Abstract

Magic growth solution along with prilled urea in the rice leaf as foliar spray may save urea compared to soil application of urea alone. In this regard, an experiment was conducted at the Agronomy Field Laboratory of Bangladesh Agricultural University during Boro Season (December-April, 2015) to evaluate the effects of urea and magic growth spray solution on the yield and yield attributes of BRRI dhan29. The experiment consisted of ten treatments viz.,T1 = Control, T2 = 99 kg urea ha-1, T3 = 63 kg urea ha-1 + 2.16L ha-1 magic growth spray solution, T4 = 99 kg urea ha-1 + 5.66L ha-1 magic growth spray solution, T5 = 117 kg urea ha-1 + 1.44L ha-1 magic growth spray solution, T6 = 117 kg urea ha-1 + 5.66L ha-1 magic growth spray solution, T7 = 126kg urea ha-1 + 5.66L ha-1 magic growth spray solution,T8 = 132 kg urea ha-1, T9 = 132 kg urea ha-1 + 5.66L ha-1 magic growth spray solution, T10= 132 kg urea ha-1+ 2.16L ha-1 magic growth spray solution and laid out in a randomized complete block design (RCBD) with three replications. The results revealed that urea and magic growth spray solution exerted significant influence on the yield contributing characters and yield of BRRI dhan29 except panicle length, sterile spikelets and 1000-grain weight. The highest grain and straw yields (6.16 and 9.33 t ha-1, respectively) were obtained from T7 treatment which could be the resultant effect of highest number of effective tillers hill-1, highest number of grains panicle-1 and lowest number of sterile spikelets panicle-1. Grain yield was significantly and positively correlated with plant height, effective tillers hiil-1, panicle length and grains per panicle. Economic analysis showed that net return and benefit cost ratio (BCR) was the highest (1.41) in T7 treatment. Thus the overall results suggest that farmers may be advised to apply 126 kg urea along with 5.66L magic growth solution per hectare to produce economically highest grain yield of BRRI dhan29, under the agro-climatic condition of Bangladesh Agricultural University.Res.

Highlights

Rice (Oryza sativa L.) is one of the most extensively cultivated cereals of the world
Urea was applied at 10 DAT, 25 DAT, 40 DAT and magic growth spray solution was applied for three times. 1st spray was applied at 17 DAT, 2nd spray was applied at 29 DAT and 3rd spray was applied at 44 DAT
These results explicitly confirmed the results obtained by Singh and Singh (1986) and Alam (2002) who recorded a positive effect of increasing levels of urea super granule (USG) on plant height

Summary

Introduction

Rice (Oryza sativa L.) is one of the most extensively cultivated cereals of the world. It is the principal food crop of Bangladesh and constitutes 95% of food grain production in the country. At present the N fertilizer is costly Under these circumstances, it is important to find out the effective method of application of urea that would give higher yield of crops and reduce fertilizer cost. Panir (2014) applied magic growth solution in the rice leaf as foliar spray which saved 44% urea compared to soil application, increased absorption rate, improved soil health and increased rice yield. Broadcast application of urea on the surface soil causes losses up to 50% but application of magic growth solution in leaf may result in negligible loss. The objective of this study was, to investigate the effects of different levels of urea and magic growth spray solution on the yield and yield attributes of BRRI dhan[29]
