Effect of NPK on Vegetative Growth and Yield of Desiree and Kufri Sindhuri Potato / Adhikari, R.C. in Nepal Agriculture Research Journal, Vol. 9 (2009)
[article]
Title : Effect of NPK on Vegetative Growth and Yield of Desiree and Kufri Sindhuri Potato Material Type: printed text Authors: Adhikari, R.C., Author Publication Date: 2009 Article on page: 61-68 p Languages : English (eng) Keywords: Desiree, fresh weight, Kufri Sindhuri, nutrients, tuber yield Abstract: A field experiment was carried out to assess the effect of NPK on vegetative
growth and yield of potato cultivars; Kufri Sindhuri and Desiree at different
nutrient levels (0:0:0, 50:50:50, 100:50:50, 100:75:50, 100:75:100,
100:100:100 and 150:100:100 N, P205 and k20 kg ha-1) in sandy loam soils at
Rampur, Chitwan, Nepal during 1999/2000. The experiment was laid out in a
split plot design with 4 replications. Plant height, number of stems, fresh
weight of stem and leaves were recorded at 15 days interval during crop
growth period and tuber yield at maturity stage. Kufri Sindhuri was taller
than Desiree at all the stages of plant growth. Increasing levels of NPK
increased the plant height by 15-42 percent. The levels of NPK imparted to a
significant effect on fresh weight of leaves and stems at each successive
stages of crop growth. Kufri Sindhuri responded nitrogen up to 150 kg ha-1
while Desiree yielded higher at 100:100:100 kg NPK ha-1. The yield increase
of potato tuber was associated with increase in the plantLink for e-copy: http://elibrary.narc.gov.np/?r=9

Title : Performance of Different Size True Potato Seed Seedling Tubers at Khumaltar Material Type: printed text Authors: Adhikari, R.C., Author Publication Date: 2005 Article on page: 28-34 p Languages : English (eng) Keywords: Desiree, seedling tuber, tuber size, yield Abstract: A field study was carried out at Khumaltar-Lalitpur, during 2002-2004 to evaluate and compare
the performance of different sizes of seedling tubers (1-5 g, 5-10 g, 10-20 g and 20-40 g) of true
potato seed (TPS) with whole and half cut seed tubers of Desiree of 20-40 g size at 60- 25-cm
spacing. Percent emergence, plant height, ground cover by foliage, stems/plant, number of tubers
per plant, marketable and total yields were significantly increased with the increase in seedling
tubers weight as compared to whole and half cut seed tubers of Desiree. Late blight
(Phytophthora infestans L.) disease was quite low in the TPS crops than Desiree. Both whole
and half cut seed tubers of Desiree produced significantly higher average per tuber weight.
Uniformity of the tubers harvested from different sizes of seedling tubers was statistically
similar and tubers from Desiree were statistically uniform as compared to seedling tubers. The
three years result suggests that more than 1 g size seedling tubers can be successfully used for
potato production as from the seed tubers of any standard variety.Link for e-copy: http://elibrary.narc.gov.np/?r=58

[article]
Title : Use of Chemical Fertilizers on Potatoes in Sandy Loam Soil under Humid Sub-Tropical Condition of Chitwan Material Type: printed text Authors: Adhikari, R.C., Author ; Sharma, Mohadatta, Author Publication Date: 2004 Article on page: 23-26 p Languages : English (eng) Keywords: Desiree, Kufri Sinduri, nutrients, potato, tuber yield Abstract: An experiment was conducted at Rampur, Chitwan to study the effects of N, P2O5 and K2O on
tuber yield, quality and leaf nutrient status of potato cv. Kufri Sinduri and Desiree. The highest
potato tuber yields (35.7 and 21.1 t ha -1) were obtained with 150:100:100 and 100:100:100 of
N:P2O5:K2O kg ha-1 respectively of Kufri Sinduri and Desiree. The optimum dose of N, P2O5 and
K2O was 100:50:50 kg ha-1 for both cultivars. Regression of N, P2O5 and K2O doses on Kufri
Sinduri and Desiree explained 78 and 31% variation, respectively, in the tuber yield. Leaf N alone
accounted for maximum variation (76% and 43% by linear in Kufri Sinduri and Desiree,
respectively). Leaf N, P and K, respectively 5.04, 0.29 and 3.97% dry matter was critical for potato
production under humid sub-tropical condition of Chitwan. Present findings suggest that Nitrogen,
Phosphorous and Potassium fertilizers management should be based on leaf analysis for balanced
application of mineral nutrients in potato crops.Link for e-copy: http://elibrary.narc.gov.np/?r=74
