Balanced Fertilization for Improved Nutrient use Efficiency and Mulberry Productivity

Aim: To study the effects of balanced fertilization in improving leaf yield, quality and nutrient use efficiency mulberry.
 Study Design: Experiment was conducted randomized block design (RBD) consisting 7 treatments 3 replications.
 Place Duration Study: The present at Central Sericultural Research Training Institute, Berhampore ((Latitude 24º05ʹN & Longitude 88º15ʹE; 18 m > MSL), West Bengal, India two seasons during 2018 (July-August; September-October).
 Methodology: Existing S-1635 mulberry plantation (10year-old; 60 cm × spacing; net plot area: 32 m2) utilized. Experiments were (July-August, 2018; September-October, 2018) replications. this included, T1: 100% N-P2O5-K2O+S+Zn with Urea-SSP-10:26:26 + Bentonite Sulphur (8 kg ha-1) Zinc Sulphate (1 as BF; T2: 75% T3: N-P2O5-K2O alone (Urea-SSP-10:26:26); T4: T5: (Urea-DAP-MOP); T6: (Urea-SSP-MOP) farmers′ practice (FP); T7: Nutrients omission (Control). recommended fertilizer dose (100%) for irrigated production Eastern region is N-P2O5-K2O=67-36-22 ha-1 crop-1. All fertilizers applied equal splits on 15th 30th day after pruning.
 Results: This reveals importance N, P, K, S Zn sustainable productivity, which reflected by maximum values yield attributes, chlorophyll content yield. Further, (in terms total soluble protein sugar) significantly improved fertilization. Higher PFP AUE also recorded compound/complex than straight fertilizers; but exhibited remarkable enhancement.
 Conclusion: results prove that @ 67-36-22 (Urea-SSP-10:26:26) sulphur zinc sulphate effective productivity through enhanced efficiency. could be useful realizing an efficient management strategy cultivation.
