Studies on effect of fertigation level and response of mulching on growth and yield parameters of papaya (Carica papaya L.) under Chhattisgarh plains

Abstract

A field experiment was conducted to “studies on effect of fertigation and response of mulching on growth and yield parameters of papaya (Carica papaya L.) under Chhattisgarh plains.” during the year 2015-16 in winter season at Horticulture Instructional-cum- Research Farm, Precision Farming Development Centre (PFDC) IGKV, Raipur (Chhattisgarh). The experiment was laid out in a randomized block design with twelve treatments combinations and three replications. The experimental plots were treated with three fertigation levels 60, 80, and 100% RDF and different mulching materials consisting of silver plastic, organic and without mulch. The plant height, petiole length, stem girth, initiation of flowering, number of fruits, fruit weight, yield plant-1 and yield ha-1 increased with fertigation level and mulching. Highest fruit yield plant-1was recorded in plastic mulch with 100% RDF (28.29kg) followed by (26.31kg) in plastic mulch with 80% RDF and lowest fruit yield was recorded in control treatment (14.94kg). Under fertigation experiment highest fruit yield ha-1 was recorded in 100% RDF using plastic mulch, vermiwash and neem seed extract (87.31MT) followed by 80% RDF using plastic mulch, vermiwash and neem seed extract (82.53MT) and lowest fruit yield ha-1 was found in conventional irrigation system
