The article presents data on the study of the effect of foliar water-soluble mineral fertilizer NOVATEK Solub K-Max 10-5-30 on the biochemical composition and commercial quality of apple fruits. A rise in vitamin C from the introduction of NOVATEK at a rate of 2.5 kg/ha indicates the effectiveness of this drug for optimizing the content of ascorbic acid in fruits. An increase in the content of monosaccharides and a decrease in disaccharides were found for all the studied rates of consumption of agrochemicals. The use of mineral fertilizer “Novatek Solub K-Max” contributed to increase the dry weight of fruits. The application of this mineral fertilizer is recommended for inclusion in the industry regulations for Apple cultivation as one of the elements of the technology.

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.

The goal of this study was to examine how to improve the vegetative growth, nutritional status, productivity, and fruit quality of Washington navel orange trees by examining the effect of foliar application of ZnSO4 (0, 300, and 600 mg/L) solutions in combination with CuSO4 (0, 200, and 400 mg/L) solutions on Washington navel orange trees, which were 11 years old and grown in clay loam soil with a surface irrigation system. The results showed that all the investigated measurements responded specifically to each investigated factor. ZnSO4 elicited a stronger and more effective response than CuSO4. Nonetheless, the response varied only slightly or moderately from one measurement to the next. In terms of the interaction effect between ZnSO4 and CuSO4 concentrations, the effect of each investigated factor was directly reflected in its combinations, with ZnSO4 (600 mg/L) and CuSO4 (200 and 400 mg/L) being the most effective for the majority of the measurements under consideration. When the highest level of ZnSO4 was combined with the highest level of CuSO4, the highest values for the various vegetative growth parameters shoot length and diameter, number of leaves per shoot, leaf area, and total assimilation area per shoot were obtained. As a result, the nutritional status (the highest total leaf chlorophyll and leaf mineral contents) was significantly coupled with the treatment of 600 mg/L ZnSO4 in combination with 400 mg/L CuSO4. Moreover, the combinations of the highest ZnSO4 concentration (600 mg/L) and CuSO4 concentration (400 mg/L) exhibited the greatest statistical values of the measurements of fruiting aspects as well as fruit quality. Consequently, it can be recommended that using 600 mg/L ZnSO4 in combination with 400 mg/L CuSO4 as a foliar spray on monthly basis during the period from March to July could be safely recommended under similar environmental conditions and horticulture practices adopted in the present experiment.

In view of the importance of foliar application of macro and micro nutrients to increase the yield and quality of guava under high density planting system, an experiment was laid out in a randomized complete block design consisting of nine treatment combinations with three replications. [(Control - Fertigation alone), (NPK (19:19:19)), (NPK + Zn), (NPK + Ca), (NPK + B), (NPK + Zn + Ca), (NPK + Zn + B), (NPK + Ca + B), (NPK + Zn + Ca + B). Among the treatments, fruit weight (225.22 g), fruit volume (215.35 ml),number of fruits per plant (80.35), fruit yield per plant(17.67 kg plant-1), TSS(10.60 0Brix), titratable acidity (0.196 %) and pectin content (1.31 %) was found to be significantly higher with the foliar application of NPK @ 1% + Zn @ 0.5 % + B @ 0.4%. The foliar spray of NPK @ 1% + Ca@ 0.2% + B@ 0.4% significantly increased the fruit diameter (7.85 cm), and ascorbic acid content (159.84 mg 100g-1). Thus, foliar spray of NPK, zinc and boron maintained more number of fruits per plant and improved the fruit set leading to an 18% increase in yield. Whereas, the addition of calcium to the plants increased the ascorbic acid content of the fruit and pectin that enhanced the shelf life of the fruit

Aim: This study was carried out to investigate the effect of biofertilizers in combination with phosphorus rates on growth, yield and quality of strawberry. Methodology: The experiment was conducted during the year 2017-18 and 2018-19 at hi-tech greenhouse of the Department of Horticulture, CCS Haryana Agricultural University, Hisar. The experiment was arranged in a factorial completely randomized design with four phosphorus fertilizer rates (0, 80, 100 and 120% RDP per plant) and three biofertilizers (control, VAM and PSB) at five replicates. Growth and yield parameter were estimated. Quality traits, viz., TSS, acidity, ascorbic acid, anthocyanin and juice content of fruits were also measured at maturity stages. Results: All the possible combinations of phosphorous and biofertilizers were found to have significant influence on the vegetative growth, yield and quality parameters of strawberry. The minimum number of days taken to first flowering, maximum fruit weight, size and fruit yield per plant were recorded with 100% RDP along with VAM. TSS and ascorbic acid were noted maximum with combined application of 120% RDP and biofertilizers. Interpretation: VAM and PSB inoculation in combination with 100 percent recommended dose of phosphorous showed maximum vegetative growth, yield and quality of strawberry as compared to non-biofertilizer inoculation.
