The aim of this study was to examine the influence of fertilization on nitrate, nitrite, and vitamin C contents in vegetables. All seedlings (mustard, bokchoy, spinach, and lettuce) were grown in the greenhouse in polybags with organic and inorganic fertilizers. Nitrite was derivitized with sulfanilic acid and N-(1-naphthyl) ethylenediamine dihydrochloride in acetic acid solution, then absorbance measured by spectrophotometer at 540 nm. Nitrate reduced to nitrite by adding zincum powder in acidic condition, then determined as nitrite. Vitamin C was titrated with 2,6-dichlorophenol indophenol.The study show that the influence of organic fertilizers increased nitrate, nitrite and vitamin C contents with increasing doses. Inorganic fertilizers was found to be more influential to increase nitrite and nitrate contents, but decreased vitamin C with increasing doses.This findings suggest that inorganic fertilizers more effective to increase nitrate and nitrite contents compared to organic fertilizers. Organic fertilization increased vitamin C, but inorganic fertilization decreased.

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..

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.

The organic amendments, composts (1, 2, 3), neem and poultry as well as inorganic fertilizers (NPK compound and commercial, Athree®) and the nematicide nemacur 10 G applied singly were effective in reducing M. incognita number of galls, nematode reproductionand fecundity. The effectiveness seemed to be material origin dependent. Neem, compost 1, 3 (5 g/pot) gave the best results. Yet, achievedresults were less than those of nemacur 10% G. The antioxidant substances content and enzymes activities due to nematode infectionand application of organic and inorganic fertilizers pointed to significant increase of lipid peroxidation and hydrogen peroxide as aresult of nematode infection and nemacur treatment. While all organic and inorganic fertilizers reduced such materials with significantdifferences among treatments. Likewise, nematode infection resulted in slight but significant increase in glutathione and ascorbic acidin tomato shoots and roots. All treatments increased antioxidant substances comparing to healthy and infected plants. Glutathione-Stransferaseactivity highly increased in infected roots but the lowest activities were achieved by organic fertilizers. Nematode infectionand nemacur treatment increased slightly phenylalaine ammonia lyase activity but enormous increase was observed in shoots and rootsof treated plants with organic fertilizers followed by NPK treatments.
