Abstract

The research was aimed to know the characteristics of vegetative and generative of introduction and some local maize 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 maize (Black Aztec, Bisi2, Bonanza). 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 plant, the production per plot. The results showed that the three varieties of maize tested have varying diversity to 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

Abstract

Fast and applicable seed quality testing methods are needed to support the availability of quality seeds that can be distributed. The Tetrazolium Rapid Test Method is a rapid test method that is currently being implemented in Seed Quality Testing Laboratories. Meanwhile, the Radicle Emergence/RE Rapid Test method is currently being developed to accelerate the supply of quality seeds. This research aims to determine a more precise, efficient, and efficient method. Accurate in predicting corn seed germination in the laboratory and field. This research was carried out in the laboratory using a completely randomized design and in the field using a one-factor randomized block design, namely varieties in the form of ten varieties of corn (Sukmaraga, Srikandi Ungu, Srikandi Kuning, Pulut Uri, Lamuru, Bisi 18, Bisi 2, P32, P35, and Betras 1). The results showed that the Tetrazolium Rapid Test and the RE Rapid Test had a very close correlation in estimating the value of Seed Germination in the Laboratory and the Field. Both methods can be used as Rapid Test methods in Seed Quality Testing laboratories. However, the RE Rapid Test is more economical and practical.

Abstract

Penyakit yang sangat penting di perkebunan kelapa sawit adalah busuk pangkal batang yang disebabkan Ganoderma boninense dan merugikan secara ekonomi hampir 43%. Kejadian penyakit akibat G. boninense di perkebunan rakyat telah berdampak terhadap penurunan produksi dan tingkat pendapatan petani juga menurun. Pelaksanaan pengabdian kepada masyarakat dilakukan di desa Tebing Syahbandar Kabupaten Serdang Bedagai Provinsi Sumatera Utara. Tujuan pengabdian untuk meningkatkan pengetahuan kemampuan masyarakat tentang penyakit kelapa sawit yang disebabkan G. boninense. Target yang diharapkan adalah masyarakat mampu mengidentifikasi serangan sejak dini sehingga metode pengendalian dengan cara membumbun atau menggunakan bibit unggultahan G. boninense. Metode pengabdian kepada masyarakat dilakukan melalui ceramah, diskusi, dan kunjungan langsung di perkebunan rakyat. Pelaksanaan pengabdian melalui koordinasi dengan Dinas Pertanian Kabupaten Serdang Bedagai, penyuluh lapangan, serta masyarakat pemilik perkebunan kelapa sawit. Pelaksanaan ceramah dan diskusi bersama tim dosen dan mahasiswa dengan sasaran petani kebun kelapa sawit rakyat.
