ABSTRACT
Wheat
(Triticum aestivum L.) is a plant
that grows in sub-tropical areas and is used as one of the world's main sources
of food with high protein and carbohydrate content. The tropical climate in
Indonesia is less suitable for wheat cultivation. The problem of high wheat
imports in Indonesia is due to environmental conditions. Environmental
conditions consist of climatic factors and edaphic factors. These edaphic
factors include soil type and its characteristics. Another factor besides soil
type is nitrogen fertilization. Improper nitrogen fertilization can cause
environmental pollution, soil acidification, and nutrient imbalance. Based on
this, the effort made to increase wheat yield is intensification by applying
the optimal dose of nitrogen fertilizer according to the type of soil used.
This study aims to obtain the interaction of soil type and nitrogen fertilizer
dose that can increase the growth and yield of wheat. The research was conducted in October 2023 -
January 2024 at the Screen house, building C 3rd floor, Faculty of Agriculture
UNS. The research used a completely randomized design (CRD) with two factors,
namely soil type (Andosol, Latosol, Grumusol) and nitrogen fertilizer dose (no
urea fertilizer, 100 kg Ha-1, 200 kg Ha-1, and 300 kg Ha-1). Data obtained were analyzed by analysis of variance at the 5%
level followed by Duncan's Multiple Range Test (DMRT), regression test, and
correlation test. The interaction between grumosol soil without urea fertilizer
gave higher results in the variables of productive tillers, namely 13.33
tillers, total tillers, namely 16.33 tillers, dry weight of stover namely 8.88
grams, number of seeds per clump namely 258 seeds, seed weight per clump namely
7.52 grams, and N uptake of wheat plants, namely 0.17%
