Onion response to late-season water stress at two plant populations. Split onion bulbs is a phenomenon where the bottom of the bulb splits open. Split bulbs can reduce onion crop marketable yields. Anecdotal evidence suggests that late-season irrigation interruptions c... ... Repositório: BDPA Ano de publicação: 2014
Onion response to irrigation criteria for two varieties at two plant populations. Past research at the Malheur Experiment Station demonstrated the sensitivity of onion yield and grade to soil water tension (SWT) (Shock et al. 2000). The ideal SWT for initiating irrigations for drip... ... Repositório: BDPA Ano de publicação: 2014
Onion response to phosphorus application strategies and in-season nutrient supplementation.
