Effect of foliar spray of cow breeds urine on growth and yield of wheat (Triticum aestivum L.)

The present investigation entitled “Effect of foliar spray of cow breeds urine on growth and yield of wheat (Triticum aestivum L.)” was conducted during Rabi 2024-25 at the Agronomy Research Farm, College of Agriculture, Pune. The experiment aimed to assess the comparative efficacy of foliar application of cow urine from different breeds on growth, yield, quality, and nutrient dynamics in wheat. The research findings showed that the maximum mean grain (42.50 q ha^-1) and straw (54.26 q ha^-1) yield of wheat were obtained by using spray of Tharaparkar cow breed urine at 20% concentration. These yields were at par with spray of Rathi cow breed urine at 20% concentration and significantly superior over other treatments. The total nutrient uptake by the wheat crop showed significant differences. The highest total uptake of nitrogen (104.39 kg ha⁻¹), phosphorus (32.18 kg ha⁻¹) and potassium (75.68 kg ha⁻¹) was recorded under the Tharparkar urine treatments and interestingly, the higher nutrient uptake of nitrogen (105.7 kg ha⁻¹), phosphorus (32.18 kg ha⁻¹) and potassium (73.94 kg ha⁻¹) was recorded under the 20% CUS treatment, followed closely by Rathi urine treatments. The lowest uptake (86.91, 26.55, and 63.73 kg ha⁻¹ of N, P, and K, respectively) was observed under crossbred urine with water spray.
