Evaluation of the Agronomic Characters of Sweet Potato Varieties Grown at Varying Levels of Organic and Inorganic Fertilizer
Sweet potato (Solanum tuberosum), a staple tuber crop in parts of the Sudan and Guinea savanna zone of Nigeria is known for its resistance to drought, vigorous early growth and low input requirements. Increase in population which has resulted to land shortages has led to reduction in traditional methods of maintaining soil fertility. Technologies based on combinations of organic and inorganic s...
متن کاملNematode numbers and crop yield in a fenamiphos-treated sweet corn-sweet potato-vetch cropping system.
Nematode population densities and yield of sweet corn and sweet potato as affected by the nematicide fenamiphos, in a sweet corn-sweet potato-vetch cropping system, were determined in a 5-year test (1981-85). Sweet potato was the best host of Meloidogyne incognita of these three crops. Fenamiphos 15G (6.7 kg a.i./ha) incorporated broadcast in the top 15 cm of the soil layer before planting of e...
متن کاملSeasonal Influence on Yield and Yield Contributing Characters of Lablab Bean [Lablab purpureus (L.) Sweet]
A study was conducted to evaluate the seasonal influence on yield and yield contributing characters of four lablab bean genotypes: IPSA Seam-1, IPSA Seam-2, BU Seam-3 and JER during September 2000 to December 2001 covering one main season (winter) and two off-seasons (early summer and late summer). Compared to off-seasons, all the genotypes performed better for all the parameters during winter....
متن کاملDetection of sweet potato virus C, sweet potato virus 2 and sweet potato feathery mottle virus in Portugal.
Field sweet potato plants showing virus-like symptoms, as stunting, leaf distortion, mosaic and chlorosis, were collected in southwest Portugal and tested for the presence of four potyviruses, sweet potato virus C (SPVC), sweet potato virus 2 (SPV2), sweet potato feathery mottle virus (SPFMV), sweet potato virus G (SPVG), and the crinivirus sweet potato chlorotic stunt virus (SPCSV). DsRNA frac...
