Uso de esterco bovino em diferentes doses para o crescimento do coentro (Coriandrum sativum L.)

Abstract

Coriander (Coriandrum sativum L) belongs to the Apiaceae family and is widely used as a seasoning, being a widely consumed vegetable in several regions of Brazil. The cultivation of this crop has great socioeconomic importance for family farming, especially in the northern region of the country, where its commercialization guarantees an economic return for small producers. This study aimed to evaluate the growth of coriander under increasing doses of cattle manure. The experiment was conducted in a controlled environment, in the greenhouse of the Juruti University Campus of the Federal University of Western Pará UFOPA, in the city of Juruti (PA), in a completely randomized design (CRD). Coriander seeds were grown in pots with different doses of cattle manure (g), treatments T1 = control; T2 = 10; T3 = 20; T4 = 30 and T5 = 40, where the manure doses have an equivalence of 2.0; 4.0; 6.0 and 8.0 Mg ha-1 respectively. Variables such as plant height (PH), number of leaves (N°L), fresh leaf mass (FLM), leaf dry mass (LDM), root fresh mass (RFM), root dry mass (RDM) were analyzed, root length (RL). After data collection, they were subjected to the assumptions of analysis of variance and once met, the variables were subjected to analysis of variance (F test p ≤ 0.05). And when significant, the quantitative variables or doses adjusted to linear models, through regression analysis. The estimation of model parameters, residual analysis, and verification of the quality of fit (R2) were carried out using the SISVAR statistical program. The results indicated higher doses of cattle manure, such as T4 (30g) and T5 (40g), showed greater growth and productivity of coriander compared to treatments with lower proportions and the control. This demonstrates that cattle manure enriches the soil with essential nutrients, improving its physical and biological conditions.
