Abstract

The experiment was aimed to know how to maintain seed quality during storage by planting black soybean and sweet sorghum in row using an intercropping system. This experiment was conducted in the Laboratory of Seed Technology, Faculty of Agriculture, Gadjah Mada University, Yogyakarta, Indonesia, from November 2013 until April 2014. This experiment was single factor experiment arranged in CRD (Completely Randomized Design) with four treatments and four replications. The treatments consisted of monoculture of black soybean, intercropping between black soybean and sweet sorghum with various row ratios, i.e. 3:1, 4:1, and 6:1. The seeds were stored as many as 250 g for each treatment in hermetic plastic at normal temperature (27-28 ºC) for five months. Seed quality testing was performed every month. Data collected included moisture content, germination, vigor index and vigor hypotetical of the seeds. The result of this experiment showed that the quality of black soybean seeds yielded from intercropping with sweet sorghum gave the same effect compared to the black soy bean seeds yielded from monoculture. Seed quality of black soybean planted in intercropping and monoculture system could be well maintained until the fourth months of storage.

Abstract

Low productivity of corn can be overcome by using fertilizer regularly. Regular fertilization has several benefits, including increasing production and yield quality. Fertilization is divided into organic fertilizers and inorganic fertilizers. Organic fertilizers are fertilizers composed of biological material, one of which is chicken manure. Inorganic fertilizers are fertilizers designed by the fertilizer industry by mixing several high-value inorganic chemicals, one of which is urea. The objectives of research to decide the right combination of doses of chicken manure and frequency of application of urea fertilizer to obtain optimal growth and yield of corn plants. The research was conducted at INSTIPER KP2, Maguwoharjo Village, Depok District, Sleman Regency, Yogyakarta, from August to November 2022. The research design used was factorial which consisted of two factors and organized in a completely randomized design (CRD) with three replications. The first factor was the dose of chicken manure which consisted of three levels, namely control, 87 gram and 174 gram. The second factor was the frequency of application of urea fertilizer which consists of three levels, namely two times fertilization, three times fertilization and four times fertilization. Research data were analysis of variance (Anova) at a significant level of 5%. The research result showed that there was a significant interaction among the application of chicken manure 174 gram and the frequency of application of urea fertilizer four times the fertilization on the parameters of plant height and leaf area. The dose of chicken manure 174 gram significantly increased the growth parameters of plant dry weight and yield parameters of cob weight, cob diameter, weight of 100 large seeds and seed weight. The frequency of application of urea fertilizer four times of fertilization significantly increased the growth parameters of plant dry weight and yield parameters of cob weight, cob diameter, weight of 100 large seeds and seed weight.

Abstract

Salah satu faktor yang menyebabkan masih rendahnya produktivitas jagung dalam negeri adalah pengaplikasian dosis pupuk yang kurang tepat oleh petani. Oleh karena itu, dilakukan penelitian yang bertujuan untuk mengetahui sifat daun, pertumbuhan dan hasil tanaman jagung hibrida pada berbagai dosis pupuk N, yang dilaksanakan pada bulan Januari 2023 sampai Mei 2023 di lahan KP-2 INSTIPER Yogyakarta, Desa Sempu, Wedomartani, Kec. Ngemplak, Kab. Sleman, Yogyakarta. Penelitian dilakukan menggunakan metode percobaan faktor tunggal yang disusun dalam Rancangan Acak Lengkap (RAL) dengan 3 perlakuan dosis pupuk urea sebagai berikut: N1 = 100 kg /ha, N2 = 200 kg/ha, dan N3 = 300 kg/ha. Masing-masing perlakuan terdiri dari 3 ulangan, dan setiap ulangan terdiri dari 3 tanaman. Hasil penelitian menunjukkan bahwa pemberian pupuk urea dengan dosis 200 kg/ha mampu meningkatkan tinggi tanaman, panjang daun, lebar daun, luas daun, jumlah daun, kadar klorofil, panjang tongkol, diameter tongkol, berat tongkol dengan klobot, berat tongkol tanpa klobot, berat kering biji per tongkol dan berat kering per 100 biji. Hasil analisis korelasi parameter jumlah daun berkorelasi positif dengan luas daun (r = 0,96648), parameter kadar klorofil berkorelasi positif dengan jumlah daun (r = 0,89605) dan luas daun (r = 0,97999), parameter jumlah daun, luas daun dan kadar klorofil berkorelasi positif dengan berat kering biji per tongkol (r = 0,71950, 0,87369 dan 0,95303), parameter panjang tongkol berkorelasi positif dengan diameter tongkol (r = 0,94842) dan berat kering biji per tongkol (r = 0,99317).Kata Kunci : Pupuk N, Jagung Hibrida, Sifat Daun.

Abstract

Jagung (Zea mays L.) merupakan salah satu komoditas pangan utama di Indonesia, terutama di beberapa wilayah dijadikan sebagai pangan pokok. Jagung tidak hanya menjadi sumber karbohidrat, tetapi kaya akan komponen pangan seperti serat, asam lemak esensial, isoflavon, mineral, dan antosianin. Cekaman genangan air, terutama pada musim hujan, dapat menghambat pertumbuhan dan hasil tanaman jagung, yang dapat menghambat pertumbuhan serta menurunkan produktivitasnya. Metode yang digunakan dalam penelitian ini adalah percobaan lapangan dengan rancangan faktor tunggal, disusun dalam rancangan acak lengkap (RAL), serta melibatkan dua jenis perlakuan cekaman genangan air, yaitu pemberian penyiraman hingga kapasitas lapang (G1) dan pemberian genangan air selama 15 hari berjarak 5 cm dari permukaan tanah (G2). Setiap perlakuan memiliki 3 ulangan, di mana setiap ulangan terdiri dari 3 tanaman, sehingga secara keseluruhan terdapat 18 percobaan. Hasil penelitian mengungkapkan bahwa cekaman genangan air berpengaruh secara signifikan terhadap perkembangan dan produktivitas jagung. Genangan yang berlangsung selama 15 hari menyebabkan penurunan pada Ketinggian tanaman, ketebalan batang, dimensi daun, serta kapasitas volume akar, serta bobot akar dalam kondisi basah dan kering. Sementara itu, tanaman jagung yang tidak tergenang menunjukkan hasil yang lebih baik di semua parameter yang diamati. Genangan air yang berkepanjangan perlu dihindari karena mampu menghambat proses fotosintesis dan respirasi, terutama pada fase awal pertumbuhan. Kondisi lahan dengan aerasi yang baik diperlukan untuk mendukung pertumbuhan optimal dan meningkatkan hasil tanaman jagung.
