Abstract:

A field experiment was conducted at Central Arid Zone Research Institute, Regional Research Station, Pali-Marwar during winter season (rabi) of 1997-98 to 2001-02 to find out the effect of bunding, tillage and straw mulch on taramira yield and water productivity. Field bunding significantly increased mean taramira biological yield by 13.4% and seed yield by 18.1% over no bunding due to increased availability of soil moisture. Water use efficiency also increased by 0.6 kg ha-1 mm-1 over no bunding. The effect of deep tillage was variable and largely governed by the amount and distribution of rainfall. Deep tillage during intermittent drought period effectively conserved the soil moisture and significantly increased the seed yield of taramira. Straw mulching @ 5 t ha-1 significantly increased mean seed yield of taramira by 25% over no mulch, with increased water use efficiency by 1.8 kg ha-1 mm-1. It is recommended that field bunding, deep ploughing during monsoon and straw mulching @ 5 t ha-1 may be followed for enhancement of taramira seed yield and water productivity through in-situ moisture conservation.
