A field experiment was conducted at the experimental area of Indian Agricultural Research Institute, New Delhi, during kharif season of 2012- 2014 to evaluate the effect of different crop geometries and irrigation methods on the yield and irrigation water use efficiency of bottle gourd (Lagenaria Sicenaria L.). The experiment consisted of three crop geometries (G1 - row distance 3m and plant distance 0.5m, G2 - row distance 2m and plant distance 0.75m and G3 - row distance 1m and plant distance 1.5m) with two methods of irrigation (I1- ridge & furrow and I2 – check basin). Results revealed that, yield and irrigation water use efficiency were significantly affected by both the methods of irrigation and planting geometries. Ridge and furrow method of irrigation recorded significantly (P<0.05) higher yield (25 t ha-1) as compared to check basin (21 t ha-1) method of irrigation. Plant geometry G1 recorded significantly higher yield (27.15 t ha-1) as compared to G2 (21.45 t ha-1) and G3 (19.45 t ha-1). The yield attributes viz. fruit length and fruit girth was also found to be higher in the crop geometry G1. The ridge and furrow method of irrigation resulted higher irrigation water use efficiency as compared to the check basin method. The study concluded that ridge and furrow method of irrigation with planting geometry of G1 resulted highest mean yield (30.9 t ha-1) and irrigation water use efficiency (467 kg ha-1cm-1).
