ABSTRACT
Optimum sowing dates provide favorable temperature and light duration to obtain maximum yield. Seed rate plays vital role in obtaining higher production through ensuring optimum population. Triticale is normally sown using time and seed rate of wheat. Experiments should be carried out to find out the proper sowing time and seed rate of triticale. For this purpose this field experiment was conducted to evaluate the effect of sowing dates and seed rates on yield of triticale. The field experiment was conducted at Agronomy Research Farm. The University of Agriculture Peshawar, Pakistan during winter season 2021-2022. The following treatments were applied, sowing dates (Oct.10, Oct.20, Oct.30, Nov.10, Nov.20, Nov.30, Dec.10 and Dec.20) and seed rates (100, 120, 140 kg ha-1). The experiment was laid out in RCB design in split plot arrangement having three replications. Variations among sowing dates and seed rates were observed. Triticale sown on 10th November performed better with respect to emergence m-2, tillers m-2, plant height (cm), grains spike-1, thousand grains weight (g) biological yield (kg ha-1) and grain yield (kg ha-1) while days to anthesis, days to maturity, flag leaf area (cm2), spike length (cm), spike weight (g) and spikelet spike-1 was higher in early sowing on 10th October. It was also revealed that early and late sowing of triticale caused reduction in these attributes. Results revealed that seed rate 100 kg ha-1 showed maximum days to emergence, days to anthesis, days to maturity, spike length (cm), spikelet spike-1 while emergence m-2, flag leaf area (cm2), grains spike-1, biological yield (hg ha-1) and grain yield (kg ha-1) were higher at seed rate 120kg ha-1. Higher tillers m-2, plant height (cm), spike weight (g) and thousand grains weight (g) were shown by seed rate applied at the rate of 140 kg ha-1. It was concluded that triticale sown on Nov.10 performed better with respect to emergence m-2, tillers m-2, plant height (cm), grains spike-1, thousand grains weight (g) biological yield (kg ha-1) and grain yield (kg ha-1). On Oct.10 days to anthesis, days to maturity, flag leaf area (cm2), spike length (cm), spike weight (g) and spikelet spike-1 was higher. Seed rate at the rate of 100 kg ha-1 showed maximum days to emergence, days to anthesis, days to maturity, spike length (cm), spikelet spike-1. 120 kg ha-1 performed better on emergence m-2, flag leaf area (cm2), grains spike-1, biological yield (hg ha-1) and grain yield (kg ha-1). Seed rate @ 140 kg ha-1 produce more tillers m-2, plant height (cm), spike weight (g) and thousand grains weight (g). Based on results it is recommended that triticale should be sown on Oct.10 to Nov.20 for higher grain yield. Its sowing should not be delayed from Nov.20 in Peshawar valley. Seed rate of 100 kg ha-1 should be used for higher grain yield of triticale.
