dengan jarak 10x10 cmpada setiap bak. Lalu aplikasikan pupuk melalui media atau daun seminggu sekali. Pengamatan yang dilakukanmeliputi tinggi tanaman dan kehijauan daun dengan SPAD 502 untuk tiap minggunya; aktivitas nitrate reduktase,kandungan klorofil a, klorofil b, dan klorofil total, bobot kering batang, bobot kering tajuk, bobot kering daun,bobot kering akar, luas daun (LD), serta analisis pertumbuhan tanaman, meliputi nisbah laju daun (NLD), luasdaun khas (LDK), bobot daun khas (BDK). Berdasarkan penelitian yang telah dilakukan, pemberian pupuk cairmelalui media maupun daun belum mampu meningkatkan pertumbuhan dan hasil tanaman kangkung. Perlakuanpada daun cenderung menunjukan hasil yang lebih tinggi dibandingkan perlakuan pada media pada semuaparameter pengamatan.Kata kunci: efektivitas, hara mikro, akar dan daunABSTRACTThe aim of this research is to know the effectiveness of micro nutrient giving through root and leaf. Theresearch was conducted by using Completely Randomized Design (CRD) of single factor. Treatment of control,micro-fertilizer through the media, micro-fertilizer through the leaves. Each treatment was repeated 6 times.Planting media in the form of sand that has been inserted into the tub of planting, after that plant the seeds ofkangkung with a distance of 10x10 cm in each tub. Then apply the fertilizer through the media or leaves once aweek. Observations included plant height and greenery of leaves with SPAD 502 for each week; nitrate reductaseactivity, chlorophyll a, chlorophyll b, and total chlorophyll, dry weight of stalk, dry weight of canopy, leaf dryweight, root dry weight, leaf area, and plant growth analysis, including leaf rate ratio, typical leaf area, typicalleaf weight. Based on the research that has been done, the application of liquid fertilizer through the media andleaves has not been to increase the growth and yield of kangkung. Treatment on the leaves tend to show higherresults than treatment on media at all observation parameter.Keywords: effectiveness, micro nutrients, roots and leaves

Abstract

This study aims to determine the effect of soaking duration of shallot bulbs using Local Microorganisms (MOL) on seed viability and vigor during the early growth phase. The research was conducted at the Agrotechnology Laboratory, Unit Stiper Petra Baliem Wamena, from April to August 2018 using a Completely Randomized Block Design (CRBD) with six MOL soaking duration treatments: 0 minutes (control), 30 minutes, 60 minutes, 90 minutes, 120 minutes, and 150 minutes, each repeated four times. The observed parameters included germination percentage, maximum growth potential, growth rate, plant height, and number of leaves at 14 days after planting (DAP). The results showed that MOL soaking treatments influenced the viability and vigor of shallot seeds. The highest germination percentage was obtained at the 60-minute treatment (95%), while maximum growth potential was relatively uniform across almost all treatments (100%). The highest growth rate was observed at the 150-minute soaking duration (85.57%), whereas the control treatment produced the lowest value (57.23%). Early vegetative growth also showed the best response at the 60-minute treatment, with plant height reaching 7.50 cm and the number of leaves reaching 10.75 at 14 DAPS.
