Abstract

This study aimed to determine the response of growth and yield of lettuce (Lactuca sativa L). This research was carried out at the Field Laboratory of Experimental Gardens II and the Laboratory of Agrotechnology, Faculty of Agriculture, Halu Oleo University from December 2021 to February 2022. This research was carried out using a Randomized Block Design (RBD) with a single factor consisting of five treatment levels, namely, No Organic Fertilizer Liquid (P0), Liquid Organic Fertilizer 10 ml.L-1 (P1), Liquid Organic Fertilizer 20 ml.L-1 (P2), Liquid Organic Fertilizer 30 ml.L-1 (P3), Liquid Organic Fertilizer 40 ml. L-1 (P4) and each treatment was repeated three times, each replication contained 15 plants, so the total treatment unit was 45 polybags. The variables observed were: plant height (cm), number of leaves (strands), leaf area (cm2), wet weight of plants (g), dry weight of plants (g), wet weight of plant roots (g), and dry weight of plant roots. Each observation variable was analyzed using analysis of variance to determine the effect of treatment. if there is F-count greater than F-table followed by UJBD at a 95% confidence level. The results showed that the liquid organic fertilizer treatment had an effect on the observed variables of plant roots at harvest, which showed that at (10 ml.L-1) is the best concentration by showing the highest average value of lettuce plant growth and yield

Abstract

This study aims to investigate the effect of combining Kinetin and IAA on the growth of kepok banana shoots in vitro. The research was conducted at the In Vitro Laboratory, Agrotechnology Unit, Faculty of Agriculture, Halu Oleo University, from January to April 2023. The study utilized a Completely Randomized Design (CRD) with six treatments: P1 = (Kinetin 1 mg L⁻¹ + IAA 2 mg L⁻¹), P2 = (Kinetin 3 mg L⁻¹ + IAA 4 mg L⁻¹), P3 = (Kinetin 5 mg L⁻¹ + IAA 6 mg L⁻¹), P4 = (Kinetin 2 mg L⁻¹ + IAA 1 mg L⁻¹), P5 = (Kinetin 4 mg L⁻¹ + IAA 3 mg L⁻¹), and P6 = (Kinetin 6 mg L⁻¹ + IAA 5 mg L⁻¹). Each treatment had five replicates, resulting in 30 experimental units, with four Kepok banana shoot explants per culture bottle. The observed variables included shoot emergence time, number of shoots, shoot length, and shoot growth percentage. Results indicated that the combination of Kinetin and IAA concentrations significantly affected the number of shoots and shoot emergence time and shoot length, but did not significantly affect the shoot growth percentage. The best treatment was P2 = (Kinetin 3 mg L⁻¹ + IAA 4 mg L⁻¹) for in vitro growth of Kepok banana shoots.

Abstract

Rhizobacteria have been used for plant growth enhancement. The research was aimed on  finding  the  best  method  of  preplant  seed  treatment through  seed  invigoration plus rhizobacteria as biofertilizer to increase physiological quality of preplant sorghum   seed. The research was undertaken in Agronomy Laboratory, Agriculture Faculty, Haluoleo University, Kendari Southeast Sulawesi.    Research results showed that seed bio- matriconditioning with rhizobacteria was effective in enhancing seed quality of sorghum. The most effective treatment was the integration of seed matriconditioning using rice hull charcoal  or  ‘serbuk  bata  merah’  with  rhizobacteria  Pseudomonas  fluorescens  PG01  or Bacillus spp.CKD061. The seed treatment increased seedling growth by 120% compared to untreated seed. Based on this experiment, rhizobacteria P.fluorescens PG01 or Bacillus CKD061 integrated with   rice hull charcoal or ‘serbuk bata merah’ seed matriconditioning can be used as biological agents in improving seed quality of sorghum. Key words:   bio-matriconditioning, rhizobacteria, seed quality, sorghum
