GAJENJE KUKURUZA PDF

Za intenzivno gajenje hibrida kukuruza neophodno je, pored komponenti prinosa i drugih agronomski važnih osobina biljke, za objektivnu ocenu njihovih. Ministri Evropske unije odobrili su gajenje kontroverznog genetski modifikovanog novog roda kukuruza, TC američke kompanije DuPont Pioneer. S druge strane, domaće životinje troše tokom uzgoja velike količine semena kukuruza, što sa obzirom na ograničen zemljišni fond obično znači učestalo gajenje.

The efficacy of selection for grain yield potential could be increased by indirect selection via characters highly correlated with grain yield such as stay green. Under dynamic stability, a genotype or cultivar attains a constant high yield response to changes in the environment.

Sample of S1 progenies studied in more than one environment is sufficient for reliable estimate of mean value and variability of grain yield and grain moisture in gajenne populations of maize. Becker and Leon established a biological or static concept of stability under which a stable genotype displays a minimal variance for yield, for instance across different environments. Genetika, 42 1 No warranty is given about the accuracy of the copy.

HY01 and all hybrids from FAO group gave lower average yields, and were more stable than the other hybrids. The highest and significant deviation from regression was exhibited by Gqjenje 1. The experiments were laid out in a randomised block design with four replications.

The regression coefficient in the second year was lowest in HY06, highest in HY04, agjenje closest to the average value in HY This abstract may be abridged. The role of integrated weed management IMW in agro ecosystem health.

Significant GEI results from changes in the relative ranking of genotype performance across environments, and it affects breeding progress Pham and Kang, Zbornik radova Instituta za ratarstvo i povrtarstvo, Novi Sad, 33, Cultivars are classified according to the value of their linear regression coefficients into those having bi less than, equal to, or greater than unity, as gajenme as according to the value of the variance of regression deviations equal to or different from zero.

Journal of Central European Agriculture,15 4p.

Most medium-early hybrids give low yields, along with generally favourable values of stability parameters i. The lowest average yield was produced by HY01, and the highest by HY The stability parameters indicate that this hybrid exhibits a specific response to the particular agroenvironmental conditions i.

Given the relatively narrow geographic area, the locations selected for the study are representative of the major types of soils used for maize production in this region. Monitoring showed that crop rotation gives good results. Among medium-season hybrids, HY06 gave higher yields and had less favourable values of stability parameters compared to medium-late hybrids.

This was also confirmed by significant deviations from regression, suggesting that more favourable conditions induced strong hybrid x environment interactions.

A correct and on time application of grooving technology, such as sowing data, plant density, crop rotation, fertilization, can reduce negative effect of unfavorable climate conditions on maize. Parametri stabilnosti prinosa zrna i komponenti prinosa hibrida kukuruza razlicitih FAO grupa zrenja.
