A field experiment was conducted to assess the effect of drip fertigation and plastic mulching on Chilli hybrid Sneha - 7044 at Precision Farming Development Centre farm, Tamil Nadu Agricultural University, Coimbatore. The experiment was laid out in a randomized block design with 9 treatments and 3 replications. The treatments are consisting of 3 mulching levels of Black plastic mulch of 50 micron thickness, 25 micron thickness and No mulch, and 3 fertilizer levels of 80 %, 100 % and 120 % of Recommended Dose of Fertilizers (RDF). The results of the study showed that the different levels of drip irrigation and plastic mulching significantly influenced the plant growth parameters of chilli. Among the various treatments, Black Plastic mulch of 25 micron thickness and drip fertigation with 120% RDF (144: 96: 96 kg of NPK/ ha) recorded maximum plant height and number of primary branches of 86.27 cm and 8.00 respectively. The maximum yield attributes viz., green chilli length, 100 green chilli weight, number of fruits per plant and dry matter production of 12.21cm, 418g, 287 and 156 kg/ha, respectively were observed in Black Plastic mulch of 25 micron thickness and fertigation with 120% RDF (T3). The highest green chilli yield of 9410 kg/ha was recorded in the black plastic mulch of 25 micron thickness along with fertigation @ 120% RDF compared to other treatments. The response of Chilli on black plastic mulch with drip fertigation were found to have higher moisture conservation, high yield, maximum water use efficiency, maximum fertilizer use efficiency and higher weed control.
