Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh lama penyimpanan dan konsentrasi Growtone yang dapat meningkatkan pertumbuhan bibit buah naga merah. Penelitian ini dilakukan di lahan percobaan Fakultas Pertanian, Universitas Sumatera Utara dengan ketinggian ±25 m dpl, yang dilaksanakan pada bulan Juni sampai September 2016. Penelitian ini menggunakan rancangan acak kelompok (RAK) dengan 2 faktor yaitu, lama penyimpanan yang terdiri dari, tanpa penyimpanan, 10 hari, 20 hari dan konsentrasi Growtone yang terdiri dari 0 g/l air, 15 g/l air, 30 g/l air, 45 g/l air yang diulang tiga kali. Hasil menunjukkan bahwa lama penyimpanan setek berpengaruh tidak nyata terhadap seluruh parameter pengamatan. Konsentrasi Growtone berpengaruh nyata terhadap parameter bobot segar akar. Interaksi antara lama penyimpanan setek dengan konsentrasi Growtone berpengaruh tidak nyata terhadap seluruh parameter pengamatan. Bibit setek tanaman buah naga dapat disimpan hingga 20 hari sebelum ditanam dengan menggunakan Growtone dengan konsentrasi 7,75 g/l air untuk meningkatkan pertumbuhan tanaman buah naga.

The aimed of the research was to determine the effect of application of Steinernema sp. to control H. hampei. This research was conducted at the Laboratory of Plant Disease, Faculty of Agriculture, University of Sumatera Utara, Medan at an altitude of ± 25 meters above sea level, from November 2014 to  April 2015. The research used Complete Randomized Design (Non Factorial) with various nematodes level. They were N0 (No nematode/control), N1 (68 JI / ml), N2 (138 JI / ml), N3 (208 JI / ml). The parameters observed were the symptoms of an attack and the percentage of mortality H. hampei. The results showed that the best result to control H. hampei was showed on treatment N3 (208 JI / ml) with a percentage of mortality by 82 % .

Abstract

Golden snail (Pomacea canaliculata L.) able breed quickly at flood area and hold out at 6-8 weeks at dry condition. Modification of  water heights and concetrations of mollucicides are be expected decrease the population of golden snail (Pomacea canaliculata L.). This research was studied at paddy field of Tanjung Mulia Village, Tanjung Morawa District from April 2016 until August 2016. This research used completely randomized design with two factors consist of water heights of paddy field (H) such as, 0 cm; 2,5 cm; 5 cm and consetrations of mollucicides (M) such as, 0 g/15L water;100 g/ 15L water; 300 g/ 15 L water. Combinations treatment are repeated at three times and there are 27 treatments. The results showed the decreasing of water heights at paddy field can decre the population of golden snail (Pomacea canaliculata L.) and dry grain weight brutto; application of mollucicides showed response about golden snail (Pomacea canaliculata L.) and many parameters of rice; combination of decrease water height in paddy field and consetration of mollucicides did not show response about golden snail (Pomacea canaliculata L.) and many parameters of rice.   Key words : golden snail, height water, mollucicides

The objective of the research was to determine the different of growth and development of some cassava genotype. The research was conducted at Desa Tanjung Selamat, Kecamatan Sunggal, Kabupaten Deli Serdang from July to December 2016. The research was arranged by Randomized Block Design for one variety (Adira-1) and 6 genotype (Valencia, Malang, Malaysia, Lampung, and Putih) each treatment was replicated 4 times.The result showed that Pulut genotype has the highest average plant heigth (277,48 cm) that is significantly different from the others accept Malang genotype, Malang genotype has the highest average diameter (31,26 mm) wich is significantly different from the others. The highest Lobus length character is at Pulut genotype (22,6 cm) and the highest lobus wide is at Malang genotype (7,3 cm). The highest leaf length petiole character is at Putih genotype (31,4 cm), and the highest of  leaf lobus character at Adira 1 and Lampung genotype are 5 leaves lobus. There are was different among genotypes (Valencia, Malang, Malaysia, Lampung, and Putih) and variety (Adira-1) on the average weight of (6 month after planted) cassava.

Abstract

The purpose of this research was to determinate the growth response of embryogenic callus from some varieties of soybean (Glycine max (L.) Merrill) on hypoxic and in vitro condition. The research was conducted at The Tissue Culture Laboratory of Agriculture Faculty in University of Sumatera Utara on April until December 2016. This research had two stages, induction of embryogenic callus and analysis metabolism of callus after hypoxic condition with t-test. This analysis used factorial Completely Randomized Design with two factors. The first factors were varieties of soybean and the second factors were combination of Plant Growth Regulator (PGR) (5 mg/l 2,4-D + 1 mg/l BAP, 10 mg/l 2,4-D + 1,5 mg/l BAP, and 15 mg/l 2,4-D + 2 mg/l BAP). The result showed the varieties, combination of PGR, and interaction of varieties and PGR give significant effect to weight callus. The result of T-test showed that in hypoxic condition, POD enzyme exercise on Gepak Kuning’s callus in 5 mg/l 2,4-D + 1 mg/l BAP was different before and after hypoxic condition. Keywords : 2,4-D, BAP, embryogenic callus, hypoxic, soybean
