Abstract:
The field experiment was carried out to evaluate the effect of mulching and fertigation on growth, yield and quality of guava var. L-49 under high density planting system during 2020-21 at Horticultural College and Research Institute, Periyakulam. Four levels of fertigation dose (50%, 75%, 100% through fertigation, 100% RDF soil application) in combination with four levels of mulching (black polythene mulch, weed mat, paddy straw and no mulch) was evaluated laid out in split plot design and replicated twice. The result indicated that fertigation and mulching significantly influenced the growth, yield and quality parameters of guava. Among the treatment combination, 100% RDF through fertigation with paddy straw mulch reported maximum growth parameters like plant height, stem girth, canopy spread. Maximum values of yield parameters viz. number of fruits per plant, fruit weight, fruit length, yield per plant and quality parameters like TSS, ascorbic acid and total sugar were observed in 75% RDF through fertigation with paddy straw mulch on comparison with other treatments. Hence, 75% RDF through fertigation with paddy straw considered as environment friendly practise which saves fertilizer requirement for guava cultivation under high density planting system.
