Abstract

In order to examine its morpho-phenological and yield response of wheat to tillage practices and straw incorporation, the study was carried out in saline sodic soils, using tillage practices, wheat straw amendments and gypsum amendments as treatment factors in a randomized complete block design (RCBD) with four replications. Tillage practices comprised of shallow tillage (ST) to 0.10 m with two passes of a disk harrow and deep tillage (DT) using moldboard ploughing to a depth of 0.25 m followed by two passes of disk harrow as under ST. Wheat straw amendments consisted of 3 mg ha-1 (WS3), 7 mg ha-1 (WS7) and 10 mg ha-1 (WS10); while gypsum amendments consisted of 25% of gypsum requirement (GR25), 50% of gypsum requirement (GR50) and 75% of gypsum requirement (GR75). These treatment factors were tested under conventional practice (CK) with no straw, only NPK and gypsum; and control (CTRL) without straw and gypsum amendments. It was concluded that seed emergence, number of tillers, plant height, spike length, grains spike-1 , number of grains spike-1 , seed index and grain yield in wheat increased significantly (PSTWS10 >DTWS7 >STWS7 >DTWS3 >STWS3); while the order for seed emergence, number of tillers, grains spike-1 , seed index and grain yield stood as STWS10 >DTWS10 >STWS7 >DTWS7 >STWS3 >DTWS3.
