Abstract

Drylands with limited resource support need to increase their productivity. One indicator of land productivity is the land equivalence ratio (LER). This research aimed to study the growth and yield of red chili due to the effect of varieties and peanut planting times in intercropping systems to increase dryland productivity. One experiment was conducted in Amor-amor Hamlet, Gumantar Village, Kayangan Sub-district, North Lombok Regency, from March to August 2023. The red chili varieties tested were Baja MC (hybrid) and Landung (non-hybrid). Meanwhile, peanut (Hypoma 2 variety) planting time was at the same time, one week after planting (WAP) of chili and 3 WAP. The treatments were arranged factorially using a Randomized Block Design with three replications. All component crops had monoculture treatments to calculate LER. The results showed no interaction between variety and planting time on all parameters observed. Variety had no significant effect on growth and LER but significantly affected the yield of chili. The Landung variety produced higher yields than the Baja MC variety. Planting time treatment had no significant effect on growth and LER but significantly affected the yield of chili. The planting time of peanut that produced the highest yield was 3 WAP. The intercropping of chili with peanuts at all planting times increased dryland productivity with LER values greater than 1.0

Abstract

Despite having a considerable potential area, the optimal utilization of dry land is challenging due to the generally low soil moisture content and fertility of dry land in Indonesia. This is evidenced by the intrinsically low organic matter content in dryland soils. Therefore, this article aims to provide information on the potential application of chicken manure to enhance soil fertility and health or to rehabilitate suboptimal dry lands in Indonesia. The methodology used in this article is qualitative, based on a literature review. One approach to improving the condition of dry land in Indonesia is the application of chicken manure, which acts as a soil conditioner and enhances overall soil fertility and health. The results of the study indicate that using chicken manure on dry land can increase crop production, thereby positively correlating with the profits of dry-land farmers.

Abstract

Cultivating tomato plants in dry, sandy soils aims to achieve high yields while enhancing or maintaining soil fertility. This study investigates the effects of soil amendments and ultraviolet (UV) plastic shade on tomato yield and various indicators of soil fertility. The experiment was conducted in the dryland of Gumantar village, North Lombok Regency, Indonesia, during the dry season from May to August 2024. The soil amendment factor included three levels: no soil amendment, chicken manure, and seaweed biochar. Meanwhile, the shading factor consisted of two levels: no shading and shading with UV plastic (200-micron thickness, which transmits 86% of UV light). All treatments received inorganic NPK fertilizer (16-16-16) at a rate of 1,200 kg per hectare. Treatments were arranged factorially using a randomized block design with three replications. Results showed an interaction between soil amendments and shading that affected soil pH, the number of fruits, and fruit weight per plant and plot. The highest fruit weight per plant, recorded at 4.2 kg with 100.7 fruits, was achieved using seaweed biochar and shading. The treatments slightly improved soil fertility indicators, such as soil organic carbon (C-organic), total microbial count, and cation exchange capacity. Applying soil amendment and UV plastic shading can be a sustainable practice for tomato crops production in sandy dryland soils
