73. Performance of potato varieties under the climatic conditions of Abbottabad Hazara
Abstract
An experiment “Performance of potato varieties under the agro-climatic conditions of Abbottabad Hazara” was conducted in Spring, 2016 at the Hazara Agriculture Research Station Abbottabad. The experiment was laid out in Randomized Complete Block Design. Total treatments were consisted of ten varieties i.e. Rock, Red Sum, Aurea, Nazca, Focus, Eldorado, Desiree, Elbeida, Red Valentine and Toureg and all treatments were replicated three times. Sprouting percentage was found maximum in Red Valentine (98.3), followed by Red Sum (97.5), Eldorado (95.8) and Aurea (92.5). The maximum number of stem plant-1 was noted in Red Sum (5), followed by Rock (5), Focus (5), Nazca, Eldorado and Red Valentine (4 number in each). Red Sum and Red Valentine got least disease and less number of small tubers. The highest number of medium size tubers plot-1 were recorded in Red Valentine (39), followed by Red Sum (35). Red Sum and Red Valentine produced highest number of large size tubers plot-1(27 and 25). Eldorado had maximum total number of tubers plot-1(170). The smallest weight of small tuber plot-1 was noted in variety Red Valentine (2.2 kg), followed by Red Sum and Focus with 2.3 and 2.8 kg respectively. While maximum weight of medium tubers plot-1and maximum total weight of tubers plot-1was recorded in variety Red Valentine (8.2 and 18.8 kg), followed by Red Sum7 and 18.7 kg respectively. The highest weight of large tubers plot-1 was recorded in Red Sum (9.4 kg) and the least moisture was recorded in variety Red Sum(73.7%), followed by Red Valentine (74.3%) and Toureg (77.7%), while highest dry matter was recorded in variety Red Sum(26.3%), followed by Red Valentine (25.7%) and Toureg. The maximum yield (ton/ha) was recorded in Red Valentine (25), followed by Red Sum (24.9). It is concluded that variety Red Sum and Red Valentine showed superior results in the agro-climatic conditions of Abbottabad Hazara.
