Abstract:
In Chhattisgarh plains potato crop grown as a rabi crop. The crop requires high water for its proper growth and good yield. On other hand, excess water reduces yield. Low and high available soil moisture both affect badly the crops. The present investigation conducted to evaluate of different irrigation regimes and genotypes for potato growth and yield. At 75 DAP and 90 DAP, the various yield and yield attributing characters were significantly affected by the different irrigation regimes except plant emergence at 75 DAP and number of shoots plant-1 at 90 DAP. On other hand, potato genotypes were differing non-significantly. Plant emergence at 90 DAP, plant height (cm), number of shoots plant-1 at 75 DAP, number of compound leaves plant-1, fresh and dry weight of shoots plant-1 (g), total tuber yield (t ha-1) and marketable tuber yield (t ha-1) significantly affected by the different irrigation regimes and potato genotypes. The water deficit condition imposed by the irrigation at 25 mm CPE reported for the maximum total tuber yield (21.89 t ha-1 and 25.07 t ha-1) and marketable tuber yield (19.75 t ha-1 and 23.74 t ha-1) for 75 DAP and 90 DAP, respectively. The potato genotype AICRP-P-38 gave the highest total tuber yield (25.97 t ha-1 and 29.15 t ha-1) and marketable tuber yield (23.76 t ha-1 and 27.42 t ha-1) for 75 DAP and 90 DAP, respectively.
