Micro Irrigation in Coriander (Coriandrum sativum L.) Under South Saurashtra Agro-climatic Conditions

Abstract

Abstract

A field experiment was conducted during 2008 to 2010 at Junagadh to evaluate methods (drip, mini sprinkler and flood irrigation) and levels of irrigation (0.4, 0.6 and 0.8 PEF) in coriander. The results revealed that mini sprinkler and drip irrigation significantly improved growth and yield attributes viz., plant height, branches/plant, umbels/plant and test weight and thereby increased seed and stalk yields along with higher net returns, B:C and water use efficiency (WUE) over flood irrigation. Similarly, irrigation at 0.8 pan evaporation fraction (PEF) enhanced growth and yield parameters viz. plant height, branches/plant, umbels/plant and test weight and ultimately increased seed and stalk yield with higher net returns and B:C ratio over irrigation at 0.6 and 0.4 PEF.
