Abstract

Rubber is one of the biggest commodity plantation featured in Indonesia. The development of the rubber is centered on the area with precipitation 2500-4000 mm/year. On the area of the rubber exposed to the many problem of competition for land and many attacks of the disease so that need to maximize the potential of the area which low rainfall. But also the area has its own problem especially absorption  hara. One effort that can be to resolve the issue is the giving of mycorrhiza and organic materials to increase absorbtion hara on such plants.This research had been conducted populate plantation in the village of Aek Godang, district of Hulu Siapas, regency of Padang Lawas Utara, North Sumatera. In the month March until Juli 2016. Aimed to the test the influence of mycorrhiza toward absorption of Nitrogen (N) and Phosporus (P) the seeds application of the rubber clone PB 260 on the land with the strees of the drought that has been given organic material. Method of this research was non factorial random sampling block design with three treatments, that was M0: Without Mycorrhiza, M1: Accaulospora 100g/Plant, M2 : Glomus+Acaulospora (1:1) 100g/Plant with every treatment there was 10 replicant of the experiment showed that application mycorrhiza enhanced the increase absorption N and P compared to the not aplication mycorrhiza.

Abstract

Produksi kedelai yang semakin menurun tidak dapat memenuhi kebutuhan kedelai di Indonesia, salah satu penyebab utamanya yaitu semakin sempitnya lahan pertanian. Untuk meningkatkan produksi kedelai di Indonesia dapat ditempuh dengan cara perluasan areal tanam, yaitu dengan memanfaatkan tanah yang berpotensi. Penelitian ini dilaksanakan di rumah plastik Fakultas Pertanian Universitas Sumatera Utara, Medan dengan ketinggian tempat +32 meter di atas permukaan laut dari bulan Agustus 2016 sampai November 2016, menggunakan rancangan acak kelompok dengan 2 faktor perlakuan. Faktor pertama adalah  cekaman kekeringan dengan 3 taraf yaitu KL 80% ; KL 60% ; KL 40% dan faktor kedua adalah pemberian antioksidan dengan 3macam yaitu tanpa antioksidan asam salisilat (500ppm) dan asam askorbat (500ppm). Hasil penelitian menunjukkan bahwa perlakuan cekaman kekeringan berpengaruh nyata terhadap total luas daun, polong berisi pertanaman, bobot kering biji pertanaman, dan bobot kering 100 biji. Perlakuan pemberian antioksidan berpengaruh nyata terhadap parameter klorofil a, klorofil b, jumlah polong berisi per tanaman, bobot kering biji per tanaman, dan bobot kering 100 biji. Interaksi perlakuan cekaman kekeringan dan antioksidan berpengaruh nyata terhadap parameter bobot kering biji per tanaman dan bobot kering biji per tanaman.   Kata kunci : antioksidan, cekaman kekeringan, kedelai

Abstract

WIKA W SYAHPUTRI:Characteristics Study Of The Introduction And Some Local Corn Varieties. Supervised by HOT SETIADO and KHAIRUNNISA LUBIS.The difference in the character of corn plants at different age, would perform different growth, besides the genetic factors also influenced by thecultivation. The high genetic diversity was one of the important factors to produce the new superior varieties.The research was aimed to know the characteristics of vegetative and generative of introduction and some local corn varieties. The research was carried out on the land of the Centre Seed Service of Cash Crops, Departmentof Agriculture,Medan Sunggal, Deli Serdang district, from July 2016 to  October 2016. The randomized block design was used with three varieties of corn (Black Aztec, Bisi2, Bonanza).The data obtained were analyzed and continued with the DMRT. Variables observed were: the plant height, the time of flowering, the time of female flowers bloomed, the time of harvested, the cob length, the number of lines per cob, the production per sample, the production per plot. The results showed that thevarieties significantly affected the plant height, the time of male flower bloomed, the time of harveste, the cob length, the number of line per cob, the production per sample, the production per plot. The Black Aztec showed the lowest production (1005.56 grams per plot) mean while the Bonanza showed the highest production (2338.44 grams). The highest heritability and the broad of diversity coefficient  were obtained in the time of male flower bloomed, the time of female flower bloomed, the time of harvested, the number of lines per cob.Key words: introduction, maize, varieties
