Performance of Different Percentage of Urea as Foliar Fertilizer on Growth and Development of Rice (Rabi dhan1)

Abstract

Nitrogen can dramatically stimulate plant productivity as well as yield potential of intensified agriculture system. The unavailability of Nitrogen fertilizer specially urea during critical period (sowing season, drought, flood.) hamper the rice production. It is noticed in literature that the effectiveness of nitrogen fertilizer increased if it is applied in plants through foliage along with soil application. Present research work was planned to evaluate this theme so that the loss of yield due to unavailability of urea can be reduced by foliar application at various growth stages of rice. A research work was conducted to examine the “Performance of different percentage of urea as foliar fertilizer on growth and development of rice (Rabi dhan 1).” at the Agronomy and Agricultural extension Department Field, University of Rajshahi, Bangladesh from December 2022-May 2023. Rabi Dhan-1 rice variety with six different percentage of urea as foliar application were used for this experiment. 1. T1= N0% Control, 2. T2= 65% of recommended dose (N 50% as SA + 15% as FA), 3. T3= 70% of recommended dose (N50% as SA + 20% as FA), 4. T4= 75% of recommended dose (N50 % as SA + 25 % as FA), 5. T5= 80% of recommended dose (N60% as SA + 20% as FA) , 6. T6= N100% Soil application (Traditional practice). The experiment was laid out in a randomized complete block design with three replications. The significant effect of liquid fertilizer was found on almost all the parameters under studied. All the phenological and growth parameters showed the highest performance in T4 = 75% of recommended dose (N50 % as SA+ 25 % as FA) and lowest in T1= N0% Control. The result showed that the phenological characters like plant height, total number of tiller hill-1 was highest inT4 while the lowest was in T1. Plant height was increased with the increase of the age of plants. Chlorophyll content increased slowly at the early stage of crop growth and later declined. All the yield contributing characters like plant height, total number of tiller hill-1, effective tiller hill-1, panicle length, number of grains panicle-1, number of filled grain panicle-1, 1000 grain weight and grain yield were varied significantly due to different doses of fertilizer application.
