Abstract

Oil palm (Elaesis guinensis Jacq.) is a type of plantation/industrial plant in the form of straight- stem trees belonging to the Arecaceae family and Cocoideae subfamily. The horn beetle (Oryctes rhinoceros) is a pest of oil palm stem borer. The aim of the study was to determine the effectiveness of entomopathogenic fungi in controlling the larvae of the oil palm stem borer (O. rhinoceros L.). The study used a completely randomized design (CRD) consisting of 9 designs and 3 replications. The treatments consisted of M0 = control, M1 = M. anisopliae at a dose of 5 g/jar, M2 = M. anisopliae at a dose of 10 g/jar, M3 = M. anisopliae at a dose of 15 g/jar, M4 = M. anisopliae at 20 gr/jar, B1 = B. bassiana at a dose of 5 gr/jar, B2 = B. bassiana at a dose of 10 gr/jar, B3 = B. bassiana at a dose of 15 gr/jar, B4 = B. bassiana at a dose of 20 gr/jar jars. Observational parameters were the mortality percentage of O. rhinoceros larvae and symptoms of attack by O. rhinoceros larvae infected with entomopathogenic fungi. The results showed that the highest percentage of larval mortality of O. rhinoceros was M4 and B4 treatments, namely 100% and 93.33%, respectively, at 12 days of observation. Symptoms of larval death are pale larvae then turn brown or black, after death the larvae will harden like a mummy with a smaller posterior part.

Abstract

Weed control is one of the determining factors for achieving high oil palm yields, at the same time fertilization is necessary to provide nutrients for plants. This study aims to: (1) determine the interaction between the herbicide IPA Glyphosate with fertilizer Urea+SP-36+KCl on weed control and growth of immature oil palm. (2) to obtain an effective dose of herbicide to control weeds, and to obtain the best dose of Urea+SP-36+KCl fertilizer for the growth of oil palm. The study was conducted using a factorial Randomized Block Design (RBD) consisting of 2 factors and 8 treatment combinations. The first factor is herbicide doses of IPA Glyphosate (1,920 g/ ha, 2,400 g/ha, mechanical weeding, and control) and the second-factor is fertilizer doses of Urea+SP-36+KCl (600 g Urea +750 g SP-36 +700 g KCl/plant, and 700 g Urea + 850 g SP- 36 + 800 g KCl/plant). The data were analyzed for variance and if significantly different then continued with Duncan’s New Multiple Range Test (DMNRT) at the 5% level. The results showed that there was no interaction between the dose of the herbicide IPA Glyphosate with fertilizer Urea+SP-36+KCl on weed control and growth of immature oil palm. The herbicide dose of I PA Glyphosate which was effective in suppressing the dry weight of weeds was 1,920 g/ha because it was effective in suppressing the dry weight of weeds up to 12 weeks after application (WAA) and obtained the smallest average of weed dry weight. Urea+SP-36+KCl fertilizer application did not affect the vegetative growth parameters of immature oil palm.

Abstract

Cameroon and Angola, accession palms oil, were two plants with different flower architectures such as bunch size, bunch length, number of spikelets and flowers, and volatile compounds produced. The difference in flower characteristics was thought to affect the presence of flower-visiting insects in the two palm oil accessions. The study aimed to determine the insects that visit Cameroon and Angola palm oil flower accessions. Insects that visit flowers were collected directly, using yellow pan traps, swing nets, and aspirators. Collected flower-visiting insects were identified as species. Diversity and evenness were calculated using the Shannon diversity index and the Simpsons’ evenness. The total number of flower-visiting insects collected was 2039 individuals. In the Angola accession, 150 individuals were found consisting of 5 orders, 10 families, and 14 species. Insects that visited Cameroon’s accession of palm oil flowers were 1889 individuals consisting of 8 orders, 16 families, and 22 species. Angola accessions’ diversity and evenness index were higher than Cameroon’s, namely 1.50; 1.14 and 1.14; 0.52. Flower-visiting insects that act as pollinators were Elaeidobius kamerunicus, Pyroderces Sp, and Thrips hawaiiensis.

Abstract

Crickets feces manure is the solid waste produced by cricket metabolism which contains some nutrients. Its application as the mix of planting medium is very potential for increasing plant growth. The objectives of this study were to determine the effect of several doses of crickets feces manure on the growth of cacao (Theobroma cacao L.) seedling and to obtain the best dose of it for growth of cacao seedlings. This research was a Completely Randomized Design (CRD) with 5 treatments and 4 replications to obtained 20 experiment units, and each of it consisted of 3 plants, so there were total 60 plants. The research was carried out in the experimental field of the 3rd Campus Andalas University, Dharmasraya. The observation data were analyzed by analysis of variance (F -test) and continued by the Duncan’s New Multiple Range Test (DNMRT) at 5% level significantly. The results showed that the crickets feces manure contained 2.70% N, 0.56% P, 2.24% K, 10.16% C, 3.76% C/N, 1.47% Ca, 0.69% Mg, and 0,28% Na. Application of crickets feces manure influences the growth of cacao seedlings on the variables of plant height, stem diameter, number of leaves, leaf length, and leaf width. Application of crickets feces manure with a dose of 50 g / polybag is the efficient treatment for the growth of cacao seedlings.

Abstract

Coffee is a estate commodity that plays an important role in the economy of Indonesian. Plant nursery with proper planting medium is one of the important cultivation efforts to produce optimal coffee production. The objectives of this research were to study the effect of coffee rind compost on the growth of robusta coffee (Coffea canephora) seedlings and to obtain the best dose of it on the growth of robusta coffee. This research was conducted for 4 months at the experimental field of 3rd Campus, Andalas University where located in Dharmasraya District at altitude of 131 m above sea level. Experiment was arranged according to a completely randomized design (CRD) consisted of 5 treatments and repeated 5 times, in order to obtain 25 experimental units, each of it contained 2 sample plants, so that there were 50 plants in total. The results showed that the application of coffee rind compost had a significant effect on the growth of robusta coffee (C. canephora) seedlings on the variables of plant height, stem diameter, number of leaves, leaf length, and leaf width. The best dose of coffee rind compost to support the growth of robusta coffee seedlings was 300 g / polybag.

Abstract

Cacao (Theobroma cacao L.) is one of the plantation crop that has high economic value. Therefore it is important to carry out cacao cultivation as recommended. The objective of this study was to collect data on the cultivation characteristics on smallholder cacao plantations where located in Panti Sub-district, Pasaman District. This research was conducted from August until November 2021 in Panti Sub district, Pasaman District the present research was carried out using a survey method by purposive sampling, with the criteria that cacao crops have produced and the sample includes 10% of the smallholder cacao crops area in Panti Sub-district, pasaman District. The aspects that are included in the characteristics of cacao cultivation are in terms of land preparation, crop maintenance, the techniques for pest and disease control, as well as aspects of harvest and yield. The results showed that 80% of cacao farmers in Panti Sub-district had carried out cacao cultivation according to Puslitkoka standards, but its 20% have not carried out cacao cultivation according to the recommendations, including the aspects of land preparation, crops maintenance, and harvestthat were not appropriate the origin of planting material was unclear, unknown of the clone types, pest and disease attacks are still high and sanitation activitie. Are irregular.
