Field experiment were conducted at CSK HPKV Research Farm, Palampur during Rabi seasons of 2000-01 and 2001-02, to study the response of onion (Allium cepa var Patna red) at four sulphur levels (0, 15, 30 and 60 kg ha(-1)) applied through Gypsum and S95. The analysis was done to allocate the limited availability of sulphur for maximizing net profit over fertilizer cost. The results show that the dose of sulphur under its full availability is 43.02 kg ha(-1). But under its scarce availability the maximum benefit would occur when it is applied up to 32.11 kg ha(-1) followed by even distribution of fertilizer i.e. 20 kg ha(-1). The returns following sulphur application at these rates, would be Rs 69340, 73092 and 68700 ha(-1) respectively.
2000 - 01年和2001 - 02年冬季，在帕拉姆布尔的CSK喜马偕尔邦农业科技大学研究农场进行了田间试验，以研究通过石膏和S95施用四种硫水平（0、15、30和60千克公顷⁻¹）时洋葱（葱属洋葱变种巴特那红）的响应。进行分析是为了分配有限的硫资源，以实现肥料成本之上的净利润最大化。结果表明，硫完全可用时的剂量为43.02千克公顷⁻¹。但在硫供应稀缺的情况下，当施用量达到32.11千克公顷⁻¹，随后均匀施用肥料即20千克公顷⁻¹时会产生最大效益。以这些速率施用硫后的收益分别为69340、73092和68700卢比公顷⁻¹。
