“…In the same pattern, for mixed treatment, the number of fruit formed in the mixture of cytokinin and gibberellin was relatively lower than that of auxin and gibberellin. Another research on two varieties of mango plants for two years by Nkansah et al (2012) found that mango plants sprayed with 25 ppm GA3 and 25 ppm NAA produced the highest number of fruit per plant compared to other treatments. However, both mixtures had the same pattern that the highest number of fruit was obtained in a balanced mixture of cytokines and gibberellin (P6 = BAP 150 mg.L -1 + GA3 150 mg.L -1 ) or of auxin and gibberellin (P9 = NAA 150 mg.L -1 + GA3 150 mg.L -1 ).…”

Plant growth regulators have a significant impact on increasing both quality and quantity of plant yield for either mixed or separated application. The research was aimed to identify the effect of spraying plant growth regulators on duku flowers for fruit formation. The research was conducted from December 2014 to May 2015 in Sijacarana Local Technical Implementation Unit (UPTD) of Propagation, South Sumatra Province in Ogan Komering Ulu (OKU) Timur Regency. Duku tree used was 15 years old with the height around 10 meter. Complete Randomized Design was used with 3 replications where duku trees as the replicates. The spraying consisted of 3 single plant growth regulator treatments and 6 mixed treatments which were P1 (BAP 300 mg.L-1), P2 (NAA 300 mg.L-1), P3 (GA3 300 mg.L-1), P4 (BAP 100 mg. L-1 + GA3 200 mg.L-1), P5 (BAP 200 mg.L-1 + GA3 100 mg.L-1), P6 (BAP 150 mg.L-1 + GA3 150 mg.L-1), P7 (NAA 100 mg.L-1 + GA3 200 mg.L-1), P8 (NAA 200 mg.L-1 + GA3 100 mg.L-1), P9 (NAA 150 mg.L-1 + GA3 150 mg.L-1). Spraying was applied twice with a half dosage for each application. First application was performed about one month after flowering, and the second was one and a half month after flowering. Data were analyzed using analysis of variance and least significance difference at α 5%. The measurement of parameters were carried after harvest or 3 months after treatment. Results showed that plant growth regulator positively affected duku fruit formation. GA3 treatment then was considered as the best treatment as it had a unison in fruit maturity, the highest number of fruit per bunch, weight per fruit and total fruit weight per bunch, and had the lowest number of green fruit and seed per fruit.

“…However, variation in fruit number and characteristics were found due to the variation of proper nutrient supply. Nkansha et al (2012) from a similar study found that the growth regulators (GA3 25 ppm and NAA 25 ppm) gave the best results in terms of increasing fruit set, number Amropali got significant differences in respect of quality character (%TSS). It was observed that Amropali is found to be the sweetest variety of mango having the TSS value higher than any other.…”

An experiment was conducted to investigate the effect of six pre-harvest treatments on yield, quality and shelf life of a particular Mango cv. Amropali under field condition. The experimental factors were Control, Decis and Savin @ 2 ml L . Boron treatment also extended the shelf life of mango as well. The maximum shelf life was found from large sized fruits. Similar performance on yield, quality and shelf life were obtained from Magic growth treatment @ 2 ml L -1 followed by pheromone trap treatment. Control treated fruits exhibited the minimum number of fruits per plant with lower quality but better TSS%. Smaller fruits were obtained from untreated control plants. Monira et al.

“…Maximum yield (44.80 kg per treatment) was recorded in case of 45 ppm closely followed by 60 ppm (44.60 kg). Also, Nkansha et al (2012) conducted an experiment to study the effect of plant growth regulators on fruit set and yield on Keitt mango trees in order to study the effect of Gibberellic acid (GA3) and Naphthalene Acetic Acid (NAA) sprays at different concentrations on fruit retention, fruit quality and yield. Trees were sprayed at full bloom stage.…”

“…Combined treatment of GA3 (20 ppm) + BA (10ppm), GA3 (10 ppm) + BA (5 ppm) and GA3 (10 ppm) + promalin (250 ppm) when applied as single spray at full bloom increased fruit set, fruit retention, yield efficiency and fruit quality (Sharma and Karan, 2008). Nkansha et al (2012) conducted an experiment to study the effect of plant growth regulators on fruit set and yield on "Keitt" mango trees in order to study the effect of GA3 and NAA sprays at different concentrations on fruit retention, fruit quality and yield. Trees were sprayed at full bloom stage.…”

This study was conducted during two successive seasons of 2016 and 2017 on Haied and Amal apricot cultivars trees (5 years old) grown at 5 x 4 meters apart in Sandy soil of a private orchard at Nobaria, Beheira governorate. The treatments including Hockley Alpha the commercial name of (Naphthyl acetic acid 45%, Naphthyl acetamide 1.20%) sprayed alone at 120 g / 200 L of water and Nano Bloom the commercial name of (Naphthyl acetic acid 2%, Naphsoxy acetic acid 3%,
