Abstract

O objetivo desta investigação é determinar o papel do corte ortotrópico de ramos no crescimento das plantas de café arábica. Esta investigação foi realizada na aldeia de Ponilala, subdistrito de Ermera, Município de Ermera, de 2 de Fevereiro a 2 de Julho de 2016, com uma altitude de 750-1200 m acima do nível do mar (nm). O delineamento utilizado nesta investigação foi o Delineamento Completamente Casualizado (DIC), fatorial 3x3 que foi repetido em 3 blocos. O primeiro fator é o ramo do segmento ortotrópico (CRO), que é constituído por três níveis, ou seja, o segundo ramo do segmento (CRK2), Ramificação do Terceiro Segmento (CRK3), Ramificação do Quarto Segmento (CRK4), enquanto o segundo fator é a Forma de Corte (BP), que consiste em três níveis, nomeadamente a Forma de Corte Oblíqua (BPM), a Forma de Corte Cónico (BPL), Forma Corte plano (BPD). Os resultados da investigação mostraram que de um modo geral houve diferenças significativas nos fatores de segmentos de ramos nas variáveis observadas de altura de planta, número de folhas, área foliar e diâmetro do caule. Onde o maior no tratamento CRK2 foi o número de folhas com um valor de 10,4 cm, diâmetro do caule com um valor de 2,4 mm, área foliar com maior rendimento, nomeadamente 40,22 m2. No entanto, os melhores resultados percentuais de crescimento foram na combinação de tratamento CRK2BPM, nomeadamente 100% e os mais baixos foram obtidos na combinação de tratamento CRK3BPD, nomeadamente 50% de percentagem de crescimento

Abstract

The objectives to be achieved in this study are to determine the perception and attitude of students towards the benefits of urban forests in Talimoro Village. The variables observed in this study were student’s perceptions and attitudes towards the benefits of urban forests. The determination of the sample carried out was 3 faculties and 10 departments getting 10 respondents so that the total number was 100 respondents. The data collection method was carried out by taking secondary data and direct observation in the field. The collected data were analysed using the SPSS application to determine the frequency of students' perceptions and attitudes. The results showed that East Timor Coffee Institute students had a Very Good perception, with a score of 447 and statements regarding personal experiences from 100 respondents had a very good attitude with a score of 388.

Abstract

This study aimed to investigate the influence of leri water supplementation on mycelium growth, primordial appearance, fruiting body count, fruit body diameter, and wet weight, as well as the production of white oyster mushrooms (Pleurotus ostreatus). The research employed a Completely Randomized Design (CRD) with four treatments: A0 (control without leri water), A1 (20 ml of leri water), A2 (40 ml of leri water), and A3 (60 ml of leri water), with a 95% confidence level F-test. The results revealed that leri water supplementation significantly affected all observed variables. The treatment with 40 ml of leri water (A2) produced the highest mycelium growth with an average weight of 10.45 kg, the earliest primordial appearance, the highest fruiting body count (15.67), and the highest wet weight (372 kg). Meanwhile, the treatment with 60 ml of leri water (A3) resulted in the largest fruit body diameter (17 cm). Among the treatments, A2 with a 40% leri water nutrient supplement in the growing medium outperformed others, as it provided the necessary nutrients for mycelium growth and overall mushroom development.
