Impact of organic and inorganic fertilizers on growth, yield and economics of garlic (Allium sativum L.)

Abstract

A field experiment was carried out at Research Farm, College of Agriculture, Indore (Madhya Pradesh) during winter season 2020-21 to study the impact of organic and inorganic fertilizers on growth, yield and quality of garlic. The experiment comprising of organic-cum-inorganic sources of nutrients was laid out in randomized block design with three replications. Results revealed that application of 50% RDF along with 2.5 t VC ha-1 + 1.5 t PM ha-1 brought about maximum growth and yield-attributing parameters ( plant height 87.4 cm, leaves 10.8 / plant, leaf length 51.3 cm, leaf width 2.10 cm, LAI 2.42, neck thickness 1.55 cm, bulb weight 42.90 g, bulb diameter 5.78 cm and cloves 27.5/ bulb) as well as bulb yield ( 103.54 q ha-1), net income ( Rs. 230630 ha-1) and B: C ratio ( 3.88). The second best treatment was 50 % RDF + 5 t VC ha-1 with 98.24 q ha-1 yield, and net income of Rs. 214980 ha¬-1. Similarly, the maximum value of TSS (40.15 oBrix) was recorded under the 50 % RDF + 2.5 t VC + VC + 1.5 t PM ha-1. The overall trend indicated that combined application of VC and PM was found superior than their separate application along with RDF.
