The book explores the effects of various drip irrigation configurations and regimes on cumin productivity over two growing seasons . The study employs a split-split plot design, analyzing eighteen treatment combinations of irrigation levels (0.6, 0.8, and 1.0 IW/ETc), lateral spacings (60 cm, 70 cm, and 80 cm), and emitter geometries (hexagonal and triangular).Findings reveal that an irrigation regime of 0.8 IW/ETc maximizes seed yield (1255.78 kg/ha) while minimizing water wastage. The optimal lateral spacing is 60 cm, and triangular emitters provide better water distribution and yield...
