Abstract
The study was carried out during the year 2017-18 to effect of sowing methods on growth and yield of wheat (Triticum aestivum L.) under zero and other tillage methods variety Sunheri was under different sowing methods. Randomized complete block design (RCBD) was used with three treatments T1 = Drilling zero tillage, T2 = broadcasting after tillage and T3 = drilling after tillage. The experiment was replicated three times. The observations were recorded on plant height (cm), tillers m-2, spike length (cm), spiklets spike-1, grains spike-1, seed index (1000-grain wt., g), biological yield (kg ha-1) and grain yield (kg ha-1). The results of the study summarized that the wheat variety sown by drilling (after tillage) showed remarkably superior performance with 81.03 cm plant height, 452.67 tillers m-2, 14.46 cm spike length, 17.33 spikelets spike-1, 45.33 grains spike-1, 50.66 g seed index (1000-grain weight), 6866.7 kg ha-1 biological yield and 3595.0 kg ha-1 grain yield. Drilling after tillage was followed by sowing method broadcasting after tillage with 77.06 cm plant height, 313.33 tillers m-2, 9.26 cm spike length, 14.66 spikelets spike-1, 36.00 grains spike-1, 40.00 g seed index (1000-grain weight), 6533.3 kg ha-1 biological yield and 3060.0 kg ha-1 grain yield. On the other hand drilling with zero tillage sowing method showed small 76.10 cm plant height less number of 320.67 tillers m-2, 8.00 cm spike length, 12.00 spikelets spike-1, 33.66 grains spike-1, 36.00 g seed index (1000-grain weight), 6500.0 kg ha-1 biological yield and 3071.7 kg ha-1 grain yield. It is concluded that the crop sown by drilling after tillage reduced more grain yield of 3595.50 kg ha-1 as compared to drilled with zero tillage 3071.7 kg ha-1 and broadcasted after tillage (3060.0 kg ha-1).
