摘要

Combining fruit-based agroforestry systems with bulb crop cultivation, along with integrated nutrient management and mulching, provides a sustainable approach for developing nations to enhance productivity while preserving both soil quality and human health. This study assessed the influence of planting conditions, nutrient sources, and mulches on onion growth and yield within a wild pomegranate-based agroforestry system. This study was carried out at the experimental farm in Pandah, a facility of the Department of Silviculture and Agroforestry, Dr. YS Parmar University of Horticulture and Forestry, located in Nauni, Solan, India. The experiment was arranged in a randomized block design (RBD, 2-factorial) with three replications, consisting of 10 treatments. viz., T1: Absolute control, T2: FYM (N equivalence basis), T3: Goat manure (N equivalence basis), T4: RDF (Recommended dose of Fertilizer), T5: FYM + Pine mulch, T6: RDF + Pine mulch, T7: Goat manure + Pine mulch, T8: FYM + Broadleaf mulch, T9: RDF + Broad leaf mulch, T10 Goat manure + Broad leaf mulch. Treatment T9 (RDF + Broadleaf mulch) showed best results in the growth parameters and yield parameters like leaf length (53.05 cm), polar diameter (7.63 cm), equatorial diameter (7.10 cm), bulb weight (124.13 g), yield per hectare (177.35 q ha−1) of onion. Treatment T6 (FYM + broadleaf mulch) resulted in significant enhancements in soil quality. Additionally, soil parameters such as electrical conductivity (0.34 dSm−1), soil organic carbon (1.01%), available nitrogen (338.76 kg ha−1), available phosphorus (52.32 kg ha−1), and available potassium (331.98 kg ha−1) were found better under the wild pomegranate canopy compared to sole cropping. The highest gross returns (9305.43 US$ ha−1) and net returns (5995.74 US$ ha−1) and the highest benefit–cost ratio (2.81) was observed in treatment T9 (RDF + Broadleaf mulch) under wild pomegranate. This research highlights the potential of combining fruit trees with bulb crops, supported by proper nutrient management and mulching, to promote sustainable farming, increase farmer income, and enhance both soil and human health.
