Growth and Yield of Carrot (Daucuscarota L.) as Affected by Different Irrigation Frequency, Organic Soil Amendments and Inorganic Fertilizer

Abstract

Growth and yield of carrots exposed to different irrigation frequency, organic soil amendments and inorganic fertilizer was investigated using 2x4 factorial experiment designs to find out the effects of those variables. The frequency of irrigation were two (F1) and  four days intervals (F2), and the different organic soil amendments were the mushroom spent, chicken dung and native sunflower leaves. The inorganic fertilizer was the ammonium phosphate, urea and muriate of potash (S0). Statistical analysis showed that he length of leaves at 31, 38, 52, 66, 80 and 88 days after emergence and irrigated 2 days interval was highly significant, but the number of leaves, diameter of root, and texture of root were not significant. The root length, weight and number of marketable root, were significantly affected by irrigation at two days interval with the highest yield of 22.06 t/ha, and irrigation at four days interval resulted to lowest yield of 13.84 tons/ha. While no significant interaction were noted on the effects of the two factors on the length of foliage at different days after sowing. https://doi.org/10.26803/ijhss.11.4.2
