| dc.description.abstract | Treated sugar mill effluent was used in field experiment to investigate its effect on paddy-cowpea cropping sequence. The experiment was conducted at Research and Development Farm, M/s. Sri Chamundeshwari Sugars Ltd. Mandya District, during 2012-14. The first experiment was laid out in randomized complete block design with eight treatments replicated thrice. It included paddy as test crop during Kharif to know direct effect of treated sugar mill effluent irrigation and cowpea during summer to study its residual effect. Continuous treated sugar mill effluent irrigation along with RDF recorded significantly higher grain yield of paddy (53.8 q ha-1), nutrient uptake, soil available nutrients and B:C ratio (2.24) as compared to RDF with fresh water irrigation. Subsequently, residual effect of the same treatment recorded higher seed yield (996 kg ha-1), nutrients uptake, soil available nutrients and B:C ratio (1.93) of cowpea as compared to all the other treatments in paddy-cowpea sequence. Based on the results of the first experiment on paddy the second experiment on treated effluent irrigation in combination with amendments in paddy was laid out in splitplot design during summer. Continuous treated sugar mill effluent irrigation and RDF recorded higher grain yield (52.2 q ha-1) followed by fresh water irrigation along with RDF (46.7 q ha-1). Among amendments, combined application of gypsum and green leaf manure and green leaf manure alone recorded significantly higher grain yield (46.4 and 45.4 q ha-1, respectively) over other treatments. However, they were on par with each other. Interaction effect of treated sugar mill effluent irrigation along with RDF and combined application of gypsum + green leaf manure recorded significantly higher grain yield (53.7 q ha-1). Economic analysis revealed that interaction effect of continuous treated sugar mill effluent irrigation along with RDF and green leaf manure as amendment recorded higher B: C ratio (2.12). | en_US |
