She watched the harvesting and apple picking.
Literal
She [topic-は] harvesting [and-や] apple-picking [object-を] watched.
取り入れ (harvest/harvesting) and りんごつみ (apple picking) are compound nouns for agricultural activities. 取り入れ comes from 取り入れる (to harvest, to bring in). りんごつみ = りんご (apple) + 摘み (picking). The を with みました (polite past of 見る) means she observed or watched these activities. The polite ました suggests this is spoken or written for a general audience.
