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

Abstract

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.

Evaluation of the Effects of Drip Irrigation and Fertigation scheduling on Tomato Yield under Polyhouse

“…It not only minimizes the humidity but also provides optimal growing conditions conducive for improved crop yield [4]. Drip (trickle) irrigation offers the potential for precise water management as compared to furrow and sprinkler irrigation [8]. It also provides an opportunity to deliver nutrients in a timely and efficient manner near the root zone (Fertigation).…”
