Input factor is one of the determinator the quality and response of the tea plant growth. Inorganic fertilizer input still dominates in Indonesian plantations due to the lack of comprehensive evaluation of organic fertilizers, especially in liquid form. This study aims to determine the effect of inorganic and organic liquid fertilizer applications and the frequency of their application on the growth of tea plants. The experiment was carried out based on a Randomized Block Design (RBD) consisting of six treatment combinations, including tap water application once a week, tap water once every two weeks, 1% urea once a week, 1% urea every two weeks, 1% POC once a week and 1% POC once every two weeks. Experiments were carried out on yielding tea plants with the 3rd year of pruning stage. The parameters observed were shoot production (kg/plot), weight of banji and pekoe (g/100g) and the ratio of banji/pekoe. The results showed that the application of urea foliar fertilizer and liquid organic fertilizer with different application frequencies did not have a significant effect on each observed parameter. Application of 1% liquid organic fertilizer once every two weeks has the potential to increase tea productivity by showing a relatively high production of tea (6,88 kg/plot) compared to other treatments.

The use of inorganic fertilizers has an important role in increasing plant growth and production. But it also causes various problems such as decreasing soil organic matter, soil acidity, soil degradation, nutrient imbalance and increasing environmental pollution. Therefore, it needs to be balanced with the provision of organic fertilizers. A field experiment was conducted to study the effect of application of various doses of inorganic and organic fertilizers on N, P, K nutrient uptake and maize plant growth. The experimental design used was a randomized block design arranged in a factorial manner consisting of two factors. The first factor is the dose of inorganic fertilizer (A): 0, 150 and 300 kg ha-1 phonska and the second factor is organic fertilizer plus (P): 0, 10, 20 tons ha-1. The two factors were combined and each treatment combination was repeated three times. The data obtained were analyzed by analysis of variance at the 5% level of significance. The results showed that there was no interaction between the application of inorganic and organic fertilizers on the growth and nutrient uptake of N, P and K. However, the application of inorganic and organic fertilizers had a significant effect on all tested agronomic traits except for plant height. Nutrient uptake of N, P and K also increased significantly due to the application of inorganic and organic fertilizers. The balance of inorganic and organic fertilizer application increases the availability of nutrients as well as the uptake of N, P, and K nutrients by maize plants.

Organic fertilizer regimens consisting of combinations of composts (yard waste, swine manure, or spent mushroom substrate) and liquid fertilizers (fish- or plant-based) were evaluated against conventional hydroponic fertilizers in two experiments with greenhouse tomatoes grown in peat-based substrate. Crop yield and fruit quality were evaluated and several assays of substrate microbial activity and community profiles (fluorescein diacetate analysis and EcoLog, values, nematode counts) were conducted. Crops grown in 20% to 40% compost (yard waste or yard waste plus swine manure) plus a continuously applied liquid source of organic potassium (K), calcium (Ca), magnesium (Mg), and sulphate (SO4) could not be sustained more than 1 month before nutrient deficiencies became visible. Supplementation with a nitrogen (N)- and phosphorus (P)-containing plant-based liquid fertilizer at the point when plant deficiencies became apparent subsequently produced yields ≈80% that of the hydroponic control. In a second experiment, the proportion of mushroom or yard waste compost was increased to 50% of the mix, and liquid delivery of K, Ca, Mg and SO4 plus either plant-based or fish-based N- and P-containing liquid feeds was started at the date of transplanting. In this case, organic yields equal to that of the hydroponic control (8.5 kg/plant) were observed in some treatments. The most productive organic treatment was the mushroom compost supplemented with a low concentration of the plant-based liquid fertilizer. In general, organic tomatoes had a lower postharvest decay index (better shelf life) than did the hydroponic controls, possibly as an indirect consequence of overall reduced yield in those treatments. High concentrations of both organic liquid feeds resulted in lower yields as a result of treatment-induced fusarium crown and root rot. In contrast to some previous studies, those treatments showing fusarium crown and root rot also had the highest gross microbial activity. Measures of gross microbial activity and numbers of microbivorous nematodes were higher (average of 37% and 6.7 times, respectively) in compost/organic feed treatments than in the hydroponic control. Community physiological profiles of the bacterial populations, on the other hand, did not differ between organic and hydroponic treatments. Nematode populations were significantly correlated with gross microbial activity in the organic treatments.

Liquid organic fertilizer is a technology in fertilizing to facilitate application. This study aims to study the response of three types of caisim plant varieties that are applied liquid organic fertilizer with several levels of concentration. The study was conducted using a Complete Randomized Block Design (RCBD), which was arranged in factorial with three replications. The first factor is three varieties of caisim (V) consisting of three levels, namely: v1 = tosakan variety, v2 = shinta variety, v3 = kumala variety. The second factor is the concentration of organic liquid fertilizer (C) consisting of three levels, namely: c1 = 3 ml / l water, c2 = 6 ml / l, c3 = 9 ml / l. The homogeneity of the research data was tested by Bartlett test and Tuckey tested the data in addictiveness then analyzed with variance and continued with the smallest significant difference test (LSD) at 5% level. The results showed that the use of three types of caisim varieties showed significant differences in the growth and yield of caisim plants as indicated by the plant height, leaf number and shoot-root ratio. The treatment of liquid organic fertilizer concentration showed no significant difference in the growth and yield of caisim plants in all observed variables.

Barley is an important food and beverage crop in the highlands of Ethiopia, although intensive cultivation and suboptimal fertilizer application have caused nutrient depletion and yield decline. With this in view, integrated inorganic and organic fertilizer sources on yield and yield components of barley were studied. Ten treatments involving the sole NP, vermicompost, conventional compost, and farmyard manure based on N equivalency were laid out in a randomized complete block design with three replications in 2015 and 2016 cropping seasons. Significantly higher grain yield and biomass yield of barley were obtained with the application of sole recommended NP and the integrated use of 50 : 50% vermicompost and conventional compost with recommended NP. Mean grain yield of 2567 and 2549 kg·ha−1 barley was obtained from application of 50 :50% conventional compost and vermicompost based on N equivalence with recommended NP fertilizer rate, which markedly reduce the cost of chemical NP fertilizer required for the production of barley. The economic analysis confirmed the profitability of the integrated use of 50 : 50% conventional compost and vermicompost with recommended NP fertilizer for barley production. Therefore, the integrated use of 50 : 50% conventional compost and vermicompost based on N equivalency with recommended NP fertilizer was recommended for sustainable barley production in Chelia district and similar agroecology.

The use of fertilizers is one of the most eff ective methods for ensuring a steady increase in the yield of tea plantations and maintaining it at a high level. The author analyzed agrotechnical requirements for the establishment and maintenance of tea plantations, taking into account the specifi c natural production and physiological characteristics of tea plants. The paper considers the infl uence of agrotechnical methods for the care of tea plantations on their productivity, such as: fertilizing, pruning, and cultivating the soil in the inter-rows. It has been established that both mineral and organic fertilizers greatly infl uencence on the development and productivity of tea plants. The latter type in the form of manure or peat compost, when applied in 4 years one time at a rate of 50 t/ha, gives an excellent eff ect. First, organic fertilizers are used for plantations located on slopes or fl at areas with heavy soils. Doses of nitrogen fertilizers are set depending on the age and yield of the tea plantation. It is noted that plantations with closed rows and trellis trimming do not need deep tillage. On such plantations, it is recommended to carry out winter tillage every 3-4 years with the simultaneous intra-soil application of phosphorus and organic fertilizers. The timing of applying phosphorus fertilizers can be adjusted depending on their content in the soil. It is recommended to leave the trellis pruning material on the plantations as an organic fertilizer for plant nutrition. According to the current agrotechnical requirements, the optimal indicator of soil acidity, at which a tea plant shows maximum viability and can give the highest leaf yield, is PH = 4.0…6.5.
