Abstract

The objective of this research was to evaluate the effect of two organic fertilizers used before planting and in top dressing in the production of parsley. Seven treatments were evaluated, resulted from the factorial 2 x 3 + 1: two organic fertilizers (castor bean cake, and hoof and horn powder) x 3 modes of application (100% before planting; 100% in top dressing; 50% before planting and 50% in top dressing) + 1 control. The experimental design was in randomized blocks, with five replications and plots of 1 m2. Two harvests were done and in both the following characteristics were evaluated: the relative chlorophyll index ("Spad''), plant height, fresh (FW) and dry (DW) matter weight of shoot and macronutrients accumulation. There was no significant difference for the ‘’Spad” index in both harvests. For the other characteristics, the control was inferior to the other treatments. In the comparison among application modes, the treatment with castor bean cake, 100% before planting, was inferior to the other applications modes of this fertilizer for FW and DW. For hoof and horn powder, the 100% in top dressing application mode was superior to other applications. In the comparison between fertilizers, the hoof and horn powder was superior to castor bean cake in both harvests when application was done 100% before planting. The descending order of macronutrients accumulation was: K > N > Ca > P > Mg. Therefore, it is recommended to apply hoof and horn powder, 100% in top dressing application.

欧芹生产在种植前和追肥中施用有机肥

本研究的目的是评价两种有机肥在欧芹种植前和追肥中施用的效果。根据2 × 3 + 1的因子，对7种处理进行了评价:两种有机肥(蓖麻豆饼和蹄角粉)× 3种施用方式(种植前100%;100%面肥;种植前50%，追肥50%)+ 1对照。试验设计采用随机分组，5个重复，样地面积为1 m2。在两次采收中，分别对叶绿素相对指数(Spad)、株高、茎部鲜(FW)和干(DW)物质质量及大量养分积累量进行了评价。两季“Spad”指数无显著差异。在其他性状上，对照不如其他处理。在不同施用方式的比较中，种苗前100%投投蓖麻豆饼处理的肥力低于其他施用方式。对于蹄角粉，追肥100%施用方式优于其他施用方式。在肥料对比中，种苗前施用100%时，两次收获马蹄角粉均优于蓖麻饼。宏量营养素积累量的递减顺序为:K >N比;Ca比;P比;毫克。因此，建议在追肥中使用100%的蹄角粉。
