NPK REQUIREMENTS OF TURMERIC FOR CULTIVATION IN PUNJAB

Turmeric (Curcuma longa L.) is an important commercial crop grown since ancient times because of its aromatic rhizomes mainly used for medicinal, culinary and cosmetic purposes. cultivated nearly throughout Pakistan Punjab province a major contributor to turmeric production. Fertilizer rates are great determinants the yield turmeric. Therefore, this study was conducted at standing point on nutritional requirements (NPK) produce high suggest solid adequate NPK dose production following long-term field experiments including confirmatory studies. Thus, in 2009 2011, five were performed farmers' fields, with treatments consisting nitrogen levels (0, 60, 120, 180, 240 Kg ha-1 ), four phosphorus 40, 80, 120 ) three potassium 80 repeated Randomized Complete Block Design (RCBD) assess fertilizer requirement. Based results obtained from two 2012 one rate (180 ha 1 (80, 160, 200, (40 replications as study-1 confirm In 2013 2016, studies farmers ' fields six 240, 280 replicates 2, 3, 4 & 5 The showed that by applying @180:280:80 ha-1, maximum significant fresh rhizome can be recommended trust farmers. It also established requirement much higher than N K particularly soil deficient available phosphorus.
