Studies on seasonal variation of some important characters of guava under eastern plateau and hill region

Eastern plateau and hill regions of India are a potential zone for guava cultivation. Thirty-two varieties of guava were taken in respect of yield and physic-co-chemical characters and these were changed with different seasons.  The main objective of this research work was to find out suitable commercial cultivars and their respective seasons to grow in this particular agro- climatic zone of India. Fruit weight and fruit size were gradually increased from summer to rainy season and thereby winter season. TSS was low in rainy season, medium in winter season and high in summer season (13.7 0B, cv. Seed Drop). However, ascorbic acid content was maximum in winter season (358 mg/100g pulp, cv. Kairala Seedling) followed by summer and rainy season.  In case of pulp: seed ratio the average low value was observed in rainy season whereas summer season exhibited medium value. The maximum pulp: seed ratio was found in case of winter crops in all cultivars. The cultivar Allahabad Safeda accounted for the highest pulp: seed ratio in winter season (124.48). The maximum yield was observed in rainy season (27.39 kg/tree, cv. Allahabad Safeda) followed by winter and summer season in this ecosystem.
