Abstract

This study aims to determine the effect of several types of mulch on the growth and production of watermelon plants. This research has been carried out in Tuyat Village, Lolak District, Bolaang Mongondow Regency, North Sulawesi. This study was carried out for 3 months from February 2021 - April 2021. This study was compiled using a randomized block design (RAK) with 3 treatments, namely: A = Plastic mulch (black-silver), B = Straw mulch, C = No mulch. Each treatment was repeated 6 times so that there were 18 beds. To determine the effect of the treatment given, observations will be made every 1 week since the plant is 14 days after the plant (HST). Observations include Plant Length and Number of Leaves. Observations made after the plants produce or after harvest are fruit weight and fruit diameter. The results of this study indicate that there are differences between watermelon plants that use plastic mulch, and straw mulch and without using mulch on plant length, number of leaves, fruit weight, and fruit diameter of watermelon plants. The results of this study are expected to provide information to farmers about the effect of using the best mulch when cultivating watermelon plants. Keywords : Watermelon, Mulch, Plant Length, Number of Leaves, Fruit Weight and Fruit Diameter Abstrak Penelitian ini bertujuan untuk mengetahui pengaruh beberapa jenis mulsa pada pertumbuhan dan produksi tanaman semangka. Penelitian Ini Telah Dilaksanakan Di Desa Tuyat Kecamatan Lolak Kabupaten Bolaang Mongondow, Sulawesi Utara. Penelitian Ini Dilaksanakan Selama 3 Bulan Sejak Bulan Februari 2021 sampai dengan April 2021. Penelitian Ini Disusun Menggunakan Rancangan Acak Kelompok (RAK) dengan 3 perlakuan yaitu : A = Mulsa plastik (hitam-perak), B = Mulsa jerami, C = Tanpa mulsa. Masing-masing perlakuan diulang sebanyak 6 ulangan sehingga terdapat 18 bedengan. Untuk mengetahui pengaruh dari perlakuan yang diberikan akan di lakukan pengamatan setiap 1 minggu sekali sejak tanaman berumur 14 hari setelah tanaman (hst). Pengamatan meliputi : Panjang Tanaman dan Jumlah Daun, Untuk Pengamatan yang dilakukan setelah tanaman berproduksi atau setelah panen adalah Berat buah dan Diameter buah. Hasil penilitian ini menunjukan adanya perbedaan antara tanaman semangka yang menggunakan mulsa plastik, mulsa jerami dan tanpa menggunakan mulsa terhadap panjang tanaman, jumlah daun, berat buah dan diameter buah tanaman semangka. Hasil penelitian ini diharapkan dapat memberikan informasi pada petani tentang pengaruh penggunaan mulsa yang terbaik pada saat membudidayakan tanaman semangka.

Abstract

This study aims to determine the characteristics of purple corn F2 and F3 seeds (Zea mays L.) free pollinated Manado Kuning corn with purple corn. The research was carried out in the experimental garden (KP) Pandu, Faculty of Agriculture, Sam Ratulangi University, from July 2019 to October 2019. The research was conducted to describe the growth and yield characters of purple corn obtained from open-pollinated Manado Kuning corn with purple corn using 6 genotypes (cobs) of purple corn, namely: G1 = Genotype 1 purple corn (cob 1), G2 = Genotype 2 purple corn (cob 2), G3 = Genotype 3 purple corn (cob 3), G4 = Genotype 4 purple corn (cob 4), G5 = Genotype 5 purple corn (cob 5), G6 = Genotype 6 purple corn (cob 6). The results of the research on growth components showed that the highest plant height and number of cobs were found in the G5 population (102.71 cm and 1.93) and the highest stem diameter was in the G1 population (2.60 cm). While the yield components in the form of cobs and seeds F3 showed that the highest cob length was found in population G2 (11.57 cm), ear diameter in population G1 (3.17 cm), number of rows of seeds and number of seeds per cob were found in population G5 ( 10.13 and 199.47), the weight of dry cobs with husks and weight of dry cobs without husks were found in the G6 population (51.36 gr and 45.10 gr) and the color of the seeds produced were purple, yellow and white with the percentages respectively 88.11%, 14.82%, 13.28% in population G6, G1 and G3 respectively.Keywords: characterization of corn, purple cornAbstrakPenelitian ini bertujuan mengetahui karakteristik tanaman jagung ungu F2 dan biji F3 (Zea mays L.) hasil bersari bebas jagung Manado Kuning dengan jagung ungu. Penelitian dilaksanakan di kebun percobaan (KP) Pandu Fakultas Pertanian Universitas Sam Ratulangi, pada bulan Juli 2019 sampai dengan Oktober 2019. Penelitian dilaksanakan untuk mendeskripsikan karakter perumbuhan dan hasil jagung ungu yang diperoleh dari persarian bebas (open pollinated) jagung Manado Kuning dengan jagung ungu dengan menggunakan 6 genotipe (tongkol) jagung ungu yaitu: G1 = Genotipe 1 jagung ungu (tongkol 1), G2 = Genotipe 2 jagung ungu (tongkol 2), G3 = Genotipe 3 jagung ungu (tongkol 3), G4 = Genotipe 4 jagung ungu (tongkol 4), G5 = Genotipe 5 jagung ungu (tongkol 5), G6 = Genotipe 6 jagung ungu (tongkol 6). Hasil penelitian pada komponen pertumbuhan menunjukkan bahwa tinggi tanaman dan jumlah tongkol tertinggi terdapat pada populasi G5 (102,71 cm dan 1,93) dan diameter batang tertinggi pada populasi G1 (2,60 cm). Sedangkan pada komponen hasil yang berupa tongkol dan biji F3 menunjukkan bahwa panjang tongkol tertinggi terdapat pada populasi G2 (11,57 cm), diameter tongkol pada populasi G1 (3,17 cm), jumlah baris biji dan jumlah biji pertongkol terdapat pada populasi G5 (10,13 dan 199,47), berat tongkol kering dengan kelobot dan berat tongkol kering tanpa kelobot terdapat pada populasi G6 (51,36 gr dan 45,10 gr) dan warna biji yang di hasilkan yaitu ungu, kuning dan putih dengan persentase berturut-turut 88,11%, 14,82%, 13,28% pada populasi G6, G1 dan G3.Kata kunci: karakterisasi jagung, jagung ungu

Abstract

This study aims to examine the effect of liquid organic fertilizer (POC) on the growth and yield of organically cultivated soybeans and to obtain the best concentration to increase the growth and yield of organically cultivated soybeans. This research was conducted in Sendangan Village, Sonder District, Minahasa Regency. The research design used a randomized block design (RBD) consisting of 5 treatments and 4 replications so that there were 20 plots, namely 0 ml/liter of water (P0), 50 ml/liter of water (P1), 100 ml/liter of water (P2) treatment. , 150 ml/liter of water (P3), 200 ml/liter of water (P4). Variables observed: plant height, number of branches, number of pods, number of root nodules, and production per plot. The results showed that POC had an effect on the number of branches aged 34 and 44 days after planting, the number of root nodules and production per plot. The best POC concentration is achieved at 200 ml/liter of water with the highest value of 225.40 g or the equivalent of 2.25 tonnes.ha -1 Keywords : Soya bean, Liquid Organic Fertilizer,  Concentration.
