The study was carried out during the year 2015-16 to investigate the impact of harvesting times and drying methods on yield attributes of promising wheat TJ-83. Eight parameters of economic importance were studied which included: moisture content (%), plant height (cm), grains spikes m-2, spikelets spike-1, spike length (cm), harvesting index (%), biological yield (kg ha-1) and grain yield (kg ha-1). The results showed that wheat crop harvested on 130 (DAS) resulted in maximum 11.87% moisture content, 83.33 cm plant height, 54.33 grains spikes m-2, 12.11 spikelets spike-1, 19.33 cm spike length, 48.18% harvest index, 9946.67 kg biological yield ha-1 and 4792.00 kg grain yield ha-1. In case of drying methods, bag store resulted in highest 11.78% moisture content, 81.25 cm plant height, 51.75 grains spikes m-2, 10.91 spikelets spike-1, 18.66 cm spike length, 47.39% harvest index, 9693.8 kg biological yield ha-1 and 4453.8 kg grain yield ha-1 followed by bag (open). Lease figure yield ha-1 and 4372.7 kg grain yield ha-1.

To investigate the impact of various harvesting timings and drying methods on yield attributes of wheat variety TJ-83 under agro-ecological conditions of Tandojam.
A three-replicated Randomized Complete Block Design (RCBD) with factorial arrangements was used. Three drying methods (Bag (Under sun), Bag (Open), Bag (Store)) and four harvesting times (110, 120, 130, and 140 Days After Sowing (DAS)) were tested. Eight yield parameters were measured. The experiment was conducted during 2015-2016 at Sindh Agriculture University Tandojam.

Harvesting over-mature wheat causes losses due to shattering of grains and also delays the sowing of subsequent crops. The study showed that harvesting on 130 DAS resulted in maximum plant height, grains spikes m-2, spikelets spike-1, spike length, harvest index, biological yield ha-1 and grain yield ha-1.
Harvesting at 130 DAS resulted in the highest values for most yield attributes. Bag (Store) drying method generally resulted in higher moisture content, grains spikes m-2, spikelets spike-1, spike length, harvest index, and grain yield. Delayed harvesting (140 DAS) showed a negative impact on yield and yield contributing parameters.
Harvesting wheat at 130 DAS is recommended for achieving maximum grain yield. Bag (store) is a suitable drying method for getting more grain yield in wheat crop as compared to other drying methods.
