Abstract

ABSTRACT Mustard is one of the agricultural products that interests the community, so it has high commercial potential and value. The use of organic fertilizers in the soil can improve soil properties (physical, chemical and biological properties). This research uses weed as a basic material in making organic fertilizer and inorganic fertilizer. This study aims to determine the effect of inorganic fertilizers and organic fertilizers as well as the single effect of the two fertilizers on the growth and yield of mustard as well as a good dose for mustard plants. The research was carried out in the experimental garden of the Faculty of Agriculture, Sam Ratulangi University, Walian Village, Tomohon City, in August until October 2018 and the Mapanget Balitpalma Laboratory. The experiment used a completely randomized design factorial pattern. The first factor (A) = Fertilizer consists of A0 = 0 kg Phonska / ha and 0 kg Urea / ha, A1 = 200 kg Phonska / ha and 100 kg Urea / ha. The second factor (B) = Organic weed fertilizer (Paitan, Arakan, Kirinyuh) consisting of: B1 = 15 tons of weed / ha organic fertilizer, B2 = 20 tons of weed / ha organic fertilizer, B3 = 25 tons of weed organic fertilizer / ha and B4 = 30 tons of weed / ha organic fertilizer. Every 8 treatments were repeated 3 times to obtain 24 experimental pots. The results showed that there were interactions between inorganic and organic fertilizers on plant wet weight at a dose of A1B1 (200kg Phonska / ha, 100kg Urea / ha and 15 tons of weed organic fertilizer). The results showed that the application of inorganic fertilizers and organic fertilizer as a basis for weeds provided good wet weight of mustard plants. A good dose of fertilizer for mustard cultivation can use 200 kg Phonska / ha, 100kg urea / ha and 15 tons / ha organic fertilizer. Keywords: Mustard, Inorganic Fertilizer, Organic Fertilizer, Weed

Abstract

Duku (Lansium domesticum Corr.) is an important tropical fruit tree in Indonesia, but the supply of uniform and vigorous planting material for orchard establishment remains limited. Polyembryony in duku seeds offers a potential source of clonal seedlings, yet the effects of different polyembryonic seed types and handling methods on seedling vigor are not well documented. This study evaluated early seedling growth of duku derived from zygotic and polyembryonic seeds under farmer managed nursery conditions in Eris Village, North Sulawesi. A randomized complete block design was used with five seed treatments and four replications: zygotic seed with a single embryo (Z1), intact polyembryonic seeds with two embryos (PU2), intact polyembryonic seeds with three embryos (PU3), polyembryonic seeds cut into two sections (PB2), and polyembryonic seeds cut into three sections (PB3). At the end of the nursery phase, number of leaves, plant height, stem diameter, leaf area, and root weight were recorded and analyzed by analysis of variance followed by the least significant difference test at the five percent level. Seed type significantly affected all traits. Zygotic seeds produced seedlings with the highest leaf number, plant height, stem diameter, leaf area, and root weight. Seedlings from cut polyembryonic seeds (PB2 and PB3) showed intermediate performance, with stem diameter and root weight close to those of zygotic seedlings. In contrast, seedlings from intact polyembryonic seeds with three embryos (PU3) had the lowest leaf number, leaf area, and root weight. These findings indicate that zygotic seeds remain the best option for producing vigorous duku seedlings, while sections of polyembryonic seeds, especially PB2 and PB3, can provide acceptable alternatives when zygotic seeds are limited or when clonal propagation is desired.   Keywords: duku; Lansium domesticum; polyembryonic seeds; seedling vigor; rootstock; nursery management
