Experiment code 16.2.3.68
Experiment Title Response of pigeonpea to irrigatioon schedule
Research Type State Trial
Experiment Background Pigeon pea is the one of the most important pulse crop grown in India after chickpea. In Gujarat it is cultivated on 0.27 m ha area with production 0.34 m tons and productivity 1244 kg/ha. The cultivation of pigeonpea is confined to kharif season only. Thus productivity greatly determined by the amount of rainfall received and its distribution throughout growing season of pigeonpea. Low soil moisture during early-reproductive, reproductive phase and pod filling stage due to early withdrawal of monsoon affected the productivity of pigeonpea. Irrigation is the only option to replenish soil moisture. But excess soil moisture during reproductive stage delay the flowering and crop maturity. It also influences the flower formation and retention. Thus application of limited irrigation at proper stage is important for higher productivity.
