Effects of polyacrylamide (PAM) and gypsum on irrigated and dryland potatoes (Solanum tuberosum L.).
… of irrigation, micronised polyacrylamide (PAM) and gypsum on the growth and yield of 'Ilam Hardy' potatoes in 2001-2002. At the final harvest, tuber yields were similar (59 500 kg ha⁻¹). Environmental factors dominated results, particularly January rainfall, which was 150% of the 16-year …
