Title : Improved Fertigation Doses of Nitrogen, Phosphorus, Potassium and Sulphur in Garlic (Allium sativum L.) to Enhance Postharvest Soil Nutrient Status

Abstract :

The field experiments were conducted during the two consecutive rabi seasons 2018-19 and 2019-20 at farmer’s field in Dhariyakhedi village of Mandsaur district of Madhya Pradesh to assess the post-harvest status of soil nitrogen, phosphorous and potassium as influenced by different irrigation and fertilizer levels in drip fertigated garlic. The experiment consists of three levels of irrigation water i.e., IW/CPE ratio 0.60 (I1), 0.80 (I2), 1.00 (I3) and three levels of recommended doses of fertilizer i.e., 60% (F1), 80% (F2), and 100% (F3) for garlic crop. The initial fertility status of soil at experimental site with regard to nitrogen, phosphorus (P2O5), potassium (K2O) and sulphur were recorded as 260 kg/ha, 21.5 kg/ha, 380 kg/ha and 19.2 kg/ha respectively. Most of the crop growth and quality parameters viz., plant height, polar diameter, equatorial diameter, fresh weight and dry weight of garlic bulb were significantly influenced by different irrigation and fertigation treatments. Among different irrigation and fertigation levels, the treatment I3F3 recorded highest FUE (64.47 kg/kg), marketable bulb yield (147.43 q/ha) and B:C ratio (5.63). The drip fertigation treatment with IW/CPE ratio 1.0 and fertigation at a rate of 100:50:50:50 kg/ha (N:P:K:S) resulted in higher post-harvest status of soil with regard to nitrogen (275.29 kg/ha), phosphorus (24.52 kg/ha), potassium (402.54 kg/ha) and sulphur (21.37 kg/ha) content.
