Abstract
An investigation was carried out during three consecutive years from 2016-17 to 2018-19 at farm of B.P.S. Agricultural college, Purnea on Mango cv. Amrapali to study the effect of conservation practice of mulch with irrigation and fertilizer levels on yield and soil parameter, fruit yield and its qualities of mango grown in kosi zone of Bihar. The experiment was laid out in split split plot design with three replications. Experimental findings revealed that conservation practices as mulch significantly increased fruit set, fruit retention, fruit yield and fruit quality. Among different irrigation levels and fertilizer doses maximum fruit yield (23.24 ton/ha) was obtained under conservation practice with 75% recommended irrigation along with 100% RDF which was at par with conservation practice with 75% recommended irrigation along with 75% RDF. Conservation treatment also showed maximum TSS (23.69° Brix) with maximum (0.39%) acidity of fruit. Observations also revealed that conservation practices as mulching significantly increased the soil moisture content, organic carbon %, available soil N, P and K, along with increase soil microbial population. Among the different fertilizer levels highest organic carbon %, available soil N, P and K, as well as soil microbial population were observed with 100% RDF, however only organic carbon and available soil P were at par with 75% RDF.
