    Abstract

    This book focuses on best management practices for drip irrigated crops. It cover irrigation methods, scheduling of micro irrigation, and mulching and crop performance. Micro irrigation techniques with diverse crops are discussed, including sweet pepper, chili, tomatoes, cauliflower, wheat, sweet peas, sugarcane, and potatoes. The performance of the various techniques has been tested and evaluated in the field. Written by experts on micro irrigation, this valuable book is a must-have for micro irrigation professionals as well as advanced students.

    Abstract Effects of extended photoperiods in red and blue LED supplemental lighting (SL) at constant photosynthetic photon flux density (PPFD) on growth, yield and quality of ‘Patagonia’ iceberg lettuce (Lactuca sativa var. capitata ‘Iceberg’) were evaluated. Different treatments were 14 hours of SL (T₁), 16 hours of SL (T₂) and 18 hours of SL (T₃) under the similar ratio of 70:30 (R:B) at supplemented PPFD of 70 μmolm⁻²s⁻¹ in comparison to treatment T₄ i.e., No Supplemental Lighting (NSL) or control. The experiment was laid in a completely randomized design, and lettuce plants grown in soilless media in 100% complete nutrient solution under naturally ventilated greenhouse in winter season were planted in six replicates per treatment. Supplemental lighting was only used when the outside solar radiation dropped below 300 W/m². The average temperature and relative humidity were within the range of 11.8–25 °C and 66.3–88.3%, respectively. The results indicate that growth parameters enhanced in respect of increased photoperiods. Yield was significantly different in all the treatments with highest value of 12.8 Kg/m² under treatment T₃ followed by 12.0 Kg/m², 11.1 Kg/m² and 10.3 Kg/m² under T₂, T₁ and T₄, respectively. Plants raised under SL treatments matured earlier in comparison to control. Treatment T₃ significantly raised quality of lettuce in terms of L-ascorbic acid content, firmness, total phenolic content, DPPH radical scavenging activity and total soluble solids. Our findings demonstrate that extended photoperiods in supplemental LED lighting systems could improve growth, increase yield and enhance quality of iceberg lettuce grown in soilless media under protected cultivation.
