Abstract:
A field experiment was carried out during kharif season for two consecutive years (2020 and 2022) at Regional Research Station, Anand Agricultural University, Anand to assess the direct effects of different rates of applied potassium, sulphur and KSB on growth, yield and quality of direct seeded rice under direct seeded rice-chickpea cropping system. The experimental soil was loamy sand in texture having pH of 8.15. The experiment was arranged in a randomized block design with factorial concept, comprising eighteen treatment combinations i.e., two levels of KSB (0 and1 L ha-1), three levels each of potassium (0, 30 and 60 kg K ha-1) and sulphur (0, 20 and 40 kg S ha-1) with three replications. The results revealed that significantly increased in the grain and stover yield of direct seeded rice was 5.6, 5.7, 5.6 percent and 4.2, 4.3, 4.3 percent with KSB 1 L ha-1, 11.8, 12.3, 12.4 percent and 11.0, 10.6, 10.8 percent with 60 kg K ha-1 as well as 13.6, 10.8, 12.2 percent and 10.7, 10.9, 10.8 percent with 40 kg S ha-1over control in 2021, 2022 and in pooled result, respectively. Application of potassium @ 60 kg ha-1, sulphur @ 40 kg ha-1 and KSB @ 1 L ha-1 recorded significantly higher plant height at 30, 60 DAS and at harvest and effective tillers m-1 row length of rice. The conjunctive use of potassium and sulphur significantly improved plant height at 30 and 60 DAS, grain and straw yield.
