Potato growth as influenced by planting date, spacing and NPK levels under Godavari conditions

Abstract

The field experiment was carried out during rabi season of 2018-19 and 2019-20 at College farm, COH, VR Gudem, West Godavari Distract of Andhra Pradesh. The data revealed that the highest germination and plant height, No. of branches plant-1, No. of leaves plant-1 and leaf area plant-1 (at 30, 60 and 80 DAP) and total tuber yield were recorded in November 1st planting. Respect to spacings, significantly higher growth values were noticed at 75x20 cm except tuber yield. Among NPK levels, application of 160N:80P:200K kg ha-1 was found to be superior in growth parameters as well as total tuber yield. In three way interaction of D2S2F2 and D2S1F2 were recorded the highest growth parameters and total tuber yield respectively. Plant spacing, NPK levels, their all the interaction effects were found to be non-significant on germination. Based on results, it may be concluded that D2S1F2 combination may be considered as the best treatment in terms of tuber yield.
