Leaf Clipping and Population Density Effects on Green Fodder and Grain Yield for Hybrid Maize (Zea mays) in Bangladesh

Allozyme Frequency Changes Associated with Selection for Increased Grain Yield in Maize (ZEA MAYS L.).

Frequency changes of alleles at eight enzyme loci were monitored in four long-term maize selection experiments. The results indicate that changes in frequencies of the alleles at these loci are associated with changes due to selection for improved grain yield. The frequencies changed more than is consistent with the hypothesis of selective neutrality. In addition, significant deviations from a ...

Estimation of heterosis for grain yield components in Maize (Zea mays L.)

Heterosis plays an important role in achieving improvement in crop production. About 69 F 1 hybrids obtained by crossing twenty three lines and three testers in a line × tester fashion were used to derive the information on degree of heterosis over mid, better and standard parent in maize. Sixty nine crosses and their parents including one check CoH(M)5 were evaluated in a Randomized Block Desi...

EFFECT OF THE APPLICATION OF DRIED SLURRY ON YIELD AND CHEMICAL COMPOSITION OF MAIZE FODDER (Zea mays)

The experiment was carried out to evaluate the effect of different levels of dried slurry (DS) as source of nitrogen fertilizer on yield and chemical composition of maize fodder (Zea mays). Four levels of DS (0, 10, 12 and 14 ton/ha) were applied in a Randomized Block Design (RBD). Green biomass yields was significantly higher in DS incorporated groups compared to control. The highest (P<0.01) ...

Non-destructive leaf area measurement in maize (Zea mays L.).

In this research, leaf area prediction model was developed for some leaf-used maize (Zea mays L.) cultivars namely Coluna, Luce, Maveric, Ranchero, TTM-813, Zamora and RX-788 grown in Black Sea region of Turkey. Lamina width, length and leaf area were measured without destroying the leaf to develop the models. The actual leaf areas of the plants were measured by PLACOM Digital Planimeter and mu...
