Abstract

Stunting in children under five remains a significant public health issue in Indonesia, particularly in West Sumatra, where prevalence rates exceed the national average. Addressing this challenge requires improving nutritional intake, focusing on essential micronutrients like zinc (Zn) and iron (Fe). Biofortification is a promising agricultural strategy to enhance the nutritional quality of staple crops such as rice. This study aims to explore and evaluate the Zn and Fe content of local rice genotypes from West Sumatra, which hold potential for biofortification programs.Twenty-eight rice genotypes, including 27 local genotypes and one control (Inpari Nutri Zinc), were analyzed for Zn and Fe content. The results showed that the control variety, Inpari Nutri Zinc, exhibited the highest Zn (31.30 ppm) and Fe (19.85 ppm) content. Among the local genotypes, Puluik Mutia (Zn: 28.40 ppm, Fe: 18.30 ppm), Kuning Aro (Zn: 27.60 ppm, Fe: 18.20 ppm), and Rampai Kuning (Zn: 26.20 ppm, Fe: 18.05 ppm) displayed the highest Zn levels, while Manggung (Fe: 18.85 ppm) had the highest Fe content. These findings highlight the significant variability in micronutrient content among local genotypes, emphasizing their potential as germplasm for biofortification breeding programs.This research represents the first systematic exploration of Zn and Fe levels in local rice genotypes from West Sumatra. The novelty lies in identifying high-Zn and Fe genotypes, particularly those with firm texture preferences, which could support biofortification efforts and provide a sustainable solution to combat stunting. Future research should focus on environmental interactions and agronomic practices to further optimize the micronutrient content in local rice varieties

Abstract

Seedless watermelons, both seeds and fruits, possess a significantly higher economic value than their seeded counterparts. Serif Saga Agrihorti, a variety developed by the Tropical Fruit Research Institute, offers several advantages, including a sweet taste, high fruit yield, bright red flesh, and large fruit size. However, it is characterized by a relatively high number of seeds. The development of a new seedless variety from Serif Saga Agrihorti is crucial. Polyploid induction using mutagenic agents like colchicine is an effective method to obtain tetraploid female parents. This study aimed to identify the optimal method and colchicine concentration for inducing polyploidy in watermelons and to produce putative tetraploid plants. Polyploid induction was conducted using two methods: directly applying colchicine solution to plant shoots and soaking seeds in colchicine solution for 24 and 48 hours at concentrations of 0.2% and 0.4%. The observed traits included stem diameter, leaf length and width, stomatal length and width, pollen diameter, pollen viability, male and female flowering periods, harvesting time, fruit weight, fruit diameter, seed count, and seed dimensions (length and width). Data were analyzed using an unpaired t-test using the Statistical Tools for Agricultural Research (STAR) software. The results identified four putative tetraploid genotypes based on morphological observations of pollen diameter, stomatal size, and seed dimensions. In conclusion, seed soaking in colchicine solution effectively induces polyploidy in watermelons compared to shoot application.

Abstract

Pruning, combined with fertilization, is a feasible agricultural technique to extend the harvest period of bird's eye chilli plants, thereby enhancing farmers' income. This study aimed to examine the interaction between controlled-release fertilizer (CRF) and NPK doses and to determine the optimal dosage of both fertilizers, considering the residual effects of CRF on the growth and yield of bird's eye chilli plants following pruning on Ultisol soil. The experiment was conducted from September 2024 to January 2025 at the Experimental Farm of the Faculty of Agriculture, Universitas Andalas. A Split-Plot Randomized Complete Block Design was employed, with the main plot representing the residual effects of CRF, while the subplots corresponded to different CRF and NPK dosages. The main plot treatments included CRF residual effects at 750 kg/ha, 1000 kg/ha, and 1500 kg/ha, whereas the subplots consisted of CRF application at 750 kg/ha, 1500 kg/ha, and NPK at 1200 kg/ha. Data were subjected to variance analysis (ANOVA) and further assessed using Duncan's Multiple Range Test (DMRT) at a 5% significance level. The results indicated no statistically significant interaction between CRF and NPK dosages and the residual effects of CRF. Applying CRF at 750 kg/ha was the most effective across all residual CRF levels among all tested treatments. The residual CRF dose of 1500 kg/ha positively impacted plant development and fruit production. The findings also revealed that the residual CRF effect contributed to an increased nitrogen supply in the soil, reducing the necessity for additional nitrogen fertilization for bird's eye chilli after pruning cultivation.

Abstract

The koro beans from the Canavalia genus serve as a crucial alternative protein source for ensuring national food security. Cultivation can be targeted toward marginal lands, which are abundant in Indonesia.This research aims to evaluate the growth response of different Canavalia spp. accessions from three species under varying salinity conditions. Conducted between September 2023 and March 2024 at Pantai Pasir Putih, Bungo Pasang in Padang City, the study involved planting five accessions of Canavalia spp., two from Canavalia gladiata, two from C. maritima, and one from C. cathartica on fields with low salinity (1.2 dS/m) and moderate salinity (3.8 dS/m). The experimental setup was a Randomized Complete Block Design with two replications per treatment, totalling 20 experimental units. Data were analyzed using combined analysis of variance (combined ANOVA), followed by Duncan's test at a 5% significance level. Correlation analysis determined the relationship between salinity levels and plant growth variables. The findings revealed that the growth of accessions decreased under moderate salinity, except for the Cm.Halmahera and Cm.Bengkulu accessions, which exhibited improved growth. Significant interactions between accessions and salinity levels were observed for stem length, branch number, and stem diameter, particularly 24 weeks after sowing, indicating an optimal period for selecting salinity-tolerant accessions. A strong negative correlation between salinity levels and plant growth was found, indicating that increased salinity suppresses plant growth. Based on salinity tolerance indices, Canavalia maritima accessions Cm.Halmahera and Cm.Bengkulu showed greater adaptability to saline conditions compared to the other accessions.
