This study aims to determine the effect of inorganic fertilizer, organic fertilizer, and the combination of both on the growth of king grass (Pennisetum purpurephoides). The research method was a completely random design with 4 treatments and 5 replications. The research treatments consisted of A (without fertilizer), B (100% inorganic fertilizer), C (100% organic fertilizer), and D (50% inorganic and 50% organic fertilizer). The result of the study shows that inorganic, organic, and its fertilizer combination treatment has a non-significant effect on the height of the plant, the length and width of the leaf, and the length of its segments, while inorganic and organic fertilizer treatment has a significant effect on the stem diameter. The conclusion is that the use of 100 % organic fertilizer has better results for the vegetative growth of king grass (Pennisetum purpurephoides) compared to the use of inorganic fertilizer and its combination.

The productivity of forage depends on the availability of nutrients in the soil where it is grown, so fertilization to replace harvested produce is absolutely necessary. This study aims to study the response of gamal and indigofera forage on application of inorganic and organic fertilizers. Research using a completely randomized design factorial pattern of two factors, the first factor is the type of plant (G = Gamal; I = Indigofera) and the second factor is the type of fertilizer (T = without Fertilizer; A = Inorganic fertilizer NPK; K = commercial organic fertilizer; O = conventional organic fertilizer; B = bioorganic fertilizer), repeated 4 times so that it consists of 40 experimental units. The variables observed were plant height, number of leaves, stem diameter, leaf dry weight, stem dry weight, total dry weight of leaves, ratio of dry weight of leaves/stems and leaf area per pot. The results showed that there was no interaction between plant species and types of fertilizer in influencing the response of gamal and indigofera plants. Plant species have a significant effect on stem diameter, while fertilizer types have a significant effect on plant height, leaf dry weight, total dry weight of leaves and leaf area per pot. Based on the results of the study it can be concluded that the response of gamal plants is similar to indigofera, all types of fertilizers can improve the response of plants and organic fertilizers produce the same crop response with inorganic fertilizers.

[CABBAGE (Brassica olacea var. capitata) GROWTH AND YIELD AFFECTED BY COMBINATION OF ORGANIC AND INORGANIC FERTILIZER APPLICATIONS]. The use of organic fertilizer increasingly sought by farmers due to the increase in demand for organic products by consumers and also awareness of the sustainability of the land. The use of organic fertilizers in the cultivation alone could improve the soil quality but needs to be balanced with inorganic fertilizers to meet the nutrient adequacy. This study aims to examine the effect of organic and inorganic fertilizers combination on the growth and cabbage yield, and also to determine the most efficient dosage combination of organic and inorganic fertilizers. This research was conducted at the IPB Pasir Sarongge Experimental Station, Cianjur, West Java from November 2020 to February 2021. The study was compiled using RCBD with 4 replications and 7 treatments. The results showed the combination of 0.75 doses of inorganic fertilizer (150 kg/ha of urea, 75 kg/ha SP36, and 75 kg/ha KCl) and 3 tons/ha of organic fertilizer could increase 14.87 to 15.44% plant height and the number of leaves at 12.82 -15.11% compared to the same dose of inorganic fertilizer treatment alone. The combination of 1 dose (200 kg/ha of urea, 100 kg/ha SP36, and 100 kg/ha KCl) inorganic fertilizer application and 2 tonnes/ha of organic fertilizer could increase 50,60% yield/plot and yield/ha cabbage than 1 dose of inorganic fertilizer treatment..

Fertilizer application is essential in the improvement of soil quality and crop yield; it was therefore necessary to investigate the effects of integrated application of inorganic and organic base fertilizer on the soil chemical and physical properties. This experiment was conducted at the Ambrose Alli University Teaching and Research Farm, Ekpoma, Nigeria. The experiment was laid out in a Randomized Complete Block Design (RCBD) with seven treatments, replicated three times; the treatments were; control (zero application), Indorama granular urea (GU), prilled urea (PU), full dose of P&K+75% Indorama granular urea (GUPK), full dose of P&K+75% prilled urea (PUPK), full dose of P&K+75% Indorama granular urea + 25% FYM (GUP&K+FYM), and full dose of P&K+75% prilled urea + 25% FYM (PUP&K+FYM). The rice variety cultivated was FARO 59. The initial results of the soil analyses showed that the soil was low in nutrient below critical values, the combine application of organic and inorganic fertilizer significantly (p<0.05) improved soil nutrient status compared to the other treatments. The combined application of inorganic and organic fertilizer increased soil pH value from 5.64 in control to 6.92. There was a significant (p< 0.05) improvement of the macro and micronutrient from the integrated application of inorganic and organic based fertilizers compared to other treatments. The application of GUP&K+FYM and PUP&K+FYM significant (p< 0.05) improved the Aggregate stability of the soil. The integrated applications of organic and inorganic fertilizer (GUP&K+FYM and PUP&K+FYM) will significantly (p< 0.05) improve the chemical and physical properties of soil.

AbstractIn the image forming methods, copper chloride crystallization (CCCryst), capillary dynamolysis (CapDyn), and circular chromatography (CChrom), characteristic patterns emerge in response to different food extracts. These patterns reflect the resistance to decomposition as an aspect of resilience and are therefore used in product quality assessment complementary to chemical analyses. In the presented study, rocket lettuce from a field trial with different radiation intensities, nitrogen supply, biodynamic, organic and mineral fertilization, and with or without horn silica application was investigated with all three image forming methods. The main objective was to compare two different evaluation approaches, differing in the type of image forming method leading the evaluation, the amount of factors analyzed, and the deployed perceptual strategy: Firstly, image evaluation of samples from all four experimental factors simultaneously by two individual evaluators was based mainly on analyzing structural features in CapDyn (analytical perception). Secondly, a panel of eight evaluators applied a Gestalt evaluation imbued with a kinesthetic engagement of CCCryst patterns from either fertilization treatments or horn silica treatments, followed by a confirmatory analysis of individual structural features. With the analytical approach, samples from different radiation intensities and N supply levels were identified correctly in two out of two sample sets with groups of five samples per treatment each (Cohen’s kappa, p = 0.0079), and the two organic fertilizer treatments were differentiated from the mineral fertilizer treatment in eight out of eight sample sets with groups of three manure and two minerally fertilized samples each (Cohen’s kappa, p = 0.0048). With the panel approach based on Gestalt evaluation, biodynamic fertilization was differentiated from organic and mineral fertilization in two out of two exams with 16 comparisons each (Friedman test, p < 0.001), and samples with horn silica application were successfully identified in two out of two exams with 32 comparisons each (Friedman test, p < 0.001). Further research will show which properties of the food decisive for resistance to decomposition are reflected by analytical and Gestalt criteria, respectively, in CCCryst and CapDyn images.

Two species of mint Mentha piperitha (peppermint) and M. arvensis (Japanese mint) are widely cultivated in Iran, but their response to fertilizer regime has not been evaluated so far. A field experiment was conducted to investigate the effects of different organic and chemical fertilizer treatments [Control, 100% urea (95 kg N ha−1), 75% urea (71.25 kg N ha-1) + 25% vermicompost (3.3 t ha-1), 50% urea (47.5 kg N ha-1) + 50% vermicompost (6.75 t ha-1), 25% urea (23.75 kg N ha-1) + 75% vermicompost (10.1 t ha-1) and 100% vermicompost (13.5 ton ha-1)] on essential oil contents, yield and yield components of the two species of mint. Peppermint provided grater plant height, number of internodes, number of leaf and oil percentage compared with the Japanese mint under study. The results indicated that, irrespective of the mint species, plants treated with combined chemical and organic fertilizer presented taller plants, higher oil contents and oil yield compared with solo chemical or organic fertilizers. Oil percentage and essential oil yield of mint increased significantly under the treatment with 25% urea (23.75 kg N ha−1) + 75% vermicompost (10.1 t ha-1). Plant height and number of leaf increased along the replacement of organic fertilizer with chemical fertilizers. The results showed that there was a positive and significant correlation with leaf number and essential oil yield. Application of vermicompost in combination with chemical fertilizer increased plant height, oil percentage and essential oil in both species, suggesting that organic and chemical fertilizer combination improves performance and environmental sustainability.
