Abstract

The trial was conducted on pomegranate plants of cv. Bhagwa growing under high density planting system (3 m × 3 m) with three drip irrigation levels, i.e., 100%,75% & 50 % on pan evaporation basis and four fertigation levels, i.e., 100% RDF as basal, 100%, 75% and 50% recommended dose of fertilizer through drip. After field experiment for two consecutive years it is concluded that maximum leaf N and P content (%) was found under the treatment I3F3(100% irrigation at PE level + 75 % RDF through drip) whereas maximum Leaf K Content (%) was found under the treatment I3F2(100% irrigation at PE level + 100 % RDF through drip). For nutrient uptake, maximum N uptake (kg ha-1) (413.77) was recorded in the treatment I3F2 which was found to be statistically at par with I3F3, maximum P uptake (kg ha-1) (40.88) was recorded in the treatment I3F2 which was found to be statistically at par with I3F3, whereas maximum K uptake (kg ha-1) (313.35) was recorded in the treatment I3F2 which was found to be statistically at par with I3F3.

Conclusion

From the above discussion, it may be concluded since treatment I3F2 (100% irrigation at PE level + 100 % RDF through drip) was found the best among all the treatment combinations, as it recorded maximum nutrient content (%) as well as maximum nutrient uptake (kg/ha.).
