INVESTIGATING THE IMPACT OF DIFFERENT SOWING METHODS ON WHEAT (TRITICUM AESTIVUM L.) GROWTH AND YIELD IN LARKANA

In the investigation conducted throughout 2023, the impact of various planting techniques on TD-1 wheat (Triticum aestivum L.) variety growth and yield was examined. The study encompassed three distinct sowing methods: T1 = drilling, T2 = broadcasting and T3 = ridges. Various parameters were observed, such as the plant's height (cm), the number of tillers per square meter (m-2), spike length (cm), number of grains in step with the spike (g), the weight of 1000 grains or the seed index (g), and yield of grains (kg ha-1). The summarized statements of the research are presented below. The wheat variety sown using the drilling method exhibited notably superior performance, showcasing a plant height of 63.30 cm, 452.67 m-2 tillers, a 10.13 cm spike length, 15.00 spikelets in accordance with spikes, 35.33 grains for each spike, a 43.66 g seed index (1000-grain weight), a 6218 kg ha-1 biological yield, and a 4325 kg ha-1 grain yield. The ridge-sown crop displayed characteristics such as a 63.20 cm plant height, 313.33 m-2 tillers, a 8.23 cm spike length, 13.33 spikelets contained in each spike, 33.66 grains through to each spike, a 34.66 g seed index (1000-grain weight), a 5614 kg ha-1 biological yield, and a 3922 kg ha-1 grain yield. In contrast, the broadcasting method yielded a plant height of 65.87 cm, 320.67 m-2 tillers, a 9.03 cm spike length, 13.33 spikelets on account of spikes, 36.00 grains for spikes, a 41.33 g seed index (1000-grain weight), a 6371 kg ha-1 biological yield, and a 4141 kg ha-1 grain yield. In conclusion, the drilling method proved to be the most favorable, resulting in a greater yield of grains of 4325 kg ha-1 compared to broadcasting (4141 kg ha-1) and ridge sowing (3922 kg ha-1).
