Abstract
A two years field experiment was conducted at the Vegetable Research Farm, ANDUA&T, Kumarganj, Ayodhya (U.P.), under the All India Coordinated Research Project (AICRP) on Potato during the Rabi (winter) seasons of 2022-23 and 2023-24. The site is located within the agro-climatic zone of the Middle Gangetic Plain, which is characterized by fertile soils and a favourable climate for potato cultivation. The experiment was laid out using a Randomized Block Design (RBD) to ensure statistical reliability and reduce variability, comprising 10 distinct treatment combinations, each replicated three times. This setup aimed to evaluate the performance and interaction of treatments under field conditions. The study focused on assessing yield and soil properties for optimizing potato production in this specific agro-ecological region. The data collected across two consecutive growing seasons provided robust insights into seasonal effects and treatment consistency. The results showed that the highest tuber yield (36.14 t ha-1), marketable tuber yield (36.13 t ha-1), fresh weight of haulm (15.41 t ha-1) and dry weight of haulm (3.14 t ha-1) in T6 and lowest tuber yield (19.92 t ha-1), marketable tuber yield (19.90 t ha-1), fresh weight of haulm (8.91 t ha-1) and dry weight of haulm (2.01) in T10.
