Growth Parameters and Yield Evaluation of Tropical and Temperate Sweetpotato Genotypes Under Acid Soil Conditions

Abstract

Sweetpotato (Ipomoea batatas L. Lam) is an important tuber crop with a wide range of eco-physiological adaptability. The analysis of diversified crops could be an approach to explore sweetpotato productivity under acid soil conditions. To observe the yield performance of nine sweetpotato genotypes with temperate origin (Japanese) and tropical origin (Bangladeshi), the experiment was conducted in the acidic soil and tropical environment of Sylhet, Bangladesh. The experiment was laid out in Randomised Complete Block Design with three replications. For the growth studies data were recorded at 30 days after planting (DAP) and morphological and yield parameters were recorded at final harvest. Results showed that the morphological ______________________________________

Evaluation of Growth Performance and Economic Return Analysis of Bathua (Chenopodium album) Genotypes

“…Our test site's soil in Sylhet has a pH of 4.80, making it mildly acidic in nature. Usually, the acid soil with lowered pH (4.8 to 5.7) reduces the yield losses up to 30%, have been reported earlier in onion (Sarker et al, 2022), okra (Sumi et al, 2022) and sweet potato (Paul et al, 2021). The screening of cultivated crop genotypes for low pH tolerance would provide a better understanding of the crop adaptation and the management (Chy et al, 2022;Roy et al, 2016).…”
