ABSTRACT
Feeding escalating population is challenge of the time with ever declining resources. To address this, issue several approaches are under consideration. Nutrient application/addition is one of the best known and adopted strategies. A field experiment was conducted at Agriculture Research Institute (ARI) Mingora Swat, Khyber Pakhtunkhwa in summer 2016 aiming the effect of silicon fertilizer applied to acidic soil on yield of paddy as paddy is mostly affected through lodging in Swat valley. The treatments consisted of control, 50 kg silicon ha-1, 100 kg silicon ha-1 and 150 kg silicon ha-1. Field had 12 plots with size of 12 m× 6 m = 72m2. The experiment was conducted in randomized complete block design (RCBD) with 4 treatments having three (03) replications. Rice (Oryza Sativa L.) variety JP 5 was tested. The maximum plant height (90 cm) was recorded in T4 when silicon was applied at the rate of 150kg ha-1, followed by plant height (85cm) of T3, treated with 100kg silicon ha-1. The data on 1000 grain weight and straw yield of rice crop revealed that there were non-significant (P>0.05) pair wise differences among the means of the treatments. The significant maximum biological yield (9299 kg ha-1), grain yield (3901 kg ha-1) and Harvest index (42 %) was obtained in T3 when silicon was applied at the rate of 100 kg ha-1. From these results, it can be concluded that the application of silicon @ 100 kg ha-1 was found the best for improving the rice growth, yield and yield components.
