Effect of different fertilizer forms on yield and yield components of chickpea varieties

This research was conducted to determine the effects of different fertilizer forms (control, diammonium phosphate, urea, phosphorus and bacteria) on yield and yield components of some chickpea varieties (Gokce, Diyar 95, Aziziye 94 and Taek-Sagel) in Diyarbakir, Turkey, during 2018 and 2019 growing seasons. In the study, plant height, plant biomass, pod weight, seed yield per plant, number of pods and number of seeds per pod, biological yield, grain yield, 100-seed weight and harvest index were evaluated. The effect of fertilizer treatments on chickpea varieties for all traits were significant, except 100-seed weight, and harvest index. Grain yield ranged from 1274 kg ha-1 to 1479 kg ha-1 among treatments. The control group (1479 kg ha-1), urea (1478 kg ha-1) and diammonium phosphate (1449 kg ha-1) fertilizer treatments had produced more grain yield than bacteria inoculation (1274 kg ha-1) and phosphorus (1332 kg ha-1) treatments.

The Effect of Different Fertilizer and Extraction Method on Secondary Metabolites of Azolla Pinnata

Abstract Azolla pinnata is an aquatic plant that comes from the order of Pteridophyta and family of Azollaceae that can be found floating on the surface of waters and can only grow at non-moving or slow-moving water areas. This research aims to understand the effect of different extraction methods and fertilizers on Azolla pinnata and its secondary metabolites. The fertilizers treatments that were tested were chicken manure and AB. The different extraction methods that were tested were SFE and Soxhlet extraction. In the test, the amount of dry weight of A.pinnata obtained from using AB fertilizer was higher compared to chicken manure. For the extraction, both SFE and Soxhlet extraction produced an almost similar amount of extracts but different amounts of secondary metabolites. The amounts of the secondary metabolites were determined and analyzed using GC-MS. The metabolites identified were theamine, bioxirane, acetic acid, 9 methyl-1-decene, glycerine, dihydroxyacetone, thymine, pyranone, 6-fluoro-2-trifluoromethylbenzoic acid, 2-formyl-4,6 dichlorophenyl ester, and isoglutamine. Based on the result, treatment with AB fertilizer provides higher amounts of secondary metabolites in A.pinnata compared to chicken manure, while for extraction methods, SFE provides higher amounts of secondary metabolites in A.pinnata compared to Soxhlet extraction.

Effects of different fertilizers on growth and productivity of rice (Oryza sativa L.): a review

Rice (Oryza sativa L.) is one of the most important cereal crops in the world. Fertilizer is the major input in rice production. This article reviews on general overview of the effects of different fertilizers on the growth, development and production of rice. Growth and yield traits of rice are affected by nutrients deficiency. Soil testing and use of crop nutrient uptake and removal information are important in determining the actual rates of nutrients. Practice of adequate rate and timing of fertilizer application can increase rice yield. Nitrogen (N), phosphorus (P), and potassium (K) are applied as fertilizers in large quantities to rice fields, and a deficiency of either of the nutrient leads to yield losses. The use of micronutrients such as zinc and Sulphur is one of the important inputs that can increase productivity. Application of NPK fertilizer improves rice plant NPK uptake and also increases the grain yield. The integrating organic and inorganic fertilizers enhances the growth parameters and yields of rice. The balanced use of fertilizers improves crop productivity and soil fertility in a sustainable manner without any environmental damage. This study is a useful tool for scientists, farmers and academics who are interested in rice production, research and development.

Sustainable Fertilizer Strategies for Vaccinium corymbosum x V. angustifolium under Abandoned Peatland Conditions

Revegetating abandoned peatlands plays an important role in reducing the CO2 footprint. One possibility for carbon reduction is cultivating blueberries as calcifuge plants in acidic peat soil. The aim of the experiment was to find out the effect of different fertilizers on half-highbush blueberry cultivar ‘Northblue’ growth and biochemical parameters in peatland conditions. The experiment was carried out in 2011–2015 with four organic and one mineral fertilizer, where three were composted chicken manure- and one maltose-based organic fertilizer. The soil of the experimental area belongs to the soil subgroup Fibri–Dystric Histosol with the peat layer 1.0–1.5 m deep. Organic fertilizer 4–1–2, which contained seaweed but had low phosphorus and potassium content, resulted in high yields in 2011 and 2013, with similar vegetative growth and comparable biochemical parameters as mineral fertilizer 6–14–23. The principal component analysis showed that the experimental year was more important in determining fruit parameters than the fertilizer type. However, our results indicated that the organic fertilizers are alternatives to mineral fertilizer for organic production.

Effects of Different Fertilizers on Rhizosphere Bacterial Communities of Winter Wheat in the North China Plain

The application of bioorganic fertilizer affects rhizosphere microbes and further improves soil fertility in farmlands. However, the effects of different fertilizers on rhizosphere bacterial community diversity and structure of winter wheat remains unclear. In this study, we explored the effects of different fertilization treatments (no fertilizer added, CK; nitrogen fertilizer, NF; bioorganic fertilizer, BOF) on the rhizosphere bacterial community of winter wheat in the North China Plain. Rhizosphere soil treated with BOF had a higher Shannon index than that of CK and NF. The relative abundance of the Proteobacteria treated with BOF was significantly higher than that of NF, while the Acidobacteria and Planctomycetes were significantly lower. The redundancy analysis (RDA) and Mantel test showed that soil bacterial communities were significantly correlated with pH, nitrate, available phosphorus (AP), and available potassium (AK). Our findings indicated that BOF increased bacterial diversity and the relative abundance of copiotrophic bacteria in rhizosphere soil, while NF reduced bacterial diversity and increased the relative abundance of oligotrophic bacteria. The increase in copiotrophic bacteria in the rhizosphere of winter wheat could indicate an increase in soil nutrient availability, which might have positive implications for soil fertility and crop production.

Effects of different fertilizers on the growth and yield of okra (Abelmoschus esculentus L.) in summer season in Chitwan, Nepal

An experiment was conducted in the Horticulture Farm of Agriculture and Forestry University to demonstrate the effects of different fertilizers on the yield and yield parameters of okra (var. Arka Anamika). The experiment was laid out in Randomized Complete Block Design (RCBD) consisting of seven treatments and three replications. The various treatments used in the experiment were goat manure, sesame cake, mustard cake, synthetic fertilizer (NPK), poultry manure, vermicompost and untreated control. The required dose of nitrogen was fulfilled by the fertilizer itself whereas insufficient amount of phosphorous and potassium was fulfilled by addition of single super phosphate and muriate of potash respectively. The fertilizers were applied on the basis of recommendation given by the Nepal Agriculture Research Council (NARC). The effect of poultry manure on number of open flowers and number of fruits at 40 DAS was found superior. The effect of poultry manure on plant height, number of leaves, plant diameter was found superior at 50 DAS. Goat manure produced the superior result on number of open flowers at 50 DAS. Poultry manure on the number of leaves and plant height produced the significant result at 60 DAS. Synthetic fertilizer responded well to number of fruits at 60 DAS. Sesame cake produced the superior results at 70 DAS on number of buds. Poultry manure responded well to all the parameters and produced the yield of 200 qt./ha with the BC ratio of 1.77. This experiment suggests the farmers to use the poultry manure to get the highest economic return. Vermicompost and mustard cake producing the superior and significant yield in this research are not recommended as they have low BC ratio unless effective measures are encouraged to reduce the cost of this fertilizers.

Recovery of Nitrogen and Phosphorus Nutrition from Anaerobic Digestate by Natural Superabsorbent Fiber-Based Adsorbent and Reusing as an Environmentally Friendly Slow-Release Fertilizer for Horticultural Plants

To help minimize the negative impact of chemical fertilizers on the environment, recycle nitrogen and phosphorus nutrients of anaerobic digestate and reduce loss of nutrients via leaching, an eco-friendly slow-release fertilizer was prepared through recovery of nitrogen and phosphorus nutrition from digestate using superabsorbent fibers extracted from soybean curd residue as an adsorbent. The preparation method was proposed, and the fiber composite-based adsorbent was characterized by Fourier transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD), and scanning electron microscope (SEM) techniques. The successful incorporation of N and P into the fiber composite-based adsorbent via adsorption was confirmed by results of these analyses. The prepared fertilizer showed a relatively high N content (3.65 wt%) and a limited P content (0.14 wt%). Also, the swelling capacity as well as water retention capability of the obtained fiber composite-based adsorbent were evaluated. The release behavior of N and P from impregnated fiber composites was examined and was found to be partially in good accordance with the standard of the Committee of European Normalization, showing good slow-release and water-retention properties. Furthermore, in order to assess the fertilizer quality of the prepared materials, the effects of different fertilizers (commercially available fertilizer and prepared slow-release fertilizer) on tomato plant growth and soil microbial communities were investigated. The obtained results demonstrated the potential of fiber composite-based slow-release fertilizer system for recycling N and P nutrition from digestate, improving the effectiveness of fertilizer as well as protecting the environment.

<p class="Body"><strong>Influence of different fertilizer types on life table parameters of citrus red mite, <em>Panonychus citri</em> (Acari: Tetranychidae)</strong><strong> </strong></p>

Citrus red mite, Panonychus citri (McGregor) is an important pest of citrus. In order to assess the effect of different fertilizers applying in citrus on this mite, the biological characteristics on the young citrus trees treated with 3 kinds of fertilizer, organic, chemical and compound (mix of organic and chemical fertilizer) were monitored in a thermostatic room. The immature durations were not affected by different fertilizer treatments. However, the survival rates of the immature stages were significantly higher on compound fertilizer and organic fertilizer than on chemical fertilizer. The fecundity of female mites reared on compound fertilizer citrus was also significantly higher than chemical fertilizer. The pre-oviposition period of females reared on compound fertilizer treated citrus was significantly shorter, and the longevity of males was significantly longer than organic fertilizer. Overall, the mites reared on compound fertilizer treated citrus had the highest net reproduction rate (Ro), index of population trend (I), intrinsic rate of increase (rm), finite rates of increase () and shortest mean generation time (T) comparing with other treatments. The results of nutrient composition determination of citrus leaves treated with three fertilizer treatments showed that the leaves of compound fertilizers contained the highest N, P content and N/K. As P has no positive or direct influence on most phytophagous insects and Acaridae mites in previous studies, the compound fertilizer is beneficial to the optimum population growth of citrus red mite may be closely related to the two indexes, N content and N/K.

Crop yield stability and sustainability in a rice-wheat cropping system based on 34-year field experiment

Abstract Little is known about the effects of different fertilizers and manure use on the yield stability and sustainability of crop in a rice-wheat cropping system. Therefore, a 34-year field experiment (conducted from 1982 to 2015) was used to evaluate the effect of continuous application of inorganic fertilizers and organic manure, supplied at different combinations, on the stability and sustainability of rice and wheat yields. Eight treatments consisted of unfertilized control (CK), inorganic fertilizers (N, NP, NPK) and organic manure (M) either alone or in combination (MN, MNP, MNPK). There was no significant trend of rice grain yield over time for any of the treatments. Wheat yield had an increasing tendency in all the fertilization treatments, including the unfertilized control. Organic manure in combination with chemical fertilizer supported high rice and wheat yields and sustainable yield index (SYI), with decreased coefficient of variance (CV) of rice and wheat yields. The SYI value clearly indicates that rice yield was more sustainable than wheat yield. In conclusion, the combined use of both organic manure and inorganic fertilizer can improve not only crop grain yield but also yield stability and sustainability.

Influence of Kraal Manure, Chicken Manure and Inorganic Fertilizer on Growth, Yield and Post-harvest Quality of Pepper (Capsicum annuum L.) in a Sub-tropical Environment

The excessive unjustified use of some kinds of fertilizers has seen some farmers realizing poor quality fruit that does not appeal to the final consumer, thus negatively affecting the effort of alleviating poverty in the Kingdom of Eswatini. This experiment was carried out at the Horticulture Department Lath House, Faculty of Agriculture, Luyengo Campus of the University of Eswatini to determine the growth, yield and shelf-life of green pepper when fertilized with kraal manure, poultry manure and inorganic fertilizer. The experiment was conducted to find the optimum levels of fertilizers that promotes the growth of pepper and to find the effects of different fertilizers on yield and quality of pepper. The treatments included kraal manure applied at 60 t/ha, [NPK (2:3:2) 37] at 370 kg/ha, chicken manure at 40 t per hectare and the control with no amendment. The results showed that growing pepper using the four treatments significantly affected its growth rate, leaf number, fruit number and its (fruit) shelf life. Pepper grown using inorganic fertilizer had the highest leaf number followed in decreasing order by chicken manure, kraal manure and lastly peppers which did not receive any amendment. There were no significant difference in the growth rate of pepper in the inorganic fertilizer and chicken manure treatments. Similarly, there was no significant difference of pepper grown with chicken manure and chemical fertilizer in the number of days it took the harvested pepper to reach 100% decay stored at room temperature for 21 days. Yet pepper grown with kraal manure was significantly different from the two as it showed 20% decay rate in the same number of days. Although the control had the least decay, the yield was the lowest thus it is not recommended. Kraal manure at 60 t/ha is recommended in the production of pepper with a longer shelf life.

Effects of foliar spraying of l-phenylalanine and application of bio-fertilizers on growth, yield, and essential oil of hyssop [Hyssopus officinalis l. subsp. Angustifolius (Bieb.)

In order to improve growth and yield of medicinal and aromatic plants, the application of natural substances has been increased in recent years. In this study, the effects of different fertilizers under the foliar spray of l -phenylalanine on growth and physiological characteristics and essential oil content of hyssop [ Hyssopus officinalis L. subsp. Angustifolius (Bieb.)], as one important medicinal and aromatic plants, at field condition in southwestern Iran were investigated in a 2-year study (2016 and 2017). Experimental treatments were including arbuscular mycorrhizal fungi , chemical (N.P.K), manure, and vermicompost fertilizers with the control in the main plots and as well as three levels of the foliar application of l -phenylalanine in sub plots. Results indicated that the application of organic/biological fertilizers along with l -phenylalanine spraying have beneficial and effective role in improving the growth characteristics, shoot performance, photosynthetic pigments , and active substances of hyssop. Hence, l -phenylalanine spraying effects on improving arbuscular mycorrhizal fungi symbiosis and the application of manure and vermicompost can be a promising strategy in achieving organic production of medicinal plants such as hyssop. Interaction effects of l -phenylalanine and various fertilizers on hyssop. • The highest dry matter (1.4 Kg m-2) of hyssop was observed from l-phenylalanine spraying under the applied bio-fertilizer. • The maximum essential oil yield (0.4% v/w) from hyssop was obtained from l-phenylalanine spraying along bio-fertilizer. • The foliar spray of l-phenylalanine increased shoot performance, photosynthetic pigments, and active substances of hyssop. • Applied of organic fertilizers and l-phenylalanine had positive effects on growth and quantity and quality yield of hyssop.

Impact of Composting on Growth, Vitamin C and Calcium Content of Capsicum chinense

The nutritional quality of the food has become a serious concern in existing agricultural system as the present world aims to enhance only the food production. A field experiment was carried out to study the effect of different fertilizers on growth, vitamin C and calcium content in yield of Capsicum chinense at Regional Agricultural Research and Development Center, Makandura consisting four treatments as without fertilizer (control/ T1), only compost (T2), compost + inorganic fertilizer (T3) and only inorganic fertilizer (T4) with a randomized complete block design (RCBD) replicating four times. Vitamin C content was measured by Indophenol dye redox titration method and calcium content was analyzed by atomic absorption spectrophotometer. Data was analyzed using analysis of variance. The highest growth was recorded in T3 and no significant differences between treatments in growth parameters at 50% flowering stage.The Vitamin C content was highest in treatment with only compost (T2) and the lowest in treatment compost + inorganic fertilizer (T3). The results indicated that yield from organically managed crops contain significantly higher amount of vitamin C (9.24±2.27 mg/100g, p= 0.0274). The highest calcium content was found in T1 (control) (1.1±0.05 %) and a significant difference (p= 0.0296) was observed between T1 (control) and T3 (calcium=0.75±0.12 %). Compost alone can be used to produce food with high amount of vitamin C. Use of inorganic fertilizer alone or integration of compost with inorganic fertilizer was less effective in producing high quality nutritious foods.

The Effect of Different Fertilizers’ Sources on Micronutrients’ Content and Sugar Quality of Sugar Beet

In order to evaluate the effect of different fertilizers’ sources on micronutrients’ content and sugar quality of sugar beet, three fertilizers’ sources include spent mushroom compost (SMC) (29 t/ha), sheep manure (23 t/ha), chemical fertilizer including zinc sulfate (10 kg/ha), copper sulfate (10 kg/ha), iron sulfate (30 kg/ha), manganese sulfate (15 kg/ha) and no fertilizer (control) were conducted in a randomized complete block design with three replications at Research Farm of Shahrekord University in 2013. The results showed that micronutrients’ content in the root, α-amino-N sucrose percentage and sucrose yield were significantly affected by fertilizer treatments. The highest elements’ content of Fe (90.39 mg/kg), Zn (39.15 mg/kg), and Cu (18.1 mg/kg) in sugar beet root belonged to SMC treatment. Besides, SMC caused less α-amino-N accumulation in sugar beet compared with sheep manure (1.05 MEq/g). Sucrose percentage was higher in SMC treatment than the sheep manure. Likewise, sucrose percentage revealed a significant positive correlation with micronutrients of zinc, copper, and manganese in sugar beet root. Therefore, it could be concluded that using SMC increases micronutrients’ content in the root and at the same time, plays an important role in sugar quality improvement of sugar beet.

Comparison of fertilization prototype on biofloc development and its characteristics in GIFT Tilapia Culture

A study was conducted to evaluate the effect of different fertilizers in GIFT Tilapia culture using biofloc technology. Animals (5±0.23g) were stocked at a density of 30m-3 in 500 litres FRP tanks and spentwash was used as a carbon source to maintain a C:N ratio of 10:1 for 42 days. The experimental group includes fertilization using ammonia sulphate alone (T1) and fertilization using different inorganic fertilizers (T2). No significant differences in FCR, specific growth rate, weight gain and survival of animals were found between the treatments. Proximate composition and fatty acid profile of floc were comparatively rich in T2. Increased solid concentrations with higher Floc volume index and floc sizes were recorded in T2. The rapid floc development along with multiplication of heterotrophic bacteria and decreased vibrio population was observed in T2. The present study confirmed the influence of fertilizers on the physical and nutritional quality of biofloc in GIFT tilapia culture.
