Effect of Irrigation and N-fertigation Levels on Broccoli Performance in a Polynet House

The purpose of this study is to see how the microclimate of the polynet house, irrigation, and fertigation levels affect broccoli output. The experiment was set up in a randomized block design within bounds beneath a polynet house with 320 m2 floor area covered with 50% perforated green colour net. Plant height, dry matter production yield, and its attributes were found to be maximum in drip irrigation (1.0Epan) + 125 % N at all growth stages, as per effect of scheduled irrigation and fertigation levels on crop biometric performance. Drip irrigation (1.0Epan) + 125% N resulted in a high higher yield (22.02 t ha-1); while treatments drip irrigation (1.5 Epan) + 75% N resulted as in lowest yield (18.02 t ha-1).The treatment drip irrigation (1.0Epan) + 125% N had a maximum NPK uptake. Polynet house covered with 50% perforation of green colour is suitable for realizing favorable microclimate for broccoli cultivation. Drip irrigation scheduled at 1.0 E pan with 125%N in the poly net house is recommended for broccoli production in central Telanganaagro-climatic conditions as it maintained high yield and water use efficiency.
