Abstract

The purpose of this study was determine whether the application of swallow manure is able to replace the role of urea fertilizer in dry weight and nitrogen uptake of mustard plants on tidal land and to find out whether there is an interaction between manure and urea in dry weight and nitrogen uptake of mustard plants in tidal land . The study was carried out on Jalan Pemuda Km 9.5 Desa Teluk Palingit (Pelundu), Kec. Pulau Petak Kab. Kapuas. The research will start in May 2019 - October 2019. The research design uses Completely Randomized Design (CRD) factorial 2 factors. Factor I: Swallow manure (W) consisting of 4 levels of treatment, namely W0 = control, W0.5 = 0.5 tons ha-1, W1 = 1 ton ha-1, W2 = 2 tons ha-1, and factor II: urea (U) fertilizer consists of U0  = 0 kg ha-1, U25  = 25 kg ha-1, U50  = 50 kg ha-1, U100  = 100 kg ha-1. Each treatment was repeated 3 times, so as to get 48 experimental units. Application of swallow manure 1 tons ha1 can replace the role of urea fertilizer with a dose of 50 kg ha-1 and 100 kg ha-1 in increasing the dry weight and nitrogen uptake of mustard plants in tidal land, and the combination of swallow manure with a dose of 1 tons ha-1 and 50 kg ha-1 urea fertilizer  can increase the dry weight and nitrogen uptake of mustard plants on tidal land.

Abstract

Coffee grounds waste is abundant and its role in plant growth is not widely known.  Therefore, this study applies coffee grounds to Ultisols to find out its role in increasing the growth of mustard greens (Brassica juncea L.) and also improving the chemical properties of Ultisols. This study used a completely randomized design method (CRD) with a single factor of coffee grounds, namely K0 (without coffee grounds), K1 (1 ton ha-1), K2 (1,5 ton ha-1), K3 (2 ton ha-1), K4 (2,5 ton ha-1), K5 (3 ton ha-1), K6 (3,5 ton ha-1), K7 (4 ton ha-1), K8 (4,5 ton ha-1) and K9 (5 ton ha-1).  The parameters observed were pH, exchangeable-Al, N-NH4+, N-NO3- and plant dry weight, then the data analyzed using correlation and regression tests.  The results showed that giving coffee grounds with different doses of up to 5 ton ha-1 did not provide a significant relationship pattern on alteration of pH, exchangeable-Al, N-NH4+, N-NO3- in soil, also in plant dry weight.
