Abstract

The function of plant introductions among others is to obtain new cultivars. After the introduction of plants through the process of adaptation and selection can be used as material crosses with cultivars that have adapted well. A cultivar is said superior when it has a high yield, good fruit quality, resistance to pest attack (plant pests), and able to adapt to various environments grow. The aim of this study was obtain a description, test and compare the yield and quality potential of eight varieties of tomatoes grown in the lowland which are expected to serve as a cross parent material in breeding programs. The experiment was arrange by randomized block design with three replications. The data were analyzed using F-test and the results were significantly midpoint test using LSD test at 5% level. Based on observations on eight strains of local tomatoes and introductions have descripted then selected three strains of tomato introductions which has the form of a round (TM 130804, TM 130805, TM 130806) as well as the introduction of two strains of tomato fruit has an oval shape (TM 130801 and TM 130803 ) that can be used as breeding material further. Keywords : collection, germplasm, tomato.

Abstract

The aim of this research to observe and analyze the ability to grow of watermelon seeds in organic and inorganic fertilizers. Observing and analyzing the interaction between the ability to grow of watermelon seeds with plant growth in organic and inorganic fertilizers. Recommend a combination of organic and inorganic fertilizers that provide maximum results. This research was conducted in field of State Polytechnic of Lampung on June until Agustus 2014. This research uses a randomized complete block design (RCBD) with treatment in the form of thiamethoxam, inorganic fertilizers and organic fertilizers, namely: P1 = 0% organic fertilizer + 100% inorganic fertilizer; P2 = 25% organic fertilizer + 75% inorganic fertilizer; P3 = 50% organic fertilizer + 50% inorganic fertilizer; P4 = 75% organic fertilizer + 25% inorganic fertilizer; P5 = 100% organic fertilizer + 0% inorganic fertilizer. Doses of inorganic fertilizers: Urea = 300 kg.ha-1, SP-36 = 200 kg.ha-1, KCl = 100 kg.ha-1. Organic fertilizer: manure (cow manure) = 20 tons.ha-1. Data were analyzed with analysis of variance and if there is a real different treatments followed by LSD test at 5% level. The results showed that organic and inorganic fertilizer application significantly affected fruit length and fruit weight, but did not significantly affect the ability to grow, main stem length and number of leaves. The length of the longest fruit found in the treatment of inorganic fertilizer application of 75% + 25% organic fertilizer (P2). While the weight of the heaviest fruit found in the treatment of organic fertilizer application of 100% (P5). The highest ability to grow plant found in the treatment of 100% inorganic fertilizer application (P1), treatment of inorganic fertilizer application 50% + 50% organic fertilizers (P3), P2 and P5 treatment. The longest length of main stem found in P5 treatment, while the highest number of leaves found in P2 treatment. Keywords: fertilization, organic, inorganic, watermelon

Abstract

The quality and production of watermelon in Indonesia is low relatively. We introduced "ToPAS" (toping, pruning, arranging and selection), the innovation of cultivation technology in an effort to improve the quality and production of watermelon. Our study was conducted in State Polytechnic of Lampung yield trials from May~August 2014, and used 12 varieties of hybrid watermelons with randomized block design two factors. The results of variance analyses in "ToPAS" system showed that productivity of watermelon fruit (oval and round type) are higher compared with conventional cultivation systems. We suggested using "ToPAS" system in watermelon cultivation to improve the cultivation technology, increasing quality and production of watermelon fruit. ?ToPAS? also suggested for watermelon breeding program.Key word : cultivation, production, ToPAS, watermelon

Abstract

Bunga matahari (Helianthus annuus L.) merupakan tanaman introduksi dari Amerika Utara bagian Timur yang memiliki banyak kegunaan dan manfaat. Bunga matahari paling banyak dimanfaatkan sebagai tanaman penghasil minyak dan tanaman hias. Tanaman ini memiliki keragaman genetik yang besar sehingga dapat dikoleksi sebagai sumber plasma nutfah untuk kegiatan pemuliaan tanaman. Tujuan penelitian ini adalah untuk mengetahui keragaman morfologi empat aksesi bunga matahari. Penelitian ini dilaksanakan di lahan percobaan Seed Teaching Farm Politeknik Negeri Lampung pada bulan Agustus hingga Desember 2020. Penelitian ini menggunakan rancangan acak kelompok faktor tunggal aksesi yang terdiri dari Autumn Beauty (A1), Kanigara IPB (A2), IPB BM1 (A3) dan Teddy Bear (A4). Variabel yang diamati meliputi karakter morfologi yang mengacu pada International Board for Plant Genetic Resources (IBPGR) dan International Union For The Protection Of New Varieties Of Plant (UPOV). Hasil penelitian menunjukkan bahwa ada perbedaan karakter morfologi pada keempat aksesi bunga matahari baik pada karakter kuantitatif maupun pada karakter kualitatif. Keempat aksesi memiliki kemiripan dengan nilai koefisien antara 0,48−0,58.
