The Effect of Foliar an-Nebras Colloidal Fertilizer at Different Growth Stages on Growth, Yield and Yield Components of Barley (Hordeum vulgare L.)

Abstract

A field experiment was conducted during the growing season of 2013 – 2014 to study the effect of foliar fertilization containing macro and micro elements at different growth stages on growth, yield and yield component of Barley. Randomized complete block design was used at three replicates. The experiment included three foliar fertilizer concentrations, C0 (control) , C2 (0.005 L.L -1water), C3 (0.01 L.L-1 water). Growth stages were G1 (tillering), G2 (Tillering and stem elongation), G3 (Tillering, stem elongation and booting). Results showed that all foliar concentration and growth stages and their interaction affected significantly on all study parameter, Applications of C2 gave the highest (plant height , No of tiller . m-2, No of spikes. m-2, weight of 1000 grain and grain yield which were 71.63 cm, 388.8 tiller. m-2 357 spike.m-2, 41.6 gm and 3.94 t.ha-1). while C0 gave the highest value of number of grain. spike-1 (39.60) grain. spike-1. The treatment G3 gave the highest plant height, number of tiller .m-2, number of spikes. m- 2 and grain yield which were 72.6 cm, 366.7 tiller. m-2 , 339.1 spike. m-2 and 4.12t. ha-1 respectively while G2 gave the highest weight of 1000 grain (39.22 gm). Interaction between (G2* G3 ) gave the highest number of tiller . m-2, Number of spikes. m-2 weight of 1000 grain and grain yield (428.7 tiller . m-2, 398.3 spike. m-2 , 43.26 gm and 4.83 t. ha-1 respectively, while G3 * G2 gave the highest plant height (75.40 cm).
