Pest Incidence as Influenced by Different Sowing Methods and Varieties of Rice

Abstract

The effect of weather parameters on different rice cultivars with various sowing methods of direct seeded rice was studied at Agricultural Research Station Farm, Vadgaon Maval, Tal. Maval, Dist. Pune kharif, 2017.The field experiment was laid out in split plot design with three replications. There were sixteen treatment combinations comprising of four sowing methods and four varieties. The results revealed that the pest population was lower in paddy variety VDN-99-29 (Phule Samruddhi) followed VDN-3-51-18 (Indrayani) and higher incidence with IET-13549 (Bhogawati) and RDN-99-1 (Phule Radha). The pest incidence was more with drill sowing at 22.5 cm and lower with sowing on raised bed (15-25×15-25 cm). There was positive correlation between maximum temperature, morning relative humidity, BSS, growing degree day and canopy temperature with incidence of leaf folder and brown plant hopper but negative correlation with minimum temperature, evening relative humidity. Stem borer incidence was not observed during the period of investigation. Therefore It would be, suggested to adopt sowing on raised bed (15-25×15-25 cm) to kharif direct seeded paddy variety Phule Samruddhi for minimum attack of rice pest with high yield production.
