Impact of Plant Vitalizer on the flowering, chemical and economic attributes of Mango

Excessive use of chemical fertilizers in mango ( Mangifera indica ) cultivation has led to serious threats to soil health and environmental sustainability. To address these concerns, the present study was undertaken to explore eco-friendly alternatives using organic bioenhancers, applied individually and in combination with paddy straw mulch. The objective was to assess their potential in improving the nutrient status and leaf biochemical characteristics of mango trees, thereby promoting sustainable production practices. The experiment was conducted during 2024–2025 at the Department of Agriculture, Mata Gujri College, Fatehgarh Sahib, Punjab, India (30°37′7.17″N, 76°24′28.14″E), following a factorial randomized block design comprising ten treatments. Findings revealed that the combined application of 3% Dasgavya and paddy straw mulch significantly enhanced the biochemical and nutrient parameters of mango trees. This treatment recorded the maximum leaf area (86.02 cm²), leaf area index (0.03), number of inflorescences per branch (7.53), fruit retention (50.92%), specific gravity (1.01 kg/m³), and non-reducing sugar content (3.84%). The results clearly indicate that integrating organic bioenhancers with paddy straw mulch can serve as a sustainable and effective substitute for chemical fertilizers, improving both plant health and environmental quality.
