Effect of field pea (Pisum sativum subsp. arvense (L.) Asch.) and pea-oat (Avena sativa L.) biculture cover crops on high tunnel vegetable under organic production system

Abstract In general, adaptation of cover cropping in crop rotation practices to organic tunnels by methods supporting soil health and quality has not yet been fully optimized. Effect field pea pea-oat crops physicochemical properties cash was assessed an high tunnel southern Poland 2016–2017, with the following planting sequence: spring crops/tomato/romaine lettuce/green bean/iceberg lettuce. The sole produced a lower aboveground biomass (3.06 t ha −1 ) than mixture (4.17 ), N content their 155 kg 136 , respectively. results indicated that residue input from important for carbon stock, retaining plant-available matter, improving physical properties, especially wet aggregate stability. We observed increase pH availability some mineral nutrients under treatments, Ca, Mg, K, P. uptake subsequent significantly ( p ≤ 0.05) increased biculture, green manure formula mulch treatment. Early depressed tomato yield, but enhanced bean yield second year cropping.
