Abstract:
The present research work in entitled “Response of summer groundnut (Arachis hypogaea L.) to irrigation level and anti-transpirant on quality, soil parameters and economics” was carried out during summer season 2019-20 at Instructional Farm, Department of Agronomy, College of Agriculture, Junagadh Agricultural University, Junagadh. The soil of experimental unit was medium black in texture with pH 7.9 and EC 0.33 dS/m. The soil was low in available nitrogen (285 kg/ha), high in available phosphorus (27 kg/ha) and medium in available potash (232 kg/ha). The experiment encompassed of nine combinations, three levels of irrigation schedule and three levels of anti-transpirant embedded in a split plot design with four replications. The details of treatments are as follows, I₁AT₁ [0.6 IW/CPE + Control (water spray)], I₁AT₂ (0.6 IW/CPE + Kaolin 6% spray at 45 and 75 DAS), I₁AT₃ (0.6 IW/CPE + PMA 0.032% spray at 45 and 75 DAS), I₂AT₁ [0.8 IW/CPE + Control (water spray)], I₂AT₂ (0.8 IW/CPE + Kaolin 6% spray at 45 and 75 DAS), I₂AT₃ (0.8 IW/CPE + PMA 0.032% spray at 45 and 75 DAS), I₃AT₁ [1.0 IW/CPE + Control (water spray)], I₃AT₂ (1.0 IW/CPE + Kaolin 6% spray at 45 and 75 DAS) and I₃AT₃ (1.0 IW/CPE + PMA 0.032% spray at 45 and 75 DAS). The quality, soil parameter and economics were significantly affected by different irrigation scheduling and anti-transpirant treatments and recorded significantly higher with 1.0 IW/CPE irrigation scheduling and kaolin anti-transpirant treatments.
