A field study was conducted to investigate and ascertain the effects of boron and molybdenum with recommended N P K S Zn fertilizers (RFD) for sustained sugarcane yield in the sandy acidic soil in Old Himalayan Piedmont Plain of Bangladesh. Results revealed that the treatment $T_7$ having recommended fertilizers of N 120, P 35, K 100, S 25 and Zn 2kg $ha^{-1}$ + B 2kg $ha^{-1}$ + Mo 2 kg $ha^{-1}$ produced significantly higher number of millable cane (126.96\times10^3\;ha^{-1})$ except in $T_9$ with RFD + B 2 kg $ha^{-1}$ + Mo 4kg $ha^{-1}$, and higher cane yield (92.83 Mg $ha^{-1}$) among all except in $T_3$ with RFD + B2 kg $ha^{-1}$, $T_5$ with RFD + Mo 2kg $ha^{-1}$ and $T_9$ where the effects were statistically identical. The increase in cane yield by $T_7$ was $164.6\%$ over control. The treatment $T_7$ having RFD + B 2kg $ha^{-1}$ + Mo 2kg $ha^{-1}$ further gave the highest additional net economic benefit of Taka 16, 500.00 for added Band Mo at 2kg $ha^{-1}$ among all the treatments in the study.

A field study was conducted to develop an economically suitable combination of organic and inorganic fertilizers for sugarcane cultivation in sandy acidic soil of a commercial sugarcane farm under Old Himalayan Piedmont Plain of Bangladesh. Results revealed that the treatment $T_4$ which received $75\%$ of Recommended fertilizers (N 120, P 35, K 100, S 25, Zn 2 kg $ha^{-1}$) + 10 Mg $ha^{-1}$ Rice mill ash + Mg $ha^{-1}$ press mud significantly produced higher sugarcane yield (72.34 Mg $ha^{-1}$) among all the treatments except $T_5$ having $100\%$ of Recommended fertilizers + 10 Mg $ha^{-1}$ Rice mill ash + 10 Mg $ha^{-1}$ press mud, which was identical. $T_4$ also gave the highest net economic benefit at Bangladesh Taka 15,920.47 per hectare from the added nutrient management. Thus, the integrated use with organic and inorganic fertilizer is highly essential for sustainable production of sugarcane in commercial farm of the region in Bangladesh, where it has been grown year after year.
