Abstract


The polyhouse experiments were conducted at High-Tech Floriculture and Vegetable Project, College of Agriculture, Pune during 2007-09 to study the effect of different sources and levels of potassium fertilizers on yield, quality and nutrient uptake by lilium (Lilium longiflorum) grown under polyhouse conditions with 12 treatments was conducted in clay loam soil having pH 6.07. Application of potash (through sulphate of potash @ 200 mg plant-1 week-1) to lilium flower crop (var. pollyanna) recorded maximum yield (7992 flower stalk per polyhouse) and net monetary returns (Rs. 77694 per polyhouse) which were at par with K+ (through sulphate of potash @ 250 mg plant-1 week-1) to lilium flower crop. Like number of leaves per plant, plant height, stem diameter, plant spread, number of flower stalk per m2, number of flowers per stalk, vase life of flower was also recorded higher with treatment of sulphate of potash @ 200 mg plant-1 week-1 while other treatment of sulphate of potash @ 250 mg plant-1 week-1 followed it closely. The uptake of nitrogen, phosphorus and potassium was recorded maximum at recommended potash fertilizer practice i.e. @ 200 mg plant-1 week-1. The nutrient status of the soil after the harvest was better when both sulphate of potash and @ 200 mg plant-1 week-1 were applied to lilium crop. Thus, it would be better to apply potash through sulphate of potash @ 200 mg plant-1 week-1 to lilium crop for higher productivity and profitability along with good quality as well as good soil condition
