Organic fresh products are appreciated and are gaining a good reputation regarding human health and environmental concerns. Despite the fact that hydroponics are commonly used in vegetable production, growers are looking for sustainable cultivation systems. Therefore, the objective of this study was to investigate the effect of using an organic-based nutrient solution (NS) derived from fish waste in a hydroponic system on the vegetative growth and production of lettuce compared to a conventional inorganic NS. Plant growth, yield, physiological and nutrient content parameters were determined. The results revealed that the overall growth and fresh biomass of the organic NS grown lettuce were relatively lower than those of the inorganic NS. Stomata density was significantly higher in inorganic grown lettuce compared to the organic one. However, the total chlorophyll, carotene, phenolic compounds, and flavonoid contents, as well as antioxidant activity were significantly higher in lettuce grown in organic NS compared to the inorganic one. Leaf nutrient content at harvest was significantly impacted by the type of used fertilizer. Based on these findings, in hydroponic system, organic liquid fertilizer derived from fish waste (as an alternative NS source) requires further improvements to achieve optimal growth and yield comparable to that of conventional inorganic NS.

The study investigated effect of vermicompost enriched with fish silage on the growth, yield and biochemical constituents of cowpea. The experiment was laid out in a randomised complete block design (RCBD) in three replicates with plot size of 2.0×2.0 m each. The treatments were chemical fertiliser (CF) (100 kg urea + 300 kg single super phosphate ha-1), fish silage enriched vermicompost (VCS) (3.33 t of enriched vermicompost and 300 kg single super phosphate ha-1) and vermicompost (VC) (4.5 t vermicompost + 300 kg single super phosphate ha-1). Data on growth and yield parameters of cowpea were analysed. Chlorophyll and carotenoid content of the leaves were also estimated. Results showed that cowpea performed best with the enriched vermicompost in terms of average yield of fruits per plant (209.27 g), plant height (114.2 cm), total number of branches per plant (13.4), weight per fruit (4.41 g) and number of seeds per fruit (10.5). Cowpea plants given inorganic fertiliser had a better biochemical profile with higher total chlorophyll (37.52 mg g-1) and carotenoid (1.497 mg g-1) content than the organic manure treated plants. Results revealed that enriching vermicompost with fish silage is a potential option for improving the nutrient content of vermicompost, resulting in higher crop production by converting fish waste into a useful byproduct.

Compost has been commonly used as the primary organic matter in organic plant production, especially in vegetable production.  Different sources of compost materials give different medium structures and chemical characteristics. The objectives of this research were: 1) to evaluate the response of growth and yield of chili pepper to a rate of compost and source of animal waste which were used as compost; 2) to determine the optimum rate of fertilizer for the highest growth and yield of chili pepper. The research was carried out from November 2015 until March 2016. Compost material treatments consisted of cow dung, empty palm oil bunches, and mixed of vegetable residue and weeds. The compost rate treatments consisted of 0 ton ha-1, 10 ton ha-1, 20 ton ha-1, and 30 ton ha-1. No interaction between the two treatments was found to influence plant growth and yield variables.   The type of compost materials affected plant height of 5, 6, and7 weeks after transplanting.  Cow dung as a source of compost showed the best effect in increasing chili plant height.  Plant height, the number of plant dichotomous, and plant canopy responded linearly  to the increase of the compost rate. The usage of compost at 20 ton ha-1 and 30 ha-1 resulted in higher fruit length, the number of fruit, and fruit weight per plant.   Keywords: chili pepper, compost, organic, growth, yield

The experiment was conducted at Regional Agricultural Research Station (RARS), Jamalpur, Bangladesh during the period of 2019-2020 and 2020-2021 to investigate the effect of vermiwash on growth, yield and quality of brinjal and to find out suitable foliar dose of vermiwash for optimizing the yield of brinjal. There were five treatments comprising T1= Chemical fertilizer (CF) + foliar spray of distilled water (control), T2 = CF + foliar spray of 10% vermiwash, T3 = CF + foliar spray of 20% vermiwash, T4 = CF + foliar spray of 30% vermiwash and T5= CF + foliar spray of 40% vermiwash. Results revealed that, vermiwash treated brinjal plants showed better growth and yield parameters than the control plants. The highest average brinjal fruit yield (29.99 t ha-1) was found in T3 treatment i.e., foliar spray of 20% concentration of vermiwash and the lowest (26.35 t ha-1) came from control. On the other hand, nutritional quality (moisture content, TSS, β carotene and nutrient content) were seen to be higher in vermiwash treated treatment compared to control treatment. The study suggests that, 20% concentration of vermiwash could be used as effective foliar spray for eco-friendly and higher yield of brinjal.

The application of a closed hydroponic system for rose poses some horticultural problems. The nutrient uptake by the plants changes constantly depending upon environmental conditions and growing stages, which results in the imbalanced composition of the drained solution and aggravates root environmental conditions. This research was aimed to observe the effect of mineral nutrient control method on the nutrient solution management in a closed hydroponic system. Single-node cutting rose `Versillia' was grown in aeroponics and DFT system and was irrigated with the nutrient solution of the Univ. of Seoul (NO3 -N 8.8, NH4 -N 0.67, P 2.0, K 4.8, Ca 4.0, and Mg 2.0 me·L-1). Recirculated nutrient solution was managed by five different control method: macro- and micro-element control in aeroponic system (M&M); macroelement control in aeroponic system (M); nutrient solution supplement in aeroponic system (S); electrical conductivity (EC) control in aeroponic system (EC-A); EC control in deep flow technique system (EC-D). In the EC control method, the concentration of NO3 -N exceeds optimal range whereas P and Mg decreased at the later stage of plant growth. The overall mineral nutrient content increased with S. On the other hand, the nutrient content of root environment was maintained optimally with M&M and M.

Nutrient solution and its nutritional compositions may have the effect on growth and fruit quality attributes of cherry tomato. To avoid the build-up of toxins, mineral deficiencies, nutrition abnormalities, or the spread of disease, producers should use optimum level of nutrient solution. Therefore, the present experiment was conducted to identify a suitable strength of nutrient solution for cherry tomato in hydroponic system. Treatment considered six levels of nutrient solution [viz., S1: ½ strength Rahman and Inden (2012), S2: ¾ strength Rahman and Inden (2012), S3: Full strength Rahman and Inden (2012), S4: ½ strength Hoagland and Arnon No. 2(1940), S5: ¾ strength Hoagland and Arnon No. 2 (1940) and S6: Full strength Hoagland and Arnon No. 2 (1940)] and two varieties [viz., V1: Local market cherry tomato (red), V2: Irelands cherry tomato (yellow)]. Growth and yield contributing characters, quality parameters, physiological traits and biochemical composition were analyzed.  The maximum plant height, number of leaves per plant, first flowering, number of flowers per cluster, number of fruit per cluster, number of cluster per plant, average individual fruit weight and average cluster weight per plant were found in S3. Meanwhile, V2 performed better in respect of plant height, number of leaves per plant, first flowering, number of flowers per cluster, number of fruit per cluster, number of cluster per plant, average individual fruit weight and average cluster weight per plant. Therefore, cherry tomato cv. V2 can be cultured in hydroponic system with applying S3 (Full strength Rahman and Inden nutrient solution).

Okra (Abelmoschus esculantus) L. Moench), is an important vegetable that grows in the tropical and sub-tropical parts of the world. Okra plants contain very high nutritional value (at 100 g of young okra fruit containing 35 g of calories, 89.6 g of water, 6.4 g of carbohydrates, 1.9 g of protein, 0.4 g of fat, 1.2 g of fiber, 0 , 7 g of minerals). In Indonesia, okra plants have not been widely cultivated and the cultivation method has not used the right technology, so it is necessary to examine the proper cultivation methods of Okra. This study aims to determine the EC value of the most optimal nutrient solution and the effect of the type of planting media that is best on the growth and yield of okra plants. The research was carried out in plastic houses located in Pondok, Karangbendo, Banguntapan, Bantul, Yogyakarta in May to August 2018. Experiments using polybag with a Complete Randomized Block Design (RAKL) Split Plot two factors were repeated 3 times. The first factor as the main plot is the EC value of nutrient solution (C1: EC value 1.5 mS / cm, C2: EC value 2 mS / cm, C3: EC value 2.5 mS / cm) and the second factor as sub plot is type planting media (M1: Husk charcoal, M2: Sand Malang, M3: Husk charcoal + Cocopeat (1:1). The results showed that there was no interaction between the treatment of giving various EC values of nutrient solution and type of planting media. The treatment of various EC values of nutrient solution and type of planting media significantly affected the parameters of plant height growth, leaf area, root volume, flowering age, stem diameter, parameters of total fruit yield per plant, fresh weight per fruit, total fruit weight per plant, fruit weight per Ha. The treatment of giving EC values of 2.0 mS / cm showed suitable results for the growth and yield of okra plants. The treatment of the type of husk charcoal growing media showed suitable results for the growth and yield of okra plants.Keywords: Okra Plant, Substrate Hydroponic, Planting Media, Solution EC Value

Agricultural utilization of bioslurry plays a critical role in soil conditioning and hence crop production. It also reduces greenhouse gas emissions thus mitigating climate change. Although the effect of bioslurry on growth and yields is well researched, that of different biodigester types is under-researched. Therefore, a study was carried out in Waruhiu Agricultural Training Centre, Githunguri sub-county, Kiambu county in Kenya, to investigate the effect of bioslurry from flexi and dome biodigesters on soil chemical properties, maize growth, yield and grain quality. Treatments were laid out in a Randomized Complete Block Design (RCBD) and replicated three times. The treatments were bioslurry from both Fixed Dome and Flexi biodigesters, applied separately at a rate of 400mls per hill as basal and top dress fertilizer. Planting was done during the 2019 short and 2020 long rains, using Duma 43 maize variety. The agronomic (germination percentage, number of leaves, leaf width, leaf length, plant height) and productivity data (stalk, stovers, grain yields and grain quality) were subjected to analysis of variance (ANOVA) through Proc general linear model (GLM) procedures. Mean separation was done using least square means (LS-Means). Results showed an increase in soil pH, total N and OC, exchangeable P, K, Mn and Na in both biodigester types. Total N and OC were higher in Dome treated soils by 38.89% and 37.00%, while in Flexi, it was 16.67% and 16.00% respectively. Exchangeable P and K was higher in Flexi treated soils with a 38.57% and 50.00% increase while in Dome it 37.86% and 47.22% respectively. Magnesium and Zn decreased after treatment by 34.30% and 22.59% in Dome while Flexi had 33.23% and 31.79% increase. Exchangeable Fe and acidity decreased in Dome but increased in Flexi treated soils. No statistical differences were observed on growth and yield parameters but Dome registered higher grain yields by 9.4% and 6.3% for short and long rains respectively. Flexi treated soils registered higher values in most grain nutrient content such as K, Fe, Cu, Mn and Zn in short rains and P, Ca, Fe, Cu, Mn and Zn in the long rains. Bioslurry from both biodigester types variably increased the evaluated soil chemical properties but decreased Mg and Zn. Despite the numerical differences noted between bioslurry from both biodigester types on maize growth and yield, there was no significant difference (p≤.05). However, Dome bioslurry increased N, OC and maize grain yield more while exchangeable P and K and most of the grain nutrient content were higher in Flexi treated soils. Therefore, bioslurry from either biodigester type can be used in enhancing soil conditions, growth, yield and quality of maize. However, a long-term experiment is required validate the findings.
