Abstract

A planting media composition consisting of ultisol soil, composted sugar cane residue (blotong)and husk charcoal is needed to support the growth of sugarcane (Saccharum officinarum L.) seedlings from bud chips. The aim of this research was to determine the comparison of the planting media composition consisting of the ultisol, blotong and husk charcoal on the growth of sugar cane (Saccaharum officinarum L,.) seedlings from Bud Chips in Polybags. This research used a completely randomized design (CRD) with one treatment factor, i.e. the planting media composition consisting of ultisol, blotong and husk charcoal with the following volume ratio: V1 = (1 l) + (0.5 l) + (0.5 l), V2 = (0.5 l) + (0.5 l) + (1 l), V3 = (0.5 l) + (1 l) + (0.5 l), V4 = (0.67 l) + (0.67 l) + (0.67 l). Each treatment was repeated 3 times. The parameters observed were plant height, stem diameter, shoot dry weight and root dry weight, as well as the root shoot ratio. The result showed that the comparison of the planting media composition   for ultisol, blotong and husk charcoal, in treatment V3 = (0.5 l) + (1 l) + (0.5 l) had a significant effect on plant height of 201.30 cm with an increase of 29.795%, stem diameter 21.77 mm with an increase of 38.92%, shoot dry weight 44.73 g with an increase of 158.55%, root dry weight 5.29 mm with an increase of 153.11%, root crown ratio 8.47 with an increase of 51.52 %.

Abstract

The cultivation of cocoa plants that began in nurseries, is an effort to increase cocoa production. High yields can be achieved with high-quality cocoa beans. This study aims to obtain a combination treatment of NPK inorganic fertilizer with the best Bioneensis bioorganic fertilizer to support the growth of cocoa seedlings. This study used a one-factor Complete Randomized Design. The treatment design tested was Bioneensis bioorganic fertilizer and NPK fertilizer with 5 levels of dosage and 3 replications. as follows:  b0 : Control, b1 : 7.5 g NPK fertilizer, b2 : 9.9 g Bioneensis fertilizer, b3 : 5 g NPK fertilizer (66.7% of b1) + 3.3 g of Bioneensis fertilizer (33.7% of b2), and b4: 2.5 g NPK fertilizer (33.7% of b1) + 6.6 g of Bioneensis fertilizer (66.7% of b2). and b4: 2.5 g NPK fertilizer (33.7% of b1) + 6.6 g of Bioneensis fertilizer (66.7% of b2). Implementation of research in the form of land preparation and shade,  preparation of planting media,  seedling preparation, feeding, treatment, and maintenance of plants. Plant height, stem diameter, header dry weight, root dry weight, root crown ratio, and quality index are the parameters that are measured. The results of this study concluded that treatment of 2.5 g of NPK fertilizer combined with 6.6 g of Bioneensis biofertilizer will increase plant height by 60.10%, rod diameter by 43.86%, The dry weight of the header was 183.31%, the dry weight of the roots was 229.41%, and the quality index was 189.20% compared to the control.

Abstract

Oil palm is a strategic plantation commodity that plays a vital role in Indonesia’s economy as a major contributor to non-oil and gas revenue. Its high productivity and market value make it an attractive investment. However, basal stem rot (BSR) caused by Ganoderma sp. remains a major constraint in plantation management. This study aims to compare the incidence and severity of the disease between oil palms derived from improved and non-improved seeds. The research was conducted from August to November 2024 in Suban Village, Batang Asam District, Tanjung Jabung Barat Regency using an unformatted trial design with purposive site selection. Data were collected through field symptom observations, farmer interviews, and environmental factor measurements, then analyzed qualitatively (data tabulation) and quantitatively (paired t-test). The results revealed that palms from improved seeds showed a disease incidence of 2.96% with 2.14% severity, while non-improved seeds exhibited 3.33% incidence with 1.85% severity. These findings indicate that improved seeds are relatively more resistant to Ganoderma sp. infection, although the disease severity tends to be slightly higher. This study provides important insights for disease management strategies and serves as a reference for farmers in selecting seed sources to optimize oil palm productivity.

Abstract

The use of ultisol soil as a nursery medium is constrained by low soil fertility. This study aims to determine the growth of Areca nut seedlings (Areca catechu L.) in various compositions of vermicompost and NPK fertilizer in polybags to overcome the problem availability of nutrients in the soil. This study was conducted at the Experimental Station of the Faculty of Agriculture, Batanghari University on July 7 to November 2024. This study used a completely randomized design with one factor. The treatments were vermicompost and NPK fertilizer (k) with 6 levels as follows: k0=without vermicompost and NPK fertilizer, k1= 30 g vermicompost, k2= 10 g NPK fertilizer, k3= 22.5 g vermicompost + 2.5 g NPK fertilizer, k4= 15 g vermicompost + 5 g NPK fertilizer, k5= 7.5 g vermicompost + 7.5 g NPK fertilizer. The parameters observed were plant height, stem diameter, total leaf area, shoot dry weight, root dry weight, soil water content, root volume, soil chemical analysis. The combination treatment of vermicompost fertilizer with NPK fertilizer affected all parameters, namely plant height, stem diameter, total leaf area, shoot dry weight, root dry weight, and root volume. Based on data analysis, it can be said that the k5 treatment, namely a combination of 25% vermicompost fertilizer + 75% NPK fertilizer, will increase seedling height by 27.27%, seedling stem diameter by 50.10%, total leaf area by 65.40%, shoot dry weight by 64.55%, root dry weight by 130.57%, and root volume by 96.18% when compared to the control. The k1 treatment gave the highest value of planting media water content, increasing by 25.56% when compared to the control. The combination of vermicompost fertilizer with NPK fertilizer is highly recommended in areca nut cultivation. The cost of k5 fertilization increased by 7.25%, but there was an increase in seedling height of 12.5%; stem diameter 34.57%; total leaf area 49.23%; shoot dry weight 37%; root dry weight 35.58; soil water content 26.51%, and root volume 68%. The R/C ratio of areca nut seedlings was 1.87.
