Effect of phosphorous in combination with biofertilizers on growth, yield and quality of strawberry cv. Winter Dawn

Abstract

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.

Biofertilization with PGP Bacteria Improve Strawberry Plant Performance under Sub-Optimum Phosphorus Fertilization

“…However, biofertilization with the designed PGPB consortium damped the presence of these signs of nutritional stress and, overall, had a positive effect on strawberry plants, in terms of growth, physiological performance, and nutritional balance under phosphorus fertilization withholding. This response would confirm the potential of this biofertilization process to improve the efficiency of strawberry fertilization practices, as has previously been described in other crops, including strawberry [11,45,46].…”

“…Intensive work has been done to get to know the most adequate management of strawberry crop fertilization. Therefore, the studies have focused on: the influence of different doses of industrial fertilizers on vegetative development and strawberry yield [6,7], the effect of chemical and organic fertilizers [7,8], the use of organic fertilizers as opposed to chemical fertilizers before planting and during the development of the crop [9,10], and the combination of chemical and biofertilizers [11,12]. However, despite this progress, strawberry cultivation still uses a large number of agrochemicals, which contribute to maintaining high production levels but entail high economic costs for producers, not to mention the aforementioned obvious environmental risk.…”

Micronutrient and Metabolic Profiling of Strawberry Cultivars Grown in Subtropical Conditions: A Review

“…All growth characters like maximum plant height with 120% dose of P per plant and maximum plant spread, number of leaves per plant and minimum no. of days taken to first initiation of flower observed with RDP 100%, but with increased P rates (120%), these growth characters decreased (Reddy et al, 2021). The continual application of water soluble phosphatic fertilizer together with the prescribed doses of nitrogen and potassium may have contributed to these findings by enhancing nutritional absorption in strawberry fruits (Ahmad et al, 2018;Singh et al, 2019).…”
