Influence of cutting height and nitrogen fertilization on plant height and tiller production of guinea grass (Panicum maximum Jacq) pasture

A study was conducted to determine the effects of cutting frequency and fertilizer-N rates on growth and production of guinea grass (Panicum maximum Jacq). The experiment was conducted in Nsukka, Nigeria. Treatments comprised four levels of fertilizer N (0, 150, 300 and 450 kg N ha ') and four cutting intervals (3, 6, 9 and 12 weekly intervals). Plant height, tiller number and herbage dry matter yields were significantly increased by 6%, 44% and 53%, respectively, during the establishment year when fertilizer-Nrate was increased from 0 to 450 kg N ha'. The extent of weed cover was significantly (P < 0.05) reduced by 33% in 2000 when fertilizer-N rate was increased from 0 to 450 kg N ha'. Increase in interval between cuts from 3 to 12 weeks significantly (P < 0.05) increased plant height in all the years. Plant height was increased (P < 0.05) by 28% 34% and 28% in 2001, 2002 and 2004, respectively, when fertilizer N was increased from 0 to 450 kg ha'. Application of Nat 450 kg ha produced similar plant heights in 2001 with the 300 kg N ha' but differed from the 150 kg N ha'. Increase in nitrogen application progressively increased (P<0.05) plant height in 2002 and 2004. Key words: , , ,

ABSTRACT Rhizobacteria have a wide range of plant growth-promoting mechanisms of action, making them an alternative and/or complementary biological input for chemical fertilizers. In this respect, the present study aimed to assess growth and nitrogen accumulation in maize plants as a function of Azospirillum brasilense, Bacillus subtilis, zinc and nitrogen application at sowing. The experiment with the ‘AL Bandeirante’ maize variety was conducted in a greenhouse, using a completely randomized design. The treatments were arranged in a 2 x 2 x 2 x 2 factorial scheme, with six repetitions, considering the presence and absence of Azospirillum brasilense (5 g kg-1), Bacillus subtilis (5 mL kg-1) and zinc (20 g kg-1) in the seeds and addition or not of nitrogen (30 kg ha-1) to the soil. The variables assessed were plant height, stem diameter, leaf, stem, shoot, root and total dry weight, and shoot nitrogen content. Nitrogen fertilization in the absence of zinc increased shoot and total dry weight as well as shoot nitrogen content. Zinc applied to the seeds improved the total and stem dry weight of maize plants in the absence of Bacillus subtilis. Inoculation with Azospirillum brasilense and Bacillus subtilis increased the stem diameter and shoot nitrogen content of maize plants when nitrogen fertilization was not performed at sowing. There was no isolated or interaction effect between factors for plant height and root dry weight.
