Abstract

Tujuan penelitian yakni untuk mengetahui pengaruh waktu aplikasi paclobutrazol terhadap pertumbuhan dan produksi tiga varietas padi sawah. Penelitian dilaksanakan di desa Tanjung Slamat, Medan pada September sampai Desember 2016, menggunakan Rancangan Acak Kelompok Faktorial dengan dua faktor. Faktor pertama dengan tiga varietas (Ciherang, Inpari 3, Inpari 10) dan faktor kedua adalah waktu aplikasi paclobutrazol dengan empat aplikasi, yaitu (tanpa aplikasi, aplikasi 5 hari sebelum inisiasi malai, saat inisiasi malai, 5 hari setelah inisiasi malai). Hasil penelitian menunjukkan bahwa varietas Inpari 10 memiliki jumlah malai terbanyak. Waktu aplikasi paclobutrazol 5 hari setelah inisiasi malai nyata memperpendek panjang ruas 2,3,4. Interaksi penggunaan varietas Inpari 10 dengan waktu aplikasi paclobutrazol 5 hari setelah inisiasi malai nyata memperpendek tinggi tanaman.Kata kunci : paclobutrazol, padi,  varietas, waktu aplikasi paclobutrazol.

Abstract

The growth and production of sugarcane are mainly affected by the quality of seedling, source of bud set material and the use of plant growth regulators as a factor influencing the quality of seedling that is produced so that the amount of production will be affected. The purpose of this research is to obtain the best source of bud set material and auxin concentration for the growth and production of sugarcane. This research was held in a PT. Perkebunan Nusantara II nursery in Tanjung Jati, Kecamatan Binjai Barat (50 above the sea) on July 2016 until April 2017. This research used a randomized block design with two factors, they are the source of bud set material (top stem and under stem material) and auxin concentrations (0 NAA+0 NAAm,100 ppm NAA+25 ppm NAAm, 200 ppm NAA+50 ppm NAAm, 300 ppm NAA+75 ppm NAAm and 400 ppm NAA+100 ppm NAAm). The result of this research showed that the source of bud set materal which is originally from the under stem material was significant increasing the growth of tillers and the stems as well as the source of bud set material that is originally from the top stem material that was really increasing the growth of stem diameter and the number of plant segments. The different auxin concentrations treatment was not significant increasing the growth and production of sugarcane. The treatment interaction of source of bud set material and auxin concentrations was not significant affecting to the growth and production of sugarcane.

Abstract

In order to get a good seed, the source of planting material usually uses 6 - 8 months. Storage of  sugarcane bud set aims to maintain the viability of the seeds as long as the bud set is not ready for planting. This research was conducted on the land of the Agriculture Faculty, University of Sumatera Utara, Medan in April - July 2017, using factorial randomized block design with two factors, i.e. age of planting material (6, 7, and 8 months) and storage periods (24, 48, 72 hours). The results showed that 7 months planting material gave the best plant lenght and seeds diameter. Using 7 months planting material with 72 hours storage periods gave best shoot growth percentage.

Abstract

Corn is one of the indicator plants that can give response to volcanic dust sinabung. The purpose of this study was to determine the respons of sweet corn plant growth to the composition of planting media (top soil, Sinabung volcanic dust and EFBOP). This research was done at experimental field of Agriculture Faculty of University of Sumatra Utara, Medan at height about 25 mals in August until November2016. The research was using a non-factorial randomized block design which was consisting of 6 treatments of top soil : volcanic dust : EFBOP ratio that is 10 kg : 0 kg : 0 kg (M0), 8 kg : 0 kg : 2 kg (M1), 8 kg : 0,5 kg : 1,5 kg (M2), 8 kg : 1 kg : 1 kg (M3), 8 kg : 1,5 kg : 0,5 kg (M4), and 8 kg : 2 kg : 0 kg (M5). Parameters observed were plant height, flowering age, length and width of leaves, fresh weights, length of cob, diameter of cob, seed line in cob, and number of seeds of cob. The result showed that the ratio of top soil, Sinabung volcanic dust and EFBOP had significanly effect on plant height, long and width of the leaves, fresh weights, length of cob, diameter of cob, seed line in cob, and number of seeds of cob, and had no significant effect on age flowering. The best composition of planting media was M2 with composition 8 kg top soil, 0,5 kg sinabung volcanic dust, and 1,5 kg EFBOP.

Abstract

Pengembangan padi lokal saat ini masih kurang mendapat perhatian karena produktivitasnya masih tergolong rendah dibandingkan dengan padi sawah. Padahal, varietas lokal memiliki adaptasi kesesuaian yang tinggi terhadap daerah tertentu, varietas lokal juga perlu dipertahankan dan dilestarikan sebagai kekayaan plasma nutfah, sekaligus sumber keragaman genetik. Salah satu alternatif untuk meningkatkan pertumbuhan dan produktivitas padi lokal adalah dengan pengembangan teknologi penggunaan kompos. Tujuan dari penelitian ini adalah untuk mempelajari pertumbuhan dan produksi dua varietas padi lokal dengan pemberian beberapa komposisi kompos. Untuk itu dilakukan penelitian di Desa Paya Bakung Kec. Hamparan Perak, Kab. Deli Serdang dengan ketinggian tempat ± 25 meter di atas permukaan laut pada bulan Maret hingga September 2016. Penelitian ini dilakukan dengan menggunakan rancangan acak kelompok faktorial (RAK) dengan 2 faktor. Faktor pertama adalah media tanam kompos dengan 5 taraf yaitu: tanpa pemberian kompos (0 kg/plot) ; kompos blotong 3,6 kg/plot; kompos TKKS 3,6 kg/plot; kompos blotong 3,6 kg/plot + kompos TKKS 3,6kg/plot; kompos blotong 7,2 kg/plot + kompos TKKS 3,6 kg/plot; kompos 3,6 kg/plot + kompos TKKS 7,2 kg/plot. Faktor II adalah varietas padi gogo, terdiri dari varietas Sikembiri dan Sigendek-gendek. Hasil penelitian menunjukkan bahwa masing-masing varietas memiliki perbedaan tinggi tanaman sementara perlakuan kompos nyata meningkatkan tinggi tanaman, dan jumlah anakan per rumpun. Kombinasi perlakuan media tanaman (blotong 7,2 kg/plot + TKKS 3,6 kg/plot) pada varietas Sikembiri dan Sigendek gendek menghasilkan rataaan tertinggi dari tinggi tanaman.

Abstract

The problem of generative propagation of soursop is its seeds take a long time to germinate which are caused by the hard seed coat. The solution to solve that problem is scarification and coconut water soaking to simply the process of imbibition and seed germination and also stimulate the growth of shoot. This objective of the research was to determine the effect of the scarification position and the soaking with various concentrations of coconut water on seed germination and growth of soursop seedling. This research was held at the Faculty of Agriculture field, the University of Sumatera Utara in March - July 2017. The research used a factorial randomized block design with two factors and three replication. The first factor is the scarification position (without scarification, stomach scarification, top scarification) and the second factor is coconut water soaking (0%; 25%; 50%; 75 %). The result of the research showed that the germination rate parameter, germination percentage, crop height, number of leaves, root volume and dry weight of crop significantly higher on without scarification treatment than with scarification treatment. The interaction between the scarification position and soaking with various coconut water concentrations was not significantly affecting the seed germination and growth of soursop seedling.

Abstract

One of causes coffee germination process takes a long period of time, because of the caffeine contained in coffee beans can inhibit the activity of amylase enzyme plays a role in the coffee germination process. Therefore, a study was conducted on the provision of Natural Growth Regulatory Substances (Natural PGR). This research was conducted at the Green House, Faculty of Agriculture, Univeritas Sumatera Utara, Medan from October 2019 to January 2020 using a Randomized Block Design (RBD) with two treatment factors : Factor 1 Natural PGR: A0 (water), A1 (bamboo shoot extract), A2 (shallot extract), and A3 (bamboo shoot extract + shallot extract). Factor 2 soaking duration : L1 (6 hours), L2 (12 hours), and L3 (18 hours). The results showed that the application of natural growth regulators (bamboo shoot extract or shallot extract) significantly increase the germination rate and seed vigor index. Soaking durationof 18 hours significantly increase presentation of germination but not different significantly from soaking for 12 hours, but there was no interaction between the two treatment factors. Keywords: Germination, Robusta coffee, natural PGR, soaking duration
