Abstract


The low availability of Nitrogen nutrients for tomato plants results in disruption of plant growth processes including inhibition of root extension, causing N nutrient uptake to decrease. This study aims to determine the effect of the time of application of Gamal fertilizer (Gliricidia sepium) on the availability of N Regosol and its uptake by tomatoes (Solanum Lycopersicum L). This research is a pot experiment using a completely randomized design method (CRD) with 9 treatments, namely without Gamal and without Inoculant at the same time as planting (G0), Giving Gamal at the same time as planting (G1), Giving Gamal 10 days before planting (G2), Giving Gamal 20 days before planting (G3) and Giving Gamal 30 days before planting (G4). Giving gamal + inoculant at the same time as planting (G5), giving Gamal + inoculant 10 days before planting (G6), Giving Gamal + inoculant 20 days before planting (G7), and giving Gamal + inoculant 30 days before planting (G8). Each treatment was repeated 3 times, so the number of pots was 27. The results were analyzed using a variance at the 5% level, if there was a significant effect, then tested further with the Duncan Multiple Range Test at the 5% level. The results showed that giving Gamal (Gliricidia sepium) at different times affected increasing the available N Regosol and N uptake of tomatoes. The time of giving Gamal + inoculant 10 days before planting significantly gave the best response to the availability of N Regosol and N nutrient uptake of tomato plants.
