Quality Attributes of Broccoli – F1 as Affected by Different Planting Dates, Nutrient Levels and Spacings under Cold Arid Conditions of Ladakh (India)

The experiment was carried out at High Mountain Arid Agricultural Research Institute (HMAARI) Leh of SKUAST-Kashmir during Kharif 2014 and Kharif 2015 to assess the effect of different planting dates, fertilizer doses and spacings on head quality attributes of F1 broccoli ‘Fiesta’ under cold arid Ladakh conditions. The experiment was laid out in split plot design containing one main factor (planting dates i.e., 5th April, 16th April, 27th April) and two sub-factors (fertilizer doses viz., 60:80:40 kg/ha, 80:100:60 kg/ha, 100:120:80 kg/ha NPK and spacings viz., 60×45 cm, 45×45 cm and 60×30 cm) forming a total of 27 treatments each with three replications. Chlorophyll, total carotenoids and protein recorded significantly highest values in D1 F3 S1 (5th April, 100:120:80 kg/ha, 60×45 cm) while moisture content recorded highest in D2 F3 S1 (16th April, 100:120:80 kg/ha, 60×45 cm). TSS was significantly highest in D3 F3 S1 (27th April, 100:120:80 kg/ha, 60×45 cm) while vitamin C recorded maximum in D2 F1 S3 (16th April, 80:60:40 kg/ha, 60×30 cm)...
