Abstract
An experiment to investigate the influence of different NP-fertilizers and compost on maize plant growth was carried out in a pot experiment during 2009 at the Faculty of Agriculture, Gomal University, Dera Ismail Khan, Pakistan. The experiment was laid out in a complete randomized design. According to analysis of variance, the four different sole fertilizers (Urea and DAP (Di-ammonium phosphate) @ 50 and 100ppm), two fertilizer formulations (DAP + Compost @ 50 and 100ppm) and control manifested highly significant (p£0.01) differences for mean values of maize growth parameters. Overall, the fresh root weight was 7.50 g (Urea @ 50ppm) to 15.36 g [DAP + Compost @ 100ppm], fresh shoot weight was 22.53 g (Urea @ 100ppm) to 33.93 g (DAP + Compost @ 50ppm), root length was 39.33 (DAP @ 50ppm) to 56.33 cm (Urea @ 50ppm), shoot length was 70.50 cm (DAP + Compost @ 100ppm) to 81.50 cm (DAP @ 100ppm), dry root weight was 0.67 g (Urea @ 50ppm) to 1.27 g (DAP + Compost @ 100ppm) and dry shoot weight was 2.83 g (Urea @ 50ppm) to 4.00 g (DAP + Compost @ 50ppm) among the said seven treatments. The fertilizer formulations DAP + Compost @ 50ppm and DAP + Compost @ 100ppm performed better in boosting the maize growth parameters about root and shoot. It was concluded that said fertilizer formulations can provide significant positive enhancement to maize growth as compared to sole fertilizers.
