Combined effect of NPK levels and foliar nutritional compounds on growth and yield parameters of potato plants (Solanum tuberosum L.)
Year: 2012
Type: article
Abstract: Field experiment was conducted to study the effect of NPK levels and foliar nutritional compounds on growth yield, chemical constituents and nutrients content of potato plants grown in newly reclaimed soil. The obtained results could be summarized as follows: Increasing the NPK levels significantly increased all the growth, and yield parameters (except for number of aerial stem, plant), photosynthetic pigments, chemical constituents of potato tuber at harvest, and macro and micronutrients in potato shoots and tubers. The highest values of the mentioned parameters were obtained by using the highest NPK (120:80:100) as compared with the other two NPK levels (Medium: 102:68:85 and low: 90: 60: 75). Foliar application with folifertile, Byfolane and fetrilon combi significantly increased growth and yield parameters, photosynthetic pigments, chemical constituents and nutrients content of shoots and tubers as compared with the control treatment. The highest effective treatment in this respect was folifertile followed by Byfolane and fetrilon combi in decreasing order. The interaction between NPK levels and foliar nutritional compounds significantly affected leaves number (LN)/plant, chl. b and chl. a + b, tuber yield, mono sugars, carbohydrate and L-ascorbic acid as well as p, Mn and Cu concentration in shoots, and N and Fe in tubers. The interaction did not significantly affect the other studied parameters.
Key words: Foliar compounds, nutrients content, potato NPK chemical constituents, interactions.
