Experimental design and crop husbandry

The seed of the twenty-two genotypes were sown directly in sandy soil under the walk-in tunnel system on Nov 1, 2017. The tunnel length was 21.34 meter and the width was 4.57 m. The genotypes were grown in a randomized complete block design (RCBD) with three replications with a plant-to-plant distance of 30cm and row to row distance of 60cm. At the time of seed sowing, Di-Ammonium Phosphate (DAP) fertilizer was applied as a phosphate and nitrogen source@ 150 kg per hectare. In the first two months, irrigation was applied after every 14 days interval together with urea fertilizer application @ 100 kg per hectare. After two months, irrigation was used at the interval of 7 days together with the application of sulphate of potash fertilizer @ 100 kg per hectare. Antracol and Alliette fungicides (™BAYER) were applied preemptively and alternatively, as per company recommendations, once a week for early and late blight disease control.
