“…Similar results were also discovered on winter crop of guava by Bshir et al, (2009), El-Sharkawy and Osman (2009), Dwivedi et al, (2012) and Elmehart et al, (2012) whom claimed that combining between 75 % recommended NPK fertilizers and biofertilizers (PGPR) at 9.52 l/ha gave the best results for weight loss, decreasing firmness and decay, increasing vitamin C, TSS, sugars, improve colour and decreasing total acidity as compared to fruits of untreated trees.…”

“…Similar results were also attained by El-Shobaky 2007, Bashir et al, (2009), El-Sharkawy and Osman (2009), El-Baz et al, (2011) and Dwivedi et al, (2012) on winter crop of guava. 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.…”

“…These gains may be interpretted and discussed as done before in case of vegetative growth, yield and fruit characteristics. Analogous findings were also detected on winter guava by Mikhail et al, (2007), Dashora et al, (2007), Bashir et al, (2009) and Dwivedi et al, (2012) who suggested that improving physical and chemical characteristics of guava fruits may be attributed to the better vegetative growth of the fertilized plants which resulted in higher quantities of photosynthates (starch, carbohydrates, … etc) and their translocation to the fruits, thus improving the various quality parameters. Application of P-solubilizers significantly influenced vitamin C content in guava over the control during winter season.…”

“…"Etmani" (Part, I). In this connection, Dwivedi et al, (2012) mentioned that increasing "Red Flashed" guava growth may be attributed to increase in level of readily available N, P, K and other nutrients in the presence of organic manure which often enhanced growth mechanism in plants. Increasing soil chemical and physical properties that were induced by organic manure application may be a direct reason for improving growth (Muhammad et al, 2000).…”

“…This may be comprehensible because this combination gave the best vegetative and flowering growth throughout the three growing seasons as indicated before in Table (4), and that was usefully, reflected on increasing yield and improving fruit characteristics. In this regard, Dwivedi et al, (2012) mentioned that application of biofertilizers in the presence of organic manure was more effective in enhancing fruit growth parameters due to the increased availability of nutrients which might have reflected the increase in fruit weight, length and breadth.…”

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...
