Seasonal Changes in Photosynthate Partitioning in High Yielding Sweet Potato Varieties under Varied K Nutrition Levels
Arcc Journals
Background: Potassium is a major nutrient needed by the crops including tuber crops. It is essential for tuber initiation and bulking process. Varietal differences in potassium uptake and utilization in many crops were reported. As many varieties of sweet potato are released so far, studies on understanding the variations in potassium accumulation and its influence on tuber yield are essential. Methods: Field experiments were conducted during kharif and rabi seasons, 2021 with an objective to assess the seasonal influence and potassium nutrition [0 kg K 2 O/ha (K 1), 50 kg K 2 O/ha (K 2), 75 kg K 2 O/ha (K 3) and 100 kg K 2 O/ha (K 4)] on growth and tuber yield of five sweet potato varieties-four high yielding varieties (HYV) and one local variety [Bhu Krishna (V 1), Sree Arun (V 2), Sree Bhadra (V 3), Bhu Sona (V 4) and Kanjanghad Local (V 5)]. There were 20 treatment combinations replicated thrice in a randomized block design. Result: Significantly higher tuber yield (17.01 t/ha) during kharif season was recorded by variety Bhu Sona. But during rabi season, Sree Arun was superior with a tuber yield of 23.92 t/ha. The potassium nutrition up to 75 kg K 2 O/ha increased the yield of sweet potato in rabi season. Interaction effect of two factors was also significant with respect to tuber yield, total chlorophyll content and tuber K content. Potassium harvest index (%) and potassium accumulation value (g/plant) also significantly varied between varieties and K levels.

Performance of High Yielding Sweet Potato Varieties under Different Seasons
Syama S Menon, KAU
In sweet potato, though a number of high yielding varieties are available for cultivation, there is lack of information on suitability of various varieties to different seasons. The results of the study will be useful to recommend varieties ideal for different seasons. Field experiments were conducted during Kharif, Rabi and Summer seasons from 2021 to 2022 with an objective to assess the seasonal influence on growth and tuber yield of five sweet potato varieties [High yielding varieties were Bhu Krishna (V1), Sree Arun (V2), Sree Bhadra (V3), Bhu Sona (V4) and local variety was Kanjanghad Local (V5)]. Randomized Block Design was followed with four replications. Variety Bhu Sona recorded significantly the highest vine length (211.38 cm) compared to other varieties and variety Sree Bhadra (114.71 cm) and variety Kanjanghad Local (112.54 cm) recorded significantly lower vine length. Sree Arun and Bhu Sona were the superior varieties and recorded significantly higher average tuber wei...

Agronomic Evaluation of Sweet Potato (Ipomoea batatas L.) Germplasm

Sweet potato (Ipomoe batata L.), which originated in tropical America, has become a very important crop in the Asian tropical and temperate countries (Bharathi et al., 2005). Its economic importance is next to the major starch producing food crop such as wheat, rice, barley, potato and cassava. About 90% of sweet potato in the world is grown in Asia, mostly in the East and to some extent in the Southeast Asia (Villareal, 1982). With its wide adaptability, high yielding ability and tolerance to enviornmental stress, sweet potato plays an important role in many developing countries for food supplementation, vegetable use and starch processing (Bourke, 1982). Tuber production of sweet potato depends greatly on cultivar, time of planting, local climatic condition and cultural techniques followed. Sweet potato is a highly heterozygous and cross pollinated crop in which many of the traits show continuous variation. Since it is highly heterozygous, there is extensive variability within the...

This study was carried out to evaluate best germplasm of sweet potato for physiochemical characters. For this, research work was carried out in sixteen diversified sweet potato germplasm under randomized block design with three replications at Department of Horticulture, Rajasthan College of Agriculture, Udaipur. All parameters were observed at the end of harvest of crop. Results revealed that sweet potato vines are rich in nutritive value as protien content in vines ranges from 3.02 % to 7.38% while magnesium ranges 443.73 ppm to 471.84 ppm and this crop can be utilized as an alternative feed resource for ruminants to reduce competition between animals and humans.

The present study aims to assess the genetic and multivariate component analysis of processing traits, yield traits, weevil resistance and other tuber traits in sweet potatoes based on the evaluation of 12 genotypes, including checks for yield and processing. Significant variability for tuber physical, processing and vine traits was observed. Nearly 75% of the genotypes had dry matter content (>30%), 50% had starch content (>20%), and none was resistant to sweet potato weevils. High genotypic and phenotypic variation, heritability and genetic advance were observed for tuber yield, tuber girth, total sugar and weight. Among the 13 phenotypic traits used in the present study, multivariate analysis identified only eight, contributing to 83.67% of the variation. UPGMA clustering yielded two major clusters and five sub-clusters. S27,

Influence of Nitrogen Application Rates on Yield and Yield Attributes of Long Duration Varieties of Cassava (Manihot esculenta Crantz)
Suresh kumar Jabu
A field experiment was carried out at ICAR- Central Tuber Crops Research Institute (CTCRI), Sreekariyam, Thiruvananthapuram, Kerala, India to investigate the effect of different nitrogen application rates on yield and yield attributes of two long-duration cassava varieties during March, 2021 to February, 2022. The experiment was set up in Factorial Randomized Block Design (FRBD) with three replications involving two factors- two cassava varieties (Sree Pavithra and Sree Reksha) and five different nitrogen application rates (0%, 25%, 50%, 100% and 125%) of recommended nitrogen dose of 100 kg ha-1. The study revealed that the application of super optimal dose of nitrogen (125%RD of nitrogen @ 125 kg ha-1) significantly increased the yield (52.61 t ha-1) and yield attributes namely number of tubers (3.55) plant-1, average lenth of tuber (25.48 cm), average diameter of the tuber (12 cm) and average tuber yield plant-1 (4.24 kg) in cassava. Also, super optimal dose of nitrogen positivel...
