Pengaruh Pupuk Organik Padat dan Varietas pada Produktivitas Tebu (Saccharum officinarum L.)

Abstract

Sugarcane is one of the main sugar-producing commodities in Indonesia. The one of the efforts to increase the production and yield of sugarcane can be done by fertilization using organic fertilizer and the use of improved varieties. The aim of this research are to get optimal rate of solid organic fertilizer, the best sugarcane variety, and interaction between solid organic fertilizer rate and variety on productivity of sugarcane. The study was conducted in December 2015 until December 2016 at Teaching Farm and Chemical Analysis Laboratory, State P olytechnic of Lampung. The research used Factorial Random Block Design method, with two factors. The first factor is the rate of solid organic fertilizer (Control, 1.000 kg.ha-1 , 1.500 kg.ha-1 , and 2.000 kg.ha-1), whereas the second factor is sugarcane varieties (GMP 3, GMP 19, and SS 57). The data of the research were analyzed by analysis of variance and if the result was significantly different then continued by using LSD test of 5% level. The results showed that there was interaction between the use of solid organic fertilizer 1000 kg.ha-1 and GMP 3 varieties on variable length of sugarcane stem. The productivity of sugarcane crops can be improved by the application of 1000 kg.ha-1 solid organic fertilizer which influences the variables of sugarcane quantity per lube and the number of sugarcane segments. The best variety that can be used to increase the productivity of sugarcane is GMP 3.

The Effect of Maturity Level and Size on The Viability of Cinnamon Seeds at Different Storage Time Periods (Cinnamomum burmanii. L)

“…According to (Cahyani et al, 2016) vegetative growth in the event of a water shortage will greatly affect all aspects of plant growth, including physiological, biochemical, anatomical, and morphological processes. If there is a lack of water, some of the leaf stomata will close, so CO2 will be inhibited as a result of photosynthetic activity.…”

Analisis Faktor-faktor Produksi Usahatani Tebu di Desa Banyuputih Kecamatan Banyuputih Kabupaten Situbondo

“…Hasil ini menunjukkan bahwa pemberian pupuk urea secara nyata berkontribusi terhadap pertumbuhan tanaman tebu, yang dapat berdampak pada peningkatan atau penurunan produksi tebu. Temuan ini mendapatkan dukungan dari hasil penelitian lain, seperti yang disampaikan oleh Ayu et al (2017), yang menyatakan bahwa pupuk urea berpengaruh pada produksi tebu melalui peningkatan ketersediaan nitrogen bagi tanaman. Karena tanaman tebu membutuhkan nitrogen dalam jumlah besar untuk mensintesis protein dan memengaruhi proses fotosintesis, di mana protein memiliki peran utama dalam pembentukan struktur dan jaringan tanaman.…”

Respon pertumbuhan bibit tebu pada pemberian pupuk organik cair asal nasi basi

“…Hal tersebut diduga karena POC mengandung unsur hara terutama hara makro yang rendah dan sifat kelarutan hara yang lambat tersedia. Hal ini sejalan dengan hasil penelitian [13] yang menyatakan bahwa pemberian pupuk organik padat dengan dosis yang berbeda menghasilkan bobot tebu per kairan yang tidak berbeda dengan perlakuan kontrol. Selain itu, juga diduga karena adanya pengaruh media tanam yang digunakan, yaitu jenis tanah regosol [14].…”
