Abstract
Chilli is one of the most valuable commercial vegetable crops
grown throughout the country. It is grown in both rainfed and irrigated
conditions, however in traditional growing regions of Karnataka, it is
mainly grown as a rainfed crop. The study was carried out in PFDC
Centre, Division of Horticulture, UAS, GKVK in 2012-13 to determine the
effect of different levels of fertigation and mulching on growth, yield and
quality of chilli (Capsicum annuum L.) var. Arka Lohit with 8 treatments
in combination of 3 fertigation and 2 mulching levels. The treatment T5 [
120% RDF (water soluble) + drip fertigation + 30 micron black polythene
mulch] recorded maximum plant height (110.60 cm), number of
branches(18.10), plant spread (4241.70 cm2), number of flowers (231.16),
fruit set percentage (79.12), fruit length (9.62 cm),number of fruits per
plant (185.10), fruit yield per plant (573.81 g), fruit yield per
hectare(16.98 t), quality attributes like number of seeds per fruit (75.74),
dry fruit weight (22.74 per cent), ascorbic acid (131.62 mg/100 g of fresh
weight,) TSS (7.4 °Brix). From this investigations we could conclude that,
120 per cent of recommended dosage (180 N : 90 P2O5 : 90 K2O Kg ha-1)
of fertilizers in the form of water soluble fertilizer along with drip
irrigation + 30 micron black polythene mulch is ideal for the maximum
growth, yield and quality attributes in chilli var. Arka Lohit.
