. Effect of Precision Farming Techniques Involving Fertigation and Mulching on Growth Attributes and Seed Yield of Okra Var. Arka Anamika [Abelmoschus esculentus (L.) Moench].

Abstract

An experiment was conducted during rabi 2016 to the study effect of precision farming technologies including fertigation and black polythene mulching to know the effect on growth, yield and quality of okra [Abelmoschus esculentus (L.) Moench] seeds var. Arka Anamika at ICAR-Indian institute of Horticultural Research Hesaraghatta, Bengaluru. The experiment consisted of ten treatments were laid out in a Randomised Block Design (RBD) with three replications. The maximum plant height (115.52 cm), number of branches (3.10), stem girth (4.76 cm), leaf area index (2.76), number of dry pods per plant (14.33), weight of dry fruit (10.33g) and seed yield (15.30 q ha-1) was recorded with T4 - 150:75:150 N:P2O5:K2O kg ha-1 applied through fertigation (WSF) with mulch over un mulched treatment. The increase of okra seed yield in mulched treatment over the un- mulched treatments with fertigation was 16.91 per cent. Similarly the increase of seed yield under fertigation with un-mulched treatments over application of fertilizer through soil was 10.14 per cent.
