“…Frequent and high rate uses of inorganic fertilizer have been associated with some environmental pollution, alteration in soil textures and physical property of the soil. Moreover, the nutritional value of the crops will be affected seriously by the continuous use of synthetic fertilizer [3] also inorganic fertilizers will increase the cost of crop production. Now, throughout the world, the demand for organic foods is increased among the consumers that are good for health and the environment.…”

Abstract. In the present study, a field experiment was conducted to study the effect of some organic fertilizers on four varieties of tomato viz., Sadia F1, Isabella F1, Lelord and Sun cherry for its growth, yield and fruits sensory. A total of 64 plots were prepared with the dimension of 3 m 2 x 4 m 2 and each plot was applied with recommended doses of organic fertilizers. The results on the growth parameters of the studied tomato varieties showed that the chicken manure had the significant effect on plant height and root length of Isabella F1, leaf area of sun cherry, root fresh and dry weight and of Lelord, leaves fresh and dry weight of Sadia F1. Whereas, shoot fresh and dry weight of Isabella tomato variety was increased when treated with mixed manure. Agro fish pellet treatment had increased the stem diameter of Isabella F1 significantly. The number of flowers and fruits of sun cherry tomato variety were increased when treated with agro fish pellet. Agro fish also influenced the fruits number in Sadia F1 and fruit yield of lelord followed by Isabella F1 respectively. The sensory evaluation of the fruits of studied tomato varieties revealed that chicken manure had good result on the overall quality of the fruits of Sadia F1 and Sun cherry. Agro fish pellet and mixed manure has influenced the overall quality of Isabella F1 and Lelord variety tomato fruits.

“…The quality and quantity of applied fertilizers are key factors affecting the growth, yield, and quality of crops (Chang et al, 2010). However, the continuous use of chemical fertilization leads to the deterioration of soil characteristics and fertility and might lead to the accumulation of heavy metals in plant tissues, affecting the fruit nutritional value and edibility (Shimbo et al, 2001). The application of organic fertilizers, which are made from animal excreta or other agricultural wastes, contributes to the sustainability of agriculture systems and is usually used to improve the soil structure and stability in addition to enhancing the yield and, in particular, the quality of plants (Tejada and Gonzalez, 2003;Abou El-Magd et al, 2006;Chang et al, 2010;Marzouk and Kassem, 2011).…”

A field experiment was conducted to investigate the influence of the addition of organic manure on the maturity stage and quality of pineapple fruits ripened in winter. Fertilization was performed with 200 mL peanut-press pulp liquid fertilizer + 20 g compound fertilizer per plant (T1) or 100 mL peanut press pulp liquid fertilizer + 20 g compound fertilizer per plant (T2). Fertilization with 20 g compound fertilizer per plant (T0) was used as the control. The results indicated that organic fertilizer addition promoted maturity. The weight per fruit was increased, and the contents of TSS and total sugars were enhanced, whereas the titratable acid contents were decreased. A sensory evaluation indicated that, after the addition of organic manure, the pineapple fruits were sweeter and more fragrant. More types of ester aroma components having a higher total relative content were identified in T1, and more types of alkenes having a higher total relative content were identified in T2. The relative contents of propanoic acid, 3-(methylthio)-, and methyl ester were increased by organic manure treatments, with the highest being noted in T1 (5.79%), followed by T2 (5.59%), and the lowest was documented in T0 (4.36%).

“…International comparison on Cd-R was conducted twice and reported in three articles [16][17][18] including one 18) on Japanese cases, and two 16,17) of them are summarized in Table 1. It should be noted that the sampling was by chance with no rigid statistical strategy such as random sampling, that the samples were rice for consumption by local people and were not necessarily harvested on sites and that the numbers of samples were as small as 5 in some cases.…”

Cadmium (Cd) intake via diet (Cd-D) has been a long-standing focus of administrative as well as public concern in Japan after the endemic of Itai-itai disease (chronic cadmium poisoning). The aim of this report was to review cadmium exposure in Japan by introducing publications from our study group and related articles. Literature survey disclosed that Cd-D was high (up to 100 µg/day) in 1960s even in non-polluted areas. Such high Cd-D levels were followed by gradual decreases in 1970s-1980s to current level of well below 20 µg/day. Once, a very high Cd-D (600 µg/day) was reported for a Cd-polluted area. Replacement of Cd-polluted rice paddy soil with clean soil resulted in substantial reduction in riceassociated Cd-D. In large-scale surveys in 10 prefectures all over Japan conducted early in 2000s, the geometric mean (GM) of Cd-U cr (Cd in urine as corrected for creatinine concentration) was 1.26 µg/g cr, but was higher in one north-west sea coast prefecture in Honshu Island (>3 µg/g cr). Supplemental survey in 6 neighboring prefectures on the sea coast disclosed that Cd-U cr in some prefectures were higher as compared with the national average. It was reported that Cd in brown rice was also high. However no clear-cut indication was detected to suggest renal tubular dysfunctions. Surveys in major cities in East and South-East Asia in 1980s-1990s made it clear that Cd-D was substantially lower there than in Japanese cities; Cd exposure of general populations was almost exclusively from foods. Statistical analysis revealed that tubular dysfunction markers increased sharply when Cd-U cr exceeded 10-12 µg/g cr. The Cd-U cr level of 11 µg/g cr corresponded to Cd-D level of 59 µg/day. This level was in agreement with the tolerable weekly intake of 7 µg/kg body weight/week, the value recommended by the Food Safety Commission of Japan.
