QUALITY AND QUANTITY OF MULBERRY LEAF INFLUENCED BY DIFFERENT METHODS, LEVELS OF IRRIGATION AND MULCHING DURING RABI IN EASTERN DRY ZONE OF KARNATAKA
Publication Date : 03/07/2016
A field experiment was conducted at College of Sericulture, Chintamani, Chickaballapur district, Karnataka, India during rabi 2013 to know the influence of different methods, levels of irrigation and mulching on quality and quantity of mulberry leaf in Eastern Dry Zone (EDZ) of Karnataka. The results revealed that the mulberry leaf quality and quantity were significantly influenced by different methods, levels of irrigation and mulching. Among the methods and levels of irrigation, subsurface drip irrigation at 0.8 CPE recorded higher chlorophyll, relative water, protein, total carbohydrate content at harvest and leaf yield (8.64, 69.69%, 23.56%, 17.29% and 38920 kg ha-1 yr-1) than surface drip at 1.0 CPE (7.42, 67.06%, 18.78%, 16.93% and 35012 kg ha-1 yr-1) and micro spray jet at 1.0 CPE (7.98, 67.63%, 20.24%, 17.05% and 35617 kg ha-1 yr-1). Maximum chlorophyll, relative water, protein, total carbohydrate content at harvest and leaf yield (7.19, 67.21%, 17.09%, 16.66% and 35336 kg ha-1 yr-1) was noted in mulching than without mulching treatment. These results clearly showed that subsurface drip irrigation at 0.8 CPE and mulching increased the quality and quantity of mulberry leaf than surface drip and micro spray jet irrigation at 1.0 CPE by saving 20 per cent of water. In the coming years, subsurface drip irrigation may be more appropriate to realise higher quality and quantity of mulberry leaf in EDZ of Karnataka.
