Response of Maize Cultivars to Different NP-levels under Irrigated Condition in Peshawar Valley

Ashiq Saleem, Habib Iqbal Javed, Zulfiqar Ali and Ihsan Ullah
The present study included evaluating different morphological and seed parameters of maize germplasm and their response to NP-levels for higher production. Germplasm having different morphological characteristics affect their performance with their different genetic constitution. In order to increase maize yield unit area-1, selection of a suitable germplasm in maize is of greatest importance. Different NP-levels used were Control, 100:50, 120:60, 140:70 and 160:80. While the germplasm studied were FRHY-10, EV-1089, Margalla, Rawal and Gauher. Results showed that grain yield of the germplasm was significantly affected by NP-levels and highest grain yield was produced at 140:70 followed by 120:60, 160: 80, 100:50 and control. Significant differences were also obtained with NP levels in the germplasm with regard to the plant height, number of leaves/plant. Days to 50% Silking, were also significantly affected by both NP-levels and germplasm. Highest grain yield of 3550 kg ha-1 was recorded in genotype FRHY-10 with NP level of 140:70 NP kg ha-1.
