Nutrient management studies on vegetative growth performance of dragon fruits

Abstract

An experiment entitled “Nutrient management studies on vegetative growth performance of dragon fruit plants” was carried out during the year2018-19 at Experimental Farm, Department of Fruit Science, Faculty of Horticulture, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola with objective to study the effect of N.P.K. levels on vegetative growth of Dragon fruit and to find out the suitable concentration of N.P.K. for better vegetative growth of Dragon fruit under Akola condition. The experiment was laid out in Randomized Block design with ten treatments viz., T1 (200:50 NP) g/plant, T2 (200:37.5 NP) g/plant, T3 (200:50 NK) g/plant, T4 (200:37.5 NK) g/plant, T5 (150:50 NP) g/plant, T6 (150:37.5 NP) g/plant, T7 (150:50 Nk) g/plant, T8 (150:37.5 NK) g/plant, T9 (200:50:50 NPK) g/plant, T10 (150:37.5:37.5 NPK) g/plant. All treatment were replicated three times. The results of present investigation indicated that, the maximum plant height, number of branches, main stem circumference, plant canopy north to south, plant canopy east to west, number of sprouting, new shoots height was recorded in treatment T9 (200:50:50 N:P:K g/plant). The available nitrogen, phosphorous, potassium content in soil were maximum under treatment T9 (200:50:50 N:P:K g/plant).
