PLANTING DENSITY ON YIELD POTENTIAL OF BARLEY Statistics ( hordeum distichon l.) CENTENNIAL WITH LATE SEEDING UPLAND CONDITIONS

Abstract

Centenariol statistical barley, has been driving for two seasons to reach full fitness with high performance capability, being careful not to change the characteristics of grain and without losing their avoidance behavior to factors limiting productivity growth. The study involved the second stage comparing 4 population densities in late planting conditions and dry. The experiment was installed in BCA with 3 replications in EEAM, UNCP, with the aim: to determine the effect of population density on yield potential and compensation components of performance in rainfed late planting in the Mantaro Valley. Ran row planting. In response to plant population adjustment, using planting 270 seeds per row (90 kg / ha) was reached early flowering, necessitating 63.33 days to 50% flowering, achieving greater spike length with 8.667 cm. Whereas avoid lying, lower plant height was achieved using 450 seeds per row (150 kg / ha) to 101.9 cm. Performance components, the density 270 seeds per row (90 kg / ha) achieved greater facility with 514.3 spikes per m2, also obtained 23.53 grains per spike. Using 360 seeds per row (120 kg / ha) was achieved better grain filling with 71.47 grams per thousand grains (0.07147 grams per grain). Higher yield potential in the field, was obtained using 270 seeds per row (90 kg / ha) to 4338.33 kg/ha and yield components were obtained planting 360 seeds per row (120 kg / ha) 8083, 41 kg / ha.
