GAJENJE KUKURUZA PDF

0 Comment

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.

Cultivar interaction with environmental factors location, year, soil type, cultural operations used, etc. Calculations of production of wheat, corn and soybean on farms involved in education program inhave shown that corn has the highest gross margin 92, Institut za kukuruz ‘Zemun polje’, Zemun e-adresa: An objective evaluation of gajenjd hybrids in intensive cropping systems requires identification not only of yield components kukuruzs other agronomically important traits but also of stability parameters.

The experiments were kukuuza out in a randomised block design with four replications. The soil in Mojsinje is a heavy-textured vertisol acid in reaction pHH2O 5. Biosci43, str.

Individual values were not significantly different from the average value in any hybrid. Due to their more gajenjs stability parameter values, medium-early hybrids can be recommended for low-intensity cultural practices and stressful environments.

Sowing was conducted in the first half of April in both years at all locations. Agronomy Journal, 85, The regression coefficient in the second year was lowest in HY06, highest in HY04, and closest to the average value in HY The results obtained were subjected to the factorial analysis of variance using F and LSD tests, and stability parameters were evaluated by regression analysis Eberhart and Russell, 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.

The significantly different value of bi in HY02 in the first year suggests greater-than-average stability of this hybrid as compared to the other hybrids tested. Help Center Gzjenje new research papers in: Agricul7, str.

Moreover, the high value of GEI is often associated with a low correlation between genotypic and phenotypic values, thereby reducing the selection progress. Maydica37, str.

The hybrids with higher mean values of the traits, regardless of maturity group, generally exhibited sensitivity i. Enter the email address you signed up with and we’ll email you a reset link. A broader picture of grain yield cannot be completely predicted by this model. The highest regression coefficient was determined in HY06 and the lowest in HY Journal of Central European Agriculture, 6 3 Weed Sci37, str.

Results of investigation shows a possibilities to increase yield and total maize production. Remote access to EBSCO’s databases is permitted to patrons of subscribing institutions accessing from remote locations for personal, non-commercial use.

Monitoring showed that crop rotation gives good results. The hybrids belong to different maturity groups, viz. However, remote access to EBSCO’s databases from non-subscribing institutions is not allowed if the purpose of the use is for commercial gain through cost reduction or avoidance for a non-subscribing institution.

Materials and methods Eleven double-way maize hybrids developed at the Zemun Polje Maize Research Institute were assessed. Results and discussion The analysis of variance revealed significant differences in grain yield, grain moisture content at harvest, 1,kernel weight and ear length between hybrids belonging to different maturity groups and between locations Table 1.

Genotypes with high mean yields and specific adaptability to unfavourable environments are very rare Scapin et al. The test hybrids and locations showed significant differences in grain yield, grain moisture content at maturity, 1,kernel weight and ear length. Much greater heterogeneity in bi was observed in the first year, which was more favourable, resulting in more pronounced differences among genotypes in their response to environmental conditions.

Using this criterion, Flores et al.
