“…Sulfur is a very important macronutrient for oleaginous crops such as palm because it is related to oil biosynthesis and formation of storage organs of saturated fatty acid (SABIR The lack of S in the oil palm can be attributed to the losses caused by the reduction of this nutrient through FFB and leaching. Losses caused by sulfur leaching are related to sandy soils and the high S mineralization rate in organic matter (GERENDAS et al, 2009;SABIR et al, 2015), common factors in crops in the state of Pará. In addition, sulfate fertilization sources such as organic and magnesium sulfate, as described by Matos et al (2016), and possibly ammoniacal N sources used in these plantations may not have been sufficient in the case of losses and the rate of extraction in the studied crop.…”

Oil palm is a hybrid formed from different genetic materials, where different genetic varieties possibly have different nutritional demands. The O x G hybrid is supposed to need more nutrient than the Afriacana palm. The diagnosis of nutritional composition is made by the method of diagnosis of compositional nutrients, which uses nutritional standards in cormercia plantations, this method also supports the recommendation of fertilization. The objective was to generate standards for the diagnosis of nutritional composition (CND) in oil palm for N, P, K, Ca, Mg, S and B leaf and to perform diagnoses in tenera and interspecific hybrids (O x G). The CND and Sufficiency Ranges (FS) method was used in 240 samples of plantations in Pará, up to 6 years old, as well as data on the yield of dried fruit cluster (FFB) and chemical analysis of leaves for N, P, K, Ca, Mg, S and B. Oil palm plantations are located in the Moju municipality, in the north of the state of Pará. Reference values were obtained based on the multivariate relationships between CND indices and nutrients. . Comparing leaf contents and degree of agreement (DA) with sufficiency ranges (SR). In both methods, the nutrient with the highest deficiency was S. The plots with tenera and O x G presented, respectively, more cases of B and S deficiency by CND. This method points out different nutritional needs among genetic materials, as well as may help better fertilization recommendations.

Aim The present research was conducted to investigate the effect of plant growth‐promoting rhizobacteria (PGPR) and deficit irrigation on quality and quantity of flax under field and pot conditions to determine bacterial efficiency and to decrease water deficit effects. Methods and Results Initially, in vitro experiments were performed to determine the growth‐promoting characteristics of bacteria. Then in the field, the effects of bacterial inoculation (control, Azotobacter chroococcum, Azospirillum lipoferum, Bacillus amyloliquefaciens, Bacillus sp. strain1 and Pseudomonas putida) on flax traits were evaluated at different irrigation levels (100, 75 and 50% crop water requirement). Bacterial treatments in the pot experiment were selected based on the field experiment results. The irrigation regimes in the pot and field experiments were the same and bacterial treatments included single, doublet and triplet applications of the bacteria. All the bacterial strains could solubilize phosphate, produce ammonia (except for Bacillus sp. strain1), indole acetic acid and siderophore (except P. putida). Field results indicated that the bacteria significantly mitigated the effects of water deficit. Compared with control plants, bacterial treatments increased the oil, linolenic acid, protein and sulphur content; the number of shoots and capsules; and the harvest index in the flax plants. Pot experimental results revealed that the combined inoculations were more effective than single inoculum treatments. Conclusions Bacterial inoculation alleviates deficit irrigation effects in flax plants. Significance and Impact of the Study The effectiveness of applying A. chroococcum, B. amyloliquefaciens and Bacillus sp. strain1 was confirmed, especially as a combination to protect flax against water deficit and to improve its nutritional quality and growth.

“…Indian soils contains about 30% of total sulphur in organic combination in alluvial soils where as in Mollisols of tarai region it reaches to 70% (Singh SK, Dey P, Latare AM, Singh S, Sharma PK, Singh CM, Singh YV, Kumar., 2015) [46] . Sulphur is deficient in highly weathered soils like (Oxisols and Ultisols) (Sabir M, Hanafi MM, Hakeem KR., 2015) [39] . Sulphur precipitation is found in the form of sodium sulphate or calcium, magnesium.…”

Sulphur is essential nutrient for every living cell; it is component of 21 amino acids which form protein.It is fourth key plant nutrient after nitrogen, phosphorus and potassium. Pulses are particularly sensitive to sulphur deficiency which gives low quality and less yields. sulphur plays a key role In chlorophyll and oil synthesis. Plants uptake sulphur only in sulphate form (so4 2-) and it reduces to form sulphur containing amino acids and other compounds. Application of sulphur increases the nitrogen use. Efficiency of N, P, K is seriously affected under sulphur deficiency. Field experiments in many agro climatic conditions shown that application of 30 and 40 kg S/ha -1 along with recommended dose given the highest yields and protein content in pulses. Moreover, this review highlights the availability of sulphur for profitable crop production, effects of different sources and levels of sulphur in pulse crops, effect of sulphur on various parameters and it also includes the sulphur absorption and translocation in plants. Moreover this review provides new sights to revisit the sulphur significance in pulse crops.
