Globally speaking, optimizing the use of organic fertilizers plays a significant role in sustainable agriculture and is essential for enhancing crop productivity and improving soil health, while organic fertilizers are also easily available at a low cost. This study specifically aimed to determine the influence of organic fertilizer incorporation (high and medium levels) practices versus chemical fertilization with urea on the crop yields and quality of zapallo tetsukabuto. This included a control treatment without fertilization. Agronomic quality was evaluated by measuring the main performance parameters of the hybrid zapallo tetsukabuto (Cucurbita maxima x Cucurbita moschata): REND yield (in kg) of the total fruit per plant per plot; NFRC, number of commercial fruit per plant per plot; NFRT, total number of fruit per plant per plot, grown following the production guidelines of the area. The research findings show that the yields with organic fertilizer with the highest dose of the compost incorporation treatments increased 30% compared to the unfertilized control, but with no significant differences to the urea-fertilized treatment (1%) for zapallo. That is, performance parameters were similar in the zapallo crop fertilized with compost and with urea. These trials demonstrate that compost is a sustainable alternative and an adequate source of nutrients for zapallo cultivation.

有机施肥提高了 zapallo tetsukabuto 的作物产量和质量


从全球来看，优化有机肥料的使用在可持续农业中发挥着重要作用，对于提高作物生产力和改善土壤健康至关重要，同时有机肥料也很容易以低成本获得。本研究专门旨在确定有机肥掺入（高水平和中水平）做法与尿素化学施肥对 zapallo tetsukabuto 作物产量和质量的影响。这包括不施肥的对照处理。通过测量杂交 zapallo tetsukabuto（Cucurbita maxima x Cucurbita moschata）的主要性能参数来评估农艺质量：每地每株植物总果实的 REND 产量（以公斤为单位）;NFRC， 每块地每株植物的商业果实数量;NFRT，每块地每株植物的果实总数，按照该地区的生产指南种植。研究结果表明，与未施肥的对照相比，使用最高剂量堆肥掺入处理的有机肥的产量增加了 30%，但与 zapallo 的尿素施肥处理 （1%） 没有显着差异。也就是说，用堆肥和尿素施肥的 zapallo 作物的性能参数相似。这些试验表明，堆肥是一种可持续的替代品，也是 zapallo 种植的适当营养来源。
