Effect of sulphur and nitrogen application on growth characteristics, seed and oil yield of soybean cultivars

Korean Journal of Crop Science 01/2005; 50(5):340-345.


A field experiment was conducted to assess
the growth characteristics, seed and oil yield of two cultivars
of soybean (G. max (L.) Merr.) cv. PK-416 (V
1) and cv.
PK-1024 (V
2) in relation to sulphur and nitrogen nutrition.
Six combinations (T
1-T6) of two levels of sulphur (0
and 40 kg ha-1) and two levels of nitrogen (23.5 and 43.5 kg
ha-1) were applied to the two soybean cultivars as nutrients.
Results indicated significant effect of sulphur and
nitrogen, when applied together, on the growth characteristics,
yield components, and seed and oil yield. Maximum
response was observed with treatment T
6 (having 40 kg S
and 43.5 kg N ha-1). Seed and Oil yields were increased 90
and 102% in V
1, and 104 and 123% in V2, respectively as
compared to the control i.e. T
1 (having 0 kg S and 23.5 kg
N ha -1). Positive responses of S and N interaction on leaf
area index, leaf area duration, crop growth rate and biomass
production were also observed. The results obtained in
these experiments clearly suggest that balanced and judicious
application of nitrogen and sulphur can improve
both seed and oil yield of soybean cultivars by enhancing
their growth

The apparent supply matching to demand is accompanied by an apparent linkage of nitrate and sulphate uptake at the whole plant level in barley, rapeseed, soybean and groundnut (Clarkson et al. 1989, Abdin et al., 2003, Jamal et al., 2005, 2006a). Under S-deficient conditions, reduced protein synthesis is escorted by the accumulation of organic and inorganic nitrogenous compounds. "

    ABSTRACT: Research experiments were conducted to resolve the physiological and biochemical basis of the effect of nitrogen (N) sulphur (S) and Rhizobium application on summer Arachis hypogaea L. Six treatments were applied in different N and S combination. Nitrate reductase (NR) activity and ATP-sulphurylase activity in the leaves were determined at various phonological stages, as the two enzymes catalyze rate-limiting steps of the assimilatory pathways of nitrate and sulphate, respectively. The highest NR activity, ATP-sulphurylase activity and yield component were achieved with the treatment T-4. Slightly differences from this treatment decreased the activity of these enzymes, resulting in decreases of the seed yield in Arachis hypogaea L. The maximum seed yield achieved in Arachis hypogaea L. at treatment T-4 could be due to optimization of leaf soluble protein and photosynthetic rate, as these factors are influenced by S and N assimilation.

    • "A number of studies on S requirement of the crop in relation to N have been reported (Jamal et al., 2005; 2006a, 2006b, 2009, 2010). There is a significant positive S x N interaction in relation to the oil content and yield. "

    ABSTRACT: To minimize the gap between the demand and supply of cereals, oilseeds and pulses, intensive efforts are being made to increase their production. As ever-increasing population and urbanization cannot allow increase in the land area under the cultivation of cereals, oilseeds and pulses anymore due to the pressure on land, hence, yield per unit area needs to be improved further. To achieve this objective, agricultural scientists have laid more emphasis on improving production of oilseeds and pulses through proper nutrition of the crops by evolving high yielding varieties and adopting improved agronomic practices as well as plant protection measures, etc. The most important constraints to crop growth are those caused by the shortage of plant nutrients. Sulphur (S) requirement of plants has become increasingly importance in India as well as world agriculture. However, to achieve high yields and rates of S fertilizer should be recommended on the basis of available soil S and crop requirement.

    ABSTRACT: Randomized field experiments were conducted to study the interactive effect of sulphur (S) and nitrogen (N) on seed, oil and protein yield of two cultivars of groundnut {Arachis hypogea: cv Amber : cv Kaushal, .} Two dosage levels of sulphur () and two dosage levels of N () in various combinations were tested as micronutrient treatments, . Results indicated significant enhancement of the yield components namely seed and oil yield as well as seed protein. Maximum response was observed with treatment (having 20kg S and 43.5kg N . Increase in seed and oil yields of 90% and 103% in , and 79 and 90% in , respectively were recorded as compared to the control treatment (having 0kg S and 23.5kg N ). Effect of S and N interaction was observed on protein, N and S content in seeds. The results obtained by these experiments clearly suggest that judicious balanced application of N and S could improve the yield.
