“…4.). Our present findings were in agreement with Mahmud (2012) and Begum et al (2011), who reported similar decreasing trend of RGR in potato varieties and the highest RGR value was calculated at 30-40 DAP. According to Abbas (2011), the variation in the RGR in the respective varieties might be due to difference in temperature or weather during the crop seasons.…”

An experiment with four potato varieties, namely Asterix, Cardinal, Diamant and Granola was conducted at the Horticulture Research Field of Bangabandhu Sheikh Mujibur Rahman Agricultural University, Gazipur during November 2013 to February 2014 to observe the behaviour of growth parameters and yield potentiality of potato. Final harvest of tuber was done at 90 DAP. LAI, CGR, RGR and NAR were not significantly influenced by the varieties. Irrespective of varieties, LAI increased progressively with time reaching a peak at 60 DAP and thereafter declined. Granola maintained the lower LAI throughout all growth stages. Numerically, the maximum CGR (19.99 g m-2 day-1) was found in Asterix at 50-60 DAP and the highest RGR (107.33 mg g-1 day-1) as well as NAR (9.54 g m-2 day-1) was recorded in Cardinal at 30-40 DAP. At 60-70 DAP, Cardinal recorded the highest TBR (84.35 g m-2 day-1) while Asterix, the highest TGR (18.54 g m-2 day-1) but Granola gave the lowest values of TBR (65.21 g m-2 day-1) and TGR (14.92 g m-2 day-1) at this growth stage. At all growth stages except 30 and 40 DAP, Diamant showed the best performance in SLA while Granola showed the lowest. The maximum yield was produced by Asterix (31.46 t/ha) closely followed by Diamant (29.91 t/ha) and Cardinal (27.27 t/ha) while the lowest yield was produced by Granola (24.82 t/ha). Granola showed the capacity of producing 95% or more of its final yield within 60 to 70 DAP. Therefore, Granola can be used as an early variety for potato cultivation.Bangladesh J. Agril.

Aim: To assess the performance of winter potato (Solanum tuberosum L.) variety Kufri Megha, under real time based irrigation scheduling, i.e., ratio of depth of irrigation water to cumulative pan evaporation in mid hills of Meghalaya during winter season of 2016-17. Methodology: A field trial with three different irrigation scheduling as main-treatments, viz., IW: CPE- 0.75 (I1), IW: CPE- 1.00 (I2) and IW: CPE- 1.25 (I3), four different dates of planting, viz., 1st November (D1), 11th November (D2), 21st November (D3) and 1st December (D4) was laid out and replicated thrice. Irrigation was provided with a micro sprinkler irrigation system and was laid out in split plot design. Results: The plants planted on 11th November and irrigation scheduled at IW: CPE-1.25 recorded higher values for plant height (cm), number of branches per plant, leaf area index, dry matter accumulation per plant, net assimilation ratio, crop growth rate, relative growth rate, tuber yield (t ha-1), haulm yield (t ha-1), harvest index (%), water use efficiency and benefit cost ratio over other treatments. Interpretation: It can be recommended that by following climatological approach of cumulative pan evaporation for irrigation scheduling in potato using micro sprinkler method of irrigation, the crop water requirement could be met during lean period to avoid moisture stress in plants coupled with planting at the right climatic conditions.

“…Depending on the irrigation system, water consumption efficiency in potato varies from 5.4 to 12 kg m −3 16 , 24 . Drip irrigation is one of the most effective methods and ranged from 6.3 to 8.6 kg m −3 (Sharma 2007) 25 .…”

“…Xu et al (2010) 32 achieved higher yields using the same irrigation system (40–48 t ha −1 ), and potato tuber weight was reduced under the slight water stress. Potato reacts to stress when soil water tension exceeds 20 kPa 24 . In a study by Amer et al (2016) 33 potato tuber yield also decreased with the application of excessive irrigation, resulting in greater stress, increased vegetative growth and potential leaching of nutrients from the root zone.…”

This study aims to determine the effects of differences in variety and irrigations levels on potato yield (appropriate humidity, temperature, shading the plants from the sun if necessary) on potato yield in greenhouse conditions. Functions of potato production with respect to water use were developed for five dates of measurements of plant growth, in relation to the various vegetation phases. On the basis of potato vegetation phases, the potato water demand was determined. An experiment was conducted using the randomized sub-block method. The first order factor were the two varieties of potato that were grown under drip irrigation with three water regimes as a second factor experiment: level 1 (pF 2.7), level 2 (pF 2.5) and level 3 (pF 2.2). The variety had a significant effect on the weight of potato tubers. The irrigation level had only a significant effect on the total potato biomass. The potato harvest date had a significant effect on both of the examined treatments. The growth dynamics of the aboveground part and potato tubers were the highest in conditions of constant level 1. Regardless of the variety studied, on level 3 caused a reduction in potato biomass production.The highest water consumption was observed during the tuber potato growth period to flowering. The values were varied from 0.39 l/pot day level 1 (in both investigated cultivars) to 0.99 l/ pot/day (humidity level 3 for Julinka cultivar) in July. The most intensive increase in water consumption was observed at the level 3. The average W index of the average daily water dose calculated for Denar cultivar amounted 0.40 l day−1 in the first period (O1) to 0.79 l day−1 in the fifth period (O5) and for Julinka cultivar 0.49 l day−1 (O1) to 0.92 l day−1 (O5). Stress due to water shortage and/or excessive levels of water in the soil negatively influenced the yield of potato tuber. Potato varieties reacted differently to soil water content.
