Abstract

The aim of this study was to evaluate the effect of different forms of application (before planting and as top dressing) of organic fertilizers, namely castor bean cake and hoof and horn powder, on the production of jambu plants. The experiments were conducted at the Experimental Farm of São Manuel, SP, and at the 'Estância Três Nascentes' site in Botucatu, SP. Seven treatments were evaluated in a 2 x 3 + 1 factorial design, with two organic fertilizers, castor bean cake (CBC) and hoof and horn powder (HHP), and three forms of application (100% before planting, 100% as top dressing, and 50% before planting + 50% as top dressing), plus a control treatment. The experimental design was a randomized complete block with four replications. Plant height, number of inflorescences (NI), fresh weight of inflorescences (FWI), fresh weight of vegetative parts (FWVP), and total fresh weight (TFW) were evaluated at each location. In São Manuel, there was a difference between fertilizers in the forms of application, 100% before planting and 50% before planting + 50% as top dressing, for FWVP and for TFW only in the first form. In Botucatu, HHP resulted in higher NI when applied 100% before planting and FWVP and TFW between fertilizers when applied 100% as top dressing. The increases compared to the control, with HHP and CBC, were 81%, 83%, 168%, 83%, and 95% in São Manuel and 19%, 42%, 316%, 56%, and 67%, in Botucatu, for plant height, NI, FWI, FWVP, and TFW, respectively, confirming the importance of supplementing base fertilization with organic compounds.

Jambu生产(Acmella oleracea) [(L.)R. K. Jansen])在种植和追肥时使用不同的有机肥

本试验旨在评价有机肥蓖麻豆饼和蹄角粉不同施用方式(种植前和追肥)对jambu植株生产的影响。试验在SP o Manuel试验农场和SP波图卡图' est ncia Três Nascentes'试验场进行。采用2 × 3 + 1因子设计对7种处理进行评价，采用两种有机肥，蓖麻豆饼(CBC)和蹄角粉(HHP)，三种施用方式(种植前100%，100%追肥，种植前50% + 50%追肥)，加上对照处理。实验设计为随机完全区组，共4个重复。测定植株高度、花序数(NI)、花序鲜重(FWI)、营养部分鲜重(FWVP)和总鲜重(TFW)。在s o Manuel中，种前100%和种前50% + 50%追肥的施用形式存在差异，FWVP和TFW仅在第一种形式下施用。在Botucatu，在种植前施用100%的HHP可获得更高的NI，在肥料间施用100%追肥可获得更高的FWVP和TFW。与对照相比，施用HHP和CBC后，曼努尔岛的株高、NI、FWI、FWVP和TFW分别增加了81%、83%、168%、83%和95%，而在波图卡图，则分别增加了19%、42%、316%、56%和67%，证实了施用有机肥的重要性。
