Abstract
The present investigation was undertaken to evaluate the “ Response of potato (Solanum tuberosum L.) to zinc application” at Vegetable Research Centre of G.B. Pant University of Agriculture & Technology, Pantnagar, Udham Singh Nagar, (Uttarakhand) during rabi season of 2016-2017. The experiment was laid out in randomized block design with three replication and ten treatments. During the study, observation on per cent emerge nce, leaf area index at 30 and 45 DAP, stem diameter at 45 DAP, plant height at 30 and 45 DAP, haulm weight per plot, Total number of tubers per hill, weight of tubers per hill, total tuber yield per plot, total tuber yield per hectare, harvest index, dry matter content, starch content, specific gravity of tubers, nitrogen, phosphorus and potash uptake by haulm, tuber, plant, available zinc content of soil before planting, available zinc content of soil after harvesting, available zinc content in potato plant at de-haulming, available zinc content in potato tubers were recorded. Besides this, to assess the profitability of treatments, cost of cultivation, net profit and benefit: cost ratio were also worked out. The findings of present investigation revealed that the performance of potato crop was significantly influenced by different zinc application. Among all treatments, treatment T5(RDF of NPK + 6.0 kg Zn at the time of planting) was found best with respect to overall plant growth, yield and quality parameters with total tuber yield (33.9 t/ha) , net profit (`273087.00), benefit: cost ratio (2.3). Based on overall performance, it could be concluded that under prevalent climatic conditions of Uttarakhand tarai region, application of zinc @ 6 kg/ha at the time of planting along with 160:100:120 kg N:P2O5:K2O can be recommended to get maximum tuber yield and higher net returns from the potato crop. Hence, recommended for commercial cultivation, provided all other scientific management practices are followed.
