Quality of Gum Guar [(Cyamopsis tetragonoloba (L.) Taub.) as Influenced by Irrigation and NP Fertilization Under North Saurashtra Region

A field experiment was conducted during the summer season of 2013 and 2014 on gum guar to evaluate the effect of irrigation scheduling (0.4, 0.6, 0.8 and 1.0 IW: CPE ratios) and NP fertilization (00–00 kg N-P₂O₅ ha⁻¹, 10–20 kg N-P₂O₅ ha⁻¹, 20–30 kg N-P₂O₅ ha¹and 30–60 kg N-P₂O₅ ha⁻¹) at Krishi Vigyan Kendra, Junagadh Agricultural University, Nana-Kandhasar (Chotila), Gujarat under north saurashtra region. The experiment was laid out in a split plot design and replicated thrice. The whole quantity of NP fertilizer was applied as basal through of urea and di-ammonium phosphate in all the plots as per the treatments. Significantly higher protein content (24.32%), protein yield (325.44 kg ha⁻¹), gum content (29.27%) and gum yield (390.94 kg ha⁻¹) were recorded under 0.8 IW: CPE ratio over IW: CPE ratios of 0.4 and 0.6, however it remained at par with1.0 IW: CPE ratio. Application of 20–40 kg N-P₂O₅ ha⁻¹ significantly increased in protein content (24.27%), protein yield (321.64 kg ha⁻¹), gum content (28.84%) and gum yield (382.75 kg ha⁻¹) over control.
