Abstract

Tabah Bamboo has potential that needs to be developed both in the food sector, industry and environment. This type can be processed into food ingredients worth exporting, especially bamboo shoots. To meet the needs of raw materials need to multiply plants in the field through nurseries one of them using stem cuttings. Root growth is an indicator of the success of nurseries using cuttings. The research was conducted at KHDTK Rarung, Central Lombok from October 2020 until January 2021.  The purpose of the study was to determine the influence of concentration IBA (Indole Butyric Acid), growing media, and long soaking cuttings in the solution of IBA concentration on the growth of cutting roots. The results showed that the best root emergence time occurred in a combined concentration of 400mg.1-l IBA and soil media +cocopeat + manure. Each factor independently has a noticeable effect on the number of roots. Concentration of 400mg.1-l IBA, soaking length of 1 hour, and soil media+cocopeat+manure result in a better number of roots. Combination concentration of 400mg.1-l IBA and a 1-hour soaking length result in better root length at 43 hst, while a combined concentration of 400mg.1-l IBA and soil media + cocopeat + manure produce better root length at the age of 50 hst and 57 hst. Combination concentration of 400mg.1-l IBA, soaking length cuttings 1 hour, and soil media + cocopeat + manure produce fresh weight and dry roots best

Abstract

Low nutrient along with intense sunlight levels in sandy drylands, often lead to poor crops yield. This study examined the effects of soil amendments and shading on the yield of red chili plants cultivated in a sandy (70% sand, 15% clay and 15% silt) dryland environment. The experiment was conducted in Gumantar Village, North Lombok Regency from May to September 2024. The C-organic content of the soil was 1.11% with only 0.09% of total nitrogen. The soil amendment treatments included no soil amendment, chicken manure, and seaweed biochar. The shading treatments consisted of two levels: no shading and shading using a 200-micron UV plastic with 14% diffusive ultraviolet ray. All treatments were arranged factorially using a randomized block design with three replications. The results indicated that soil amendments and shading did not significantly affect plant growth, certain soil chemical properties, or microbial populations, possibly due to its short time effect. However, both types of soil amendments and UV plastic shading increased the yield of red chili plants by approximately 6.0% compared to the treatment without any amendments or without shading. This study shows that soil amendment and shading with UV plastic improve tomato yield in sandy dryland soils.

Abstract

The yield of tomato plants in dryland areas has been suboptimal due to environmental constraints such as poor soil health and high sunlight intensity. Appropriate agronomic modifications are necessary to improve crop yields while maintaining soil health. This study investigated the impact of various agronomic modification treatments on the growth and yield of tomato plants in dryland regions. The experiment was conducted in Gumantar Village, North Lombok Regency, during the dry season from June to August 2023. The agronomic modifications included a seaweed biochar treatment at a rate of 10 tons per hectare and 45% shading, with a control group that had no modifications. Three treatments were tested on two varieties of tomato plants: hybrid and local superior. The treatments were organized with four replications in a randomized complete block design with split plots, where agronomic modifications served as the main plots and the tomato varieties as the subplots. The results indicated that the interaction of agronomic modifications and plant varieties impacted the growth of tomato plants and various environmental factors. The hybrid variety under shading treatment exhibited the best growth. Additionally, this hybrid variety produced 59.6% more fruit than the local superior variety, yielding an average of 66 fruits and weighing 3.00 kg per plant. This study suggests that incorporating agronomic modifications, such as biochar treatment and selecting the appropriate variety, can enhance tomato yields in dryland areas.
