Calagem e cama de frango influenciam o crescimento de Serjania erecta Radlk

Abstract

Serjania erecta Radlk (Five Leaf Vine, Sapindaceae) is used due to its medicinal properties, as anti-inflammatory, for stomach pain, ulcers and hypertension. As there is no record of cultivation of Cipó five leaves and considering that the use of plants in situ should be avoided or exploited sustainably, it is important to study cultural treatments aiming at their ex situ cultivation, such as addition of organic waste and correction of soil (limestone addition). Thus, the objective was to evaluate the growth and yield of Cipó five leaf plants grown with chicken litter and limestone. The experiment was carried out under 50% shading protected environment, and the evaluated factors were: chicken litter doses (0, 5, 10, 15 and 20 t ha -¹) combined with the use or not of limestone. The experimental arrangement was in a 5 x 2 factorial scheme, in a randomized block design with four replications. The experimental unit consisted of four pots, filled with 4.5 kg of substrate and one plant per pot. At each 30 DAT, plant heights, stem diameter, chlorophyll index were measured. At 120 DAT, leaf area was determined, as well as fresh and dried masses of leaves, stems and roots. The photochemical and biochemical characteristics were also evaluated. Plant height was influenced by the interaction between the factors under study, with the highest maximum height of 11.31 cm under 20 t ha-1 of chicken litter, with limestone. The highest chlorophyll index was 41.30, under 20 t ha-1 of chicken litter, regardless of the use of limestone. The largest leaf areas were 136.38 cm2 / plant and 213.05 cm2 / plant, with and without limestone, under 10 and 20 t ha-1, respectively. The largest fresh masses of leaves and roots were 6.27 g / plant and 5.17 g / plant, respectively, both with 20 t ha-1 chicken litter, without limestone. The largest leaf dry mass under 20 t ha-1 of chicken litter (1.15 g per plant) or without limestone (1.17 g per plant). The use of chicken litter at a dose of 20 t ha-1 resulted in better developed Serjania erecta seedlings, regardless of the use of limestone.
