The effect of zinc (Zn), boron (B) and sulphur (S) on the yield and quality of groundnut in a field experiment with three levels of Zn (0, 5, 10 kg Zn ha⁻¹ as Zn-EDTA as basal), two levels of B (0 and 0.25% boric acid as foliar spray) and three levels of S (0, 25, 50 kg S ha⁻¹as CaSO₄.2H₂O) in a factorial RBD were studied. Basal application of Zn @ 5 and 10 kg ha¹ caused an increase in nut yield by 3.7% and 28.3% respectively over control, whereas, application of S @ 25 and 50 kg ha⁻¹ increased the nut yield by 38.3% and 56.6% respectively over control. Conjoint application of Zn @ 10 kg ha⁻¹ and S @ 50 kg ha⁻¹ caused an increase in nut yield up to 73.4% over the control. Results, therefore, revealed that conjoint effect of S and Zn towards nut yield was more effective than that of B application. Application of Zn, S and B significantly increased their nutrient uptake in nuts. On an average, S, Zn and B uptake by groundnut ranged from 11.4 to 21.0 kg ha⁻¹, 0.14 to 0.40 kg ha⁻¹ and 0.12 to 0.25 kg ha⁻¹, respectively. Integrated mode of application of Zn, B and S showed a positive interaction as yield increase with their uptake in groundnut. Oil content in nuts ranged from 45.3 to 54.4%, while iodine value ranged from 97.8 to 90.5%. Application of S and Zn significantly increased the oil content, while it significantly decreased the iodine value in groundnut. So, application of micronutrients <italic>viz</italic>. Zn and B as well as S fertilization could be a useful strategy not only to increase the yield but also the quality of groundnut.

A study was conducted to examine the nutrient content and their uptake of rice as influenced by the application of humic acid (HA) and poultry manure (PM). This experiment was laid out in a Randomized Complete Block Design (RCBD) with three replications. Three levels each of humic acid (0, 3 and 6 L ha -1 ) and poultry manure (0, 3 and 6 t ha -1 ) were applied. BRRI dhan39 was used as test crop. Basal doses of N, P, K and S fertilizers were applied. Both humic acid and poultry manure either singly or in combination significantly affected the contents and uptake of N, P, K, S, Ca and Mg of BRRI dhan39. The maximum content of N, P, K, S and Ca except Mg and their uptake were recorded from the treatment combination of 6 L ha -1 humic acid along with 3 t ha -1 poultry manure.
