EFFECT OF DRIP FERTIGATION AND PLASTIC MULCHING ON THE PLANT GROWTH AND YIELD ATTRIBUTES OF CHILLI (Capsicum annuum L)
Journal Title: International Journal of Agricultural Science and Research (IJASR) - Year 2017, Vol 7, Issue 1
Abstract
Field experiment was conducted in 2013 – 2014 at Precision Farming Development Centre research farm, Tamil Nadu Agricultural University, Coimbatore. To study the effect of drip fertigation and plastic mulching on the plant growth and yield attributes of chilli (Capsicum annuum L). The experiment were laid out factorial randomized block design which included three fertigation levels 80, 100, and 120 per cent Recommended Dose of Fertilizers (RDF) and three different mulching treatments 25, 50 micron Black Plastic Mulch (BPM) and no mulch which were replicated thrice. In chilli maximum yield of 128 numbers of fruits plant-1 which is worked out as 12.27 t ha-1 was observed for the treatments T3. The total quantity of water applied uniformly to all the treatments was 75.83 litres as per the crop water requirement. Maximum water use efficiency observed in T3 (66.36 kg ha-1.mm-1). The maximum N, P and K fertilizer use efficiency of 109.95 kg ha-1, 164.94 kg ha-1 and 164.94 kg ha-1 respectively, were observed in T1. The highest benefit cost ratio was recorded under both T2 (BPM of 25 micron thickness with 100 per cent RDF) and T3 (BPM of 25 micron thickness with 120 per cent RDF). From economic viability point the T2 treatment registered results that were economically viable with highest profit. Increased yield in fertigation treatments might be due to better availability of plant nutrients and irrigation water throughout the crop growth period under drip fertigation system.
