Abstract

Local tobacco has an important role in the kretek cigarette industry in Indonesia, because 80% of kretek cigarettes are made using local tobacco. However, in some areas, the quality of local tobacco remains low due to inefficient fertilisation. Using slow-release fertiliser can increase the efficiency of nutrient uptake by plants. This Research aims to examine the use of biochar-based slow-release fertiliser on the morphological characteristics of tobacco plants. The Research method was a field experiment using a randomised block design to test the SRFbiochar SP36 fertiliser treatment. The treatments tested were SRFbiocharSP36 as basic fertiliser, SRF-BiocharSP36, SRF-biocharSP36+Cow urine and SRF-BiocharSP36+Cow urine+Azotobacter on tobacco morphological characters, including: plant height, number of leaves, stem diameter, flag leaf angle and wet weight of tobacco leaves. The Research found that SRF-BiocharSP36, used as a basic fertiliser, produced the best results and significantly affected plant height (68.60 cm) and stem diameter (19.39 mm). Apart from that, this formula gave the best results for the number of leaves (24) and the wet weight of leaves (44.92 g).

Abstract

The dependence of tobacco farmers on synthetic chemical fertilizers for many years has led to a decline in soil quality and crop yields in the long term, One of the main challenges in tobacco production is to produce quality seeds that can optimally support crop productivity. The research method used a random design of a non-factorial group, each treatment consisted of 3 treatments tested, namely 4 combinations of planting media, namely P0 (Control), P1 (Azotobacter), P3 (Biohumic), P4 (Azotobacter+Biohumic). The results obtained in this study showed that the best results in the combination treatment of azotobacter and biohumic consistently gave the best results on all plant growth observation parameters, this shows a significant synergistic effect between nitrogen fixation by azotobacter and increased nutrient availability by biohumic

Abstract

This study aims to evaluate the best growing medium for the mycelium growth of F1 oyster mushroom (Pleurotus ostreatus) seeds using millet flour as a nutritional supplement. A Completely Randomized Design (CRD) was applied with two factors: the type of growing medium (corn, sawdust, rice husks) and the concentration of millet flour (0%, 25%, 50%, 75%). Observed variables included mycelium growth (cm), mycelium density, and daily growth on the 7th, 14th, and 21st days after inoculation. The results indicated that corn without millet flour (J1P0) produced the best mycelium growth, while adding 25% millet flour to corn (J1P1) and sawdust (J2P1) enhanced mycelium density. However, higher millet concentrations (50% and 75%) tended to reduce growth efficiency due to excessive moisture content. This study recommends using millet flour at low concentrations to improve the efficiency of sustainable F1 oyster mushroom seed production.
