Abstract

Penelitian ini di lakukan untuk mengetahui respons pertumbuhan dan produksi tanaman kedelai (Glycine Max) terhadap pemberian alelopati lalang ( Imperata cylindrica ) dan babadotan (Ageratum Conyzoides yang di laksanakan di lahan Fakultas Pertanian Universitas Sumatera Utara yang di mulai pada bulan April sampai bulan juli 2017, menggunakan rancangan acak kelompok non faktorial, dengan perlakuan ekstrak alelopati lalang dengan 0, 50, 100, 150 ml dan ekstrak alelopati babadotan dosis 50, 100, 150 ml. Hasil penelitian menunjukan pemberian alelopati babadotan berpengaruh nyata terhadap parameter diameter batang, jumlah polong hampa, jumlah polong berisi, cabang produktif.

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
