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.

It is not yet known, among the nutsedge, grasses, and broad-leaved plants, which group has the greatest impact on the yield loss of shallots. There is also no information yet on whether the application of NPK fertilizer can increase the competitiveness of shallots against weeds. For this reason, a study was conducted aiming to determine the dose of NPK fertilizer that increases the competitiveness of the plants in competition with weeds. The research results show that nutsedges significantly dominate in the presence of shallots, both in unfertilized plants and in plants fertilized with NPK Ponska at a dose of 200–400 kg ha-1, with a weighted dominance value of 59.55% – 70.87%. In contrast, the weighted dominance values for grass weeds and broadleaf weeds are 35.82% – 27.46% and 3.93% – 1.43%, respectively. The yield loss in unfertilized shallots with NPK Ponska due to weed competition was 21.57% for nutsedges, 18.96% for grass, and 7.78% for broadleaf weeds, while with fertilization using NPK Ponska at a dose of 200 - 400 kg ha-1, the losses ranged between 22.085% – 28.755%, 11.37% – 14.77%, and 3.404% – 3.711%, respectively. Shallots that were kept weed-free during their growth and fertilized with NPK Ponska 400 kg ha-1 achieved the highest yield of fresh table onions compared to other treatments, namely 400.94 g m-2, at an ideal population density of 64 clumps m-2. The lowest yield was observed in plants that had weeds during their growth and were also fertilized with NPK Ponska 400 kg ha-1, with 76.19 g m-2 at a population density of 20.33 clumps m-2

Root growth dynamics in cacao (Theobroma cacao L.) play a critical role in determining water and nutrient uptake, supporting canopy development, and sustaining productivity under diverse environmental conditions. Unlike the canopy, which is relatively easy to observe, root growth is often overlooked because it occurs belowground. This review aims to synthesize current knowledge on the rhythmic growth of cacao roots, particularly fine roots, and their relationships with canopy growth, water availability, nutrient acquisition, shade systems, and orchard management. A narrative-integrative literature review was conducted using scientific articles, technical publications, and relevant research reports. The review indicates that cacao root growth is rhythmic and closely associated with shoot growth cycles. During leaf flushing, root activity may decline because assimilates are preferentially allocated to developing young leaves. Fine roots serve as the primary organs for water and nutrient uptake, but their growth and function are strongly influenced by soil moisture, aeration, organic matter, soil compaction, root competition with shade trees, and nutrient distribution in the rooting zone. Agroforestry systems may improve microclimate and soil conditions, yet they may also intensify belowground competition when shade tree species and spacing are not properly managed. This review emphasizes that cacao root management should include soil moisture conservation, fertilization based on active rooting zones, organic matter maintenance, shade regulation, and prevention of soil compaction and waterlogging. Understanding root growth rhythms is essential for developing productive, adaptive, and sustainable cacao orchard management.

Since physic nut (Jatropha curcas L.) is heterozygous, sexual propagation results in great genotypic and phenotypic variability. Development of efficient techniques for asexual propagation would benefit the nursery industry as this would lead to selection and production of particular clones with desirable characteristics. Therefore, two following studies were conducted from September until December 2007. The objective was develop a protocol for vegetative propagation of physic nut by stem cutting in different size of cutting. The first experiment was dealt with stem cutting length (20 cm, 25 cm, and 30 cm) at the same size of diameter (2.5-3.0 cm), and the second experiment was dealt with diameter of stem cutting (3 cm, 2.5-2.9 cm, 2.0-2.4 cm, and 1.5-1.9 cm) at the same size of length (30 cm). Each of experiment was designed in Completely Randomized Design with three replications. Each experimental unit consisted of 25 seedlings. The result showed that cutting growth varied depending on length and diameter of stem cutting. However, better seedling growth and better survival of young plant of physic nut can be obtained from stem cutting with 20-30 cm in length and stem cutting with 2.0-2.9 cm in diameter. Key words: cutting diameter, cutting length, Jatropha, survival, transplanting

Seed and oil production of physic nut (Jatropha curcas) is the function of planting material, growing condition, and alsocanopy architecture maintenance. The objective of the research was to determine the effect of pruning time on yield of physicnut. An experiment was conducted from November 2007 to November 2010 in North Lombok, West Nusa Tenggara using WestLombok genotype. The experimental design was randomized block design with three replications. There were four treatmentsi.e. a) without pruning, b) pruning at planting time, c) pruning of 1-year old trees at dormance period (after harvesting), andd) pruning of 2-years old trees at dormancy period (after harvesting). Results showed that development and maintenance ofphysic nut canopy is one of important agronomic practices to obtain high seed production. The best time for pruning during3-years production cycle was at the end of harvest of 1-year old trees which could yield more than 4 tonnes seed ha-1 .

The fl owering biology of physic nut (Jatropha curcas L.) has been observed in dry land (sandy entisol soil type) of AmorAmor, North Lombok, West Nusa Tenggara. Exploration was conducted in several areas where high population of physic nut grown as fence plant was found. Quantitative, descriptive, and observation data were collected for each accession during two-year growth period. Randomized block design was used in this research with three replications from November 2006 until November 2008. Treatments consisted of fi ve ecotypes, i.e. West Lombok, Central Lombok, East Lombok, Sumbawa, and Bima. The results showed that fl owering of physic nut West Nusa Tenggara ecotypes was produced continuously during a year, while the peak number of fl ower was only twice e.g. at the early (November-February) and at the end (April–May) of rainy season. Duration of the fl owering process took around 3 days for female fl ower, around 2 days for male fl ower, and 7-10 days for total fl ower per infl orescence. Higher genetic potential for female fl ower formation was found on West Lombok, Sumbawa, and Bima ecotype. This result should be useful information for breeding programme of physic nut. However, since physic nut is a perennial plant, further study is needed especially on the technology to control fl owering. Keywords: dry season, fl owering, fruiting, rainy season,

The aim of this experiment was to evaluate the pattern of yield improvement of Jatropha curcas L. of West Lombokecotype at dry land of North Lombok, West Nusa Tenggara during four years production cycle. The experiment was conductedin randomized complete block design (RCBD) using three types of propagules (i.e., stem cutting, seed, and seed followed bypruning after transplanting) and three replications from November 2006 to November 2010. The results showed that yieldwas increased as plant age increased. Plants cultivated during rainy season had higher yield compared to those cultivatedduring dry season. However, the oil content of nuts was slightly higher when harvested in dry season than in rainy season.Yield was also affected by plant material used. In the fi rst year, plants propagated by stem cutting had the highest yield. Inthe second, third, and fourth year, plants propagated from seed followed by pruning produced the highest nut dry weight.During four years production cycle, yearly yield improvement was about 2-3 times than the previous year and did not followthe geometrical progression based on dichotomy branching pattern of Jatropha.Keywords: dry land, productivity, pruning, seed oil content, type of propagule

Abstract. Santoso BS. 2011. Variation in oil contents and seed and seedling characteristics of Jatropha curcas of West Nusa Tenggara selected genotypes and their first improved population. Nusantara Bioscience 3: 130-135. This study describes variation in seed and seedling characters of Jatropha curcas Linn. of West Nusa Tenggara selected genotypes. Exploration was conducted in several areas where large population of this species grown as fences were found. Five selected genotypes were then grown in experimental fields to let mass selection to obtain the first improved population for each genotype. Seeds of wild population (P0) and those of selected trees as the first improved population (IP-1) were subjected to this study. Seed and seedling characteristics were measured. The result indicated that considerable genetic variability existed among the five J. curcas of West Nusa Tenggara selected genotypes and within each genotype population for seed and seedling characteristics. Genotypes of West Lombok, Sumbawa, and Bima performed exceedingly better than those of Central Lombok and East Lombok. Therefore, this study has suggestions for identifying potential seed sources of J. curcas and these existing genetic variability provides breeders with materials in crop improvement program.
