Abstract:
An experiment was conducted for 2 years (Dec.2020 to March-2021 and Nov. 2021 to Feb. 2022) to assess sweet corn crop performance under various irrigation water management strategies. Sweet corn was grown in winter season at the research farm. JAU, Junagadh, Gujarat, India. Total 32 treatments comprising of aerated and non-aerated irrigation, deficit irrigation (0.7 ETc) and full irrigation (1.0 ETc), deficit fertigation (0.7 RDF) and full fertigation (1.0 RDF), Surface drip and subsurface drip and with/ without mulch. The yield of fresh green cob and fodder were observed from each of 2 replications of each of 32 treatment. The fresh cob yield was increased by 8.94% due to aerated irrigation as compared to non-aerated. The increase in irrigation applications from 70% of ET_c to 100% ET_c increased the fresh cob yield by 15.07%. The yield could be enhanced by the tune of 17.77% by increasing the fertigation level from 0.7 RDF to 1.0 RDF. The mulch adoption helped increase yield by 21.67% under surface drip irrigation while by 7.57% only under subsurface drip irrigation as compared to no mulch. The adoptions of subsurface drip irrigation could increase the cob yield by 22.69% under no mulch and 8.47% under mulch as compared to surface drip irrigation.
