SOME RESPONSE OF CORN VARIETY ON ALUMINUM POISONING IN ADDITIONAL PHASE
No full textNatural factors that often become obstacles in corn production are aluminum (Al) poisoning. Al poisoning is a major limiting factor for plant growth and yield, especially corn plants on dry land that reacts sourly in wet tropical regions. One other alternative that can be done is by using varieties that are well-adapted to the conditions of Al poisoning. Testing of varieties that are resistant to aluminum poisoning can be obtained by testing the germination phase. That’s phase is a fast alternative because it does not require a long time and environmental conditions can be compared to testing until the vegetative and generative phases.This study aims ware to determine the response of several maize varieties on the germination phase of aluminum poisoning. This research was conducted in June 2019 at the Laboratory of Agronomy and Climatology at the Faculty of Agriculture, Tanjungpura University, Pontianak. The experiment used in this study was a single randomized complete design of 5 maize varieties. The treatments used were A = Lamuru, B = Bay Bayur, C = Yellow Srikandi, D = Sukmaraga, E = Bhishma. Observation variables consisted of water content (%), germination (%), vigor index (%), growth rate (% / etmal), root length (cm), plumula length (cm) and normal seed dry weight (g).The results showed that the results of diversity analysis showed that several maize varieties in aluminum stress significantly affected the variable root length and normal seed dry weight, but it did not significantly affect the germination power, index vigor, growth speed, and length of the plumula.

Azwan (1), Tris Haris Ramadhan (2), Sri Rahayu (2) (1) Mahasiswa Fakultas Pertanian dan (2) Staf Pengajar Fakultas Pertanian Universitas Tanjungpura Pontianak ABSTRAK Spodoptera litura Fabricius merupakan hama penting pada tanaman karena mempunyai kisaran inang yang luas. Larva S. litura yang mengakibatkan kerugian pada petani sehingga diperlukan pengkajian lebih mendalam tentang biologi serangga Spodoptera litura. Penelitian ini bertujuan untuk mengetahui siklus hidup, nisbah seks (sex ratio), serta keperidian (fekunditas) serangga S. litura pada kondisi stres pemberian pakan buatan di Laboratorium. Penelitian dilaksanakan selama ±4 bulan di Laboratorium Hama Tanaman S. litura dipelihara dalam gelas plastik (kap es). Pakan yang digunakan ialah pakan yang berbahan Phaseolus vulgaris L. Rancangan penelitian yang digunakan adalah penelitian eksperimen berupa rancangan acak lengkap 1 faktor yaitu terdiri dari 5 perlakuan pemberian pakan buatan dan 50 kali diulang. Hasil penelitian pada pakan buatan Phaseolus vulgaris L dengan jumlah yang berbeda menunjukkan kecenderungan semakin banyak pakan yang dimakan akan memperpendek masa hidup artinya dengan semakin tercukupinya pakan fase hidup serangga cenderung lebih cepat. Pada nisbah sex ratio keadaan makanan tercukupi maka perbandingan antara jantan dan betina akan seimbang, tetapi ketika makanan tidak tercukupi maka perbandingan kelamin pada keadaaan itu hampir seluruhnya terdiri atas serangga jantan. Fekunditas S. litura dipengaruhi faktor kuantitas makanan yang dikonsumsi serangga terhadap proses reproduksinya, semakin banyak jumlah makanan yang dikonsumsinya akan menghasilkan kelompok telur dan jumlah telur yang banyak. Rata rata berat larva menunjukkan masa hidup larva setiap instar yang tercukupi makanannya masa hidupnya semakin cepat. Kata kunci : Biologi, Pakan buatan, Phaseolus vulgaris L., S. litura.
