Gujarat) during summer season of the year 2017 to study the role of potassium and sulphur on yield attributes, yield and quality of summer groundnut (Arachis hypogaea L.) under middle Gujarat conditions. The experimental soil was loamy sand in texture having pH of 7.80. The experiment included four levels of potassium viz. 0, 25, 50 and 75 kg K 2 O ha -1 and three levels of sulphur viz. 0, 20 and 40 kg S ha -1 . The experiment was laid out in a Randomized Block Design (Factorial) with four replications. Potassium showed significant effect on yield and yield attributes of groundnut. Application of potassium @ 75 kg K 2 O ha -1 produced significantly highest dry matter content at 45 DAS, no. of branches plant -1 , no. of pod plant -1 , shelling %, seed index, pod yield, haulm yield and protein content. Sulphur fertilizer also gave significant effect on yield and yield attributes of groundnut. Application of sulphur @ 40 kg S ha -1 produced the highest dry matter content at 45 DAS, no. of branches plant -1 , no. of pod plant -1 , shelling %, seed index, pod yield, haulm yield, oil content and protein content. Potassium in combination with sulphur showed significant effect on yield and yield attributes of groundnut. Combined application of potassium @ 75 kg ha -1 and sulphur @ 40 kg ha -1 resulted significantly the highest no. of branches plant -1 , no. of pod plant -1 , pod yield, haulm yield and shelling % of groundnut. On the other hand, in all the cases the lower response was found from the control treatment.

A field experiment was carried out during Rabi season of 2021-22 at Agronomy Farm, B. A. College of Agriculture, and Anand Agricultural University, Anand (Gujarat) to study the effect of sulphur and iron on growth, yield and quality of chickpea. The experiment was carried out using twelve treatment combinations consisted of four levels of sulphur (0, 10, 20 and 30 kg/ha) and three levels of iron (0, 5 and 10 kg/ha) which were tested under randomized block design (factorial). Results of the experiment revealed that the treatment receiving 30 kg S/ha significantly increased the plant height, number of branches/plant, number of pods/plant, seed and haulm yield of chickpea as well as crude protein in seed. Among different levels of iron, significantly maximum plant height, number of branches/plant, number of pods/plant, seed and haulm yield of chickpea were found with the application of 10 kg Fe/ha.
