Effect of organic products on growth and yield of rice (Oryza sativa)

Abstract

During green revolution the use of chemicals in the form of fertilizers and pesticides give rise to increase in pollution of soil, water and air. It also causes harmful impact on the health sector of non-target living organism. This increases the demand for organic products. Therefore, this study was conducted to evaluate the effect of organic products the field trial was carried out in 2019 kharif season at the experimental central research farm, Department of Entomology, Sam Higginbottom University of Agriculture Technology and Sciences, Allahabad. The Randomized Block Design (RBD) method with total three replicas was used for this study. The following soil treatments were used: Soil Organic Supplement @ 10 kg/ acre, Humikure @ 5 kg/ acre, SuperMykorrizA @ 100g/acre, Non EdibleDeoiled Seed Cake @ 5kg/ acre, combination and control. The plant height at 30, 45, 60 and 90 Days After Sowing (DAS); number of tillers at 30 and 45 DAS; panicle length and yield at harvesting were recorded for growth and yield studies. The result revealed that the maximum plant height was in Combination at 30 DAS (58.8 cm), 45 DAS (68.96 cm), 60 DAS (83.72 cm) and 90 DAS (89.0cm), respectively. In Combination the number of tillers (18.86) and panicle length (25.81 cm) were highest which was followed by SuperMykorrizA, Humikure, Soil Organic Supplement and Non EdibleDeoiled Seed Cake when compared to control. Moreover, the yield was maximum recorded in combination (54.61 q/ ha) followed by Humikure (53.94 q/ ha), SuperMykorrizA (52.09 q/ ha), Soil Organic Supplement (51.97 q/ ha), Non EdibleDeoiled Seed Cake (50.55 q/ha) when compared to control (49.54 q/ ha). Therefore, the selected organic products in combination were showing increased in growth and yield when compared to control.
