Then CuSO4 and K2SO4 (1.0 g each) were added as catalysts into the flask.
Keeping in view the facts stated above, the response of tomato plants at early growth stage to soil- applied K fertilizer (K2SO4) in terms of their growth, production of biomass and accumulation of K were studied.
Besides, FYM and PM, soil provides phosphorus and potassium as their original quantity and for meeting the additional quantities of these elements, the sources used were TSP (Triple Super Phosphate) and K2SO4 (Potassium Sulphate).
The highest significant stem height (109.9 cm) was observed in treatment 85% FC along with application of K2SO4 in a rate of 250 kg [ha.sup.-1] (Fig.

Organic C in the K2SO4 extract was measured by an automated total organic carbon (TOC) analyzer (500 model, Simadzu Inc., Japan), and total N in the extract was measured by Kjeldahl digestion.
O CBM foi calculado pela diferenca entre os teores de C das amostras irradiadas e as amostras nao irradiadas, sendo adotado um valor de Kc igual a 0,213 (ISLAM & WEIL,1988), que corresponde a fracao da CBM extraida pela solucao de K2SO4 0,5mol [L.sup.-1].
Scientists at Florida State University placed saturated solutions of KOH, K-acetate, Mg(NO3)2, NaCl and K2SO4 in dessicators at 25 C for 10 days to generate water properties (Aw) of 0.0823, 0.227, 0.529, 0.753 and 0.973, respectively.
