Growth and yield performance of hybrid hot pepper, chilli (Capsicum annuum L.) as influenced by fertigation and polyethylene mulching

Abstract

A field experiment was conducted at Bengaluru during 2015 to study the effect of fertigation on performance of hybrid chilli (Capsicum annuum L.). The trial included nine treatments comprising varying rates and sources of fertilizers, tested with or without mulching. Application of recommended dose of fertilizer (180:120:180 kg NPK/ha) through fertigation using water-soluble fertilizers resulted in higher values for plant height (104.27 cm), number of branches per plant (16.71), leaf area per plant (89.44 dm2 ), dry matter per plant (185.49 g), number of fruits per plant (142.7), fruit length (11.13 cm), fruit girth (4.75 cm), fruit weight (1.29 g), yield per plant (184.11 g) and fruit yield (5.03 t/ha) which remained on par with same amount of fertilizer applied using conventional means along with polyethylene mulching. In general, treatments that received fertilizers through fertigation took less number of days to flowering over conventional soil-application of fertilizers. All fertigation treatments recorded higher dry-chilli fruit yield over the conventional soil-application of fertilizers, to a tune of 27.87% to 52.4% over the control.
