摘要

Purpose

Tuberose is a versatile ornamental plant with significant aesthetic social and commercial values. The optimal flower production is negatively impacted by soil water stress. In water-limited areas, deficit irrigation management and soil water conservation can boost both yield and water productivity.

Methods

A three-year field trial was conducted to evaluate four irrigation regimes, including drip-based irrigation at 0.6 (I1), 0.8 (I2), 1.0 (I3) of pan evaporation (Ep), and surface irrigation (I4). Additionally three mulch treatments were tested: no-mulch (M0), paddy straw mulch (M1), and black polythene mulch (M2). The experiment was set up in a split-plot design with three replications.

Results

The results showed that the I3M2 combination demonstrated the highest growth, flowering characteristics, spike yield, flower yield (9.06 t ha−1), vase life, moderate water productivity, and the greatest availability and uptake of macronutrients, which were on parity with the I2M2 combination. Under severe water stress, the I1M2 combination provided an alternative for achieving a slightly higher yield and the highest water productivity. The varied drip irrigation levels could save 19.0–31.7% of water compared to farmers’ surface irrigation. The water-yield functional models predicted the maximum flower yields of 8.48–9.30 t ha−1 at 260–320 mm of irrigation water and 580–620 mm of seasonal water consumption.

Conclusion

Drip irrigation at 0.8 of pan evaporation, combined with black polythene mulch, proved to be the best and is recommended for tuberose growers in the Indo-Gangetic plains of eastern India.
