Foliar Feeding of Different Levels of Boron and Zinc on Physico-Chemical Characters and Economics of Winter Season Guava (Psidium guajava L.) Cultivar L-49

Effect of Ethereal and Nano fertilizers foliar application on yield and fruit quality of Alphonse mango

“…The lowest values were recorded on untreated trees. This finding is in line with that reported by Maurya (2004); Singh and Maurya (2004); Nehete et al (2011);Hada et al (2014); Venu et al (2014); Gurjar et al (2015) revealed that foliar application of 1% ZnSO4, 1% FeSO4 and 0.5% borax in combination had influenced flowering at pea stage and marble stage of alphonso mango and Zagzog and Gad (2017) they found that spraying Zebda and 'Ewasy' mango trees with Nano-zinc at 1g/l before flowering improved sex ratio.…”

“…As for the treatment of 110 ppm Nano Si+ 110 ppm, Nano Zn recorded the maximum value of Perfect flowers percentage in the first season but in the second season treatment with 500 ppm Etherl + 110 ppm Nano Si+ 110 ppm Nano Zn recorded the highest values. This finding is in line with that reported by Hada et al (2014);Maurya (2004); Singh and Maurya (2004); Nehete et al (2011), Venu et al (2014; Gurjar et al (2015) they revealed that foliar application of 1% ZnSO4, 1% FeSO4 and 0.5% borax in combination had influenced flowering at pea stage and marble stage of alphonso mango and Zagzog and Gad (2017) they found that spraying Zebda and 'Ewasy' mango trees with nano-zinc at 1g/l before flowering improved sex ratio. treatment data in Table 3 show that single and combined foliar applications of Ethrel and Nano fertilizers increase shoot length and leaf area significantly more than the Check treatment.…”

“…In similar studies of using zinc on citrus fruiting, Sajid et al (2010); Khan et al (2012); Baghdad et al (2014); Venu et al (2014); Ilyas et al (2015); Gurung et al (2016) they concluded that foliar application of GA3 at the rate of 15 ppm along with zinc at 0.5% and boron at 0.1% enhanced the fruit yield of Darjeeling mandarin. Also, in similar studies of using combined zinc on guava fruiting, Hada et al (2014) and Kumar et al (2015) reported that the foliar fertilization of Pant Prabhat guava showed an increasing trend toward yield kg/tree with 0.01% Zn two weeks after fruit set while it showed a trend towards decreasing fruit drop with 0.03% Zn two weeks after fruit set. Several authors agreed that using combined zinc on fruiting was beneficial Sayyad-Amin et al (2015) found that the most yield of olive was seen in the foliar spray of zinc sulfate at 2000 mg l-1 and boric at 2000 mg l-1 alone, respectively.…”

Effect of foliar spray of silicon and boron on fruit quality and shelf life of rejuvenated mango (Mangifera indica L.) cv. Sonpari

“…These results are in agreement with the findings of Anees et al (2011) [4] and Chauhan et al (2014) [9] in mango, Awasthi and Lal (2009) [6] and Yadav et al (2011) [28] in guava. Minimum value of acidity content with boric acid treatment might be due to fastly converted into sugars and their derivatives by the reaction involving the reversal of glycolytic path way or might have been used in respiration (Hada, 2013) [11] in guava. Higher value of ascorbic acid content in fruit might be due to the possible influence of boron on biosynthesis of ascorbic acid from sugars or inhibition of oxidative enzymes or both.…”

Value addition of guava candy (Psidium guajava. L) cv. Allahabad Safeda

“…This fruit is widely known as the "apple of the tropics" and is highly regarded in India's agricultural industry. It is considered one of the most popular and widely cultivated fruits in the country, second only to mango, banana, and citrus fruits (Hada et al, 2014) [6] .…”
