Abstract

Effect of different fertilizer treatments on the performance of some local rice varieties under SRI (system of rice intensification) and conventional management practices at district Swat

Highlights

Managing the rice crop according to a set ofRice (Oryza sativa L.) is the third biggest principles known as the System of Rice crop in the world after wheat (TriticumIntensification is one of the recent aestivum L.) and cotton
The present proposed study aims (1) to compare the nutrient-use efficiency of the SRI system and the conventional cultivation method, (2) to estimate the nutrient requirements per unit of rice grain produced under SRI and conventional methods for producing a given grain yield, and we want to be sure that the system being promoted has a sound scientific basis, on one hand, and is kept as simplified as possible to facilitate more widespread adoption among farmers
Rice systems i.e., 1) SRI and 2) conventional management practices and rice varieties, i.e., 1) Fakhre Malakand, 2) Dilrosh-97, and 3) JP5 in all possible combinations were assigned to main plots whereas the fertilizer treatments were assigned to sub-plots

Summary

Managing the rice crop according to a set of

Rice (Oryza sativa L.) is the third biggest principles known as the System of Rice crop in the world after wheat A compilation of results from 11 surveys in 8 countries, including 16,000 SRI farmers, has shown, on average, a 47% yield increase, 40% water savings, 23% lower production costs, and 68% increase in farmer income, compared to conventional rice cultivation [11, 12]. Statistical perusal of the data showed that SRI, cultivation methods, varieties and fertilizers treatments significantly affected number of tillers m-2 of rice while the effect of years was no significant. The application of NPK at the rate of 100-6040-20 NPK in combination with Zn resulted in highest number of tillers followed by 100-60-40-0 NPK and Zinc kg ha-1 (24.76) while lower number of tillers were counted in control plots where no amendment was practiced
