THE ROLE OF BIOCHARCOAL FROM RICE LIQUID AND COMPOST FROM RICE STRAW ON YIELD OF RICE (Oryza sativa L.) IN POLYBAG. The aim of the research was to determine the role of rice husk biochar and rice straw compost on polybag rice yield. The combination of treatment during dosing of rice husk biochar and rice straw compost at a ratio of 10:10 t ha-1 produced a better root system (root-to-canopy ratio).
Application of rice husk biochar at 9.1 t ha-1 resulted in slow flowering of rice. Treatment of rice straw compost at a dose of 8.9 t ha-1 gave the highest yield of rice ha-1. The role of rice husk biochar and rice straw compost on rice yield should be considered.
Effect of rice husk biochar and rice straw compost on post-harvest chlorophyll content (units). We followed the results of the regression analysis of the influence of rice husk biochar on the root-to-crown ratio in three levels of rice straw compost dosage.

Notes: Numbers followed by the same signs in the combined treatment are not significantly different (p < 0.05) by HSD test at 5% significant levels. 5], was known to increase the components of rice yield, namely the number of rosettes, productive rosettes, number of grains with a higher level of biochar application. The increase in yield in the form of dry rice is due to the increase in the availability of phosphate nutrients, which plays a decisive role in the filling process of rice seeds, which is also in accordance with the statement of Goyal et al.
33], who showed that the increase in soil pH is due to the mixing of organic acids with aluminum and iron ions in the soil solution through a chelation process, which indirectly increases the availability of phosphates. 34], who showed that fulvic acid, originating from the decomposition of organic matter, plays a greater role in the release of phosphate elements into the soil solution. The effect of rice husk biochar, which can slowly release nutrients, will determine the availability of nutrients during the plant growth period, which is shown by the harvest index.

Rice Yield per Hectare
A low rate of carbohydrate synthesis causes a decrease in plant matter dry weight, where plant matter is one of the plant's indicators of photosynthesis rate. 37] who stated that light intensity levels can have a significant effect on photosynthetic rates, which are directly related to a plant's ability to grow. There is a tendency that the application of organic fertilizers that have been decomposed effectively increases rice growth and yield [39].
The nutrient content of N, P and K in rice straw compost is relatively high with a low C/N ratio, so they can be directly used as organic fertilizer that plays a role as a nutritional source for the crop. It is expected that the application of rice straw compost can improve the physical, chemical and biological properties of soil that can be obtained through the application of inorganic fertilizers. The effect of applying organic fertilizers to the soil, especially rice straw compost, granulator of areas (improvement of soil structure), source of macro and micronutrients, increasing the WHC of the soil, increasing the ability of the soil to absorb nutrients (CEC of the soil becomes high) and as an energy source for soil microorganisms [41].

In the manuscript, the authors mainly focus on determining the optimal dosage of rice husk biochar and rice straw compost for rice yield. In the results and discussion, it is suggested to include visual results of the grown rice in polybag and provide some discussion on the physical appearance. Y Composition of soil used, rice husk biochar and rice straw compost were mentioned in the first paragraph of.
In subheading 2.2 of materials and methods, we have added working procedures for the processing of biochar from rice husks and compost from rice straw. Yes, inorganic fertilizer is still used for rice plants and is listed in the last paragraph of Subheading 2.5 Materials and Methods. Rice husk biochar had a significant effect on flowering age, but rice straw compost did not.
We explained only that significant effect. regression in the treatment of rice husk biochar that. significant effect on flowering age. Y In fact, many effects of rice husk biofuel and rice straw compost on soil properties and plant response, which are applied by biochar and fertilizer. Y We have written in a subtitle of 2.6 for data parameters with clarity in materials and methods.

The aim of the research was to determine the role of rice husk biochar and rice straw compost on bagged rice yield. The results of the research showed that a dose of rice husk biochar of 12.5 tons ha-1 resulted in higher chlorophyll content in rice leaves. A treatment combination between a dose of rice husk biochar and rice straw compost at a ratio of 10:10 ton ha-1 produced a better root system (root-to-canopy ratio).
The dosage of rice husk biochar at 9.1 tons ha-1 ensured that the flowering time of the rice was slow. Rice husk biochar had no direct effect on rice yield, but the role of rice straw compost at a dosage of 8.9 tons ha-1 produced the highest rice yield per hectare. The effect of rice husk biochar and rice straw compost on rice growth and yield can be measured by the parameters of leaf chlorophyll, flowering time, root-shoot ratio, rice yield ha-1 and harvest index.
Based on the description above, the aim of these works here was to study the role of rice husk biochar and rice straw compost in improving soil properties to increase the rice yield. It is necessary to conduct research on the role of rice husk biochar and rice straw compost on the rice yield in the polybag. To find the optimum dose of rice husk biochar and rice straw compost on the growth and yield of rice used, equation of quadratic function is given by Eq.
Based on Table 1, it was evident that the use of rice husk biochar could increase the chlorophyll content of rice leaves. This relationship shows that the application of rice straw compost and rice husk biochar definitely increases the dry weight of the crowns, which is higher than the dry weight of the roots. Effect of interaction between rice husk biochar and rice straw compost on root-canopy ratio.
Rice husk biochar application had a significant effect on flowering age, while rice straw compost treatment had no significant effect on plant flowering age (Table 3). Effect of rice husk biofuel and rice straw compost on flowering age (days). Effect of rice husk biofuel and rice straw compost treatment on rice yield (ton ha-1).
The dose of rice husk biochar of 12.5 ton ha-1 produced higher leaf chlorophyll content of rice. The treatment combination between the dose of rice husk biochar and rice straw compost at 10:10 ton ha-1 produced a better root system (root-leaf ratio) of rice.
