Effect of Temperature on Growth and Yield of Broccoli under INM

Sprouting broccoli (Brassica oleracea var. italica) is one of the most nutritious cole crops. Although broccoli is not so popular yet in Jharkhand, it is slowly gaining popularity during the last few years among the consumers. The study involved the effect of temperature on rowth and yield of broccoli heads grown during 2008–09 and 2009–10 under different weather condition with 19 treatments of integrated nutrients management. Elevated maximum and minimum temperature at fourth growth phase of broccoli reduced the yield (9–20 q/ha) and yield attributes during 2008–09 under all treatments. Negligible effect of temperature variation on yields of broccoli sown during both years was obtained under application of 50 Kg N (VC) + 150:100:100 kg NPK/ha(TA).Integrated nutrient management (INM) having chemical fertilizers applied along with organic sources of nutrients is an effective method for improving the crop yield.Application of 50 kg N through vermicompost + 150:100:100 kg NPK/ha(TA) gave maximum yield of curd.
