Various growth regulators have been used to improve the quality of different fruit crops. Foliar spray of macro and micronutrients play an important role in vegetative growth, yield and fruit quality. In the present study, the influence of foliar application of growth regulators and nutrients on fruit splitting and fruit quality was evaluated. For that purpose, Naphthaleneacetic acid (NAA), Potassium nitrate (KNO3) and Boric acid (H3BO3) at the rate of 40 ppm, 1% and 0.3% were used respectively. Spray of chemicals were applied in 2nd and 8th week from full bloom to yield in pomegranate cultivar ‘Golden pearl’. The experiment was designed under Randomized Complete Block Design (RCBD) comprised with seven treatments and replicated thrice. Fruit splitting was reduced (48.68%) significantly with application of KNO3 + Boric acid, while maximum fruit size (60.26 cm2), fruit weight (84gm), fruit grain weight (136.38gm), total soluble solid (TSS) 12.52% and yield (21.9kg/plant) were observed in KNO3 + Boric acid. Moreover, peel weight was increased in control (60.66 gm) and minimum was observed in 48.62 gm in KNO3 + Boric acid. Finally, it is concluded KNO3 %+ Boric acid reveled best results against fruit splitting % and other fruit quality parameters. These findings show that application of KNO3+ Boric acid significantly influences fruit quality of pomegranate when fruit are in the beginning stages of growth and development.

Aim: To evaluate the efficacy of foliar application of Ascophyllum nodosum extract, homobrassinolide, and triacontanol for improving fruit retention, yield, and quality in mango. Methodology: The experiment was laid out in a randomized block design with 10 treatments, comprising Ascophyllum nodosum extract (1000, 3000, and 5000 ppm), homobrassinolide (0.1, 0.3, and 0.5 ppm), triacontanol (1, 3, and 5 ppm), and water as control. Treatments were foliar sprayed at panicle initiation, pea, and marble stages of fruit growth. Observations were recorded on flowering, fruiting, yield, and fruit quality parameters. Results: All the treatments of Ascophyllum nodosum extract and triacontanol exhibited significant improvement in fruit retention, fruit weight, yield, and fruit quality parameters over control. However, 3000 and 5000 ppm Ascophyllum nodosum extract treatments outperformed all the treatments of triacontanol. Plants sprayed with 5000 ppm Ascophyllum nodosum extract recorded the maximum value for fruit retention (48.15, 36.74, 29.48, and 25.76% at 3, 6, 9, and 12 weeks after pea stage, respectively), number of fruits (133.25 per tree), fruit weight (188.84 g per fruit), and yield (25.16 kg per tree), whereas the lowest values were recorded under control. With respect to fruit quality, 3000 ppm ANE produced the fruits with the highest TSS (19.62 °B), whereas the highest TSS/acid ratio was recorded with 5000 ppm ANE (62.29) treatment. Interpretation: In mango, foliar application of Ascophyllum nodosum extract (3000-5000 ppm) thrice at panicle initiation, pea, and marble stages of fruit growth is effective for reducing fruit drop and enhancing quantum and quality of produce.

The role of arbuscular mycorrhizal fungi in sweet oranges is well known, but the function of their secondary metabolite, especially the easily extractable glomalin-related soil protein (EE-GRSP), an active fraction of glomalin, is still unclear. The proposed study aimed to analyze the field response of foliar application of exogenous EE-GRSP on tree mycorrhizal development and fruit quality of two sweet orange (Citrus sinensis L. Osbeck) varieties viz., Lane Late Navel (LLN) and Rohde Red Valencia (RRV). Application of EE-GRSP significantly increased the root mycorrhizal colonization and soil mycorrhizal hyphal length in both the sweet orange varieties. The external quality of fruits (fruit weight, polar diameter, and equatorial diameter) also improved in response to foliar application of EE-GRSP in both sweet orange varieties. However, EE-GRSP treatment showed no change in fruit soluble solid content, while it increased the Vc content, solids-acid ratio, fructose, glucose, and sucrose content of sarcocarp in the two sweet oranges varieties. The LLN variety treated with EE-GRSP recorded significantly higher N, P, K, Fe, and Si content of sarcocarp as a mark of nutritional quality, while the RRV variety treated with EE-GRSP displayed a higher concentration of nutrients like Cu, Fe, Si, and Zn in the sarcocarp as compared with the corresponding non-treated control. To the best of our knowledge, this is the first report regarding the improvement in fruit quality of late-ripening sweet oranges (especially LLN) in response to foliar application of EE-GRSP as another potential biostimulant.

The experiment was conducted at the Agronomy Field Laboratory, Bangladesh Agricultural University, Mymensingh, to explore the growth and yield performance of boro rice cv. BRRI dhan28 is influenced by foliar spray of potassium nitrate (KNO3) at four rice growth stages. The experiment consisted of four doses of KNO3 viz. 0 (Control), 0.25, 0.50 and 1.00 kg ha−1 and applied at four growth stages of rice development viz. at panicle initiation, at ear emergence, at anthesis period and at dough stage. This experiment was carried out in Randomized Complete Block Design (RCBD) with three replications with 10 m2 (4.0 m × 2.5 m) unit plot size and spacing between blocks and unit plots was 1 m and 0.5 m, respectively. Results revealed that foliar application of potassium nitrate at four growth stages significantly affected yield and yield contributing characters of BRRI dhan28. But most of the yield contributing characters did not differ significantly due to the interaction between potassium nitrate and stage of foliar spray. However, the foliar application of KNO3 @ 0.25 kg ha−1 showed the highest yield production (5.86 kg ha−1) while the lowest yield (4.85 kg ha−1) was found in control. Furthermore, better yield performances were recorded when the KNO3 was applied at panicle initiation stage rather than the other four growth stages. The total number of tillers, 1000–grain weight and grain yield, was higher with foliar spraying of a 0.25 kg ha−1 KNO3 at panicle initiation stage. From this experiment, it may be concluded that foliar application of KNO3 affected the yield performances of BRRI dhan28 and 0.25 kg ha−1 KNO3 produced the highest grain yield when applied at panicle initiation stage of boro rice.

The present study was carried out during the seasons of 2014 and 2015 at the Research and Agricultural Experimental Station, King Saud University, Saudi Arabia, to investigate the effects of foliar application of CaCl2 at 1 or 2%, Ca(NO3)2 at 0.5 or 1% and ascorbic acid at 50 or 100 ppm on yield and fruit quality of Ziziphus jujuba trees. All treatments were repeated twice (December 15 and January 15) before harvest date in both seasons. Treatments significantly improved yield and fruit physical characteristics (fruit weight, flesh weight, fruit volume, fruit length, fruit diameter and fruit firmness) in comparison to untreated control in both seasons. Fruit chemical characteristics (TSS, Acidity, total sugar contents, ascorbic acid, and total chlorophyll) were mostly improved by most tested treatments in both seasons over the control (water only). It can be concluded that foliar application with Ca(NO3)2 at 1% would be the best treatment to obtain highest yield, fruit physical and chemical composition of Z. jujuba.

Aims: To study the effect of different micronutrients and number of foliar spray on fruit quality and leaf nutrient content of peach. Study Design: The experiment comprised of seven treatments and conducted on seven years old plants in Randomized Block Design with three replications. Place and Duration of Study: The experiment was conducted at the experimental orchard of Department of Horticulture, CCS Haryana Agricultural University, Hisar during the year 2018. Methodology: The treatments included in the study consisted of three micro-nutrients [T1- ZnSO4 @ 0.2%, T2- ZnSO4 @ 0.3%, T3- FeSO4 @ 0.2%, T4- FeSO4 @ 0.3%, T5- Boric acid @ 0.1%, T6- Boric acid @ 0.2%, T7- Control (water spray)] each applied as foliar spray at different concentration as single and double spray. Results: The results showed that foliar spray of micronutrients significantly improved quality and leaf nutrient status in peach cv. Shan-e-Punjab. The foliar spray of FeSO4 @ 0.2% (T3) found to be the best treatment with respect to TSS (11.06%), ascorbic acid (8.18 mg/100 g pulp) and leaf iron content (345.51 ppm). The highest TSS: ratio (23.88), leaf zinc content (35.42 ppm) and lowest acidic fruits (0.45%) was observed from the plants sprayed with T1 (ZnSO4 @ 0.2%), whereas, highest leaf boron content (91.02 ppm) was recorded with T6 (Boric acid @ 0.2%). Double foliar spray of micronutrients (Fe, Zn and B) at first week of March + April significantly TSS, TSS: acidity, ascorbic acid, leaf zinc, iron, and boron content and reduced acidity fruits then single foliar spray in first week of March. Conclusion: The foliar spray of ZnSO4 @ 0.2% (T1) proved to be best treatment in terms of quality. A double spray of micronutrients (Fe, Zn and B) significantly increased total soluble solids, TSS: acidity, ascorbic acid, leaf (zinc, iron, and boron) content and reduced fruit acidity as compared to single spray.
