Enhancement of phosphorus uptake, growth and yield of sweet potato (<i>Ipomoea batatas</i>) with phosphorus fertilizers

Abstract

This research was carried out to determine the best phosphorus fertilizer for improvement of sweet potato phosphorus uptake, growth and yield. The phosphorus fertilizer sources used were organic (Pacesetter), single super phosphate and crystallizer while the sweet potato variety used was Shaba. The experiment was laid out in randomized complete block design (RCBD) with three replications. Sweet potato plants from plots treated with crystallizer fertilizer at the rate of 500kg/ha had the highest phosphorus uptake and vegetative growth while control plots produced plants with highest tuberous yield. It is, therefore, recommended that crystallizer applied at the rate of 500kg/ha be used for significant phosphorous uptake which equally leads to better quality sweet potato tuber and appreciable vegetative growth. It is also recommended that the soil phosphorus be maintained at low level around 6.80mg/kg for achievement of high tuberous yield in sweet potato.

On-Farm Evaluation of Orange Fleshed Sweet Potato Varieties Under Acidic Soil of North-East Region in Bangladesh

“…Vine length differs due to the genetic makeup present in the genotypes as well as tolerance to the acidic soil environment. Results are in agreement with the findings of Kareem (2013), reported that medium sized vine length ranges from 140-180 cm gave the best yield of sweet potato. Similar results were found in literature stated that the vine length differ from 220.17-264.43 cm due to their genetic make-up of sweet potato.…”

EFFECT OF CHOPPED RICE STRAW AND FOLIAR APPLICATION OF POTASSIUM AND PHOSPHORUS ON GROWTH, YIELD AND TUBEROUS ROOT QUALITY OF SWEET POTATO (Ipomoea batatas L.) GROWING AT LATE SUMMER SEASONS UNDER CLAY SOIL CONDITIONS

Response Mechanism of Endogenous Hormones of Potential Storage Root to Phosphorus and Its Relationship With Yield and Appearance Quality of Sweetpotato

“…The content of phosphorus (P) in many soils of the world is often low or occurs in fixed forms ( Yang et al, 2014 ; Roy et al, 2016 ). P is an essential nutrient for plant growth and development, as it affects P uptake and endogenous hormone metabolism ( Shen et al, 2012 ; Ding et al, 2021 ; Zhao et al, 2021 ), and its deficiency dramatically affects the productivity of crops, such as sweetpotatoes, potatoes, chillies, soybean, rice, and so on ( Sun et al, 2019 : Kareem et al, 2020 ; He et al, 2021 ; Khanal et al, 2021 ; Nyiraneza et al, 2021 ; Yang et al, 2022 ). Previous studies have focused on the role of P in its uptake, yield, shape of the storage root, starch content, and total sugar quality of sweetpotato ( El-Deen et al, 2011 ; Wang et al, 2017 ; Villordon et al, 2018 ; Munda et al, 2019 ; Kareem et al, 2020 ).…”

These mentioned studies reported that under the conditions of a certain cultivation density, the yield is determined both by the average number of storage roots per plant and storage root weight, and between these two factors, the average number of storage roots per plant makes a greater contribution to the yield ( Si et al, 2018 ).…”
