Brinjal Production under Drip Fertigation

A field experiment was conducted at Dr. PDKV, Akola during November 2017 to May 2018. The experiment was laid out in RBD with five treatments which includes four drip fertigation levels. The study indicated higher plant growth, more number of branches, higher number of fruits per plant and enhancement in the yield under all drip fertigation levels. Yield of brinjal was maximum in treatment of drip fertigation at 150 % RDF (T4) (557.10 q/ha) and found at par with treatment of drip fertigation at 125 % RDF (T3) (554.88 q/ha). It was seen that yield of brinjal in treatment T4 was found to be higher than that of treatment T3, which was statistically at par. But the advantage in treatment T3 was requirement of 25 % less amount of fertilizer. Considering requirement of less amount of fertilizer in treatment T3 than treatment T4; the treatment T3 may be suggested as a best treatment. Minimum yield of brinjal was found in treatment of traditional fertilization at 100 % RDF. Higher irrigation water use efficiency 7.33 q/ha-cm was found in treatment of drip fertigation at 150 % RDF (T4) followed by treatment of drip fertigation at 125 % RDF (T3).
