Abstract

A field experiment was conducted at Palampur during 1990-91 and 1991-92 to study the effect of phosphorus
application @O, 26,52, 78 kg/ha and mulches, ie no mulch, pine needles (Pinus longifolia camara), wild sage (Lantana
camara) and polyethylene sheet on root-parameters and productivity at different growth stages of wheat (Triticum
aestivum L. emend. Fiori & Paol.) grown on a mountain Alfisol of Western Himalayas. The application of P up to 78
kg/ha significantly and positively improved the root-weight, root-volume and root-mass density as also the productivity
of wheat crop. Among the different mulching materials incorporated, the polyethylene mulch emerged superior in
improving the root growth parameter compared with the no mulch application. The root growth paramaters showed a
positive and significant association with the uptake of nutrients by wheat crop.
