Effect of seed soaking in nitrogen, phosphorus and herbicides solution on yield and other characteristics of wheat.

摘要

In order to explore the possibility of enhancing wheat (cv. Ghazanavi-98) productivity with limited inputs, an experiment was conducted at the Agriculture Research Farm of NWFP Agricultural University Peshawar, Pakistan during winter 2002-03. Seeds were soaked in pure water; 0.1 and 0.5% urea solution; and 0.1 and 0.5% SSP solution, 0.01% and 0.005% Buctril-M [bromoxynil] and 0.01% and 0.05% Puma super solutions. The seeds soaked in different solutions along with un-soaked control making 10 treatments were studied in the experiment. The experiment was laid out in RCB design with four replications. Seed soaking in different solutions significantly affected emergence m-2 seedling weight, plant height, spike m-2, grains spike-1, thousand grain weight, biological yield and grain yield (kg ha-1). Maximum emergence (110 m-2) was noted in the control while highest seedling weight (6.5 g) was recorded in plots in which seeds soaked in pure water had been sown. Tallest plants (88.10 cm) and more spikes (163.0 m-2) were observed in plots of seed soaked in 0.01% Buctril-M solution. More grains spike-1 (65.15) was noted in plots of seed soaked in 0.005% Puma super solution. Plants originating from seed soaked in 0.5% urea solution produced heaviest thousand grains weight (40.87 g). Highest grain yield (2396 kg ha-1) and biological yields (16 780 kg ha-1) were obtained from those plants from seed soaked in 0.1% urea solution..
