This research is a field experiment conducted in Belancan Village, Kintamani District, Bangli Regency from April to December 2017. This study used a Randomized Block Design (RBD) with 2 factors arranged factorial. Thus in 10 combinations were repeated three times so that in 30 polybags the treatment combination. The interaction between the treatments of chicken manure with citrus varieties (A × J) significantly affected the shoot wet weight variable and the open dry weight variable. The highest wet weight value obtained in the treatment of chicken manure doses of 62.5 grams per polybag (A4) is 57.83 (g) increased 629% when compared to the lowest yield in the treatment of chicken manure 0 grams per polybag (A0) which is only 7.93 (g). In the treatment of shoots wet weight orange varieties obtained the highest value in the tre...
Yield and quality of fruits of Valencia orange are influenced by using an N fertilization, the excessive use of N fertilizer can accumulate harmful nitrate in fruit and soil. During the two successive seasons 2011 and 2012 this study was carried out on 12 years old Valencia orange trees budded on sour orange cultivated in the experimental farm of faculty of Agricultural south valley Univ., with clay Loam soil texture, at Qena Governorate. to evaluate the behavior of three kind of biofertilizers namely Azotobacter choococcum, Bacillus megaterium and Bacillus circulans, adding 140 or 180 units of nitrogen combined with 120 units of potassium and their effects on vegetative growth, leaf mineral content, yield and fruit quality. The obtained results showed that, the growth parameters increased significantly when added Bacillus circulans with 180 units of nitrogen than adding the same biofertilizer with 140 units of nitrogen. Whereas, adding 140 units of nitrogen/feddan without biofertilizer gave a lower effect for the same traits. The increment of yield / trees was about 18.32 % and 17.97 % with Bacillus circulans, 9.08 % and 8.54 % with Bacillus megaterium while the lowest values observed in Azotobacter which were 6.31 % and 6.60 % during the first and second seasons with 180 units of nitrogen. Chemical composition of fruit juice such as T.S.S, Acidity, T.S.S, Acid ratio and sugar were increased under the lower level of nitrogen, except V.C. and Total carotenoids. Hence, it can be concluded that using Bacillus circulans under the highest and the lower levels of nitrogen combined with 120 units of potassium was very effective than the other kind of biofertilizers.

Chicken manure and farmyard manure are relatively rich in content of nitrogen and has T HE present study was carried out as a pot experiment during the 2017 and 2018 seasons at the fruit nursery in Faculty of Agriculture, Zagazig University, Egypt to assess the mixing of two types of organic fertilizers (chicken manure and farmyard manure) with sandy soil at 10% by weight on growth and the physical and chemical characteristics of seedlings of sixmonth-old for three citrus rootstocks are Sour orange, Volkamer lemon and Troyer citrange to reach the suitable size of grafting in the shortest possible time. The results revealed that the highest values of leaf area and leaf fresh and dry weights were recorded for Sour orange seedlings, while the number of leaves/ plant, shoot numbers/plant and stem diameter gained by Vokamer lemon, followed by Troyer citrange. Seedlings treated with chicken manure achieved the largest leaf area, total number of leaves/ plant, leaf fresh and dry weights, stem height and diameter, photosynthetic pigments and N, Fe, Zn and Mn but shoot numbers/plant, P and K came by farmyard manure.
