Abstract
The present study, entitled “Standardization of Aeroponic Technology for Mini Tuber Production in Potato (Solanum tuberosum L.)” was conducted in the Division of Plant Physiology, Sher-e-Kashmir University of Agricultural Sciences and Technology of Jammu. The experiment was conducted during winter and spring seasonsin 2022-23. Two varieties Kufri Badshah and Kufri Jyotiwere taken as experimental material. Potato tubers were sown in net pots containing growing media and seedlings were transplanted at five leaves stage in the aeroponics system. The experiment was laid out in Completely Randomized Design with two treatments viz, T1(cocopeat 100%) and T2(cocopeat +vermiculite+ perlite+ vermicompost) in ratio (2:1:1:2) and after two weeks of transplanting data was recorded at three different stages of crop growth (20 DAT, 45 DAT and 80 DAT). In relation to morphological responses, the highest plant height was recorded in T2(61.26 and 59.25 cm) and lowest T1(57.63 and 56.355 cm) in both varieties. Similarly, number of leaves per plant, number of branches per plant, days to tuberization, plant survival rate, as well as chlorophyll content by SPAD were also recorded significantly higher in T2 (63.83,21.0,52.33,99.90% and 55.83 ) respectively the lowest were recorded inT1 (40.88,18.2,54.66,99.50% and 50.77) respectively in both the varieties.Where as, shoot length and root-shoot ratio were significantly higher in T2(30.11cm,6.15) in kufrijyoti and lowest in T1 (28.63cm,3.7) As far as physical and biochemical parameters Nutrient use efficiency, water use efficiency, was noticed highest in T2(0.59,0.45 and10.0,7.5,) and lowest in T1(0.46,0.33and 8.0,6.25)respectively in both varieties.Total chlorophyll content, starch content as well as relative water content were recorded maximum in T2(2.70,2.28mgg -1 FW,9.58,8.21%,83.67,79.24(RWC%)respectively and minimum T1(2.16,2.06mg g -1 FW,9.50%8.10%,82.04.77.52(RWC%)respectively in both varieties. Similarly, biochemical parameters, i.e tuber size, number of mini tubers per plant, average mini tubers weight and yield of mini tubers per plant were also recorded significantly higher in T2 (2.30,1.46cm,11.6,7.33,24.9,12.2g,190 and 162g)respectively. and lowest were recorded in T1(1.66,1.26cm,8.3.6.3,19.7,11.3g,182.6 and 152.0g)respectively in both varieties.
The results clearly indicated that treatment T2: coco peat + perlite + vermiculite + vermicompost in the ratio of 2:1:1:2 was the most promising treatment for improving the morphological, physiological, biochemical parameters, yield, and quality of both potato varieties when compared to other treatments
