“…Dentre os biofertilizantes, o bokashi é uma mistura balanceada de resíduos de origem vegetal e/ou animal, submetida ao processo de fermentação controlada por microorganismos benéficos (LIMA et al, 2015), considerado inoculante biológico orgânico, disponibilizando nutrientes durante o ciclo de cultivo, isto é, podendo favorecer a brotação de estacas de pimenteira rosa.…”

Schinus terebinthifolius Raddi. (pimenteira rosa, Anacardiaceae) é utilizada devido às suas propriedades medicinais e condimentares, com valor agregado no mercado. Apesar disso, há poucos estudos relacionados à propagação vegetativa e custos de produção de mudas da espécie. O objetivo deste trabalho foi avaliar a presença de folhas e uso de bokashi na propagação vegetativa da pimenteira rosa. Avaliaram-se três tipos de estacas caulinares com 0, 1 ou 2 folhas, sem e com adição de bokashi (10 g kg-1) ao substrato, sob sombrite 50%. O arranjo experimental foi em esquema fatorial 3x2, no delineamento de blocos casualizados, com quatro repetições. As maiores porcentagens de brotações foram observadas em estacas sem folhas, sem bokashi (50,0%), aos 35 e 42 dias após o estaqueamento (49,3% e 47,2%, respectivamente); o maior índice de velocidade de brotação foi nas estacas sem folhas (0,5766) e o maior comprimento de brotos (24,37 cm) foi observado com a adição de bokashi ao substrato. Os custos de produção variaram entre R$ 232,07, entre o maior (R$ 2.428,66) com bokashi e o menor (R$ 2.196,59), sem bokashi. A quantidade de folhas e uso de bokashi influenciaram na propagação por estaquia e custos na produção de mudas de pimenteira rosa.

The Inceptisol of Karangploso Malang has low pH (5.33) and low C-organic content (1.39%). Efforts can be made to improve these problems through land management with the use of organic fertilizer. Bokashi is one of the composts produced from fermentation process with EM4 which can improve soil chemical properties, because bokashi has elements of N, P, K, Na, Ca, and Mg respectively 1.22%, 0.53%, 1.71%, 5.64%, 0.62% and 2.01%. This study was carried out at the Greenhouse and Chemical Laboratory of Soil Science Department, Agriculture Faculty, Brawijaya University. The design of this research was a completely randomized design with O0 treatment (control); O1 (Bokashi 5 t ha -1 ); O2 (Bokashi 10 t ha -1 ); O3 (Bokashi 15 t ha -1 ); O4 (Bokashi 20 t ha -1 ); O5 (Bokashi 25 t ha -1 ); O6 (Bokashi 30 t ha -1 ) which was repeated 3 times. Parameters measured were pH, CEC, BS, K-exch, Na-exch, Ca-exch, and Mg-exch on 1 MAI (month after incubation), and 2 MAI. The results showed that increasing the dose of bokashi application at 1 MAI significantly increased K-exch and Mg-exch compared to the control treatment, but did not significantly affect pH, CEC, BS, Na-exch, and Ca-exch. Furthermore, increasing the dose of bokashi application on 2 MAI significantly increased pH and K-exch compared to the control treatment, but did not significantly affect CEC, BS, Na-exch, Ca-exch, and Mg-exch.

“…The PCA allows detection of anomalous samples, relationships among variables, and groups of samples with similar properties (Lyra et al, 2010). In soil science, PCA has been used in studies on chemical and physical properties that affect crop yield (Santi et al, 2012), on pedological relationships that aid soil classification (Gomes et al, 2004;Valladares et al, 2008), and on the effects of adoption of conservation practices on soil properties (Santos et al, 2008;Lima et al, 2015).…”

ABSTRACT:The intensive nature of soil use in vegetable production areas has led to a marked decrease in soil quality. The objective of this study was to evaluate the effects of adoption of soil management systems on vegetable production with regards to the chemical properties of a Rhodic Ferralsol after five years and to evaluate the use of the Principal Component Analysis (PCA) statistical tool in discriminating the different treatments. The experiment was conducted under field conditions in central Brazil in a randomized block design with four replications and a 3 × 2 factorial arrangement (three soil management systems × two cover crops). The soil management systems used were NT (no-tillage), RT (reduced tillage), and CT (conventional tillage). The cover crops used were corn (Zea mays) alone and corn intercropped with the gray velvet bean (Stizolobium niveum). Reduced tillage showed the highest values of sum of bases, cation exchange capacity (T), and total organic carbon contents in the 0.00-0.05 m layer. In the same layer, RT and CT showed higher values of pH and K content. No-tillage and RT showed the highest P and Ca 2+ contents and H+Al and T values. In the 0.05-0.10 m layer, RT had higher a pH value and Mg 2+ contents. No-tillage and CT had higher potential acidity in this layer. The management systems (0.10-0.30 m) and the cover plants (all layers) had no effect on the properties analyzed. The use of PCA determined that the two principal components explained the following percentage of the data variance: 90.8 % (0.0-0.05 m), 79.8 % (0.05-0.10 m), and 83.1 % (0.10-0.30 m). Analysis of the eigenvectors and the grouping of treatments in PCA also showed that RT was most effective in improving soil fertility properties. Reduced tillage was most effective in increasing soil fertility after five years. The PCA is recommended as a useful tool and it allowed the identification of patterns not revealed by traditional tools.
