Abstract

An investigation was carried outto study the response of marigoldcv. ‘African Double Orange’ to pinching and various nitrogen levels at Floriculture Unit, Horticulture section, College of Agriculture, Nagpur during monsoon season of 2017 in randomised block design with nine treatments of different levels of pinching and nitrogenviz., T1 – no pinching + 75 kg N ha-1, T2 - no pinching + 100 kg N ha-1, T3 - no pinching + 125 kg N ha-1, T4 - single pinching + 75 kg N ha-1, T5 - single pinching + 100 kg N ha-1, T6 - single pinching + 125 kg N ha-1, T7 - double pinching + 75 kg N ha-1, T8 - double pinching + 100 kg N ha-1 and T9 - double pinching + 125 kg N ha-1 replicated thrice. The results revealed that, significantly maximum stem diameter, primary and secondary branches plant-1 and flower yield plant-1were noted with the plants treated with double pinching + 125 kg N ha-1, maximum weight of flower, number of petals flower-1 and longevity of flower were recorded with the plants treated with no pinching + 125 kg N ha-1, whereas, the earliest 50 per cent flowering wasoccurred when the plants treated with no pinching + 75 kg N ha-1
