Yield of wheat varieties under solid and skip row geometries

摘要

The objectives of the study was to find out the performance of different wheat varieties sown under solid and skip row geometries. An experiment was carried out at New Development Form of KPK Agricultural University Peshawar, Pakistan during winter season of 2002-2003. The experimental setup was randomized complete block design (RCBD) with split plot arrangement having three replications. Sowing was done on 18^th November, 2002. Row geometry was allotted to main plot and different wheat varieties were allotted to sub plots. The size of each sub plot was 2.4m by 5m. Six different wheat varieties (Bakhtawar-92, Fakhar-e-Sarhad, Ghaznavi-98, Nowshera-96, Chakwal, and Khyber-87) were planted in skip and solid row geometries randomly. In solid row geometry the row to row distance was 30 cm and in skip row geometry, pairs of row were 60 cm apart and within pairs the row to row distance was 30cm. The following parameters via emergence m^-2, days to anthesis, plant height, number of tillers m^-2, spike density m^-2 were studied in the experiment. The solid row geometry reported better emergence, took more days to anthesis and gave higher spike density as compared to skip row geometry. Skip row geometry produced taller plants than solid row geometry. Performance of the two wheat varieties, Fakhar-e-Sarhad and Ghaznavi-98 was found appreciable than the other four varieties i.e., Bakhtawar-92, Nowshera-96, Chakwal, and Khyber-87.
