Abstract

This research aims to determine the response of watermelon plants to the use of kirinyuh (Chromolaena odorata) green fertilizer. This research was carried out in Benai Kecil Village, Benai District, Kuantan Singingi Regency, Riau Province. The time for carrying out this research is from February to March 2023. The research method used was a non-factorial randomized block design (RAK), namely the dose of kirinyuh green fertilizer (K) consisting of 5 treatment levels. F0 = 100% Artificial fertilizer, F1= 25% Artificial fertilizer + 20 tons/ha Kirinyuh, F2 = 50% Artificial fertilizer + 20 tons/ha Kirinyuh, F3= 75% Artificial fertilizer + 20 tons/ha Kirinyuh and, F4 = No artificial fertilizer and no fertilizer. Each treatment was repeated 3 times so that there were 15 plots, the experiment in one plot consisted of 4 plants, 3 of which were sample plants. Based on the analysis of variance, the application of crunchy green fertilizer had a significant effect on all treatment parameters. The best treatment is found in F3 = 75% Artificial Fertilizer + 20 tons/ha Kirinyuh.

Abstract

The Coelogyne rochusseni orchid, an endemic orchid from the island of Sumatra, has beauty and potential for development. The purpose of this research is to explain the physiological mechanisms in increasing the growth and adaptation of orchid plants at the acclimatization stage using the NFT hydroponic system by spraying thiamine and hyponex fertilizer. The design used in this study was a factorial complete randomized design (CRD) consisting of two factors, spraying thiamine and hyponex fertilizer, each treatment consisting of 4 treatment levels, thiamine 0, 1, 2, 3 mg L-1 and hyponex 0,1, 2, 3 mg L-1. 48 total plantlets analyzed and 3 replicates.  The results of the research on acclimatization of the Coelogyne rachusseni orchid plantlets can be concluded that spraying thyamin and hyponex fertilizer as a single factor significantly affected all growth parameters, plant height (cm), leaf length (cm), number of roots (n),percentage of plantlets life (%) with an optimal concentration of 2 mg L-1 and in terms of interaction factors significantly affected the parameter of Percentage of live plantlets with an optimal concentration being a combination of 2 mg L-1 thiamine and mg L-1 hyponex.
