The impact of water hyacinth manure on growth attributes and yields in Coriandrum

Crude oil is a complex hydrogen whose introduction into the may be hazardous to aquatic and human life, and consequently a threat to natural resources. The severity of the impact of crude oil depends on a variety of factors, including characteristics of the oil itself, natural conditions, such as water temperature and weather, and the sensitivities of receiving or biota. Consequently, various types of biological resources such as mangrove seedlings have different sensitivities to oil spills. The long term persistence of oil in the environment may cause defoliation and possibly death. Recruitment of seedlings into the oiled area may also be affected. This study is designed to evaluate the acute and chronic effects of crude oil (Bonny Light) on the growth performance of mangrove seedlings in a laboratory condition; monitoring critical plant growth attributes such as stem height and diameter, leaf length, width and numbers of leaves (leaf production), senescence and seedlings survival, for sixteen weeks. The study revealed that the mangrove seedlings responded differently in growth attributes with varying treatment. Evidence of crude oil effects were remarkably demonstrated between control and acute (Wilcoxon sign –rank t-test (1.0) > P (0.29)0.05 and chronic (Wilcoxon sign – rank, t-test (1.0) > p (0.47)0.05. The mangrove critical growth responses by mangrove seedlings as a result of the treatments were further explained by the cluster and correspondence analyses.

Central Composite

The production cost of β-glucosidase and endoglucanase could be reduced by using water hyacinth, an aquatic weed, as the sole carbon source and using cost-efficient fermentation strategies like solid-state fermentation (SSF). In the present study, the effect of different production conditions on the yield of β-glucosidase and endoglucanase by Rhizopus oryzae MTCC 9642 from water hyacinth was investigated systematically using response surface methodology. A Central composite experimental design was applied to optimize the impact of three variables, namely, substrate concentration, pH, and temperature, on enzyme production. The optimal level of each parameter for maximum enzyme production by the fungus was determined. Highest activity of endoglucanase of 495 U/mL was achieved at a substrate concentration of 1.23%, pH 7.29, and temperature 29.93°C whereas maximum β-glucosidase activity of 137.32 U/ml was achieved at a substrate concentration of 1.25%, pH 6.66, and temperature 32.09°C. There was a direct correlation between the levels of enzymatic activities and the substrate concentration of water hyacinth as carbon source.

The Impact

Organic manure from different sources could be an effective substitute of chemical fertilizers. Therefore, a field experiment was conducted to study the impact of various sources of organic manures viz., sole application of composted pressmud, vermicompost, sewage sludge and farmyard manure and its combination with various levels of inorganic fertilizers on growth attributes, biomass yield, yield attributes, secondary nutrient uptake and its available status and quality parameters of bhendi (A. esculentus (L.) Moench). The results indicated that application of pressmud @ 5 t ha-1 with 50 per cent recommended dose of fertilizer had recorded the highest calcium and magnesium uptake of 30.9 and 15.4 kg ha-1 respectively and biomass yield of 2233.2 kg ha-1, In comparison to control, the increases in biomass yield and calcium and magnesium uptake were 20 and 51 and 136% higher under the same set of treatment combinations . The results revealed that treatment received with pressmud application @ 5 t ha-1 along with 50 per cent recommended dose of fertilizers registered highest available calcium and magnesium content of 0.14 and 0.28% respectively. In addition to that, there was an improvement in growth parameters such as plant height and number of branches plant-1 at all the growth stages of crop and also quality attributes viz., crude fibre (10.2%) and mucilage content (1.56%) were recorded significantly highest by same treatment compared to control (15.0 and 1.2% respectively). Among the organics, pressmud based inorganic fertilizers application was suitable for higher biomass yield, improvement in quality parameters and also maintaining the fertility status of the secondary nutrients in soil.

This examination assesses the impact of blending proportion (1, 1.5, 2 and 2.5) and chemical pre-treatment on the anaerobic co-processing of banana strips and water hyacinth. Two plans of bio-engineered methane potential (BMP) tests were performed all the while. Banana strips was blended with untreated water hyacinth in set I, and water hyacinth be pretreated before co-absorption in set II. Intent measure of bovine compost and dairy animals pee was added to every reactor as an inoculum. The anaerobic group test revealed that set II, where pre-treated banana strips and water hyacinth was co-handled, demonstrated high biogas creation and favoured nature of biogas over set I. Blending proportion 1.5 and 2 were outlined to be the ideal blending proportion for set I and II individually. Both the sets represented high biogas age than mono-processing of the substrates. In this way, anaerobic co-absorption of banana strips and water hyacinth depict a synergic activity via adjusting the general procedure. The purpose of this peculiar analysis was to scrutinize the repercussion of different mixing ratios and chemical pre-treatment on the anaerobic co-digestion process

The Impact

Ammonium (NH4+) to nitrate (NO3-) ratio and growth media significantly alter plant development and NO3- accumulation in lettuce. Nitrate accumulation is regarded harmful for environment and human health. The quality of lettuce is assessed by NO3-concentration, size, and weight. This study determined the impact of five different growth media (cocopeat, peat, bark, perlite and rockwool) and four different NH4+:NO3- ratios (0:100, 20:80, 40:60 and 60:40) on NO3- accumulation in lettuce, yield, and several growth attributes. The experimentation was conducted according to open feeding system of soilless agriculture. The ‘Cosmos’ variety of lettuce was used as experimental material in the study. Growth mediums and NH4+:NO3- ratios significantly altered NO3- accumulation, head, leaf, stem and root traits. The results revealed that instead of growing lettuce with NO3- only in peat and rockwool, addition of NH4+ (20:80 of NH4+:NO3-) into nutrient solution increased head weight. While head weight increased in perlite medium with the addition of NH4+, it decreased in cocopeat and bark media. It is concluded that growth media and NH4+:NO3- ratios pose significant impacts on NO3- accumulation in leaf and that the increase in NH4+ ratio decreased NO3- accumulation in all growing media. Therefore, it is recommended that NH4+ should be added in the nutrient solution to decrease NO3- accumulation, which will ultimately improve yield and quality of lettuce.

The Impact

The impact of nutrient sources cannot be over emphasised in plant growth. Seedlings of Annona muricata were subjected to organic fertilizers, inorganic fertilizers and fertilizer-free treatmentsin this study. The organic fertilizers comprises of cow dung, poultry manure and water hyacinth, while NPK fertilizer was used as the inorganic manure and Top soil without fertilizer application was used as the control. The organic fertilizers were singly used and mixed at the rate of 100kg/ha and 200kg/ha while the inorganic fertilizer was used at the rate 100kg/ha and 200kg/ha. The parameters taken were plant height, stem girth, leaf area and leaf production. Results obtained showed that poultry manure produced the tallest plants (23.50cm) at 3months after transplanting though this was not significantly different from those of cow dung manure (23.00cm). NPK fertilizer produced the plant with highest leaf area (32.75cm) and stem girth (2.25cm) at 3 months after transplanting and was not significantly different from the organic fertilizers (Poultry manure 200g/ha, Cow dung 200g/ha, Water hyacinth 100g/ha and 200g/ha). NPK fertilizer also produced the highest number of leaves at the end of the three month assessment (31.00cm). All the growth parameters observed showed that the control experiment gave the least performance. The results obtained tend to suggest that the use of NPK fertilizer should be recommended for growing Annona muricata and improvement of the soil nutrients level.
