Effect of phosphorus rich compost with and without PSB and vermiculture on growth, yield and economics of maize (Zea mays L.)

Abstract

Field experiment was conducted during kharif 2013 on clay loam soil of Instructional Farm, Rajasthan
College of Agriculture, Udaipur, to study the effect of phosphorus rich compost with and without
PSB and vermiculture on growth, yield and economics of maize. The experiment was conducted in
a completely randomized block design with factorial arrangement with three replications. Treatments
included: control, 100% RDP through DAP; 100% RDP through SSP; 25% RDP through PRC + 75%
RDP through DAP; 25% RDP through PRC+PSB + 75% RDP through DAP; 25% RDP through PRC
+ vermiculture + 75% RDP through DAP; 25% RDP through PRC + PSB + vermiculture + 75% RDP
through DAP; 100% RDP through PRC; 100% RDP through PRC+PSB; 100% RDP through PRC+
vermiculture and 100% RDP through PRC + vermiculture + PSB. Among phosphorus sources, DAP,
SSP and PRC incubate with and without PBS and vermiculture, application of 25% RDP through
PRC + vermiculture + PSB + 75% RDP through DAP, significantly improved plant height, dry matter,
average cob length, no. of grains cob, weight of cob, test weight, grain yield, stover yield, net return
and B: C ratio of maize crop over other treatments. However, it was statistically at par with treatment
having 100% RDP through DAP, 100% RDP through SSP, 25% RDP through PRC + 75% RDP through
DAP, 25% RDP through PRC + vermiculture + 75% RDP through DAP, 100% RDP through PRC+PSB
and 100% RDP through PRC + vermiculture + PSB.
