“…Similarly, biofertilizer significantly increased T.S.S and decreased juice acidity of flame seedless grapevines [30]. Treatment combinations of organic and biofertilizer showed the highest total soluble solids and total sugar content of fruit [53]. This result may be due to the fact that organic fertilizers are rich in their content of macro and micro elements which led to enhance photosynthesis; this means that more sugar (glucose) is available for growth and fruit ripening [54].…”

The application of some biofertilizers and irradiated compost for replacement of NPK chemical fertilizers was studied on fiveyear-old superior seedless grapevine to determine the best dosage that would improve growth, yield and berry characteristicsand reduce the rates of mineral fertilizations of NPK without any negative effect. The experiment was conducted in a vineyard located at Cairo-Alexandria Desert Road in 2015 and 2016 seasons. The experiment consisted of six treatments, namely, 100% NPK (control), 100% NPK + microbein, 50% NPK + 50% irradiated compost (IC), 50% NPK + 50% irradiated compost + microbein, 100% irradiated compost and 100% irradiated compost + microbein. All treatments were very effective in stimulating growth characters as well as physical and chemical characteristics of the berries in relation to the control tre atment. Petiole NPK %, leaf chlorophyll content and cane carbohydrate content were increased more than the control. In addition, the cluster weight was significantly increased and as a result, yield per vine was increased. The highest superior effect was recorded in response to 100% IC + microbein application. This improvement could be attributed to the positive influence upon the biosynthesis of the primary metabolites (soluble carbohydrates, chlorophyll and carotenoid pigments) and secondary metabolites (proteins, polyphenols, auxins). In addition, both compost especially when irradiated and biofertilizers increase the availability and uptake of N, P and K, which was reflected on the growth parameters. Finally, irradiated compost alone or combined with microbein could be used as a valid alternative method to the expensive hazardous mineral fertilizers.

“…Similarly, Mostafa et al (2011) reported that compost tea improves quality of grapes. In addition, Dutta and Kundu (2012) found that bio-fertilizers are effective in fruit quality (TSS, total sugar and vitamin c) and decreased total acidity of mango and Devi et al (2012) found the same results in Litchi.…”

“…To reduce both high costs and environmental pollution of using mineral fertilizers, many researches resorted to new attitude by using organic manures and biofertilizers instead of chemical ones. This was documented on common guava by Mitra et al, (2010), Wali et al, (2011), Barue et al, (2011), Devi et al, (2012), Yadav et al, (2013), Hernandez et al, (2013), Binepal et al, (2013), Nunes et al, (2014)and Ram et al, (2014), as they all affirmed that the combined application of organic and inorganic manures along with biofertilizers gave better results than their individual application giving better economic response.…”

Furthermore, Devi et al, (2012) concluded that application of FYM at 26 kg/tree/y + azotobacter (100 g/tree) + P-solubilizer (100 g/tree) + K-mobilizer (100 g/tree) in two splits (January and August) is the economically profitable treatment for cultivation of guava cv. "Sardar".…”

A series of field experiments was carried out in a private orchard at Qalyob region, Qalubia governorate, Egypt during 2011/12, 2012/13 and 2013/14 seasons for winter production of 9-years-old guava (Psidium guajava L.) cv. "Etmani" trees, planted on clay loam soil at a distance of 5 x 5 m and fasted from April, 1 st to July end, beside improving yield and quality of such winter crop by application of organic compost at either full, ¾ or ½ the recommended dose (40, 30 and 20 kg/tree, respectively) + both feldspar and rock phosphate at either full, ¾, ½ or ¼ the recommended dose for each + biofertilizer mixture comprising nitropeine + phosphoreine + potasseine at the recommended dose for each, where all previous compost were arranged in 12 combinations plus the control. The gained results have shown that most fertilization treatments employed in this work raised the means of shoot length, number of leaves/m, leaf area and number of flower buds/m over those of control with various significant levels in the 3 seasons. Similarly, were those results of No. of fruits/m, fruit weight, yield, fruit length, diameter and volume, as well as flesh thickness. The prevalence in all aforenamed characters was for the combination of 75 % compost + 100 % feldspar + 100 % rock phosphate + biofertilizers mixture which gave the utmost high means over control and other combinations in most cases of the three seasons. The percent of TSS was significantly increased in the first season only by 100 % compost + 25 % feldspar + 25 % rock phosphate + biofertilizers mixture combined treatment, but in the 2 nd and 3 rd seasons, it was slightly improved by the different used combinations with nonsignificant differences in between or with control. The acidity % exhibited a similar behaviour in the three growing seasons, but the least percent of acidity was found due to the combining between 100 % compost, 25 % feldspar + 25 % rock phosphate and biofertilizer mixture (T4), especially in the 1 st and 2 nd seasons. In the 3 rd season, however, the least acidity % was attained by 75 % compost + 100 % feldspar + 100 % rock phosphate + biofertilizer nixture (T5). So, the best ratio of TSS/acidity was obtained in the first and second seasons by T4, while in the 3 rd one by T5. Vitamin C content and flesh thickness were also improved by the used fertilization combinations, but the highest records of them was obtained by different treatment in every season. The percent of N, P, K, Ca and Mg in the leaves of fertilized plants was, in general improved over that of control in the three seasons by the different used treatments, but no one of them had the superior effect over the others. Hence, it can be advised to fertilize the 9-years-old trees of guava cv. "Etmani" grown on clay loam soil at 5 x 5 m apart under Qalubia governorate conditions and fasted from April, 1 st to end of July with 75 % of recommended compost dose (30 kg/tree) + 100 % of both feldspar (1.2 kg/tree) and rock phosphate dose (1.3 kg/tree) plus biofertilizer mixture used in this study t...
