Impact of integrated nutrient management on growth and yield of Chinese potato (Coleus rotundifolius L.)

Abstract

A field experiment was conducted at College of Horticulture, Venkataramannagudem, West Godavari District, Andhra Pradesh during Rabi 2023-24 to study the effect of Integrated Nutrient Management on growth and yield of chinese potato. The statistical design used for this experiment was Randomised Block Design (RBD) with 16 treatment combinations and replicated twice. The results revealed that the treatment combination of 75% RDN (Recommended dose of nitrogen) + 25% RDN FYM + vermicompost + biofertilizers + biochar (T13) showed the highest vine length (56.00 cm), number of branches per plant (10.30), leaf area (23.50 cm2), number of big, medium and small sized tubers (9.47, 18.16 and 41.09), total number of tubers (56.79), length of big, medium and small sized (6.79 cm, 4.39 cm and 3.79 cm), diameter of big sized (5.44 cm), medium sized (3.92 cm) and small sized tubers (1.51 cm), average weight of big sized (84.23 g), medium sized (84.23 g) and small sized tubers (26.37 g) and tuber yield (0.53 kg/plant).
