Evaluation of Turmeric (Curcuma longa L) Genotypes for Growth and Yield Attributes in Plains of Eastern Nepal

Abstract

An experiment was conducted in order to identify the productive genotype of turmeric for the plains of Nepal. In 2017 and 2018, seven promising turmeric genotypes (CI 0207, CI 0205, CI 9102, CI 1312, CI 0503, CI 0507, and CI 0201) were compared with KKH-1 in a Randomized Complete Block Design with four replications at the Directorate of Agricultural Research, Tarahara, Nepal. The plants were 30 cm x 30 cm apart, with 40 plants per 3.6 m2 plot area. Cultural practices were followed in accordance with the recommendations. Analysis of variance, correlation, cluster, and GGEbiplot analysis were performed on the observed data. From the pooled analysis of two years of data, the results showed significant differences in plant height and fresh rhizome yield among genotypes. The rhizome yield of KKH-1 was found significantly higher (19.36 t ha-1) than CI 0205 and CI 9102 and at par with other genotypes. Weight of mother rhizome had significant positive correlation (r = 0.602**) with yield of fresh rhizome. Though KKH-1 yielded the highest fresh rhizome, the cluster and GGEbiplot analysis identified CI0207 as one of the potential turmeric clones next to KKH-1.

Sustainable methods for growing turmeric: Evaluating the effects of synthetic and organic fertilizers on vegetative and reproductive attributes

“…The mean leaf count recorded at harvest stands at 8.93. In contrast, Chapagain et al (2021) reported leaf count of just 7.69 slightly lower results compared to our findings. The highest leaf count observed in our study could be attributed to various factors, including differences in soil fertility, climatic conditions, cultivation techniques, and varietal disparities, all of which influence leaf development and overall plant vigor.…”

“…Turmeric (Curcuma longa L.) is a perennial herbaceous plant belonging to the ginger family, Zingiberaceae (Ferdous et al, 2018), extensively cultivated in the tropical and subtropical regions of the world, including Nepal (Baral et al, 2021;Chandana et al, 2024a). It holds significant cultural, culinary, and medicinal value (Chapagain et al, 2021), with its rhizomes being prized for their vibrant color, Flavors, and therapeutic properties (Hossain et al, 2007). Turmeric has been cultivated across diverse ecological zones of Nepal, spanning from the eastern to western regions, encompassing the inner terai, foothills, and mid-hills up to an altitude of 1600 meters above sea level (Mehata et al, 2022a;Rajbanshi et al, 2023;).…”

“…As of 2078/79 BS, the total yield of turmeric per hectare in Eastern Nepal, averaging between 18 to 22 tons ha -1 under favorable conditions, has been reported by (Timsina et al, 2011). In Eastern Nepal, turmeric cultivation serves as a vital component of agricultural practices and plays a crucial role in the socio-economic fabric of the region (Chapagain et al, 2021;Datta et al, 2017). The cultivation of turmeric in Eastern Nepal is typically characterized by smallholder farmers employing traditional farming techniques (Chapagain et al, 2021).…”

The cultivation of turmeric in Eastern Nepal is typically characterized by smallholder farmers employing traditional farming techniques (Chapagain et al, 2021). However, despite its importance, turmeric production faces various challenges, including declining soil fertility, pest and disease pressures, erratic weather patterns, and fluctuating market prices (Baka et al, 2021).…”

Identification and Registration for High-Yielding Strain through ST and MLT of Curcuma caesia Roxb. (Jor Lab KH-2): A High-Value Medicinal Plant

“…Evaluation by GGE biplot of seven turmeric genotypes from Nepal was performed to identify traits helpful in turmeric selection. A total of 71.91% variation was observed from the two principal components (PC1 and PC2), among which 39.08% and 32.83% variation was exhibited by PC1 and PC2, respectively [ 46 ]. Another study in Curcuma angustifolia was carried out to identify a high-yielding stable genotype.…”
