Abstracts

This research was carried out at the platic house of the Faculty of Agriculture, Jabal Ghafur-Sigli University, using a completely randomized design (CRD). There are two factors studied, namely variety and nutrient stress, varieties consist of 6 types, those selected from 9 varieties in previous research, while there are 4 types of nutrient stress treatment, namely organic amendments (OA), provided with complete nutrients (CX), phosphorus stress ( P-S), potassium stress (K-S) and magnesium stress (Mg-S). Observations were made on the index and density of stomatal, total chlorophyll content and biomass accumulation. The results of the research showed that the use of varieties and nutrient stress affected the density and index of stomata, total chlorophyll and biomass accumulation. The largest density and index of stomata, the most chlorophyll and the heaviest biomass were found in the Anoman 1 variety and the provision of complete nutrients (V₁CX) while the density and Stomata index, lowest biomass and least chlorophyll were found in magnesium stress and Lamuru varieties. The best combination of treatments was found in the treatment of the Anoman 1 variety with the provision of complete nutrients and the very worst combination occurred in the treatment of the Lamuru variety with magnesium stress (V₆Mg-S). Phosphorus, potassium and magnesium nutrient stress in corn plants grown in ultisol soil can reduce stomatal density and index, total chlorophyte and biomass accumulation respectively by 7.51–37.56%, 5.63 - 18.57%, 16.20 - 24.25% and 4, respectively. 76 – 26.7%, however this reduction can be offset by organic amendments from a mixture of biochar 5 tons ha-1 (75) and crushed rice straw 5 tons ha-1 (75 g).
