“…The above findings are supported by Gurung et al (2016) in mandarin.The increase in the sugar content might be due to the more rapid translocation of sugars from leaves to developing fruits. Boron facilitated sugar transport within the plant.…”

Being one of the finest fruit, litchi still need a major attention toward the problems like irregular flowering, poor fruit set, heavy fruit drop, low yield, fruit cracking and poor quality to meet the growing demand of national and international market. Bio-regulators and micro-nutrient are being used by the growers to increase the yield by improving the yield attributing parameters. The present experiment was laid out at the

“…These results were coincide with those obtained by Dawoodet al 2000 Gurung et al (2016). They concluded that foliar spraying of micronutrients (boron and zinc) increased the yield and the combined spraying of them was most effective in improving the fruit yield / tree in citrus and other fruit crops.…”

Also, Khan et al (2012) and Baghdady et al (2014) indicated that foliar spraying with Chelated zinc and boron significantly increased fruit quality in orange and madarin fruits.…”

The present study was carried out during two successive seasons 2015 and 2016 on of Valencia orange trees (Citrus sinensis L. Osbeck) budded on Volkamer lemon (Citrus volkameriana L.) rootstock, grown in sandy soil under drip irrigation system, in a citrus orchard located in El-Kwamel farm, college of Agriculture, Sohag University, Egypt. The selected trees (33 tree) of Valencia orange cv. were set as a randomized complete block design (RCBD) with 3 replications. The target of this study was to investigate the effect of foliar spraying of multi-micronutrients (1% B, 200 ppm Zn and 250 ppm Fe) and three levels of putruscine (10-3, 10-5 and 10-7mM/Lit) individually or their combinations at full bloom and after ten days from fruit set on productivity and some quality parameters upon harvest as well as during storage at room (ambient) temperature for better marketability of Valencia orange without economical loss. It can be concluded that 10-3mM/Lit (PUT) + Multi-micronutrients treatment gave the highest values of fruit set, retained fruit/tree, fruit weight (g), fruit juice weight (g), fruit juice volume (cm) and fruit peel thickness (mm) of Valencia orange. As well as it gave the highest rate of total soluble solids (TSS) percentage, TSS/acid ratio and ascorbic acid (100g juice) and the lowest values of fruit decay percentage during storage period. This study suggested that 10-3mM/Lit (PUT) + Multi-micronutrients treatment may be consider a useful technology for improve productivity and some quality parameters upon harvest of Valencia orange trees. As well as, the same treatments to avoid the negative quality effects during fruit storage at room (ambient) temperature especially increase the rate of total soluble solids percentage, TSS/acid ratio and ascorbic acid (100g juice) for better marketability of Valencia orange fruits without economical loss.

“…The increased TSS due to the spray of nutrients combination might be due to the increased photosynthesis activity [25], translocation of sugars from source to sink and conversion of complex form of sugars (polysaccharides) to simple sugars (glucose and fructose) in fruits [21] due to the increased activities of enzymes by zinc and potassium. The results of present study are supported by the findings of investigators who reported the highest total soluble solids in Kinnow mandarin with foliar application of GA 3 15 ppm along with zinc 0.5% and boron 0.1% [26]. Researchers stated that Kinnow mandarin fruits had the highest total soluble solids with foliar application of Zn + B on plants [27].…”

Aims: To determine the suitable combination of fertilizers for obtaining high quality fruits from Kinnow orchard. Study Design: The experiment was conducted in randomized block design with three replications per treatment on Kinnow mandarin. Place and Duration of Study: The experiment was conducted on seven years old earmarked plants at Experimental Orchard and in Post-harvest Technology Laboratory of the Department of Horticulture, CCS Haryana Agricultural University, Hisar, Haryana, India during the year 2016-17. Methodology: The treatments comprising of 11 combinations of Urea, K2SO4, ZnSO4, FeSO4 and boric acid which were laid out in randomized block design with three replications. Seven years old uniformly grown trees spaced at 6x6 m were selected for the present study and analyzed for yield and quality parameters such astotal soluble solids (%), acidity (%), ascorbic acid (mg/100 ml juice), juice content (%), TSS to acid ratio etc. Results: In comparison to other fertilizers combinations, the maximum fruit yield per plant (97.83 kg/plant), juice content (49.47%), total soluble solids (9.80%), TSS to acid ratio (11.95) and ascorbic acid content (32.30mg/100ml) and minimum acidity (0.83%), rag (24.00%) and peel content (25.60%) and peel thickness (3.42 mm) were registered with foliar application of Urea 1.0% + K2SO4 1.0% + ZnSO4 0.5% + FeSO4 0.5% + H3BO3 0.2%, however, the foliar spray of Urea, K2SO4, ZnSO4, FeSO4 and boric acid had no effect on number of seeds per fruit in Kinnow mandarin. Thus it is clear from results that foliar nutrient application showed a stimulating influence on yield and quality parameters of Kinnow fruits. Conclusion: From the research findings it can be concluded that the maximum potential of Kinnow mandarin plants in respect of fruit yield per plant, juice content, total soluble solids, TSS to acid ratio and ascorbic acid content was exploited to a maximum level and the acidity, rag and peel content and peel thickness to a minimum level with foliar application of Urea 1.0% + K2SO4 1.0% + ZnSO4 0.5% + FeSO4 0.5% + H3BO3 0.2%.
