Effect of Crop Geometry on Growth, Yield and Quality of Sweet Potato (Ipomoea batatas L.) Genotypes

Field experiments were conducted in 2018 and 2019 at the National Potato Research Programme (NPRP), Lalitpur (1360 masl), Nepal, to determine effect of crop geometry on growth, yield, quality sweet potato genotypes. The experiment was laid out sandy loam soil a factorial randomized complete block design (RCBD) with three replications comprised total twelve treatment combinations four (60cm×25 cm, 60cm×30 70cm×25 70cm×30 cm) genotypes (CIP 440015, CIP 440267 Local White). Among different geometries evaluated, cm plant spacing White genotype found statistically superior enhance marketable tuberous root weight per (0.572 0.541 kg), diameter (62.59 61.0 mm), shoot fresh (509 524 g), yield (616 620 g). genotype, yielded higher among reducing sugar content influenced significantly by pooled mean showed highest (15.48 17.26 %) closer 60 × 25 respectively lowest (11.54 440015. genotypes, other hand, high ß carotene content, whereas had negligible amount (0.35 mg/100g). On hectare level, our result that density 66,666 plants ha-1 (60 could give unit area due greater biomass. Our findings suggest can have considerable impact production. As result, potatoes be wide or narrow depending needs available study similar situation.
