The rational application of nitrogen fertilizer and close planting are two important ways to obtain high yields efficient growth from maize (Zea mays L.). This study utilized the varieties DengHai 618 XianYu 335 as test materials 2019 2020 variety material in 2021. densities were 7.5 × 104 plants ha?1 12.0 ha?1, respectively. Application rates within range 0–765 kg per 45 considered gradient. r...

A field experiment was conducted during the autumn season (2019) at Research Station of Field Crops Department / College Agriculture, Tikrit University, to study effect spraying potassium on growth characteristics, yield and its components three genotypes corn (Zea Mays L.). The first factor contained two concentrations foliar with (2500 5000 ppm) second (DKC6589, DKC6120, ZP). carried out in a...

The screening of forty eight maize in breds from International Maize and Wheat Improvement Center was carried out to estimate the genetic diversity results indicated presence considerable diversity. experiment conducted a randomized complete block design with three replication phenotypic data were analyzed using twenty one agro-morphological traits. grouped into eleven clusters based on Mahalan...

Combining ability of inbred lines is the ultimate factor determining future usefulness for hybrid development while, an idea about nature gene action controlling yield and contributing characters important fruitful breeding programme. Owing to this, present study was carried out investigate General Ability (GCA) Specific (SCA) effect parental hybrids respectively, deduce type regulating grain i...

This research was conducted to determine the relationship between seed developmental characteristics and yield components in a population of maize (Zea mays L.) grown at different potassium fertilizer rates. The information could be utilized as alternative selection criteria for genotypes with high-yielding potential. Experimental field Horticulture Seed Agency, Pekanbaru. Seven four rates were...

seven maize inbred lines were crossed in a complete diallel cross design at the seed and plant improvement institute, karaj, iran, during the 2006 growing season. the parents and 42 f1 hybrids were grown in the research field of islamic azad university of firoozabad, firoozabad, iran, using a randomized complete block design (rcbd) with three replications, during the 2007 growing season. the ha...

Relay cropping is a method that increases total productivity through maximum utilization of resources. In this study, we planned field experiment, which was conducted at the Regional Agricultural Research Station, Ishwardi, Pabna during 2016-2017 and 2017-2018 to find out most suitable way relaying mukhikachu (MU) with hybrid maize get benefit. Seven treatments: T1= silking stage (100 DAS), T2 ...
