Abstract

Lettuce (Lactuca sativa L.) is a vast horticultural plant hydroponics are grown, but improved hydroponic lettuce using Liquid Organic Fertilizer (LOF) is not optimal to replace inorganic fertilizers. The aims of this research are to determine the interaction of giving LOF with the two cultivars of lettuce, to get the optimum concentration of LOF for maximum yield base on the right concentration, and to find out the best cultivars has the best yield. This research was conducted in June to September 2019 at the Agrofarm Hidroponik 55 Cupak Tangah, Water Laboratory of Environmental Engineering Study Program, Instrumentation and Control Laboratory of Agricultural Engineering Study Program, Nutrition and Nonruminant Laboratory of Animal Husbandry Faculty, Andalas University, Padang City. The experiment used a Completely Randomized Design (CRD) consisting of 2 factors, namely lettuce cultivars (Grand Rapid and Green Coral 710) and fertilizer concentration (liquid organic fertilizer and inorganic ab-mix fertilizer) with consisted on 6 levels. There were 12 combinations and 3 replications resulting in 36 treatment units. The data were analyzed statistically using the F test at the 5% level followed by a Dunnett test. The results showed that there was no interaction between type and concentration of fertilizer with the two cultivars of lettuce. LOF being given on the lettuce products height, number of leaves, weights of plant, hardness of leaves lettuce is lower than of the one given inorganic fertilizer but LOF giving products relative level of fiber is similar to the giving inorganic fertilizer. Grand Rapid cultivars has higher and harder than Green Coral but it doesn‟t show a real difference in result on weights, number of leaves and fiber‟s level

Abstract

Several varieties of rice are cultivated in West Sumatra including red rice (Oryza sativaL.) but drought is an obstacle to its cultivation. The purpose of this study was to observe the interaction of red rice with Polyethylene glycol, to determine which genotypes of red rice are ‘drought’ tolerant in the vegetative phase and to see the effect of Polyethylene glycol on the growth of red rice. This research was conducted in the Agronomy Laboratory and Greenhouse, Faculty of Agriculture, Andalas University from October to November 2016. A Complete Random Factorial Design (10 x 2) with 3 replications was used. The first factor was the genotype of the local red rice (10 tested) and the second factor was either with or without Polyethylene glycol. Data were analyzed statistically with the F-test at the 5% level. Significant differences were further tested using Duncan's New Multiple Range Test at the 5% level. The variables observed were: plant height, the number of roots and the length of the longest root penetrating a vaseline/paraffin layer (wax layer method), plant fresh and dry weight and proline content. An interaction between red rice and Polyethylene glycol (20%) was observed. Only genotype 7 “Batu Kangkung” was tolerant to ‘drought’ in the vegetative phase and treatment with Polyethylene glycol affected plant height, length and number of roots penetrating the wax layer as well as the fresh weight of the plant.

Abstract

This study aims to determine the effect of pollination on production of red dragon fruit. The study was conducted from January 2017 to May 2017 at the Aripan Experimental Field, Indonesian Tropical Fruit Research Institute. The treatments used were open pollination and hand cross pollination on 3 accessions of red dragon fruit (Hylocereus polyrhizus) (Sabila Merah, HP-Lbs, HP-01). The number of crosses of each treatment ranged from 20-30 flowers. The results showed that the hand cross pollination on dragon fruit affected the fruit set, fruit weight, fruit length, fruit grade percentage, but did not affect the total soluble solid (TSS) of fruit. HP-01 accession had a percentage of fruit set, fruit weight, fruit length, TSS, and percentage of super and A fruit grade were relatively the same between the hand cross pollination and open pollination. Only several accessions of Hylocereus polyrhizus need hand cross pollination. Keywords : Hylocereus polyrhizus, pollination, production

Abstract

Oil palm has the prospect of rapid development in Indonesia, which causes an increase in plantation area to continue. However, the problem that is still encountered is the low productivity and quality of crop production. The solution that can be used is the use of planting material derived from superior varieties. High-yielding varieties are assembled through hybridization of two varieties that have the desired superior properties. Observation of the flower development cycle is needed as the basis for the hybridization process. Flower development is not only influenced by genetic factors, but also by environmental factors, especially climate. Observations on plant responses are part of a phenological study. This research was carried out in April-August 2021 at Pabatu Gardens, PTPN IV with the aim of observing the flowering phenology of the DxP 540 NG and DxP Socfindo MT Gano varieties. The climatic conditions of the research location during the observation were an average temperature of 29°C, 80% humidity, and an average rainfall of 145 mm/month. The average time required for the DxP 540 NG variety of male and female flowers, the growth phase of the sheath until the outer sheath broke, was 40 days and 38 days, the outer sheath broke until the inner sheath burst was 15 days and 18 days, the inner sheath broke to full bloom was 12 days. days and 16 days, and in full bloom until the flowers are completely pollinated, namely 4 days and 6 days. The average time required for the DxP 540 NG variety of male and female flowers in the growth phase of the sheath until the outer sheath breaks are 32 days and 30 days, the outer sheath breaks until the inner sheath bursts are 16 days and 15 days, the inner sheath bursts to full bloom, namely 11 days and 15 days, and in full bloom until the flowers are perfectly pollinated, namely 4 days and 6 days. The total time required for flowering for the male and female DxP 540 NG varieties was 71 days and 78 days, while for the DxP Socfindo MT Gano variety, male and female flowers were 63 days and 66 days, respectively.

Abstract

The use of quality seeds increase productivity and competitive the success of a potato agribusiness. This study aims to determine the influence of seed size and seed origin paclobutrazol use of growth and production of potato seeds. The research conducted in Berastagi experimental farm, Karo regency, with type of the soil is andisol and altitude of 1,340 m asl. The research was beginning from February to May 2017. The design was used randomize block factorial with 2 replication. The first factor is the size of the seed (U1. small 25 g, U2. medium > 25 - 65 g and U3. large > 65 g). The second factor is the seed origin paclobutrazol use (P0. Control, P1. 7 WAP 250 ppm, P2. 7 WAP 500 ppm, P3. 8 WAP 250 ppm, P4. 8 WAP 500 ppm, P5. 9 WAP 250 ppm, P6. 9 WAP 500 ppm, P7. 10 WAP 250 ppm and P8. 10 WAP 500 ppm. The results showed that large seed size (> 65 g) was more important increasing vegetative growth of potato (plant height and canopy width, leaf area and number of tillers). The seed origin of paclobutrazole given at 8 WAP with dose 250 and 500 ppm have higher crop growth. The highest percentage of total seeds per plot is obtained by using medium size seed with use paclobutrazol 8 WAP 500 ppm (84.22%). Production of potato per plant and per plot was obtained by using medium seeds derived from the use of paclobutrazol 7 WAP 250 ppm (1.15 kg and 13.79 kg).
