Response of chilli crop to NPK fertigation and PDKV grade ii micronutrients on growth and yield

Abstract

The field experiment was conducted to study the “Response of Chilli Crop to NPK Fertigation and PDKV Grade II Micronutrients” at Chilli and Vegetable Research Unit, Dr. PDKV, Akola, during Rabi season of 2023, which comes under Western Vidarbha Region of Maharashtra. The experiment comprising of twelve treatment combinations replicated three times, laid out in factorial randomized block design with three levels of fertigation (75%, 100%, 125% RDF) and four levels foliar doses of PDKV micro-Grade II (2.5, 5.0, 7.5, 10 ml/L). Plant height, number of branches, stem girth and plant spread area was recorded significantly maximum in T11 (125% RDF + 7.5 ml/L) treatment. The earliest flowering was recorded significantly maximum inT11 (125% RDF + 7.5 ml/L) at par T7 (100% RDF + 7.5 ml/L) while days required for 50% flowering and days required for first picking was recorded significantly in T11.Fruit yield per hectare (24.10 t) was recorded significantly maximum in T11. The maximum net return with higher B:C ratio (1.76) was obtained in treatment combination T11 followed by T12. From the study, it was concluded that treatment combination T7 was best and can be recommended for maximum chilli production in Western Vidarbha region.
