Effect of phosphorus sources, solubilizers and bioregulators on growth, yield and phosphorus uptake by pigeonpea (Cajanus cajan)
Year: 2001
Type: article
Abstract: An experiment was conducted during the rainy (kharit) seasons of 2001 and 2002 on clay loam soil of Udaipur, Rajasthan. Among phosphorus sources, application of rockphosphate 34% P,0$74 microns (RP 34/74) + farm- yard manure (FYM) in ratio of 1:3 + elemental sulphur (ES) at 25 kgtha significantly improved plant height, primary and secondary branchestplant, podstplant, seedslpod, seed index, yield and P uptake by pigeonpea [Cajanus cajan (L.) Millsp.] over other treatments. However, it was statistically at par with diammonium phosphate (DAP) and RP 34174 + FYM in ratio of 1 :3 phosphate-solubilizing. bacteria (PSB) at 2 kgtha. Significant improvement in pri- mary branchestplant, podstplant, seedslpod, seed index, seed yield, stover yield and P uptake by crop was re- corded by foliar spray of thiourea over water spray and 2,3,5-tri-iodobenzoic acid (TIBA). However, foliar spray of TIBA significantly reduced plant height at harvest over water spray and thiourea.
