A field experiment was conducted at Jimma Agricultural Research Center, Agaro Agricultural Research Sub Center, southwestern Ethiopia for five consecutive cropping seasons from 2015/16 to 2019/20 to evaluate effect of organic (conventional compost) and inorganic NP fertilizers on agronomic growth and soil properties of coffee (Coffea arabica L.). The treatments consisted of 100% recommended decomposed coffee husk alone, 100% recommended NP rate alone, 100% of NP + 25% of compost (DCH), 75% of NP + 50% of compost (DCH), 50% of NP + 50% of compost (DCH), 50% of NP + 75% of compost (DCH), 25% of NP + 75% of compost (DCH), 25% of NP + 100% of compost (DCH) and Control (without input, farmers’ practice). The experiment was laid out in randomized complete block design with three replications. Higher yield of clean coffee yield was obtained from the application of 50% dose of nitrogen and phosphorous from inorganic fertilizer sources and 50% dose of decomposed coffee husk (2083.5kg ha-1) while the lowest clean coffee yield (1570.5kg ha-1) was obtained from no application of fertilizers. Application of organic fertilizers (compost) with inorganic fertilizers gave statistically similar yield components to NP fertilizer alone for five years. Significant differences (p>0.05) due to soil nutrient sources were observed in coffee height where inorganic fertilizer treatment resulted in tallest coffee plants (348.23 cm) and no application of nutrients having the shortest coffee trees (200.49 cm) after two year. Lower yield and yield components of Limu1 coffee were achieved from no application of organic and inorganic fertilizer sources. In conclusion, organic fertilizers (conventional compost) alone cannot provide a viable substitute for inorganic fertilizer without causing a significant yield. Therefore, integrated use of organic and inorganic fertilizers was recommended for coffee production at Jimma, southwestern Ethiopia and other similar agro ecology.

Organic And Inorganic Fertilizers

Rice is the most important staple cereals in human nutrition and consumed by 75% of the global population. Rice plant needs supply of essential nutrients for its optimal growth. Rice production has been increased tremendously in India after green revolution combined with insensitive irrigation and use of inorganic fertilizers and pesticides. However, the effect of using inorganic fertilizers has resulted in contamination of ground water and decreased the productivity of soil, which in turn affects the rice production in long term. Use of organic manure may help to regain the soil health but they are insufficient to provide the essential nutrients to achieve optimal growth. So, use of organic manures combine with inorganic fertilizers are followed to obtain optimum yields. This study aimed to test the effect of the different organic fertilizer and combinations of organic and inorganic fertilizers on the qualitative and quantitative parameters of two cultivars of rice as DRR Dhan 39 and RP.BIO.226. The experiment was conducted on the farm located at Fasalwadi village, Sangareddy district, Telangana during kharif season in randomized complete block design with three replications. The treatment included two controls and 10 combinations of four organic fertilizers as farmyard manure, vermicompost, Panchagavya, Jeevamrutha and inorganic fertilizers as combination of 60:75:75 levels of N, P and K. Grain and straw samples were collected and physical parameters were measured at harvest stage. The results indicated that the variety DRR Dhan 39 gave the statistically significant (P<0.0001) higher grain yield of 8713 kg/ha and straw yield of 9483kg/ha with 50% organic fertilizers of Vermicompost, Jeevamrutha 5% and Panchagavya 3% and 50% inorganic fertilizer of NPK. On the other hand, the variety of RP.BIO.226 gave the highest grain yield of 6390 kg/ha with Vermicompost, Jeevamrutha 5% and Panchagvya 3% (8 t/ha, foliar spray and 500 litres/ha) and highest straw yield of 7430 kg/ha with T10 treatment (50% organic fertilizers of Vermicompost, Jeevamrutha 5% and Panchagavya 3% and 50% inorganic fertilizer of NPK). Both varieties of rice poorly responded to inorganic fertilizers with lower grain and straw yield. Statistically significant differences were observed in both varieties of grain crude protein (CP%), straw acid detergent fiber (ADF%), crude fiber (CF%) and acid detergent lignin (ADL%) with different fertilizers

[CABBAGE (Brassica olacea var. capitata) GROWTH AND YIELD AFFECTED BY COMBINATION OF ORGANIC AND INORGANIC FERTILIZER APPLICATIONS]. The use of organic fertilizer increasingly sought by farmers due to the increase in demand for organic products by consumers and also awareness of the sustainability of the land. The use of organic fertilizers in the cultivation alone could improve the soil quality but needs to be balanced with inorganic fertilizers to meet the nutrient adequacy. This study aims to examine the effect of organic and inorganic fertilizers combination on the growth and cabbage yield, and also to determine the most efficient dosage combination of organic and inorganic fertilizers. This research was conducted at the IPB Pasir Sarongge Experimental Station, Cianjur, West Java from November 2020 to February 2021. The study was compiled using RCBD with 4 replications and 7 treatments. The results showed the combination of 0.75 doses of inorganic fertilizer (150 kg/ha of urea, 75 kg/ha SP36, and 75 kg/ha KCl) and 3 tons/ha of organic fertilizer could increase 14.87 to 15.44% plant height and the number of leaves at 12.82 -15.11% compared to the same dose of inorganic fertilizer treatment alone. The combination of 1 dose (200 kg/ha of urea, 100 kg/ha SP36, and 100 kg/ha KCl) inorganic fertilizer application and 2 tonnes/ha of organic fertilizer could increase 50,60% yield/plot and yield/ha cabbage than 1 dose of inorganic fertilizer treatment..

Abstract This study explores the causal association between organic and inorganic fertilizer application and vegetable productivity in Ghana. Primary data were obtained from 300 pepper, cabbage and lettuce producers. To correct for self-selection bias and endogeneity, Heckman selection and three-stage least-squares models were estimated. More producers used inorganic fertilizers for pepper, cabbage and lettuce production than those who used organic fertilizers. Vegetable producers applied higher quantities of organic fertilizers (2830 kg) per acre than inorganic fertilizers (880 kg). Organic cabbage and lettuce producers recorded higher productivity than inorganic producers, but inorganic pepper producers had higher productivity than organic producers. However, vegetable producers who applied either organic or inorganic fertilizers, or both, recorded higher productivity than those who did not apply fertilizer. Factors that enhance the application of organic and inorganic fertilizers and vegetable productivity are education, farm size and production for export, land ownership, farmer association membership and perception about fertilizer price. Organic and inorganic fertilizer application improves vegetable productivity, and productivity promotes fertilizer application. Private agencies and government should subsidize fertilizers, improve producers' access to agricultural information, and train producers on productivity-enhancing agronomic practices.

Organic And Inorganic Fertilizers

Organic farming is being promoted by advocates to sustain and improve soil fertility compared to conventional farming that uses inorganic fertilizers and pesticides. The study was conducted to determine the effect of pesticide and fertilizer management practices on grain and straw yields, yield components, and soil fertility of irrigated lowland rice. The experiment was conducted for three consecutive seasons (2009-2010) at Los Baños, Laguna, Philippines. It was laid out in a Split Plot design consisting of two main plots: with pesticides (M1) and without pesticides (M2), and four subplots: control (T1), organic fertilizer only (T2), inorganic fertilizer only (T3), and one-half (½) rate of inorganic plus ½ rate of organic fertilizers (T4), with four replications. Generally, pesticide application did not affect the yield and yield components. Plots applied with inorganic and one-half rate of combined organic and inorganic fertilizers had significantly higher grain yields than the control and organic only fertilizer treatments. Application of limiting nutrients through inorganic fertilizers helps to correct most of soil deficiencies such as phosphorus and sulfur compared to the use of organic fertilizer alone. Combining organic materials such as compost and rice straw with inorganic fertilizers at one-half rates is an effective strategy to attain yields comparable to pure inorganic application to sustain soil fertility.

The study was carried out to determine the influence of organic and inorganic fertilizers on maize yield and soil fertility; to determine economically optimum organic and inorganic fertilizer combinations for maize production. The study was performed in a randomized complete block design consisting of 10 treatments and 3 replications. The treatments were: Control, 100% of R-NP (138 N and 92 P), 100% of vermicompost,100% of conventional compost, 25% R-NP +75% of vermicompost, 50% of R-NP + 50% of vermicompost, 75% of R-NP+25% of from vermicompost, 25% of R-NP +75% of conventional compost, 50% of R-NP+50% of conventional-compost, 75% of R-NP +25% of conventional-compost. All rates of vermicompost and conventional compost were applied based on N equivalence. Results indicate that applications of inorganic fertilizers with a combination of organic source fertilizers were increases maize yield and yield components and improves the nutrient status of the soil. The highest maize grain yield (7494.3 kg ha-1) and above-ground biomass yield (18718.0 kg ha-1) were obtained from the applications of 50% recommended NP fertilizer plus 50% vermicompost which is based on the recommended N equivalent respectively. Similarly, we found that a combination of both inorganic and organic fertilizers application also is the best strategy to improve major soil nutrients, maintain soil fertility. The economic analysis revealed that the highest net benefit of (108,872.0 ETB ha-1) was obtained from the application of 50% recommended NP fertilizer plus 50% vermicompost based on the recommended N equivalence. Yet, the lowest yield and net benefit value were attained from the control or unfertilized plot. Therefore, this study suggests that an appropriate proportion of organic fertilizer with inorganic fertilizer not only for higher yield maize production with an assurance of potential economic returns to the small hold farmers but also improve and maintain the soil fertility and should be adopted with similar soil type and agro-ecologies.

Tuberose (Polyanthes tuberosa L.) is a potential flowering plant that will be developed in Jatinangor, West Java, Indonesia. However, the characteristics of Typic Hapludult soil in Jatinangor , i.e. clay texture, acidic pH, and high amount of total-P but low in available-P cause the tuberose difficult to grow optimally. The aim of this study was to obtain the potential ratio of organic and inorganic fertilizer dosages for tuberose grown on Typic Hapludult. The combinations of organic and inorganic fertilizers with different ratios (0/0; 0/1; 1/0; 0.5/0.5; 0.5/1; 1/0.5; 1/1.5; 1.5/0; 1.5/0.5, and 1.5/) were applied. The application of the combination of organic and inorganic fertilizers showed positive effects on soil pH, available-P, total-P, and fresh weight of tuberose grown on Typic Hapludult. The application of 50% organic fertilizer + 50% inorganic fertilizer was an effective combination that was able to increase the fresh weight of tuberose up to 9240 g plant-1 or increasing the fresh weight by 39% in comparison to that in the control treatment (without fertilizer application).

Crop and nutrient management options could improve the yield performances of late transplant Aman rice which is generally lower compared to optimum transplanting. To address these issues, an experiment was conducted at Bangladesh Agricultural University, Mymensingh to investigate the effect of spacing and nutrient management options on yield and yield components of late transplant Aman rice and to find out the better treatment combination to obtain higher yield. The experiment was laid out in two factors randomized complete block design (RCBD) with three replications consisting of three spacings viz. S1 =25 cm×15 cm , S2 =25 cm×10 cm and S3 =20 cm×10 cm; and eight nutrient management options viz. N0 = Control (No fertilizer), N1 = Poultry manure @ 5 t ha-1 , N2 = Vermicompost @ 3 t ha-1 , N3 = Researcher’s practice (Urea, TSP, MoP, Gypsum and ZnSO4 @ 180,75,105, 60 and 7.5 kg ha-1, respectively), N4 = 75% N3 + Poultry manure @ 2.5 t ha-1, N5 = 50% N3+ poultry manure @ 5 t ha-1, N6 = 75% N3+ Vermicompost @ 1.5 t ha-1 and N7 = 50% N3+ Vermicompost @ 3 t ha-1. Pre-germinated seeds of BRRI dhan46 were sown in wet nursery bed on 16 August and 30–d–old seedlings were transplanted as per treatments on 15 September in 2017. Yield and yield components were significantly influenced by spacing, nutrient management options and their interactions. The highest yield (5.20 t ha-1) was obtained the spacing 25 cm×10 cm which was at par with 25 cm×15 cm (5.12 t ha-1) and the lowest (4.88 t ha-1) was in 20 cm×10 cm. Statistically similar grain yield 5.85, 5.81 and 5.79 t ha-1 were produced in the treatments N3, N4 and N6, respectively. Grain yield increased in the treatments having combination of inorganic and organic nutrient, and also in the optimum inorganic fertilizers (researcher’s practice). The highest grain yield (5.98 t ha-1) was obtained in the interaction S2×N3 which was at par with S1 x N3, S1 x N4, S1 x N6, S2 x N4 and S2 x N6. Performances of sole organic fertilizers were not satisfactory level. Therefore, reduced amount (75%) of inorganic fertilizers combined with organic fertilizers (poultry manure 2.5 t ha-1 or vermicompost 1.5 t ha-1) along with closer spacing 25 cm×10 cm would be recommended to achieve better and sustainable yield performance of late transplant Aman rice cv.
