Abstract:
The present investigation entitled “Effect of weather parameters on pest incidence of summer paddy varieties” was carried out during summer, 2014 at Agricultural Research Station farm, Vadgaon Maval, Tal- Maval, Dist- Pune. The field experiment was laid out in a split plot design with three replications. There were Eight treatment combinations comprising of two varieties VDN-3-51-18 (Indrayani), VDN-99-29 (Phule Samruddhi as main plot treatments and four fertilizer levels (F1-75% RDF through straight fertilizers, F2-100% RDF through straight fertilizers, F3-125% RDF through straight fertilizers and F4-RDF through Urea DAP form (57:29:00)+50 KgK2O) as sub plot treatments. The gross and net plot size were 2.95 m x 2.95 m and 2.55 m x 2.55 m, respectively. A spacing of 15-25 cm x 15-25 cm was adopted. Pest incidence and pest intensity (%) was lower in VDN-99-29 (Phule Samruddhi) followed VDN-3-51-18 (Indrayani) and higher incidence with IET-13549 (Bhogawati) and RDN-99-1 (Phule Radha). Pest Incidence and pest intensity (%) was more with fertilizer levels of 75% RDF through straight fertilizers and lower with fertilizer through Urea DAP briquette form (57:29:00)+50KgK2O. There was positive correlation between maximum temperature, morning relative humidity, BSS and canopy temperature and incidence of leaf folder, stem borer and brown plant hopper but negative correlation with minimum temperature, evening relative humidity, growing degree day.
