- Abstract
A field experiment was carried out to study the efficacy of hydrogels under sensorbased irrigation on growth and productivity of tree mulberry during 2022-23. The experiment was laid out in Randomized Complete Block Design (RCBD) with nine treatment combinations and three replications, observations were recorded at 30th, 45th and 60th Days After Pruning (DAP). Pooled data of five crops were analysed. The hydrogels were applied during beginning of first crop. Main plot include two different types of hydrogels viz., Pusa hydrogel (T11- Pusa hydrogel @ 1 kg/ac, T2- Pusa hydrogel @ 2 kg/ac, T3- Pusa hydrogel @ 3 kg/ac and T4- Pusa hydrogel @ 4 kg/ac) and Zeba hydrogel (T5- Zeba hydrogel @ 3 kg/ac, T6- Zeba hydrogel @ 4 kg/ac, T7- Zeba hydrogel @ 5 kg/ac, and T8- Zeba hydrogel @ 6 kg/ac) and T9-control without hydrogel. Among hydrogels, Zeba hydrogel @ 6 kg/ac (T8) showed highest plant height (201.40, 243.17 and 270.74 cm, respectively), shoot length (131.89, 188.68 and 221.99 cm, respectively), number of shoots per plant (21.34, 23.41 and 28.83 no., respectively), number of leaves per shoot (23.07, 30.10 and 42.33 no., respectively), leaf area (92.72, 165.89 and 190.01 cm², respectively) and leaf yield (3.25 kg per plant, 6688.66 kg per ha and 33.44 tons per ha per year). Water productivity was found highest in mulberry plots laid out with Zeba hydrogel @ 6 kg/ac (T8) found to be 590.29 kg per ha cm along with water used to produce per kg of leaf was recorded to be 169.40 L. Compared to without hydrogel plot 33.23 per cent of water can be effectively saved using Zeba hydrogel @ 6 kg/ac (T8).
