e0“Field studies were conducted on a Hubbard loamy sand (sandy, mixed, frigid Entic Hapludoll) during 1996 and 1997 at Becker, Minn., to evaluate the effect of a polyolefin-coated urea (POCU) fertilizer (Meister, Chisso Co., Japan) on yield and quality of irrigated `Russet Burbank' potatoes ( Solanum tuberosum L.)”
e1“Total and marketable yields averaged, respectively, 3.9 and 3.3 Mg·ha -1 higher with POCU than with urea”

Other claims from this paper (9)
- Intervention effect Total yield averaged 3.9 Mg·ha-1 higher with POCU than with urea.
- Intervention effect Total yield was not affected by N application rate, regardless of N source.
- Intervention effect Marketable yield increased linearly with N rate.
- Intervention effect Yield of marketable tubers larger than 170 g increased linearly with N rate in both years.
- Intervention effect Gross return was 10% higher with POCU than with urea.
- Association Net return increased by $3.13 per kg of urea-N applied.
- Intervention effect Net return showed no significant change across POCU application rates.
- Association Estimated net return showed a significant source × N rate interaction.
- Association Yields were higher in 1996 than in 1997, attributed to cooler temperatures and poor tuber set in 1997.
