Penggunaan Slurry sebagai Pupuk Organik terhadap Kualitas dan Fermentabilitas Rumput Setaria (Setaria splendida Stapf) di Rumen

Biogas slurry is an organic product derived from livestock manure and produced through an aerobic fermentation process that can be used to improve soil fertility, forage production, and quality. This study aimed to investigate the effect of slurry organic fertilizer on crude protein content, crude fiber, and total fermentation gas production in the rumen in vitro . The study was conducted in a completely randomized design (CRD), consisting of five treatments of slurry levels as organic fertilizer and four replications consisting of two experimental units. The treatments consisted of S0 = without slurry, S1 = slurry 20 g/polybag, S2 = slurry 25 g/polybag, S3 = slurry 30 g/polybag, and S4 = slurry 35 g/polybag. The variables measured in this study were crude protein content, crude fiber, and total fermentation gas production. The data obtained were analyzed using a variance analysis (ANOVA). Duncan’s test was used to determine the effect of different levels of slurry on the measured parameters. The results showed that the use of slurry as an organic fertiliser increases crude protein content by an average of 16.06%, increases crude protein production from 1.47 g/poly bag to 96.38 g/poly bag and improves fermentability in the rumen by an average of 8.08% of setaria grass (Setaria splendida Stapf). The use of slurry at the level of 35 g/poly bag is recommended for the cultivation of setaria grass (Setaria splendida Stapf).

Growth of Indigofera zolingeriana with differences in source of cuttings and planting media

This study investigates the effect of different cutting types and planting media on the growth of Indigofera zollingeriana, a valuable forage crop. The research used a factorial randomized block design (2 x 2) with 40 experimental units. The treatments included two cutting sources—stem cuttings (A1) and shoot cuttings (A2)—and two planting media—natural soil (B1) and natural soil supplemented with liquid organic fertilizer from rabbit urine (B2). Growth parameters such as the number of leaves, plant height, and stem diameter were measured. The results indicate that cutting type significantly affects leaf production, with shoot cuttings (A2) producing a higher number of leaves than stem cuttings (A1) (P<0.05). However, the planting media and its interaction with the cutting type had no significant impact on plant height and stem diameter (P>0.05). These findings suggest that using shoot cuttings could enhance the propagation and growth of Indigofera zollingeriana for sustainable forage production. Further studies are recommended to explore the long-term effects of organic fertilizer on biomass yield.

Long-term manure and/or straw substitution mediates phosphorus species and the phosphorus-solubilizing microorganism community in soil aggregation

The partially substitution of chemical fertilizers with organic materials can improve soil phosphorus (P) availability; however, the response of aggregate-associated P species and the microbial community remains unclear. We investigated P speciation transformation and the related microbial community of aggregates in a 10-year field trial containing chemical fertilizer (CC), 50 % chemical N replaced by pig manure, corn straw, and manure combined with straw. Compared to CC, the organic substitute pattern increased soil aggregate stability indices, which were positively correlated with labile and moderately labile P. The organic substitution pattern improved labile and moderately labile P in > 2 mm large macroaggregates (LM) and 0.25–2 mm macroaggregates (MA), and decreased labile P in 0.053–0.25 mm microaggregates (MI) and < 0.053 mm silt + clay (SC). CaHPO4 and MgHPO4 of labile P were the primary components in MA, while Ca(H2PO4)2 was the primary component in MI. Straw addition enhanced the relative abundance of P-solubilizing microorganisms, primarily Bacillus, in different aggregates. The labile P content was higher, and the microbial network displayed higher complexity and connectivity in MI than in aggregates of other sizes. pH was the most critical factor influencing the distribution of P species in the LM. Organic carbon and aggregate stability index were the primary factors in MA, whereas phosphatase activity was the primary factor in MI and SC. Overall, the organic substitution pattern improved aggregate stability and labile P content in LM and MA and reduced labile P in MI and SC, thereby promoting P retention. These insights advance our understanding the effects of organic fertilization on P transformation in soil aggregates, with implications for developing eco-friendly P management strategies.

Effect of Organic and Inorganic Fertilizers on Growth, Yield and Quality of Radish (Raphanus sativus L.) cv. Pusa Himani

In this report, we compared the integrated effect of FYM, vermicompost, poultry manure with inorganic fertilizers incorporated with PSB for yield in radish cv. Pusa Himani in response of morphological, yield as well as quality attributes. As per data analysis T6 [NPK (75%) + vermicompost (25% of N) + PSB] significantly enhanced the highest plant height, leaf length, number of leaves per plant, fresh weight of shoot and dry weight of shoot at 20 DAS, 40 DAS and at harvest, respectively. Similarly, at harvest maximum root length, maximum root diameter, maximum average weight of root, maximum yield per hectare, minimum days to harvest and quality parameters i.e. T.S.S., ascorbic acid, chlorophyll content of leaves, net return and B-C ratio in comparison to all concentration with all integrated nutrient combination. So, we may conclude that [NPK (75%) + vermicompost (25% of N) + PSB] increase yield by stimulating source activity as well improves utilization of PGR (plant growth regulators).

Comparison of Pb adsorption and transformation behavior induced by chicken manure and its DOM in contaminated soil

Organic fertilizer derived from animal manure can significantly improve soil fertility. However, limited research has investigated the capacity of exogenous organic fertilizer dissolved organic matter (DOM) to migration and transform heavy metals. In this study, the effect of chicken manure organic fertilizers with different maturity and their DOM on changes of Pb bioactivity was evaluated and the role of soil environmental factors driving the changes was determined through soil incubation, adsorption and leaching experiments. The FTIR results indicated that DOM derived from farmhouse chicken manure organic fertilizer (FCMD) contained more protein-like compounds and low maturity, while DOM from commercial chicken manure organic fertilizer (CCMD) contained more humic/fulvic acid and high maturity. FCMD and CCMD reduced the content of RES-Pb by 16.3–27.52 % and 6.66–13.98 %, respectively. And the effects of organic fertilizers and their DOM on Pb migration and activation follow the order of FCMD> CCMD> CK> commercial chicken manure organic fertilizer (CCM)> farmhouse chicken manure organic fertilizer (FCM). FTIR analysis showed that FCMD was primarily composed of aromatic unsaturated functional groups, and its adsorption capacity for Pb2+ was significantly lower than that of FCM. In addition, the application of FCMD significantly altered the physicochemical properties of soil and promoted the migration and leaching of Pb. FCMD not only causes the soil Pb2+ to be released into the effluent but also activates Pb from the stable form into the active form. In summary, animal manure with lower maturity has a risk to activate heavy metals and should be applied with cautions.

Effect Of Animal And Plant Organic Fertilizers On Growth And Yield Of Rice In Tana Delta, Kenya

Rice is the 3rd most consumed cereal in Kenya while production is merely 20% of the demand making the country a net importer of the commodity. With increased global concern on healthy foods, producing more rice to contribute to achieving food secure nation while conforming to environmental sustainability remains a subject of concern in the country. In this case, good agricultural practices are needed to strike the balance. This study was carried out during rice growing season (February – June, 2024) to investigate the effect of basal organic fertilizers; Rich Farm (RF), Han Daebak (BK) and Han Yoobak (MK) on growth and yield of AT054 and Komboka rice varieties in Tana Delta Irrigation Project-Rice (TDIP-R) Scheme during the trial Phase undertaken by Agri All Africa (AAA) in preparation for a Public Private Partnership (PPP) project programme. The study was conducted in a Randomized Complete Block Design (RCBD). Rich Farm (RF) at 200 Kg/Ha, Han Daebak (BK) at 200 Kg/Ha and Han Yoobak (MK) at 200 Kg/Ha were applied as basal fertilizers. Conventional fertilizers (200 Kg/Ha DAP + 120 Kg/Ha MOP) was applied as the positive standard check (CF). Data collected was subjected to analysis of variance (ANOVA). The basal application of Rich Farm, Han Daebak and Han Yoobak organic fertilizers had significant positive effects on grain yield. Among the tested basal fertilizers, Rich Farm performed better at 4.9 and 5.3 ton/ha, followed by Han Yoobak at 4.7 and 4.1 ton/ha and Han Daebak at 4.3 and 3.9 ton/ha in AT054 and Komboka variety, respectively. Therefore, Rich Farm and Han Yoobak can be recommended as basal organic fertilizers in both AT054 and Komboka varieties, while Han Daebak can be used in AT054 variety for rice production. Further studies are of need to investigate the effects on these organic fertilizers on the soil properties of the area, as well as evaluating the optimal rates for higher rice production

However, best results were recorded in the interaction of foliar magnesium at 1.5 gm L-1 and organic fertilizer at 15 g pot-1 with significantly the highest increase in plant height 25.56 cm and stem diameter 2.28 mm, the number of branches is 5.28 branches, seedling-1, the number of leaves is 15.00 leaves-1, the average leaf area is 3030.00 cm2, seedling-1.

Optimizing Sour Orange Growth and Chemical Properties through Foliar Application of Nano and Organic Fertilizers

This study, conducted at the Lath House of Agriculture College, Al-Qasim Green University during the 2021-2022 growth season, aimed to evaluate the effects of KHARZA nanoparticles (NPs) and organic fertilizer (Nutirgreen) on sour orange seedlings. Different concentrations of KHARZA NPs (0, 1, 2, and 3 g L-1) and organic fertilizer (0, 1.5, 3, and 4.5 ml L-1) were applied. The experimental design followed a randomized complete block design (RCBD) with two factors, each having four treatments, and each treatment replicated thrice. Our findings reveal that spraying KHARZA NPs at a concentration of 3 g.L-1 significantly enhanced various vegetative parameters, such as plant height, stem diameter, leaf number, and leaf area, alongside improvements in chemical properties such as mineral concentration, chlorophyll content, and carbohydrate levels in leaves. Similarly, applying organic fertilizer at a rate of 4.5 ml L-1 led to notable enhancements in both vegetative and chemical characteristics compared to the control group. Notably, combined application of KHARZA NPs at 3 g L-1 and organic fertilizer at 4.5 ml L-1 resulted in synergistic effects, yielding the most favorable outcomes in terms of vegetative growth and chemical properties. These results underscore the potential of utilizing KHARZA nanoparticles and organic fertilizers in enhancing the growth and physiological properties of sour orange seedlings, offering promising avenues for sustainable agricultural practices.

Effects of Mela Organics&amp;apos; New Liquid Fertilizer on Tomato Yield in Semi-Arid Areas of Ethiopia

Soil organic matter depletion is mainly caused by crop residue removal, and low or no application of organic fertilizers often results in nutrient exhaustion and low crop yields. This challenge requires the evaluation of different organic fertilizer resources to provide new alternative fertilizer products to an Ethiopian production system. Based on this fact, an experiment was conducted to evaluate the effects of mela organic fertilizer as a supplementary fertilizer to improve the yield of tomatoes under irrigation in the Central Rift Valley of Ethiopia from 2020 to 2021. The experiment consisted of eight treatments (Control, 100% recommended fertilizer, 100% recommended fertilizer + 30 L/ha Mela, 100% recommended fertilizer + 45 L/ha Mela, 75% recommended fertilizer +30 L/ha Mela, 75% recommended fertilizer + 45 L/ha Mela, 50% recommended fertilizer +30 L/ha Mela and 50% recommended fertilizer + 45 L/ha Mela) laid out in randomized complete block design with three replications. The results revealed that the highest agronomic yield was obtained by applying the 100% recommended fertilizer + 30 L/ha Mela. However, based on the partial budget analysis, the highest marginal rate of return was obtained from 50% recommended fertilizer + 45 L/ha Mela. Thus, it can be concluded that the application of Mela Organics up to 45 L/ha, integrated with chemical fertilizer applications, can increase tomatoes&amp;apos; economic yields and reduce fertilizer costs.

Effects of Microplastics and Organic Fertilizer Regulation on Soil Dissolved Organic Matter Evolution.

Microplastics are pollutants of global concern nowadays. However, the effects of microplastics addition to soil as a carbon source and the combined effects of microplastics and organic fertilizer on soil-dissolved organic matter (DOM) evolution are still unclear. This study focused on the evolution of DOM in soil with the addition of microplastics and investigated the variations in the content and composition of DOM in unfertilized and fertilized soil with different particle sizes of microplastics. It was observed that the TOC concentration of the soil DOM in the treatment with organic fertilizer and microplastics increased more (129.97-161.43 mg kg-1) than that in the treatment with microplastics alone (117.17-131.87 mg kg-1) and was higher than that in the original soil (95.65 mg kg-1). According to the humic acid relative abundance in DOM after 40 days of incubation, the humic acid relative abundance in DOM of the soil samples with microplastics and organic fertilizers addition was found to be higher than that in those with microplastic addition alone, reaching more than 80% in a short time. In conclusion, the TOC concentration of the soil DOM increased with the addition of microplastics, and the increase was more pronounced when organic fertilizers and microplastics were added together. Moreover, the soil humification increased to a higher level in the short term with the combined addition of microplastics and organic fertilizers, which was maintained during the long-term incubation process.

APPLICATION OF ORGANIC AND INORGANIC NUTRIENT SOURCES FOR IMPROVING GROWTH AND YIELD ATTRIBUTES OF MAIZE (ZEA MAYS L.) UNDER CLIMATIC CONDITIONS OF PAKISTAN

The research was conducted under rain fed conditions of Rawalakot to check the effect of different organic and chemical fertilizers on yield and yield components in maize. Eight different treatments were evaluated by using regular arrangement of randomized complete block design (RCBD) with three replications. Sheep manure (SM), farm yard manure (FYM), and poultry manure (PM) were used as organic sources of nutrients while NPK was used inorganic sources. The test variety of maize was Pioneer-30Y87. The data was subjected to analysis of variance (ANOVA) to analyze the difference amongst different means using least significance difference (LSD). Results revealed significant effect of different nutrient treatments on the yield and morphological growth of maize. Maximum number of plants (11.00), plant height (212.80 cm), number of grain rows per cob (15.60), 1000 grains weight (188.90 g), grain yield (6836.7g) were recorded for Treatment T7 (Half recommended NPK fertilizer + farm yard manure. tons ha-1). This study showed that mixed use of inorganic and organic sources of nutrients could be a better soil nutrient amendment when applied at a ratio of 50% dose of farm yard manure (FYM) + 50% dose of NPK in the cultivation of maize under rain fed conditions of Rawalakot.

Phytomanagement of cadmium using Tagetes erecta in greenhouse and field conditions

Greenhouse and field studies investigated the phytoextraction potential of soil cadmium (Cd) by Tagetes erecta L., a popular ornamental flower in Asia. The effects of organic fertilizer, cattle manure, and pig manure in supporting plant growth and enhancing Cd uptake were also examined. Plants grown in soil supplemented with pig manure produced greatest biomass (12.8 ± 1.6 and 11.8 ± 0.9 g plant−1 in greenhouse and field experiments, respectively). Plant parts accumulated Cd in the order: shoot > root > flower in all treatments. Furthermore, T. erecta had a high phytoextraction potential as evidenced by translocation factors and enrichment coefficients > 1 for shoots. Marigolds cultivated in Cd-contaminated soil supplemented with organic fertilizer (CdOrg) exhibited Cd concentrations in flowers below the Maximum Permissible Level for consumption (< 0.2 mg kg−1), indicating that the edible flowers pose no health risk to humans. The flowers additionally contained significant quantities of total phenolics and phenolic acids, which may indicate their potential as an indicator of Cd-initiated oxidative stress. The phenolic compounds can furthermore function as precursors for manufactured medicinal products by acting as antioxidants and antimicrobials. Application of organic fertilizer and selected organic amendments may have contributed to the greater concentrations of phenolics. The Cd alone treatment resulted in lowest production of bioactive compounds and antioxidant capacity. It is proposed that T. erecta be applied for Cd phytoextraction while enhancing local economies as an ornamental species, and for plant extracts for application of bioactive compounds and antioxidant capacity.

The Effect of Organic Fertilizers as Integrated Nutrient Management Practices on Morphological Characters and Yield of Tomato (Solanum Lycopersicum L.) Under open Field Conditions

The effect of organic and mineral fertilizers on the fruit yield Cucurbita pepo L.

The experiment was carried out in the vegetable field of the Department of Horticulture and Landscape Engineering, College of Agriculture, University of Karbala - Al-Husseiniyah District during the fall semester 2023-2024 in sandy soil according to a randomized completely block design (RCBD). The experiment included 19 treatments and three repetitions. Vermicompost tea was added to the soil at three levels (4, 8 and 12) liter ha-1, and humic extract was added at three levels as well (6, 12 and 18) liter ha-1. It was added to the soil in three batches, and three levels of NPK mineral fertilizer (25%, 50%, and75%) of the fertilizer recommendation with compared to a treatment to which the full fertilizer recommendation(100%) NPK)Comparison (,was applied in three stages to investigate the impact of vermicompost tea humic acid and mineral fertilizer (NPK) on the quality of zucchini squash The results showed a significant effect of the highest concentration of vermicompost tea and mineral fertilizer 75% on the characteristics of fruit length and fruit weight, as treatment F12 excelled by giving it the highest rate of the mentioned characteristics, amounting to 18.90 cm and 210.90 g fruit -1, and treatment F10 recorded the highest rate of fruit number characteristic of 5.63 fruit-1. The results also showed that the F3 treatment was superior in terms of fruit diameter, reaching 4.132 cm. We conclude from this that it is preferable to divide the organic and mineral fertilizers into batches, and it is possible to use quality organic fertilizer with a third of the amount of mineral fertilizer, that is, reducing mineral fertilizers and replacing them with organic fertilizers.

The Effects of Organic Fertilizers and NPK on Growth and Yields of Cowpea (Vigna unguiculata. L) in Kano Plains Kisumu, Kenya

Excessive use of inorganic mineral fertilizers as an agronomic practice has resulted in the depletion of soil organic matter of soils of many regions thereby rendering such soils infertile and unable to maintain sustainable production. The use of organic amendments provides the immediate strategy for compensating for soil carbon depletion thereby reducing land degradation. The purpose of this study was to evaluate the effects of six organic amendments on the growth and yield of Cowpea (Vigna unguiculata L) as compared to the conventional use of inorganic fertilizer NPK. The organic amendments were Boom Max, Ecoplanting, Evergrow, Dung slurry, Filter mud, and Market waste slurry applied to the soil at 8.33 t/ha against NPK (9:15:20) at 250 kg/ha. The experiment was laid in a RCBD. Data on growth and yields was collected on 10 tagged plants per plot. The results showed differences among treatments. Mature composts (Boom Max, Ecoplanting, and Evergow) resulted in a significantly (p&lt; 0.05) higher germination percentage (53.49% on average) compared to that of Filter mud (41.50%) and the slurries (34.18% on average) while all the composts resulted in 25% higher number of branches on the average in season two as compared to the bio-slurries. In season three, Boom Max gave the highest germination percentage (41.02%) which was significantly higher than those of Evergrow (29.80 %), Filter mud and Dung slurry (27.18% on average) and NPK and Market waste slurry (5.64% on average) but not different from that of Ecoplanting. Five of the amendments had significantly better germination rates than NPK by an average of 20%. There were no significance differences (P≤0.05) in growth parameters between the mature composts and the NPK fertilizer, suggesting that the mature composts were equally efficient in nutrient supply to the crop as did the NPK fertilizer for plant growth. The application of organic amendments produced significant improvements in fresh leaf yields of the cowpea crop, with the highest yield recorded from the Boom Max applied plot (5781 kg on average), which was not different from others in seasons one and three but significantly different from that of NPK in season three. It can be concluded that depending on choice or type of amendment, organic manures are capable of producing similar or better results of crop growth and yields as the inorganic fertilizers.
