EVALUATION OF NPK FERTILIZERS ON THE DAYS TO SPROUTING AND GROWTH OF PHALSA (GREWIA ASIATICA L.)

Abstract

Soil and plant macro nutrients including nitrogen, phosphorus and potassium considered key nutrients for all kinds of the fruit crops, and proper fertilizer management is key factor for better crop growth and fruit yield. Current field experiment was laid out,to investigate the influence of various rates of NPK fertilizer on the sprouting days and overall growth of phalsa (Grewia asiatica L.).c.v Mera” under Lasbela climate conditions at Wayaro experimental farm Uthal during year 2016-2017. The field study was conducted in randomized complete block design (RCBD) included four treatments such as T1 (without fertilizer or 0 NPK), T2 (200 g plant-1), T3 (300 g plant-1) and T4 (400 g plant-1) with four replications. The results were indicated that T4 was increased days taken to sprouting (54.1%) and fruit yield plant-1(30.5%), while, days taken to flowering (36.5%) and days taken to fruit setting after flowering (13.2%) were decreased over the T1 (control) treatment. However, T2 and T3 were non-significant with each other but enhanced days taken to sprouting and fruit yield plant-1 as compared to T1. Conclusion of present study are that plant nutrition and balance fertilizer application according to plant needs and proper stage is most important factor for plant better growth and fruit yield under field experiments.
