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

Kacang koro dari genus Canavalia dapat dimanfaatkan sebagai sumber protein alternatif yang penting untuk ketahanan pangan nasional. Pembudidayaannya dapat diarahkan pada lahan marginal yang ketersediaannya cukup luas di Indonesia. Penelitian ini bertujuan untuk melihat respon pertumbuhan berbagai aksesi kacang koro yang berasal dari tiga spesies berbeda pada dua kondisi lahan yang terpapar salinitas. Penelitian dilaksanakan pada bulan September 2023-Maret 2024 di Pantai Pasir Putih, Bungo Pasang Kota Padang. Sebanyak 5 aksesi Canavalia spp. yaitu 2 aksesi spesies Canavalia gladiata, 2 aksesi spesies C. maritima, dan 1 aksesi spesies C. cathartica ditanam di lahan dengan dua kondisi salinitas yaitu salinitas rendah (1,2 dS/m), dan salinitas sedang (3,8 dS/m). Percobaan didesain dalam Rancangan Acak Kelompok dengan masing-masing dua ulangan sehingga terdapat 20 satuan percobaan. Data dianalisis menggunakan sidik ragam gabungan (combined ANOVA) dan dilanjutkan dengan uji Duncan pada taraf nyata 5%. Analisis korelasi dilakukan untuk melihat hubungan tingkat salinitas dengan variabel pertumbuhan tanaman. Hasil penelitian menunjukkan terjadinya gangguan pertumbuhan kecuali aksesi Cm.Halmahera dan Cm.Bengkulu yang memperlihatkan respons peningkatan pertumbuhan dengan meningkatnya salinitas. Aksesi berinteraksi dengan tingkat salinitas pada pengamatan panjang batang, jumlah cabang dan diameter batang terutama pada umur 24 MST, mengindikasikan periode waktu ini ideal untuk menyeleksi aksesi yang toleran terhadap salinitas.  Korelasi negatif dan kuat antara tingkat salinitas dan pertumbuhan tanaman menunjukkan bahwa peningkatan salinitas menekan pertumbuhan tanaman. Berdasarkan nilai indeks toleransi, maka aksesi Cm. Halmahera dan Cm. Bengkulu dari spesies Canavalia maritima memiliki kemampuan adaptasi yang lebih baik terhadap salinitas dibandingkan aksesi lainnya.

Abstract

The utilization of superior hybrid varieties is pivotal in enhancing national maize productivity. Therefore, the continuous development of cultivars specifically adapted to distinct agroecosystems remains imperative. To that end, this study evaluated six inbred lines and 15 single-cross hybrids derived from a half diallel mating design to assess the combining ability of these inbred lines and examine the agronomic performance and heterotic expression manifested in the resulting hybrids. All genotypes, including the hybrids, inbred parents, and a check variety (P32), were tested using an RCBD with two replications in Nagari Situjuah, West Sumatra, Indonesia. The data were analyzed using F-tests followed by a planned LSD test with SAS software at the 5% significance level. PCA and path analysis were performed using RStudio, while GCA and SCA were analyzed using Diallel-SAS software. Results showed that the UZ 9 line performed the highest GCA for growth, flowering and yield-related traits. Hybrids UZ 3><UZ 9 (H2), P137-1><R2 (H14), and CLYN><R2 (H15) exhibited the best SCA values, coupled with superior agronomic performance, positive and high heterosis, heterobeltiosis, and standard heterosis for yield, achieving up to 11 tons hectare⁻¹, comparable to P32. PCA further supported these findings, which revealed that H2, H14, and H15 were associated with shorter flowering, harvesting periods and higher kernel yield. Path analysis identified kernel weight ear⁻¹ as the most influential variable affecting kernel yield hectare⁻¹. These findings highlight H2, H14, and H15 as promising hybrids with strong potential for further development and evaluation before release as new superior hybrid varieties.

Abstract

The germination process is the key to plant phenology, which significantly influences the success of early plant growth. Some seeds have a dormancy, so the germination process is hampered or does not occur. However, dormancy-breaking treatments in plants have been widely reported, such as breaking the dormancy of sugar palm seeds through physical scarification. This research aims to determine the best scarification position to break the dormancy of sugar palm seeds. This research was carried out at the Seed Technology Laboratory, Faculty of Agriculture, Universitas Andalas from July to October 2023. The design was completely randomized with scarification in two position variations, the operculum (A1) and dorsal (A2) points, repeated thrice. The results showed that the position of seed scarification affected the emergence time of cotyledon petioles and coleoptiles, germination capacity, and seed moisture content. Scarification at the operculum point requires a dormancy break of 16 DAP (Days After Planting) compared to 29 DAP for the dorsal. Seed viability was good in seeds sacrificed at the operculum point, with a germination percentage of 81.94%. Keywords: dorsal, operculum, cotyledon petiole

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
