Assessment of combined effect of human feces compost and single superphosphate on the behaviour of wheat production

Abstract

Application of organic fertilizers in improving soil fertility has become a major factor that has enabled the world to feed billions of people. However, the required quantities of organic material are enormous, so it becomes necessary to combine different types of fertilizers to feed plants. The effectiveness of human feces compost (HC) alone, as well as in combination with single super phosphate (SSP), was evaluated in the present study. A field experiment was conducted at farmer field located in district Swabi (Pakistan). A total of eight possible treatments combination were arranged in randomized complete block design (RCBD), replicated four times. Two levels of human feces compost (HC), including control (HC0: control and HC1: 7.5 t ha-1) and four levels of P, as single superphosphate (SSP), including control (P0: control, P1:40 kg ha-1, P2: 60 kg ha-1 and P3: 90 kg ha-1) were utilized in the experiment. Results revealed that among all the treatments, combined application of SSP at 60 kg ha-1 along with 7.5t ha-1 HC significantly improved the growth, as well as the yield parameters of wheat crop. These results allow saving a half of usually made mineral fertilizer dose for the cultivation of wheat crop. Combined use of HC and SSP were strongly recommended for obtaining maximum wheat yield in the prevailing soil and environmental conditions.
