Description |
In order to find the ways and means of utilizing human urine and cattle urine as liquid fertilizer for crop production and to assess the effect on soil properties, growth and yield of vegetable crops, experiments were carried out under laboratory, field and green house conditions from 2009 to 2011. The urine from persons of different age group and diet and different categories of cattle was characterized and changes in chemical composition when incubated under open and closed conditions was mentioned. Field experiment was conducted in farmer’s field with ashgourd, french bean, pole bean and pumpkin as test crops and 14 treatment combinations at Nagasandra village, Doddaballapur, Bangalore rural district to study the effect of repeated application of human urine and cattle urine on soil properties, growth and yield of vegetable crops. In a green house experiment effect of higher doses of human urine and cattle urine on growth and yield of tomato in red, laterite and black soils was studied. The fresh urine from persons of vegetarian and non-vegetarian diet and of different age groups and of different categories of cattle were acidic in reaction, had appreciable amount of soluble salts, primary and secondary and micronutrients. Urine from non-vegetarians had more nutritive value when compared to vegetarians. Upon incubation, nitrogen concentration decreased but there was no much variation in phosphorus and potassium concentration. The pH of urine samples of all category turned to alkaline reaction with time. In the field experiment, application of recommended dose of nitrogen through human urine in three split doses plus gypsum recorded higher yield (39.2, 14.2, 17.4 and 38.7 t ha-1, for ashgourd, french bean, pole bean and pumpkin grown sequentially), growth and yield parameters, nutrients uptake, soil available nutrients, soil microbial population and B:C ratio as compared to other treatments. In the green house experiment, application of 2 times the recommended dose of N through human urine to red and laterite soils recorded higher tomato fruit yield (3.6 and 3.4 kg plant-1, respectively), growth and yield parameters, quality components, nutrients uptake, soil available nutrients and soil microbial population as compared to other treatments. In black soil, all these components were found significantly higher in treatment receiving 2 times the recommended dose of N through chemical fertilizers as compared to other treatments. |
