Nutrient management strategies through split application for optimizing growth, quality, yield and nutrient use efficiency in Jasmine

In a nutrient management, split fertilization play an important role to increase fertilizer use efficiency. Application of fertilizer at time of requirement leads to optimizing the yield and quality of lean season flowers. The experiment was conducted in tropical condition with five different treatments of split application of N, P and K at different growth stage of plant with Randomized Block Design and replicated five times. Application of 25%N+25%P+25%K in last week of December + 25%N+25%P+25%K in last week of March + 25%N+25%P+25%K in last week of June (T3) to jasmine plants resulted maximum plant height (187.84 cm), length of secondary shoot (90.10 cm) and plant spread in N-S (135.15 cm) and in E-W (132.63 cm) directions at 360 days after pruning. Plants treated with (T3) noted highest flower bud diameter (8.04 mm) and weight of hundred flower bud (34.20 g). Flower bud yield (7.51 t/ha) were obtained at 240 days after pruning and observed that lean season flowering yield as compared to recommended practices of application of fertilizer. Maximum available nitrogen in soil (231.53 kg/ha) are recorded in (T3) and phosphorus (69.03 kg/ha) 50%N+50%P+50%K in last week of December + 25%N+50%P+50%K in last week of March + 25%N in last week of June (T5) before 3rd split of application. It is concluded that T3 was found proper nutrient schedule to get better growth, yield and quality in Jasminum sambac.
