PADA BERBAGAI KETEBALAN MEDIA COCOPEAT DAN WAKTU PEMBERIAN NUTRISI SUNDSTROM https://journal.unilak.ac.id/index.php/jip/article/view/1950 ABSTRACT This research purposes know the growth and tubers yield of potato (G0) under various thickness of cocopeat media and time of sundstrom nutrient giving. The research was carried in the screen house in Pandansari, Paguyangan district from October 2014 until January 2015. The research used Randomized Complete Block Design with 2 factor and 3 repetitions. The first factor was the thickness of media with three levels; 10 cm, 15 cm, and 20 cm. The second factor was the time of nutrient solution giving with two levels; once for three days and once for six days. The results of the research showed that the thickness of cocopeat media 20 cm was good for plant height, total of leaves, wide of plant leaves, and improve the roots length 23.6 %. Time of nutrient giving once for three days was good for plant height, total of leaves, wide of plant leaves, weight of fresh plant, weight of dry plant and the result was good for stolon effectiveness (49.84%), weight of fresh tuber (137.85 g), and weight of dry tuber (21.55 g). The treatment of cocopeat medium thickness and time of nutrient giving had not been able to provide increased yield of potato tuber (G0).

The treatment design consists of two factors, namely the defoliation time of the entries and the top graft model. The time of entries defoliation consists of 4 defoliation times, entres defoliation at the connection (W1), entres defoliation 3 days before connection (W2), entres defoliation 6 days before connection (W3), and entres defoliation 9 days before connection (W4). The connection factor model is tested by two connection models, namely, connecting gap (S1), and diagonal connection (S2). The environmental design used is a randomized block design in factorial patterns. Parameters of cacao seedling growth observed were the percentage of live seedlings (%), time of shoot buds (days), shoot length (cm), shoot diameter (cm), and a number of leaf buds (strands). The results of this research are that there is no interaction between the treatment combination of all observed parameters. The best time for defoliation is 9 days before connection. The defoliation model used shows different results that are not real.</em></p> ROSMAITI ROSMAITI, IWAN SAPUTRA Copyright (c) 2019 Jurnal Ilmiah Pertanian https://creativecommons.org/licenses/by-nc-nd/4.0 https://journal.unilak.ac.id/index.php/jip/article/view/1973 Fri, 01 Feb 2019 00:00:00 +0700 OPTIMASI PERTUMBUHAN BIBIT ANGGREK Dendrobium Sp.

Determine the growth of orchid plants, observations were made with the following parameters Growth Percentage (%), Plant Height (cm), Number of leaves (strands), and Number of tillers (stems). Data obtained were analyzed statistically, then continued with the Honestly Significant Difference Test (BNJ) at the level of 5%. The results showed that the single treatment of the use of growing media did not have a significant effect on the parameters of observation of growth percentage (%), plant height (cm), number of leaves (strands), and number of tillers (stems). The growth of growmore fertilizer also did not show a significant effect on the parameters of observation of growth percentage (%), plant height (cm), number of leaves (strands), and number of tillers (stems).
