Brinjal (<i>Solanum melongena</i>) Fruit Yield in Response to Urea Super Granule Application

Abstract

Experiments were conducted to assess the effects of USG on the number of branch and fruit production, fruit length, weight and yield of brinjal (Solanum melongena: cv Shingnath), compared to prilled urea as N source. The study was conducted at farming systems research and development site, Palima, Tangail district under AEZ 8 of Bangladesh during 2000, 2001 and 2002 using randomized complete block design (RCBD) with five treatments replicated 6 times. The treatments were T₁₌ N₇₈P₃₆K₆₆S₁₇CD_3t (Recommended dose for high yield goal (HYG), N as prilled urea), T₂= N₇₈P₃₆K₆₆S₁₇CD_3t (Recommended dose for HYG, N as USG), T₃₌ N₆₅P₃₆K₆₆S₁₇CD_3t (N 10%< Recommended dose as USG), T₄= N₅₂P₃₆K₆₆S₁₇CD_3t (N 20%<Recommended dose as USG) and T₅ = N₆₀P₃₅K₆₀S₀CD_5t (Farmers dose, N as Prilled urea). USG had significant (P?0.05) effect on the brinjal fruit yield giving higher profits. Thus USG as N₇₈P₃₆K₆₆S₁₇CD_3t was beneficial for brinjal cultivation in terms of yield and economics.
