The objectives of this study are twofold; firstly, it is intended to determine the soil nutrient contents (e.g., nitrogen, phosphor, potassium, manganese, and magnesium) after the provision of Chromolaena odorata organic fertilizer. Secondly, the study is aimed at examining the growth of maize crops after the provision of the same fertilizer. It employed randomized design group consisting of three phases of treatment (i.e., control, fertilizer provision, and provision of Bokashi with Chromolaena odorata) and four-times of the repeating process. Furthermore, the variable consists of the contents of soil nutrient  before applying the treatment, vegetative growth (i.e., stem height, stem diameter, leaf size, and dry weight of root, stem, and leaf), and generative growth (i.e., weight of unhusked cob, weight of husked cob, number of seeds per cob, width of cob, and weight of 100 seeds).  The data were analyzed by using analysis of variance (ANOVA) and it further examined by employing Least Significance Difference test at 5% level. The results reveal that the provision of Bokashi fertilizer (with Chromolaena odorata as the material) positively impacts the growth of maize crops rather than the provision of green manure and control fertilizer. Keywords: Generative Growth, Organic Fertilizer, Vegetative Growth

The organic fertilizers such as urban wet-waste compost and vermicompost can improve the physicochemical properties of soil and have a favourite effect on plants growth due to the high nutrient content, high water holding capacity, plant growth regulators, and beneficial microorganisms. In this regard, this study was conducted to evaluate the organic fertilizer mixture on the physiological and morphological indices of tomato seedlings under greenhouse conditions. The experiment was done as factorial in a completely randomized design with 3 replications. The evaluated factors included the vermicompost fertilizer (0, 10, 20, 30 wt %), and the urban wet-waste compost (0, 10, 20, 30 wt %). In evaluation of the simple-effects of vermicompost and urban wet-waste compost the results showed that the 30 wt % level compared to the control sample increased the leaf area (+12.28% and +9.33%). It also increased the number of leaves (+17.5% and +22.9%), dry weight of root (+17.3% and +16.9%), chlorophyll-b content (+4.9% and +12.3 %), carotenoids (+2.9% and +7.9 %), and the total chlorophyll content (+23.7% and +13.8%). Results of evaluating the treatments showed that the vermicompost and urban wet-waste compost mixture in 30 wt % level (V4C4) caused significant increase in the plant height, leaf dry weight, root length, relative water content, cell membrane stability coefficient, efficiency of photochemical performance of PSII and the chlorophyll-a content (compared to other treatments especially low levels of organic fertilizer consumption). According to the final results of this study, using the vermicompost and urban wet waste compost mixture in 30 wt % level is recommended to improve the morphological and physiological traits of tomato in greenhouse conditions.

The Ministry of Agriculture through the Agricultural Quarantine Agency (2019) stated that Robusta coffee has contributed 41% of the country's foreign exchange, with an average export frequency of 102 times per month, and will continue to increase. In connection with the growth in export volume of robusta coffee, coffee farmers need additional substances for the soil in the form of nutrients to be able to meet the soil nutrient needs for coffee from planting to harvest. Organic fertilizer in liquid form is one type of fertilizer that can be an option, in addition to facilitating nutrient absorption. This study aims to determine the response of various liquid organic fertilizers at certain concentrations to the vegetative growth of robusta coffee. The content of C-organic and total Nitogen in the soil which has been given the addition of gamal liquid organic fertilizer and tofu wastewater with the addition of citronella can provide a very significant difference in the vegetative growth of robusta coffee plants at the age of 60 HSP at plant height, and 90 HSP in diameter. stem and number of leaves (strands). Based on the results of laboratory tests carried out, it was also known that the macro and micro nutrient content in the soil with the addition of poc of tofu wastewater which was given citronella had a good content compared to the control and soil conditions with the addition of gamal liquid organic fertilizer.
